Matt : you know thats what I thought too, but apparently aluminum cones also have breakup. I never did get to put the strobe light to my a/d/s/ 312rs's I should do that when I get a chance. its hard to think that they could flex.
I don't listen so loud these days. After the damage i've done to my ears, altho I can still hear 16-17KHz and older crt tv's annoy me bigtime with their squeel. I do have a constant ringing in my ears i hear in dead silence.
Most of the damage came from the setup I had that used 2 18" woofers in sealed cabinets an 8" midbass, a large midrange horn and a tweeter horn, All were Electrovoice drivers
I know, your thinking "pro speakers" They never sounded boomy tho
I agree 100% on pro cabinets being made poorly. I swear by 3/4" or 1" MDF with plenty of bracing.
So, outcome is for car subs buy 12" drivers capable of long excursions with aluminum cones and put them in well built sealed cabinets eh?
If\when I pull the stock 6x9's out i'll try to get some pics of them under a strobe
I'm sure it'll look like the Atlantic.
BTW speaking of IB. I remember people building a wall between their backseat and the trunk and using the trunk as the sub enclosure, Hows this work out in the end?
