Rockville W65K9D2 6.5" 1000w Peak Car Audio Subwoofer Dual 2-Ohm Sub 250w RMS CEA Rated

Liked everything, the bass is comforting to the ears, gives me luxury car vibes and its very clear 😍 ive used the sealed enclosure box dimensions provided 👍🏼

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 bought the Rockville W65K9D2 to replace an underwhelming factory subwoofer in a compact sealed enclosure. The difference is night and day. This sub brought the low end to life — tight, responsive bass without any distortion, even when wired to the factory amplifier. Installation was straightforward with minor modifications: Trimmed the internal support post to fit the deeper magnet. Used sound deadening material to reseal the enclosure. Wired just one 2-ohm coil to match the OEM setup. No amp upgrades, no fancy processing — just better sound. For the price, especially here in Canada, this subwoofer offers incredible value. Highly recommended if you're looking to wake up your stock system without spending a fortune.

I have never expected such good quality of the sound and fabrication! Excellent product! I was about to buy the DS18 version, but this one has better characteristics. When building the box, the reflex tube must be calculated for a very high air compression. thank you!

This was a waste of money don’t not work

La verdad estos K9 suenan bien bonito tengo dos y les aseguro que muy buena potencia que te llagan al pecho les recomiendo muy buena
