I can't believe nobody has mentioned a Rossini overture. William Tell and The Thieving Magpie are but two of several that fit the bill.

Integrating different drivers, e.g. a woofer and tweeter, to create a seamless presentation is definitely a non-trivial exercise. Full-range drivers avoid this problem and can, for certain source material and at modest volumes, sound quite good. But the laws of physics work against the...

If I understand your question/proposal correctly, this is what the Klippel system does when it generates the Estimated In-Room Response, which is part of every review done by Amir and Erin (and probably others). Of course, it is only completely valid for rooms with the same dimensions...

I beg to differ. Although in the case of the Kii, the processing is both causing the latency and modifying the low end response/damping, one might have processing in the system that creates latency with no effect on damping whatsoever. Conversely, one could build a highly damped, passive...

The latency is a result of the signal processing necessary to make the time domain response so nearly perfect.

To get a perfect step response would require bass extension to DC. Short of that, you end up with sort of a right triangle shape. The best step response I have seen is the Kii Three. (Stereophile's measurements here...

The JBL M2 fits the bill. Not only do they offer multiple amp and DSP module options, you can also buy the speakers with no electronics and roll your own.

I think you'll find the consensus around here is that "pairing" amps and speakers really isn't a thing. Except for speakers that provide an unusually difficult load (and nothing from KEF falls into that category), as long as you have enough power given your speakers' efficiency and your...

For sale (US only): Massdrop THX AAA 789 headphone amp. ASR review: https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-massdrop-thx-aaa-789-amp.5001/ Like new condition. No functional issues. Comes in original box with all original packing material.

I think there are two reasons for this: Sparse recordings better highlight many of the things audiophiles like to go on about, such as decay, imaging, etc. It can be useful (as Dr. Olive points out), making it easier to isolate certain effects, but sometimes what is being sold as a...

I tried a Faital HF108R on the Studio 590 horn. It didn't go any lower, nor was it any smoother than with the stock driver. Don't know about distortion. A complicating issue is that there is a molded plastic sub-enclosure behind the compression driver (visible in the first photo of post #69)...

Curious to be sure, and worthy of investigation. But let's keep things in perspective. For most listeners, with most music, those differences above 10k will have minimal audible impact. Throughout the range where it really matters, the two measurements are in very good agreement. Hardly a...

Akasa Turing sells fanless cases on Amazon that are designed to take the guts of a NUC. They have different case models for different NUC models. I did this for my AV PC and it has worked out well and never gets too warm, but then again, most of the time it is only running JRiver so it is not...

To be clear, this is not just something I've read about. I've done it. On two different speakers. The results, both subjectively and measured with REW, speak for themselves.

But all that is really unnecessary. If you use something like Audiolense or Acourate, all you have to do is measure the acoustic output of the drivers and the software takes care of the rest.

As has already been mentioned, unless you're already a highly experienced speaker designer and proficient with advanced modeling tools, you should stick to copying an existing design. (That assumes, as stated, that the goal is an "end game" speaker.) And if you're not pretty decent woodworker...

The Music Room (www.tmraudio.com) in Erie, Colorado sells Canton. The only Vento bookshelf speaker I see on their site is the model 20 at $1,695.

In the electronics realm, I agree 100% (although I think #9 is essentially redundant with #5 and therefore unnecessary). With speakers, things are less straightforward. It's not that there's any magic or unmeasurable phenomena, but I'm not sure we know what a full set of measurements should...

With non-coincident drivers, any speaker can only be phase- or time-aligned at one particular axis, regardless of whether the alignment is done electronically or physically. This is why the vertical off-axis frequency response looks so bad. I consider a speaker to be phase-aligned on the axis...

I have a pair of JBL Studio 590 floorstanding speakers for sale: $500 firm. JBL's product page is here. Amir's review of the smallest of the Studio 5xx line is here. I have modified these by adding internal cabinet bracing and Sonic Barrier panel damping. No scratches, dings, or other...
