Speaker sensitivity vs SQ
@atmasphere --...  A higher efficiency driver that can make 98dB with 1 watt and is 8 ohms is a different beast altogether. This describes the 15" drivers in my speakers at home and they cost $2000.00 each.These are field coil-fitted drivers, rig... 
Speaker sensitivity vs SQ
@clearthinker --I'd agree with poster @ctsooner here. Pro manufacturers, the more or less sole supplier for this segment, have developed and build their high efficiency drivers for decades now, and relative to their size, material use and R&D ... 
Speaker sensitivity vs SQ
@audio2design -- You don’t have to have a highly efficient speaker to overcome dynamic compression in normal usage.Now, before you tell me what I don’t know and need to know, consider the following:What system constellation as it pertains to minim... 
Speaker sensitivity vs SQ
Greg Timbers:Q: How has the sound of speakers changed over the years? Many yearn for the speakers of the past over those of today… what has changed? Distortion, materials, focus on sound characteristics?A (by Mr. Timbers): Speakers have generally ... 
Speaker sensitivity vs SQ
@mijostyn --Good post, but I'd have to disagree with below quote: A low sensitivity speaker can be very bit as dynamic as a high sensitivity speaker. It is just a matter of power. Sorry, but no. Anything approaching live dynamics calls for both ... 
Speaker sensitivity vs SQ
@audiokinesis -- This is almost exactly what I’m working on, and had hoped to introduce in 2020 but... stuff happened that year...Anyway I designed a large-format Oblate Spheroid waveguide using Earl Geddes’ equations, like you targeting a 700 Hz... 
Speaker sensitivity vs SQ
@djones51 --With active speakers and DSP box size and bass extension are being challenged in interesting ways. Look at the Develiat Phantoms down in subwoofer range with appossing drivers and a lot of watts. The Phantom's to me are more an inter... 
Bigger drivers = bigger soundstage
The OP headline doesn’t gel all that well with the described findings, it seems. Too many factors are at play determining "bigger soundstage" than mere driver size alone, though better "room fill" is more in line with the use of larger drivers/ove... 
Best Speakers You Have Ever Heard In Your Home
@sounds_real_audio -- It does seem like it is possible to own the dream speaker. Interesting that no one mentioned those really large and or really expensive speaker.My experience has been the same. Not my experience - that is, while my actively... 
"Musical" subwoofers? Advice please on comparing JL subs
As far as a sub amp goes (or run up to ~1kHz) the Class D-based Crown K2 is as good as any I've heard. When bridged it's supposedly a fine all-round amp not restricted to subs/lower to central midrange prowess only. As great stand-alone all-round ... 
Anyone ditch the sub after large speaker purchase?
@douglas_schroeder -- I make systems with varying numbers of 15" woofers, from none, to one dozen. Yes, that's right, one dozen 15" woofers. There are fundamental things that happen with LOTS of cone surface that simply cannot happen with less co... 
I Was Considering Active, Then I Watched This ...
@audio2design --Time I picked up on this:Why are you going on about something that 99.9% of audiophiles have no interest in doing, and 9/10 of the remaining 0.1% are going to screw up?To begin with most audiophiles seem to have no concept of activ... 
I Was Considering Active, Then I Watched This ...
@audio2design -- Unfortunately phusis, your view towards active speakers is simple, just the replacement of passive crossover to active crossover. There is far more possible in terms of active speaker development that cannot be implemented in thi... 
I Was Considering Active, Then I Watched This ...
@douglas_schroeder -- Further, so now it’s being said that you can have an "active" speaker without the amps in the box! Well, isn’t THAT a revelation! I always thought that was designated a speaker with an active x-over. That opens up questions, ... 
Audiophile system for Techno and Dance music
@rixthetrick -- Massive SPL, huge volume cannot possibly compete against a highly resolving sytem, even for Techno or any other EDM music.I am not saying my 400 watts per channel doesn’t perform, and cannot play loud. However I will state that low...
