Currently I am using two JBL PSW1200 subs (12”, vented, 120w RMS) for my front soundstage, and an eD A7s-450 near-field behind my couch to handle the low-end stuff below 50 hz (and provide some couch-shaking).
The A7s-450 does its job very nicely, and I was satisfied with my JBLs performance until I bought some Polk Monitor70II’s and they simply make the JBL’s sound dirty in comparison. But I can’t ask the Polks to play LFE as loud as a dedicated subwoofer (well I asked, but the answer was ‘no’). So I’d like to upgrade my JBL’s to something that’s more accurate and outputs SPLs equal to or greater than the JBLs, but my budget is very limited.
So here’s what I’ve been kicking around:
Replace the drivers in the PSW1200’s with better ones.
My choice is the Pioneer TS-W309S4 which seems to be a perfect replacement. I’m not sure about port noise, but here’s the driver file and project for WinISD 0.7 alpha (which contains the PSW1200 enclosure data).
Pros – Cheap; and I get to keep the PSW1200 enclosure which I like.
Cons – Driver doesn’t fit, I’d have to route out a larger mounting radius; and I’d probably be giving the amp way more driver than it should have.
Sell the JBLs and buy a pair of BIC F12’s.
Pros – Don’t need to do any enclosure modding; both amp and driver are a decent upgrade from the JBL drivers and amp
Cons – more expensive; no clue if it would actually outperform Option A in SPLs, accuracy and low-end extension.
So I need someone with experience to give advice or insight to help me decide. Thanks in advance.
