I recently went out a purchase a PSW350i to match my RT12's etc.. I was less then impressed with this subwoofer so I returned it and now I bought a old PSW150 off ebay. By the specs it looks to me like the old PSW150 is superior to the PSW350 and PSW450 for that matter. I haven't got the sub yet but does anyone else out there had a chance to compare the new vs. the old? Also anyone know which is better, the PSW150 or the PSW300?
