The quest for my hyper speaker - Very Large room dilemma

[GXAlan]

This would definitely be on the docket if I were to choose going the DIY route, which may be the case if I can't find something suitable.

Why not DIY with Meyer Sound or JBL Professional in that case?

Nobody mentioned the Beolab 90.

There are these measurements. Seems like it’s a great option if that’s in your budget. Would be good to get subjective opinions against your JBL 4349 and Focal’s.

Bang & Olufsen BeoLab 90 loudspeaker

Bang & Olufsen's BeoLab 90 is not a loudspeaker to take on lightly. Though its size49.33" high by 28.9" wide by 29.4" deepand weight (302 lbs each) meant a major disruption of my listening room, which is also our living room, my wife assented. Its price of $84,990/pair puts it far beyond...

Diy gets tedious and takes time if I wasn't retired and in my mid 30s with 70k In woodworking tools and plenty of time on my hands I wouldn't touch diy. But I do so here I am researching cld box design mdf vs ply ? Alu ? Vs mass dampening do I use rubber to dampen the drivers or nah or maybe hold the magnets with rubber too ?or should I use sorbothane its better then rubber right ? Poly fill vs wool vs foam vs butyl alu goop ? Bracing matrix, cld , dowels ? cardioid ? Should every driver have its own amp? dsp? Fir ? Subs ported, sealed, pr, tl, bandpass i missed a few options????? Cross overs outside the vocal range ? 2 way 3 way 4 way 5 way 6 way, synergy horn, mtm, line array ? Ctc distance .25 or 1.4? Cone material? Low le? high excursion All questions that need answers. What makes drivers sound fast ? Imd vs thd ? Amp choises class a ,ab,d,h ?That's just what I can think of off the top of my head all these questions need answers.

Would you rather see the complete results from a medical study where you can draw your own conclusion or only see the interpreted results?

Only if I’m a specialist doctor.

This first one is custom. This model was designed for use with subwoofer towers and is capable of some serious SPL levels. These are active. For a large room some more cardioid features would be useful.

This is a soon to be released model form Ø Audio. 15 inch Tonalab woofer with a custom 460mm horn and Tonalab carbon ring radiator. I think they may be planning for an even larger model. This has passive xo.

If you have a big room maybe with a lot of acoustic issues arising I'd recommend a floor standing D'Appolito speaker. This way you have an "audio lense" and avoid many ceiling and floor bounces naturally and have a much higher ratio of pure source material vs. reverb.

For visualising:

Plus it should be at least three way, better four way.

That's just my opinion, but I reckon this is probably the best idea if you don't want to get a reverb party.

Polars & dispersion on (page 17-19).

They likely cannot do 115db peaks at OP's desired distance. But their cardioid response, and flexibility to be able to go omni for background music, is perfect. Also, they look like art. I've heard them a dozen times. I think their "focused listening (narrow)" mode is lacking vs. dedicated hi-fi speakers. But they are versatile, so it's just a sensible trade-off.

But yeah I don't really see how you can hit the spl goals for that space without compression driver'd pro speakers, or, line sources.

Has OP considered JBL CBT1000? Would look quite nice with a refinish, and crossed to subs they can effortlessly do 128db in room. CBT too so should throw nicely.

Thank you so much for the info re Mini DSP, I did not know that at all. I use their products in 2 of my systems so perhaps I hay have to rethink it for bass correction. As for the hyperspeaker I am currently in the process of emailing various manufacturers to get the requisite data. If they provide and allow me, I will share on this forum.
It is a real privilage for me to live where I do. I am still in my mid 30's so the knees are holding well enough for 30ish days of snowboarding a year.
Also, I too respect people I disagree with but I tend to draw the line where there is actual societal harm involved. In regards to his views on the pandemic (and his comments on gender in his most recent article) as a physician and a blogger he really ought to know better due to his reach and the weight his words carry.

If you can find one, MiniDSP OpenDRC-DI has 6144 taps/channel FIR filter capacity. Btw, you don't really need high tap count for bass correction, IIR filters work better than anything else for frequency domain correction below 200Hz and even the cheapest MiniDSP can do that through PEQ as well as biquads. You need FIR taps to correct for crossover and box/port phase shifts in the time domain which should help with some of your speaker directivity problems.
