View Full Version : 15" btl vs 2 18" bl's

12-01-2008, 04:40 PM
what are the pros and cons.what could i be expecting from both with the right electrical and power.i have the btl and a crunch 3000d pro now and love it but cant feed it the right power cause of electrical.was planning on getting a new alt soon or sell the btl and get 2 18" bl's get the alt later and run these on a aq2000
need some help.what size alt would i need to run the crunch at full or close.

I would get the alt first because you would need it for either setup and then up the cone area later

i just ordered it so now which will get louder.im sure some of you will say the bl's but i was wondering will they get just as loud as the btl but with lower tuning.

the bls will handle a lot more than that aq2000. i have 2-15" bl's and im pushing 2-aq2200 strapped and they handle no problem.

well i have a crunch 3000d-pro now but was going down an amp but wasnt sure maybe i might just keep the crunch and get the bl's.do you think they will be loude then the 15" btl even though its no muh power going to one sub

12-02-2008, 11:15 PM
Yes the bl's will b alot louder then the btl 15 more cone area.

Lets just trade u give me the bl's i will give you my btl.

Shavenblazer, if you aren't happy with that BTL you're crazy. :)

Yes, 2 18s vs 1 15 should be much louder on the same power if things are done right.

It takes skillz to get a single 15 louder than two 18's off around the same power (assuming the 18's have a decent install...)

What kindof space are we talking about. Do you have enough room for 2 18's for a good size box.

12-03-2008, 09:43 AM
yeah the back seat was coming out.gonna do a sweet setup in back seat area have plenty room.

Lets just trade u give me the bl's i will give you my btl.

i will trade you btl's though if you want

This is a stupid question......

12-03-2008, 09:08 PM
why is it stupid im aware of cone space just wondering about power handling.i heard numbers with a 2 bl 18's and im not that far off wih my btl 15.maybe 1db off so thats why i was asking so how is this a stupid question your stupid [email protected]#$%

2 18" BL's if in the right box should be a lot louder atleast to the ear. i mean, 1 15" BTL you probably have what, 4-5cf box? 2 18" subs should be in around 12cf, with a lot more port. comparing apples to oranges, but i would go with 2 18 BL's because of the cone area.

thanks for the good answers guys appreciate it alot.I was just wondering because my btl is tuned to 35 hz and i like the higher bass notes when they hit.whats the highest tuning i could put on these
