When I was a kid I used to buy Stereo Review and read Julian Hirsch's reviews religiously about equipment I could never afford to buy. I appreciated the amount of detail he went into with regard to measurements and what those measurements meant from a practical standpoint. What you're doing on youtube feels like the next step in the review process. I still can't afford the gear (or justify the purchase most of the time) but I appreciate your approach to reviews. Keep up the good work. :-)

OK, so I'm writing this in real time as I watch. I'm incredibly pleased that you made a point of talking about room modes. I think people need to get educated on this as, on first glance, it may seem that the speaker is to blame but I can guarantee that if you took that same speaker outside, you would see a lovely response with no peaks or dips. I sold my original pair of speakers because I thought they were faulty due to this exact type of measurement. Fast forward a few years and now I know it is just my room and nothing else. This is what miniDSP is for... 😏

Thanks Ron, great vid.. Very cool on how valuable of using measurements to basically set your baseline for speaker placement so as not to set yourself up for a dissatisfied experience, but to realize the other factors involved.. ✌️

Ron, get a pair of jbl 305 monitors. Would like your take on how these measure and sound

Hey Ron, I fix aircraft for a living, & I use calibrated tools all the time.... are your microphones, meters & amplifiers calibrated? Just wondering, & if so, how often do you recalibrate them? Edit: ps, love 💕 the thumbnail for this video!

hey great video. i was following this series with great interest and I purchased the 1TD as Left and right and 2TD as a center channel for my home theater. Is the room measurement video as been made?

Oh, and you definitely do say "access" as opposed to "axis"... You've always said it so I'm used to it but I freaked out when I first heard it. 🤣🤣🤣

On the room response and speaker placement, the thing I have learned, first from Roy Allison and a program he gave me to help work this out, and then actually doing it - is to vary the distances from the woofers and port to ALL the room boundaries. The key thing is to avoid common even factors - if all the distances are a multiple of 2 or 4 or 8, then you will have problems, for example. If you measure from the center of each woofer and the center of the port - to the floor, and to the ceiling, and the wall behind the speakers, and to each of the side walls (from each of the speakers to each side wall), and to the wall behind you - and see if any of the distances are multiples of another of the distances, or if more than one of the distances can be divided evenly by 2, or 4 - then you need to try to change one of the distances to something that does not share a common even factor. If you can get all the distances from each woofer and the port to the room surfaces to all be odd numbers, or better yet be prime numbers, then it is less likely to have a resonance "piling up" or sucking out, at a particular frequency. The goal is to *distribute* these distances, so they all are different and all have different factors. Another issue that I'm sure you already know, is floor/ceiling bounce cancellation.

I live on measurements. Keep 'em coming.. 👌

I turned off the paved road. I'm going off access! Sorry… had to! Love the videos! Keep it up! Don't go pulling off axes on me! Whoops! Did it again! 👺

It would be interesting to do a vertical off axis measurement with the Maggie’s

Some cancelations in the 100-200 Hz range could be be related to a floor reflection interference.

Thanks for objective data, sometimes it correlates well, and shows how was designed a product ( sound signature)

Hey Ron did ever fix your room and if so did it help with the mid bass being too heavy

ok, I'm a little confused, are you saying somebody like myself who may not have the ear that you do would cringe when I heard the bass? For an average listener would the bass be distracting?

You are saying it off axis. That's why it sounds funny.

Based on your sound clips in chapter 3, they image quite well but the GR Research NX-Otica has set the bar much higher. I instantly heard the lower-midrange warmth and upper-midrange dip (built-in) and the room's bass nodes and nulls (not built-in). They consistently compress the attacks, suggesting fairly low efficiency. If your graph reflects 2.83 V input, they would average only about 85 dB/W. (CSS does not specify efficiency on its website.) Besides the high power requirement, potential buyers should also consider the kit which costs less than half the finished price.

please make more videos about how to use Clio Pocket

awesome CSD... you should try to flat that curve with linear dsp and measurement mic.. i dont like that big 2k to 4k hole in the FR and I wonder what create this.. maybe too far c2c between mid woofers cancelling each other in these frequencies.. what is the crossover point? maybe they did something bad in the crossover! or its the tweeter sensitivity that cant keep up with the 2 woofers in its low band.. if yes higher crossover point and smaller c2c between woofer would fix this.. would need to truncate the tweets and woofer... not sure why they never do it anyway.. its a shame at this price to have MTM without its c2c optimized if you could you open it, unplug a woofer and measure it bare? so we know if its the woofer or tweeter itself that dip or something else haha it could be null phasing between midwoofer and tweets at crossover point too..

Ron... you have a habit of saying access, instead of axis. There is no E in axis, yet you pronounce one. Axis is pronounced "axe-iss". Having said that, it was another great video. Keep it up!

How can they claim +- 1.5 db within 45hz-17khz?

Off-access! driving me crazy 😂😂

Ron, was that a Vegetable Police impression in the beginning?🤫🙄🤔🤗

access

I think the world of CSS Audio, and that won't change, but these measurements don't look good.
