ROBERT 04XBLZ Posted January 28, 2009 Report Share Posted January 28, 2009 (edited) right now i have two btl 18 ported tuned around 30hz around 9.5 cubes. i was thinking about going with 4 15's not sure what subs yet say btls just so that its easier to answer my question. so 4 15s sealed around 11 cubes. or 2 18s btl ported both set ups will be running on dd z2lv. what will be louder and sound good?

NoFearX18 Posted January 28, 2009 Report Share Posted January 28, 2009 2 18" BTLs vs 4 15" BTLs.... simple... the 4 15's more cone area and 2x the power... Quote My Videos AQ + AA/Fi FTMFW!!!!! Link to comment Share on other sites More sharing options...

RamenNoodles Posted January 28, 2009 Report Share Posted January 28, 2009 BTL = sealed = no good. Dont do BTLs sealed. The woofers are not made for that and wont work too well in that type of enclosure. More cone area yes, but will need double the power you have now but with no port area. Upgrade to 2 22" BTLs when they are released and im sure you will be fine hah.

RamenNoodles Posted January 28, 2009 Report Share Posted January 28, 2009 That port area and box size doesnt seem right to me. You have 2 18s in less then 10 cubes. Unless you have gobs of power on them, try redesigning your box and I imagine you will see a world of difference in those woofers.
