This high-end Full Range Stereo Speaker set was designed around the Markaudio CHR-70 4 inch full range driver in a front slot ported bass reflex enclosure. The goal was to have a premium quality point source full range speaker with premium quality parts that will not require a correction or crossover circuit. The Markaudio drivers are surely very good and perform with low distortion and overall very flat frequency responses out of the box, and are perfect for this application. When following the build plan, it can easily be built with everyday woodworking tools and by someone that does not have advanced woodworking skills.

Late to the video but wanted to add that slot ports and multiple ports vs single round have varying surface area and boundary layer effect. I have found tight slot ports or narrower shapes can take more energy + lower the tuning to a degree. Most important is rounding the port exits and making them symmetrical end to end

One of the benefits of using a full-range driver, as Bose discovered ages ago, is that it's fairly simple to use DSP to correct the frequency response to tune it as you wish. You can also use a passive tuning network of various parallel notch filters or other filter types to attenuate the output as you need to get the result you want if your combination of driver and enclosure don't get you there on its own. Tuning a speaker becomes a bit more manageable when you've only got one to deal with.

A way to hot up your FR drivers for more khz. Get some cheapies for practice. About 3 mm out from the start of the cone, make cuts right through the cone with a sharp razer blade. The cuts are like 8mm long (with 5mm gaps that are not cut) all around thecone. And repeat the process about 1 cm out from the start of the cone. And do it on the dust cap or remove it and construct a phase plug. Or with drivers with (stationary) phase plugs and (no whizzer cone).They are chiffy and you won't need one. Buy drivers without the whizzer. Best treble you ever heared (better than tweeters). Tweeters have air trapped inside, making them sippy. 😅 You get tweeter performance too! Along with my othet RANT, drum kits never sounded better, Cymbals so crisp (yet not fatiguing) and skins so addictively real! With the semi open sound (which also gives more khz) You get the benefit of the dipole open sound, but warm (cos of the box). Bass level is not compromised at all. 😅 You can hear the skin on the kick! It's PURE POINT SOURCE cos even the bass reflex system is point source. For the purists it's a breakthrough cos they can have more bass that is still point source.

Try blocking the bass vent and remove the driver and put a 2" deep bass vent tube on the inside of the speaker hole. Now replace the speaker screws with extension screws, like 1" longer. The driver will be mounted over the hole, not in it, ok. Use soft thin sprinkler hose as spacers between the box and the dtiver. Have the top gap berween the box and the driver like 1/2" and the bottom gap is lIke 1". If you try this you will like it! And want to make more.The hard part is the size of the gap. The sprinkler hose is flexible, so you can easily fine adjust the gap with a screwdriver (and you can cut many different size spacers to experiment) (that's why I said "like" before each gap size). Try this quick experiment. Try freely holding the driver over the hole wnile playing. You will get a "wha-wha" effect (like sometimes in house music). Tonal balence changes in the voice sound. Go predominantly by the voice sound to get the best sounding gap. And it''s important to bass vent the speaker hole before mounting the driver to stop it from sounding bonky.

Unfortunately the sound chain is all we have in this case. I don’t have any preconceived ideas about which is better but the only thing that changed in the many layers of sound reproduction was the dsp correction. I heard a consistent difference between the dsp corrected and straight playback and wanted to share.

With the DSP. It definitely sounds better in my opinion. Especially when it comes to the female vocals.

I like all of your builds, straight forward and nice woodworking. However, I suggest you use other screws. The builds are so nice, but the screws are "screwing you over" on the looks :) Attention to detail. There are black socket head screws wich are self tapping, os simply machine screws with thread inserts. That would elevate your builds a lot :) Also I have one question. Would the Arylic work also as 1 amp per box? To power mid and tweet with one plate amp and then feed the other the same signal? I have Hypex plate amps, but for a smaller build the Arylic would be fun. Thank you and keep up the great work!

Beautiful little bookshelves! I've always enjoyed a good point-source speaker, and these drivers seem like they may lend themselves well to a Critical Alignment system. I will say, I'm not a fan of the DSP adjustment. It comes across as too flat and "soundtrack-y." In their natural form, I can sense a lot more natural presence and character to the sound. I definitely see what you mean about the "forward" midrange. Fairly characteristic for a lot of smaller aluminum cone drivers, though, and I've had good luck in the past playing around with small rubber buttons glued to the back of the cone. You give up a hair of detail in the high frequencies, but it can really attenuate the ringy/bright midrange and bring it in line with the rest of the driver's capabilities. :)

I got a pair in 15.7l folded TQWT with BSC and in only takes about 2dB bump in the low range to make them sound much bigger than what they are. Sweet little driver. BSC is about 6dB with 8 ohm resistor and 1.4mH coil.

@attainableaudio4533 2 жыл бұрын

Probably has to do with the power response, seeing as it is a full range and will be more beaming in the treble which mean less highend overall into the room, so if you use the dsp to take out too much treble it means the off axis response will be too dark. If using dsp you should see what the off axis response is like and try to adjust for that instead. Great looking speaker!
