Looking into getting rid of my Polk BD 12'' in polk's ported enclosure and getting Polk SR 12''.
Current Polk PA600.1 mono amp (400 rms @ 2 ohms) will also be replaced with PA1200.1 (800 rms @ 2ohms) to properly power up SR12''
Will start practicing fiberglass enclosures to build fg sealed box for SR to fit it on the side of the trunk - main reason is to save space in the trunk and finally get a chance to make it look good with all those amps, wires and x-overs. BD sub sounds good but having that huge DB ported box is in a way of everything and there's not much i can do about it short of replacing it.
2 question for now, u can bet there'll be lots more as we go along haha.
1 - with this sub and sub box swap i'll be going from 360 rms in ported to 700 rms in sealed. We all know that all things equal ported is louder then sealed. Question is What should i expect SPL-wise from this swap? 700rms is basically double of 360rms but we'll have to subtract enclosure effect.
2 - all thing equal - how is fiberglass comparing to mdf when it comes to weight?
Yes, i know, it's very subjective question but let's say we have the same 10x10x10 box out of mdf and 10x10x10 box out of fiberglass - which one is heavier
