I had purchased a 5.2 surround sound system. I only purchased 1 subwoofer when I installed the system. I felt like it could be improved with the addition of a second subwoofer. The addition of the second subwoofer seems to give the system a fuller richer sound. I am very satisfied with this addition.

I purchased this subwoofer with out a doubt that it would perform.

Since the Sony Walkman, 1998 component receiver, Mege Bass days as a kid I fell completely in love with Sony. They know they type of bass I like to hear. Not too punchy but also very much present. That has not changed today over 20 years later. Here I am thinking I can just use 5 speakers without a sub on my Yamaha receiver. The Sony floor standing speakers definitely performs well without a sub but God oh mighty is it like heaven with this Sony sub! With a room correction mic all my speakers put out the bass they need to and it sends the most beautiful signal to this Sony sub. With bass enhancement on and cross over set to 40 HZ on my Yamaha receiver emphasizes the deep lows at ALL volumes and this Sub takes full advantage of that. It seems to know the expected output of this sub so that clipping is not an issue.
I can imagine running an old school amp with speaker line in may not be as good. Since you only have the crossover on the subwoofer and whatever frequency the receiver puts out by default on speaker level. Not a deal breaker because I never intend on using this sub that way. You have more control over the sound on a separate subwoofer line out.
Biggest complaint… It does shut off quite fast (3 minutes maybe) when watching movies with at night with little to no bass. So when bass does come you will miss about 1.5 seconds of the bass before the sub turns back on. You do have the option to turn that off on the sub but I keep it on. Saves on electricity and my sound is very balanced so It does not bother me as much. I can make corrections so that it stays on but I like deep lows to get out of control so I keep the crossover on the sub to the lowest while the gain is at the highest. This thing has me wondering why I ever went to the movie theater to begin with.
Seriously the best thing I could of bought working from home.
I didn’t catch it when it was 99.99 but at 140.00 I still don’t feel robbed! If you got the money, BUY THIS THING!
BTW Sony, if you had the 7.2 receiver I originally wanted in stores I wouldn’t have this Yamaha receiver! lol

I have a Sony Stereo Receiver (STR-DH190) with Sony SCS-CS5 speakers that give a clean, detailed sound. This Subwoofer adds low end depth and punch that enriches the sound of music and TV audio.

Hooked this up to my Sony STR-DH190 stereo receiver along with a pair of Polk T50 speakers. Connected using the speaker level inputs (my receiver doesn’t have a dedicated sub output). What a difference. Prior to this sub, some of my older vinyl records just sounded flat on the Polk T50’s. This bad boy has brought new life to those records. Depending on how you adjust the sub (knobs on the back), turn it up and you will feel the bass. Booming bass, deep bass, tight bass, room shaking bass – this sub does it all.
