    • Great subs
Review Image by Benjamin W. Benjamin W.
Using 2 of the 15 inch 8 ohm as my home theater subs powered by a Bryson amp at 250 watts RMS a piece, crossover output from an Onkyo TX-NR676. Amazing subs! They shake the house lol. Eye opening vs a set of cheap home theater subs. Sound clarity is very good with my set up. Only complaint i have is the low signal to noise ratio. This is not an issue with my set-up since I can tune my receiver for both subwoofer volume level and independent sub EQ levels but this may become an issue with a receiver/amp that doesn't have this ability. Having to run +6db on the sub volume for proper balanced level. ... show more

    • Product as described - Church use
Excellent bass. These set of speakers worked wonderfully from the box. They are rugged and handle my amp, they improved the sound quality the minute I plugged them in. We use them in our church and thus far they been amazing.

    • Impressive deep rich bass and well made
Review Image by G. Grant G. Grant
I love the compact size. They are perfect fit for my set up. I also prefer passive speakers so I driving these using a crossover to ensure I have the right bass and a power amp. Wow! The sound is amazingly rich. The value is unbeatable. I wish I could have 4 of these but my neighbors would hate me more. ... show more

    • They do what they’re supposed to do. Carry your low frequencies
Subs work as to be expected when used with proper crossover frequency. One of the 2 subs showed up with a bent/pushed in Grill with no shipping damage on the box whatsoever. Hmmm.

    • What’s important to know....
Use the Rockville PPA-20 or PPA-50 preamp and the Rockville RPA-3000 power amp together with these or any other Rockville subwoofer and I promise you that the bass sound you get will rock the house down...!!! 👍😀
