Worth the money.
Size: 10" Set name: Single K5 Series 4 Ohm
Better than expected. Wanted to add a little bass. This little thing gave more than I thought it could or would. Honestly nothing bad to say. Its built well. Solid. Looks nice. Absolutely performs as it says if not better. Even the push hook ups for the wiring is decent, holds well even when the speaker was sliding around a bit before I mounted it. Good job Rockville. ... show more

better than expected.
Size: 12" Set name: Single K5 Series 4 Ohm
OK bought the 4ohm as a test speaker and now love it. I had a kicker 400W amp paired with a 2ohm kicker box. Speaker was very loud on bass type music. Really 2 loud. On non-base music the 2ohm just seem lacking and very punchy. Figured I'd buy this one as the box itself is worth 100$. wow this speaker is nice. after testing was going to replace it with some name-brand 4ohm but now it sounds so good I'm just going to keep it. I'll keep my 2ohm Kicker as a backup. Old: kicker 2ohm @ 300W RMS New Rockville 4ohm @ 150W RMS we will see if she last. I did spend an extra 10$ on Amazon 2yr warranty. ... show more

Rockville 8inch sub kick in a Polaris EV UTV under the drivers seat
Size: 8" Set name: Single K5 Series 4 Ohm
I wanted a compact 8inch sub to mount under the seat of my Polaris EV UTV where 4 lead acid batteries once were mounted. The sub is matched up with a pair of coax 3.5 inch Cobalt CB35s in the UTV's dash andis powered by a surprisingly inexpensive but powerful 2.1 bluetooth amp, rated at 2x50 + 1x100 at 24 volt, but which (really more like 2x15 + 1x40 at 14volts). Regardless, this sub just rocks! I was really pleasantly surprised at how well it matched up with the other components and goes louder than I ever need even at a small party with the UTV. Highly recommend this compact sub for modest power systems. Well done Rockville :-) ... show more

Not bad not great
Size: 12" Set name: Single K5 Series 4 Ohm
Decent build and sound. Found out later i want more rms and volume. If you're looking for average sound like a factor installed system you'd be ok with it. I wanted deeper lows so returned.

You should absolutely never buy used items from this company.

You should absolutely never buy used items from this company. It’s nothing but a headache. It isn't actually cheap; the mental stress and wasted time make it far more costly.

IM SO Happy I purchased this subwoofer and at a great price! The sound quality is great and the subwoofer functions as it should! Definitely recommend buying the Amp that rockville SELLS as well but even with any amp the quality of this is amazing!

Excellent box and woofer!
Size: 12" Set name: Single K5 Series 4 Ohm
Very impressive bass for a 12" woofer. Comparable to the old punch 15's from the 90's. I basically stole it on sale for $99 bucks. Worth every penny and more. perfect size for my little truck too.
