So far I'm definitely impressed. It can be very difficult to locate a drop-in replacement driver for a specialty enclosure, especially when the OM is no longer in business. I have a sweet little Pinnacle SubCompact6 mini-sub that I have enjoyed in office and bedroom systems over the years, but the voice coil developed distortion. Searched the web options for a true 6.5" subwoofer and found this Rockville. Measurements were close, but obviously so are tolerances in a 7" cube with lots of amp hardware installed (200W with physically separate transformer mounted on the bottom of the box). That transformer was the rub, literally. Even with the magnet boot removed from the Rockville, had to use thick high density gasketing tape to space the transformer plate out about 1/8" from the bottom of the box to get the clearance needed for the magnet. Got it all buttoned up though, still have a tiny air leak as the Rockville rubber gasket on the mounting flange is a bit too stiff to really compress into an airtight seal, will take it apart again and probably replace the Rockville rubber gasket with foam gasketing tape. It could also be one of the original screw holes as I needed to drill new ones for the Rockville hole pattern. Of course, none of this reflects on the woofer or Rockville whatsoever, nobody told me it would drop in. The selling point was that the measurements were awfully close, but I also needed 4ohm and this is available in either dual 2ohm or dual 4ohm, so I chose the dual 2ohm and wired in series to get a 4ohm nominal impedance. Also, Rockville lists the sealed enclosure volume as low as 0.14 cubic feet, and my enclosure is roughly 0.19. I know the specs show it doesn't play much below 50Hz, but I'm listening to music with bass notes in the 35Hz range and it is handling them pretty darned well for a 6.5" driver. Have to call the project a success, need to figure out a grill of some kind because the factory original was way too shallow. Sound is more important than cosmetics of course, and it's probably going back under the desk where it was before anyway. Would recommend, and would purchase again for a similar install.

I had a Planet Audio sub in a small sealed box that I also bought on Amazon. I replaced it with this one and was worried that the airspace would be too small for this. I was really impressed at how much low bass this put out even in a small sealed box. I am considering making a larger enclosure. I am running 250 watts RMS to this sub. I don't think you could beat this for the money. I paid $45 for it. Very impressed.

Buena calidad, bajos considerables por el tamaño, buena construcción, lo movia com un taramps ts440x4 en bridge, alrededor de 350 rms y tenia que bajar la ganancia porque sobre excursionaba, pero por el precio esta bien, recomiendo alimentarlo con menos de 350 rms, con 300 rms se movería bien.
