Q: Does this subwoofer include an integrated amplifier?

A: No, this subwoofer does not have an integrated amplifier.

Q: Does this Sony subwoofer have a high sensitivity?

A: Yes, the Sony subwoofer has a sensitivity of 84dB.

Q: I bought this sub to connect to a Sony STR DH-590 Receiver but I’m getting no bass sound? Don’t know what I have connected wrong?

A: Check the wiring running to all your other speakers and ensure all the other speakers are playing. If the other speakers are working fine, then check the line running from your receiver to the bass. I am using an Insignia 15' Subwoofer cable to connect my receiver to my Core Series 10" bass. Check to make sure you have a solid connection. After checking all wires and speakers for connectivity, make sure you turn the bass itself on. The Sony Core Series 10" has its own power switch located on the back of the speaker near the bottom (its a push button switch). You'll know its on when you see a green light appear on top of the bass near the rear next to the vents. If you have the receiver connected correctly to the bass, AND you have the power switch on the bass pressed in and you see NO light on top of the bass, you have a power problem with the bass and you will need to get it fixed or turn it back in. If you have everything connected correctly, you DO have the power switch on the back of the bass pressed, and you DO see a green light on top of the bass but still have NO sound, you have a blown speaker in that subwoofer.

    Sony, oh Sony, you rule my ears!

    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

    Boom

    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.

    Why spend more? Great Subwoofer

    This thing is great! I was about to spend triple on a klipsch but so glad i didnt. Great, clear, room-filling sound from this. And if i want to make it obnoxiously loud i can add a second one of these and still be cheaper than a single klipsch. What a value! Paired with STR-DH790 receiver (love it, great value) and Klipsch HT-50 center and satellite speakers (love em). I plan to add Sony towers.
