Beyma TPL-150
Excuse me for asking something probably answered somewhere in this long topic, but ... someone has already tested / heard this TPL-150 series Beyma tweeter model? I have a near-future project for a friend who probably would need something of this magnitude (maybe result in some info usable for Beyond the Ariel project). But the price of this tweeter is too high to go blind

: http://www.diyaudio.com/forums/multi-way/231551-beyma-12p80nd-tpl-150-a.htmlI might be wrong, as I haven't been decided. But I think I know what I'm talking about.
Why do you think I don't have such drivers? I have been listening to such speakers in the last few days. Except that it was not FR but 2-way with a tweeter. Last night I switched to my regular speakers and then I have that feeling again
My point was that audio reproduction cannot be perfect. That's why it is acceptable imho, to recreate the music with many ways such as adding 2nd order harmonics or with using underdamped enclosure and so on.
You tell that to Joshua. His speaker is one of that kind.
Do they sound the same to you?
With respect, I vehemently disagree. And would suggest that you're relying far too much on your room to "add" hall acoustics to recordings that should have them but do not.
My current small listening room is far from ideal, but it is lossy and (mostly) free from major reflections. Strangely enough, large hall acoustics are the least "messed up" by its flaws - small room acoustics take a real battering.
All this is presuming that the recording has actually captured the ambient sound of the room and is not some synthetic "close miked" dross.

Other than properly cooked food, served before it goes rotten, I prefer tinned spiced ham.
And your point was what, exactly?
It's fine to disagree
But it's not about me relying too much on room to "add" hall acoustics (and how that even possible). I'm not even listening to orchestra/opera.Many says that speakers do not sound good in anechoic chamber. I've never experienced that. But if we rely on reflections to create illusion of big space, to make it easy at least the room should be sufficiently big.
And I think that's the point. We expect all information is sufficiently included in the recording such that we don't need some kind of way to recreate it. No speaker box and no wall reflection...
I hear you 'brother'!
I 'chased' this 'sound' over the decades, quickly getting to the point where I could do a close enough facsimile of 'front row center' at a large cinema and concert hall with a large compression horn loaded system in an acoustically fairly large, treated space, which kept me satisfied 'OK' for decades; but getting the ambiance of sitting further back or up in a balcony or at an outdoor performance, especially in an amphitheater or at a local church's pipe organ symphonies, could only be partially achieved with multiple surrounds and synthesized 'hall', bass doubling down, etc, effects.
It was still so far shy of the live event larger than a piano bar or small jazz venue though that as 'life' slowly took my sound system away that to date I haven't given much thought to resurrecting this vintage system or replacing it with any mainstream technology beyond getting ready to DIY a modest 7.1 HT system, with the '.1' using multiple distributed subs.
All that said, having auditioned some of DSL products, I can close the gap enough to justify the time required to DIY a new system if I can make it cheap enough without audibly sacrificing SQ, which judging by some others projects appears to be doable.
Regardless, based on your postings, I can't think of any viable sound system upgrade for your problem unless there's been some major improvements in headphone technology in recent decades, though some folks are touting the new Atmos cinema sound system capable of closing the gap considerably.

GM,
Funny how people stress about the ceiling bounce and now here we go with speakers directed at the ceiling to bring more reflections into the sound field. I'm not so sure how two channel recordings are going to be optimized to work with these distributed sound systems. There is no one size fits all solution to every type of reproduction of music or any other audio application.

Hi,
I have not had a chance to compare the GPA 416-8B to the JBL 2245H, but I am very pleased with my JBL 2245H in 220 liters (app. 8 cu.f.) vented caps tuned to 30 Hz. For home use they sound clearly better than the Fane Colossus 18XB they replaced - probably at least in part due to their much looser suspension (higher Vas). JBL used to use the 2245H up to around 300 Hz in their large studio monitors. I guess that is their upper limit.
Best regards
Peter

No comparison IME, the 2245 is an 18" woofer whereas the 416 is a 15" [mid bass] woofer, i.e. the 2245's 'best' BW is shifted lower, so while it plays up into the mid bass/lower mids, it lacks sufficient high SQ HF response, especially off axis, for a proper XO BW overlap above ~350 Hz and only 250 Hz IME and I know of others that didn't like it even at 120 Hz when mated to an Altec A7/416 even though 800 Hz was the recommended limit.
GM
Agreed and for Atmos, one must have all the necessary ceiling, etc., speakers plus the necessary DSP controller/synthesizer to make two channel sources viable and theoretically, once this is accomplished, the other, lessor demanding sonic events can easily be replicated.
FWIW, the best large space reproduction with just two speakers I've auditioned was the original 901 system using their special demo LP in a room optimized per their instructions.

Inotin,
I don't know why you would even consider an 18" speaker if your bottom range is only going to be 50hz, in that case I would take a 15" driver every time. If you want really low bass while the driver is only loafing along then a large 18" speaker is a choice, but as you see if it is a pro-audio speaker like the JBL that is going to require a really large box.

Here it is. It's very basic and can probably use some refinement, but the effect does work for me.
What it did for me was to brighten the phantom center to match the sides - without changing the sides. Let me know what you hear, it may be different on your system.
If you sense an overall change in level, let me know. I did several different level versions to get it right. Don't remember which worked for me.
EDIT: I will try to make an impulse file with the shuffle high passed later today.
