    I was not expecting this sub to fill the room with as much sound as it pumps out. Not to mention when correctly equalized the low frequencies dont distort nearly as much compared to other starter subs.

    I use this sub in my living room. I like the adjustments on the unit for bass response. Only drawback is it take a little bit to kick in, but overall no big deal. Really fills out the room that was missing with my older non-active sub. Sounds great!

    For a room 12x19. It was ez to fill up with bass. Changing from the polk 8 in sub which had to be push to its limits, this easily and convincingly is an improvement for budget subs. Yes the cabinet is nothing to write home about as far as design nor even has any feet (just rubber stickies) but the rumble is undeniable.

    I've been planning to upgrade my Boston Acoustics sound system given its age and the speaker surround has totally degraded. I'm still planning on repairing it down the road (might cost me an arm and a leg) but I needed an immediate replacement and the Sony Core Series caught my eye. It's a good subwoofer at a great price point and when it went on sale for 50% off I immediately one + a pair of Core Series Dual 5" 3-Way Floorstanding Speakers. It works perfectly with my Denon AVR-S540BT Receiver, specially after calibrating. Great Bang for your Buck!

    Auto-On/Off Poor Design

    Posted . Owned for 1 month when reviewed.
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Unless I'm missing something, this unit has only the option of "off" or "auto-off." In auto-off mode, if you are watching a movie with a quiet part for too long, it will switch off, which causes an annoying on/off click. Then, when the movie calls for bass, it takes a second or two to auto-on and start pumping out the bass. There should be a way to adjust the time length of no signal or some other way to keep it on while it is possible that it will be sent a bass signal. When it is on and working, for the price it sounds very good.

    No, I would not recommend this to a friend

      Hi jasoncg1, thank you for your feedback. We are really sorry if the auto power-off function did not live up to your standards. If there is no signal input for a few minutes, the POWER indicator lights up in red and the subwoofer enters power-saving mode. We will surely take note of your input as we always strive for the best customer experience.

      Despite the issue, we are glad you like the amazing bass sound quality of this subwoofer. You’re going to love the room-filling sound that Mica-Reinforced drivers can deliver. You’ll experience deeper, more precise bass reproduction than ever before and be amazed as your music and movies come alive!

    Our subwoofer went out quite a while ago and I got this for my husband. We don't have a media room so this was perfect for our living room. Not too thunderous but puts the sound out when needed.

    Very cheap subwoofer but definitely gets the job done for a beginner. The only downside is that it doesn't turn off when the rest of my devices do (non-CEC compatible) and it doesn't have a remote (do any subwoofers have remotes?). Eitherway, for the price, definitely a great subwoofer.
