But it isn't, any longer. The dominant paradigm today is HT, which means in most cases mains highpassed to a subwoofer. (People like me running large LCR mains fullrange along with subs are an exception.)
I look at it as similar to the recent evolution in car-fi towards compact amps. I was complaining back in 2004 that car-fi amps were stuck in an ancient paradigm of bigger (size-wise) AB amps when the technology was around for compact, more efficient, and cooler-running Class D amps. Lots of industry insiders disagreed vehemently. But look at 2010, and all of the major players have compact and efficient Class D (or Class G/H) amps that are quite powerful.
So I suspect it's just industry inertia. I'll be surprised if 2015 most commercial mains aren't "bass shy" but more efficient than today's products.
What waveguide do you want?
1. Penngray - 15" EOS
2. LTD02 - 15" EOS
3. 3AMRecords - 15" EOS
4. Noah - 12" EOS (assuming it holds pattern control down to ~1.2 kHz or less)
5. Zilch - Minimum 12" EOS (+cab roundover) assuming there's minimal on-axis notch
6. Erich H - either
7. JoshK (AudioJosh) - either with preference for 15" EOS
8. Bwaslo - 15" EOS, but either ok. 1" exit CD.[/quote]
9. DS-21 - depending on cost (too rich for my blood and the incentive to swap out the 12" Tannoy DC's gets markedly lower), 15" EOS, 1" exit and throat-matched to a known-good CD (don't care which: B&C, BMS, Beyma, etc.)
My current mains are 19.5" wide and I can live with that size, and a 15" EOS plus roundover would fit quite nicely in that form-factor.
