Review on 🔊 Polk Audio PSW111 8" Powered Subwoofer with Power Port Technology - Up to 300W Amp, Compact Size with Big Bass - Easy Setup for Home Theater Systems in Black by Nick Bigalow

The subwoofer worked perfectly for the first 5 years. I will confess to being a fan of Polk products in general (I have many different product lines) and unfortunately this is the only one that has really let me down. This is a great subwoofer for a small room (up to 2000 CFT I'd say) and delivers a surprising amount of bass for its size and price (less than $200 off of course). Most recently the sub stopped working due to a broken bass amp - part number RF1145-2. I've read on other forums that this is a common problem with some Polk subwoofers. You know it's dead when it starts making a heartbeat, even if there's no music playing through it. Since the warranty is only 3 years, I have to buy a new subwoofer or pay $140 to replace the amp. While I wish it lasted longer I'm just using this as an opportunity to update and explore other brands like SVS, DefTech, HSU Research and so on.
