ALPINE408 Posted July 28, 2012 Report Share Posted July 28, 2012 what range are you looking to play anywhere from around 30hz all the way to 60-80. i believe most songs are in the range of 30-50 for the main track. all i want is to broaden the range of what i already have. Then make a new box I'm guessing your useing a prefab Quote Have you ever had your woofers blown? Link to comment Share on other sites More sharing options...

Then make a new box I'm guessing your useing a prefab its not a prefab, haha. it's a poorly made sealed box at 1.07cuft(after displacements). you'd laugh if you saw it haha. i already have a design for a new box for that sub to make it ported, but i don't have the cash right now.. so i don't know what to do. this 8" sub thing is just an idea for now. seems most people say it's a bad idea lol. i may as well just get another 12.

Ian Macfadgen Posted July 28, 2012 Author Report Share Posted July 28, 2012 umm cant really make a bad sealed box unless it leaks i made my box in a way that wasnt very good and the side panels werent big enough so i decided to smother the cracks in tons of glue and caulk. im SURE it leaks air.

bkolfo4 Posted July 29, 2012 Report Share Posted July 29, 2012 Also, you're frequency range is dependent on the enclosure, not the sub. This is true many times on the low end, but the upper end is more the sub and crossover frequency. Quote Current system: 1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s Previous systems: 2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz. 1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

1boostup Posted July 29, 2012 Report Share Posted July 29, 2012 dont do it. they're going to be playing the same range of notes regardless. i don't get it. i have two 8" oldschool jbl's. they definitely did put out a better 'high' bass. the 12 can hit the lows much better but when it comes time to hit a higher frequency, it doesn't seem to do it nearly as well as the 8's did. You still have those 8"s and are they the old school jbl gti 8's ? Quote Link to comment Share on other sites More sharing options...
Sonic Posted July 29, 2012 Report Share Posted July 29, 2012 El oh el Why your add just throw some 6 1/2s in there to help with mids op, use a good pair of 8'' midbass driver along with a proper ported box and you will be happy. Quote Link to comment Share on other sites More sharing options...
