recently here i blew my dx 12's....yes, its very sad. I have pushed them both at 125 watts each for about 8 months, carefull not to blow them(because of underpowering). Also i carefully broken them in. THEN i got my new amp, and pushed a CLEAN 400 watts RMS to each one, and they blew!! i always thought it was a lot harder to blow them with more power! And get this, i was at circuit city this weekend, looking at the new momo in the custom enclosure. The guy is demoing it for me when it starts making a mechanical clanking sound and then it stops working.... wich is what happend to mine! he was pushing it with one MTX 8100D amp. i was supprised. ANYways polk no longer puts out the DX models so my replacement is going to more than likely be the GNX....i feel like its a bit of a downgrade, but at the same time i guess i will give them a try, its better than nothing! but to make a long story and longer, do u guys have any kick ass box designs for two GNX 12's?? if i get them i am going to request DVC's and push 200 watts to each sub RMS. wow that was long....thanks !
