Dayton Audio DCS165-4 6-1/2" Classic Subwoofer 4 Ohm
Dayton Audio's rugged DCS165-4 6-1/2" subwoofer has all of the performance-enhancing attributes you would expect from a larger high-output subwoofer. With a vented pole piece and 4 ohm, 4-layer voice coil, this driver can handle up 100 watt RMS. The non-pressed paper cone is reinforced with Kevlar to increase stiffness, which promotes linear travel through the limits of its excursion. In addition, the pole piece includes a copper cap that keeps inductance to a minimum. The DCS165-4 driver is ideal for use in small multimedia speakers, portable speakers, or even automotive systems where space is at a minimum.
This compact active subwoofer kit is perfect for powering a compact 2.1 channel speaker system. The Dayton Audio DCS165-4 6-1/2" subwoofer is driven with 60 watts RMS for powerful output and incredible low frequency extension. The Lepai LP210PA amplifier also has 2 x 30 watt RMS outputs to power your left and right speakers. This kit is the perfect start to building your own amazingly convenient self-contained 2.1 channel system.
With an elegant compact enclosure, this 6-1/2" down-firing subwoofer kit is a great addition to any small stereo or home theater. Using a Dayton Audio DCS165-4 woofer in a vented down-firing configuration, this kit will fit low-key into any décor or under a desk to add high quality bass response and extension to your system.

I purchased the Dayton Audio DCS165-4 6-1/2" Classic Subwoofer (4 Ohm) to replace the aging subwoofer in my old 2.1 system, and I couldn’t be happier! This subwoofer completely revitalized my setup. The bass is punchy, clean, and tight, far exceeding my expectations for its size. Installation was straightforward, and the build quality is excellent. It paired seamlessly with my existing system, and now the sound feels rich and full again. Whether I’m watching movies or listening to music, the low-end response is fantastic without being overpowering. If you’re looking to breathe new life into an older audio system or build something new, this subwoofer is a great choice. Amazing performance at an affordable price. Highly recommend!

Replaced my factory install Fender subwoofers in my 22 Nissan Frontier and improved the low end sound by a good measure. Fit perfectly in a 6.5" placement without modification. Next steps are to replace the truck amp and boost the 100 watts (2x50) to 400 watts music power on the sub channel. Will calibrate output gain to these so they don't clip and will parallel wire them so they run 2 ohm on the sub channel output. Love them so far.

I bought this to pair with some Klipsch RP-600M bookshelf speakers for my computer desk audio setup and I couldn't be more happy with it. I put it in a 0.5ft^3 ported box with a 2" port tuned to 37hz and it sounds amazing and hits hard. I'm running it off a Fosi Audio TP02 amp and it gives it more than enough power. I added a photo of my box design if anyone else wants to reproduce it, it can be made with a single 3/4" 2ftx4ft piece of MDF you can get from Home Depot for $30 and the port is a 2" PVC pipe cut at 10". Couldn't be happier with this little sub, it has exceeded all of my expectations for a small subwoofer and i highly recommend it.
