Working,deep bass.Comes with power cord.About the PSB SubSeries 5iExperience tight, punchy bass in your home theaterPSB designed the SubSeries 5i to deliver great bass in any small-to-medium room. They carefully designed the 10 woofer and paired it with a 150-watt internal amplifier. The result is extremely tight bass that delivers the punch that high performance home theaters command. Feel the rumble of explosions in your Hollywood blockbusters or hear the crowds roar when you score a goal in your favorite video games. Its great for music, too, like when you want to relax to the taut, tuneful lows of an upright bass from a classic jazz number. Plus, the front-mounted controls make it simple to adjust the volume and crossover frequency on-demand, so you can get the best performance in your room.Product highlights:frequency response 30-150 Hz (±3dB)built-in amplifier delivers 150 watts of continuous power, 450 watts dynamic peak powercontinuously variable low-pass 50-150 Hz crossover10 polypropylene woofer conebass-reflex (ported) enclosurefront-mounted volume and crossoverrear-mounted phase switch and auto on/offline-level/LFE inputsspeaker-level inputs/outputsblack ash finish12-5/16W x 17-3/8H x 17-1/8Dweight: 31pounds

* FOR REPAIR OR PARTS - THIS IS A NONWORKING COMPONENT * This vintage SVS BASH circuitry subwoofer amplifier worked for over 15 years before it recently stopped outputting. The filters and controls worked when the amp worked (I never used the high-level connections, so I dont know about that). The fuse is good and the status LED does still light up. If some DIYer has the knowledge to replace whatever on the circuit board thats failed, it would be a great-sounding, powerful (this amplifier cleanly drove two high-excursion 12 DVC woofers wired in series) subwoofer amplifier with built-in variable crossover and subsonic filter. Includes the original power cord as supplied by SVS. Approximate dimensions of the plate: 12 high x 8 wide Approximate depth of amplifier components (protrusion into the subwoofer cabinet): 7 Approximate weight: 5 lb, 6 oz Buyer pays $24.99 for shipping via FedEx Ground or UPS Ground (sellers choice) to physical addresses within the 48 US states (no PO boxes). Why do I charge shipping rather than do free shipping like other eBay sellers? Because for most eBay buyers, sales tax is charged on the sale price of the item... as theres no such thing as free shipping just as theres no such thing as Santa Claus, sellers who offer free shipping are just rolling their real-world shipping cost into the total sale price. A separate shipping cost means a lower item cost = lower sales tax = you pay less! https://community.ebay.com/t5/Selling/Tax-on-shipping/td-p/29270434 Local buyers are welcome to pick up in Longmont, Colorado, with no shipping cost, of course. Please take a look at all of the pictures, check my seller feedback (nearly 100% positive over 20+ years from over 500 different buyers), and buy with confidence. I package my items carefully to prevent damage in transit and they are typically shipped within one business day of confirmed payment. This nonworking/for repair or parts SVS amplifier unit is sold as-is; no returns.
