just another question
 

i've been wondering if anyone out there has 2 subs in their car,, one sealed and one ported

sealed for the full range of bass and one ported for the strong lows

would there really be any benefit to this?

I had a car with a pair of 15" subs in a 8 cubic foot box ported to 20hz with an additional pair of 8" subs in the rear deck... The 15s handled 60hz and down and the 8's were used for 60-120hz... (they were really being used as midbass speakers, not subs)

being sealed or ported doesn't change the optimal comfort range of the sub, so doing this with identical subs wouldn't sound very good IMO.

but a setup like the post above this stated would work, wouldn't be my cup of tea as I don't want any sounds above 80hz behind me, but it would definitely work.

Why not take the money you'd spend on the extra sub and box and invest it on some midbasses and put the midbass sound up front?

If you look at the size of a typical car's interior, it should be clear that frequencies up around 120Hz will still pressurize the entire cabin at once... and with the size of the radiating surface of a typical 8" speaker, directionality is not going to be an issue no matter what the size of the listening environment.... (although that is not to say that loading isn't a factor)

I agree with what you're saying, but I've heard very few set ups that pull it off properly where there wasn't localization issues with the midbass coming from the rear....again, just my opinion of course.....besides, just seems unnecessary especially when using a sub to do this, forcing it to play in the upper region of its "comfort zone"

cus tis cool to roll with anorexic front stage. :)

i just cant see myself putting that much work into making a space for an extra set of speakers up front on a vehicle that wont be around a whole lot longer
