We set this sub woofer up as a sealed box, though instructions are provided for size and design for both ported and sealed. It is hooked to a older 300 watt RMS Rockford Punch amp. Sound quality is very good. The cone and surround are excellent quality. I've got another P2 that is several years old and continues to provide great sound without evidence of the surround failing. The older unit (not purchased from this seller) did eventually require the flexible lead from the amp hook on the speaker going to the internal windings to be repaired via solder after years of severe use. I would say it's not a design fault, just something that I'd consider maintenance. With regard to sound quality, this unit seems very responsive to various frequencies and filter settings from the amp.

I just replace a kicker sub for this RF sub and it's far better than what I had. I'm happy with it and glad I chose RF.
