I'm just kinda curious, whats the benefit to making those weird designs of subs people do? Things like 12 8 inch subs, or like 4 12 inch 250 watt subs. Anything other than wow factor?
Cuz I'm kinda interested in FILLING my car with 8 inch RE RE's - it would look pretty cool LOL
Really, having that many "smallish" subs is just for show.
But lets say that a pair of RE 8's does 120dB (generous). And you have 12 of them. Add 2 more, ~123dB. Add 4 more, ~126dB. You'd have to have 16 of them to hit near or more than 130dB. That's presuming a sealed enclosure is used. Port them, and add 3dB to that figure.
IMO...it would be a pain having to use up so much space to install 12 8" subs basically just for the looks with the side benefit of visually enticing every crackhead within listening distance to jack the stuff.
I dunno about others...but I listen to stereo systems not look at them. A nice tidy looking install is the goal and by keeping things simple and clean with a nice stealthy looking system where you can't even tell there is actually several thousand dollars of equipment onboard you are actually accomplishing something as well.
Of course there are two school's of thought...the high "bling-bling" crowd that run around rattling trunks and pi$$ing everyone off and those that just let the sounds speak for themselves in a nice stealthy sealed environment where the only ones who know what the system is like are those that are privileged enough to be riding inside.
Cameron knows the response on 8's are crazy, a buddy of mine uses them as midbass drivers in his truck, and I know the knew mustangs come with 7's in the door
