The HPM100's were for tin eared suckfish. I sold both back in the day and many HPM100 owners blew them up and came back to buy JBL L100's. Several years later the big bass of ported cabinets was WAY improved upon by the likes of EPI/EPICURE/Infinity, etc. Funny most of these "influencers" weren't even alive during this time.

I am an audio engineer. The reason a audio device has a frequency range beyond the human ear is not a gimmick. It's to prevent Total Harmonic Distortion which occurs at and around the 3db down point is not audible to the human ear. Example of this is with the Gamble EX56 Live Sound Console, it's frequency range is up to 35khz.

Perfect description of the function of super twitter. Congratulations and thank you very much for the information.-
@stephenhall3515 Жыл бұрын
Correct. The function is not to act as a driver audible to human hearing but to deal with the harmonics from the other units. Tracing the whole range of what comes from such as a string quartet demonstrates this well and the musicians can seldom believe that so much energy is present at frequencies they will never hear. The pure physics is actually very simple.

I'm an audio engineer also. Your logic is possibly not going to fit with a loudspeaker with a passive crossover network and with a super tweeter that only starts to come into effect at those supersonic frequencies. So with this speaker, we are no longer talking about neutral extension without the distortion that can come into effect, but we are introducing an additional loudspeaker with phase distortion throughout the range where more than one driver is outputting the same frequencies (so through the crossover points), phase issues introduced by the passive crossover network (there must, at least, be a HPF on both tweeters unless the supertweeter is piezoelectric, in which case the distortion it will introduce is going to be rather high anyway), and also we are still hearing the main tweeter reduce in output at the top of it's range while doubling that with the super tweeter SEVERAL INCHES AWAY simultaneously outputting the same signal, causing huge distortion, particularly as you move your ears around. Horrible design, this speaker, and while the supertweeter might be a clever design, it's use in this speaker is NOT reducing distortion but, if audible at all, then it is increasing it due to the bizarrely terrible drive placement on the face of the speaker, side by side, and with both speakers not even being mirror images for consistent stereo imaging.

The Pioneer HPM-100 speakers were my favorite from 1978 through 1986. I enhanced the sound quality by replacing the 22-gauge speaker wire with 18-gauge wire. I had the Pioneer SA-9500II, the TX-9500II, PL-550 direct drive turntable, the PL-5000 direct drive turntable, CTF-1000 three-headed cassette tape deck, and the RT-707. This components system sounded nice. That was the time when audio became a new hobby. Since then, I wanted to see the inside of a radio station and a recording studio. I acquired an interest sound reproduction by the view of an audiophile.

The HPM series was designed for High Power at a continuous level. The 'sticky' was an elastomer compound to keep the cones from destroying themselves as the transients actually did. Ergo, some speakers needed replacing when the elastomer broke down; mostly because of high humidity and heat. The sticky also kept most of the power isolated from the box so kept harmonic distortion down. It was also an less expensive way of doing all that. Wish I still had my originals!

The curious thing about many old speakers, and this Pioneer HPM series is driver placement on the baffle. No company does it this way anymore. Vertical alignment and center spacing should cause alot of phase issues at the overlapping frequencies of the mid-woofer to lower tweeter and surely to the supertweeter. I doubt very much that they have a uniform 180 degree dispersion. All.of that aside, they sound surprisingly good.

I've paired other speakers to my vintage components, including top line Energy Speakers and Klipsch. While they are good speakers, they don't hand a candle to the HPM's! In November, we moved from the Midwest to Florida. Unfortunately, my HPM 100's didn't make the trip. I saw them go into the moving truck, but they didn't end up at our home in FL. So either they got lost, but considering the quality of our movers, I have no doubt they stole them. I bought my speakers from a man in Wichita, KS for $450 total! They weren't mint but in exceptional condition and barely used. I've checked on Ebay what these are going for now, $ 1,000 - $2,000/pair. This just makes me sick to my stomach how these have gone up so much in value and now I can't afford to buy another pair. Add to that shipping costs and any damage they may get in the process. I'm so pissed I no longer own a pair to no fault of my own.

Nice informative video! I take small issue with the criticism of the super tweeter frequency. It's true the human ear can't discern 25KHz by itself, but what's more important is the overall harmonic envelope of the sounds like from wind instruments or cymbals. the high frequency driver can help recreate these overall sounds more accurately. That's why for example the newer modern JBL speakers like the S9900s have a 42KHz HF driver, and definitely sound better with modern 24-bit music. I just got a very mint pair 100Bs, and they sound excellent. BTW, try using a paper towel roll, and isolate the HPM super tweeter, you will definitely hear a weak hiss, like sssssssssss.

A friend of Dad had a pair and he played Boston's first album from a reel to reel player. I was blown away. Ever since that audition I was on course for the HPM 100s. I got my tax return and went to my favorite hi-fi shop. I told the owner I want a pair of Pioneer HPM 100s! He asked if I had time to listen to some speaker comparisons. Sure why not? They had one of those rooms with a bunch of speakers set up and a switch to change between them. He played some music on the HPM 100s and then switched to the Klipsch Heresy IIs. Now I had heard the Klipsch horns a few times and considered them to be my bucket list speakers, but at that time way out of my price range. When the music flipped to the Klipsch I was taken back. They sounded significantly better than the Pioneers. I was a little heartbroken, but bought the Klipschs anyways. I've been a Klipsch customer ever since.

I replace the tweeters in my HPM-100's a couple of years ago. When I would run a test tone, the tweeters made a sound like the voice coils were dragging on the magnet. I was surprised there was anyone that still had new ones for sale and they were exact replacements. Had my HPM's since the mid 70s.

I think there were some audio editing errors here. You point to the mid, and quote Pioneer about the tweeter. Then you point to the tweeter, and quote Pioneer about the woofer. And yes, the super-tweeter does have a moving part. The film itself is the moving part, using the piezoelectric principle. They do burn out, and yes, you can test them with a 10kHz test tone, which most people can hear. However, they contribute almost nothing to the sound, so if they're blown, just disconnect them and put them back in place.

FYI: among all the super tweeter comments below, it should also be noted that it reproduces the harmonics you can't hear, these harmonics affect what you DO hear and help to create more realistic sound. The harmonics you can't hear because they are outside your range of human hearing make things sound the way you hear them, Exampe: you hear a Sax compared to what an acoustic guitar sounds like. The harmonics you can't hear make things sound the way they are.

I have a set of Sansui floor speakers almost identical to these. Mine have a horn loaded compression tweeter with an L-pad though. And a dome tweeter. Two midrange drivers. 12 inch woofer. To this day, the best sounding speakers ( for music ), that I have ever had. Nothing comes close. Excellent for analog LP play back. Extremely efficient.

Well I'm a lone wolf here but here's my speaker experience. I worked for Heathkit during the 70s - 80s as a technician at the factory in Benton Harbor/ St Joseph MI. I eventually took a job at the factory store and we displayed and played all our audiophile products in a living room sized about 18' x 18' with sliding glass doors to close us off from the sales floor. The speakers were 4 AS-1373 200W rms speakers powered by two AA-1640 stereo amps also rated at 200W rms per channel . This setup, blasting 800W of Manheim Steamroller Fresh Aire music that rocked the room and your lungs, made the easiest sales pitch demo ever. 🔊

I was just looking over Heathkit equipment on eBay. This brought back memories of the little AA-1214 amp I built in high school. It's power output was rated much lower than the comparable Lafayette amp I owned at the time, but it had more punch and clarity. I believe that the Heathkit designs, while lacking glitz, did not skip on good electronic design, included hefty power supplies, and used quality electronic components. May have been better than much of the competition.

Great coverage and story, and love the extensive history you have of the HPM speaker series. I’d learned of them and the history with Mr Locanthi’s role of their development a little over 10 years ago when I’d scored a pair of the HPM 60 yes I enjoyed them they were great speakers and still kinda sleepers at the time. But they sounded still full and clear used them with a pioneer Sa 9500 integrated amp , TX 9500 tuner and 707 reel 2 reel, JVC QF series DD turntable with grado red cartridge, denon dcd 3000 disc player. They formed a very respectable combo!!

Very cool! I had read this history online some years ago, but it wasn’t quite as detailed. Your SX1250 and HPM-100 videos make me happy because it’s the combo I lusted for at 15 and finally bought about 20+ years ago. I’ll use them ‘til I’m gone and make sure they’re passed on to a new caretaker. They’re just SO satisfying to listen to and look at and the cool history adds to the appeal. Also, big shout-out to Audio Specialties and Inner Sound Audio in Portland, Oregon for reviving my vintage gear when I’ve had problems.

Got a Pionee SX-1010 for $199 on closeout in Okinawa in 1976. Paired up with Technics direct drive turntable, Sony TC-558 Reel to Reel, Pioneer SG-9500 EQ, Pioneer RG-1 Dynamic Expander and Pioneeer CS-99A speakers. Loud, sounded good but something just wasn't quite right. Then I picked up a pair of HPM-100's for $350 and everything and I mean EVERYTHING changed.Front row concert level no distortion ears ringing but hearing little things in the music I never heard before and It cerushed everybody. Sansui 9090DB, Kenwood, Marantz, JBL L100, Bose 901, JBL L65 Jubal, all fell before the power of the SX-1010 driven HPM-100's. I Wish I still had them.

Among "Audiophiles" (or "Equipment Enthusiasts"), one sure way to stsrt a polarizing speaker discussion is to mention the HPM-100, or anything by Bose....people who have never owned them usually don`t have a clue as to what they`re really like. I am currently running 2 pairs of HPM-100s, stacked and wired in parallel, powered by either a restored SX-1250, or a Carver M-500t amp. With either setup, the soundstage is absolutely HUGE, and sounds great for everything from quiet, near-field listening to "melt your face, Led Zeppelin concert" type volume levels. Yes, I do like these speakers....

I've been using Pioneer CSG-301W 12" 3-way speakers for probably 40 years now, and I love their clarity; I can hear distinction even between 2 guitars and 2 voices from the same person singing the same note at the same time. They are not heavy duty, but living in a condo unit, I don't turn them up really loud. I'm on my 4th receiver, a Sony 100 watt/channel. The other receivers died, but the speakers still sound good. Someday I may get subwoofers, but for the most part they sound good with my music at levels that don't get visits from the Police. When I got them, I was expecting to get smaller speakers, but these, even at only $80 each back then, were far clearer and crisper than anything else anywhere near their price. Recordings of birds and crickets sound to me like I m outside hearing the real thing. These are showing signs of external wear, but they still work fine. I use "milk carton" type stands. as they lift the tweeter and miss to the right height. and they're easy to adjust and move. They slao don't transfer bass to the floor. Yet are still very clear and clean, but I'd like a subwoofer. When I toe these in and listen to a BluRay Concert with my tVs back-mounted woofers and tweeters, give a really good image of sound stage. My current Pioneer woofers start rolling of at about 55 Hz. I tested my ears, and my hearing goes up to a little over 15k (Amazing cwhen I think of the values I ve put my ears through).

I bought a basic stereo in my early years in the USAF. They were like hot-rods, everyone trying to best the next guy. My system was a pair of HPM-100s, an SX-750 receiver and a PL-530 turntable. My only regret is not getting a larger model receiver such as the SX-1050. I think I purchased all this in 1977 and the speakers were about $330 if memory serves. No internet back then, but we would surf through all the audio magazines and try to find the best buy from mail order companies. Still have all these components BTW plus others from a few years later, to include an Akai GX-636 10.5" reel-to-reel tape deck.

I purchased my pair HPM 900's in 1982. Exceptional sound and quality to go with my Realistic STA-2080, also purchased in 1982. I also added an ADC Sound-Shaper Ten EQ. In 1993, I turned up the volume a little too high on the stereo and blew out the Styrofoam on the woofers on both speakers. I replaced the woofers with two Cerwin Vega's direct from the L.A. manufacturer. Unfortunately, the speakers did not line up with the mounting screws. However, they were heavy enough to sit in the hole without moving.

If you can hear anything above 12,000Hz (the crossover frequency to the supertweeter) you should be able to hear that the supertweeter is working. I remember putting my ear against one (at low volume) when I used to sell these back in the day and they definitely contributed to the audible part of the spectrum! Even the discerning customers could hear their contribution when noting their very high crossover frequency.

I drive mine with an Hitachi SR-903 and it is possible to do near permanent hearing damage while enjoying crystal clear music if I am careless.

I have owned my HPM 100s for approximately 1 month now. Picked them up for $150 at the flea market from someone who did not know what they had. They are in excellent condition, with the one exception being that they lived their entire lives upside down. I assume that whoever had them was doing that because of the popularity of JBL4311s, which have the tweeter on the bottom. The end result is that my speakers, although in nearly pristine condition, have scuffs and marks on the top, which used to be their bottom. I absolutely adore the sound of these speakers, and it has caused me to sell a pair of speakers which I have owned for close to 10 years. They are MB quart and I swore that I would never sell them under any circumstances. Well the circumstances have arisen, and they are for sale. I love my HPM 100s. I will say it loudly and proudly.

The first edition HPM-100 were my prime driver when I finally reached my audio goal in 1978. I had various receivers before I sold them off to afford my phase linear system. While the phase linear really over-drove my HPMs, I was careful not to overload them. I had those speakers for 30 years before they finally stopped working. I had owned jbl and bose speaker systems before I finally was happy with my HPMs. I considered them the very best speaker on the market for that time period. I lived on the third floor of a walk-up apartment back then, getting those speakers up the stairs is a nightmare I still have from time to time.
