Those 2 posts were a yawn.
Let's see if I get this right:
Looks and size don't matter, unless you dig way too big and unsightly. Performance per dollar is a newly invented criteria, which has yet to be defined. (IOW, why stop where you have? Let's just leave the caps raw MDF and leave the silo natural cardboard, eh?) Ported alignment offers deeper extension with significantly less distortion.
Prove it. And, let's attempt to be a bit more specific than 'significantly less distortion', 'deeper extension', 'price per performance', 'more linear FR', blah, blah.
I'll use 8 of THESE
18" drivers in an IB powered by THIS
240 watt plate amp.
That puts me right at $1,000.00.
Or, 16 of THESE
15" drivers in an IB, powered by the same 240 watt amp.
That puts me at $1,200.00.
Postulate away. Would I actually build such a system? No way, but your tired argument forces one to offer not-gonna-happen examples, doesn't it?
The simple fact is that no ported subwoofer has ever topped any list except the big Dynaudio quad 12", which sort of blows your price per performance gig out the window, and it still doesn't compete below 20Hz.
I know, I know...you'll show me dozens of what-ifs, projections, models and misquoted theories, but no actual proof of the goof ball claims you make. I deal in reality, which is flat in-room across the entire Dolby LFE spec, not a spec you invent for reasons that serve your agenda. That's gonna cost what it costs...period. If it comes in a small package that actually looks good, how is that a bad thing?
The real truth of your philosophy is: Cheaper is better if you don't mind a huge box, port compression, lopped off low end, steep roll off and excessive non linear distortions.
