..its called a large ottoman.😉
-personally I find that my feet are always attracted to the edges of a coffee table, so an ottoman usually serves this purpose better. 😀
Interior designers tend to use and ottomans with "breakfast trays" for more stable support for drinks, etc. when required.
Under 5 mil. sec.s for both reflections.. that is tough. Its good to see though that the absorbers are substantially decreasing the back-wall problem.🙂
I have a short, almost square, coffee table (more like a Bourbon table) and an Ottoman on each side. That works well for all purposes.
Any idea of the price?
Surely convenient, but just as surely not necessary. I would prefer to do the adjustments myself as "automatic" implies a lot of compromises to me. There are algorithms that one can create that would do a job that is probably better than what one would likely get by hand. It all depends on how sophisticaed the software is.
It would be interesting to test and see if the automatic setup can do better than the manual or visa-versa.
I guess that in the long run the automatic approach will become dominate because the costs will come down and the algorithms will get better. I'd like to see them add some "reverb" into the box and then I think we'll see some real benefits.

Thanks! Is it available? Couldn't find it online.
From the manual: "You will hear a test tone from each subwoofer, one at a time." How can the necessary correction be computed when only one subwoofer at a time is playing?

What you do, and I've simulated this before, is measure the complex transfer function from each woofer to the measurement points. From this data you can calculate the best signal filter to achieve a flat response from the N sources. If there are N woofers to M measurement points and you do this at L frequencies then you will get M x N x L different complex numbers for each source to each mic position at every frequency. Now the problem becomes these N x M x L complex values may not be a viable filter - most likely not. So you need to "best fit" the L x M values to get N realizable filter shapes that you would use for each sub.
This is the ideal way to do the job, but there are also an unlimited number of ways that one could "simplify" it making it less than ideal. How JBL does it, I suspect that we will never know.
Since the system is linear, you can do each sub independently and know that when they are driven together you will get exactly what you expect. No problem there at all.

Thats convenient!
Retail price for the BassQ is $1,199 - not too bad for a digital device (crossover/eq/delay?) that comes with 4 mics and stands.
But I'm still concerned that it's really doing everything right. The mains should be measured too and not only the subs...
Best, Markus

I think that the assumption is that the mains have already been optimized, i.e. they are JBL.🙂
Maybe thats not too high for a "box" of DSP, but it is pretty high when its not necessary, only a convenience.
And why 4 mics? Can't you just move one around?

Who should then press the one necessary button for the automated process to start when he or she already needs to move a mic around?
Don't think everybody needs to get a PhD first just to be able to listen to great sound reproduction.

Have any of you used Audyssey?? I have in built into my HT Pre Processor. Using that system you do move the mic around. You start with the prime position and you can take measurements in up to 8 different locations in the version I have. It works damn good for movies.
The Velodyne system works with multiple subs as well.

All you have to do is download and read the manual. It's right on the JBL site.

As I have said before, ideally I would want a reverb unit. The Behringer has three independent channels as I recall, this should work fine.
My system has bass just the way I like it, and everyone else seems to too (there is another review by six people on my site) and I don't use special processors. I just don't believe in throwing money at a problem when it isn't necessary. I like my money too much I guess😀
