    • good sound for low cost
Style: 8” K6 Series 2 Ohm
I had a Planet Audio sub in a small sealed box that I also bought on Amazon. I replaced it with this one and was worried that the airspace would be too small for this. I was really impressed at how much low bass this put out even in a small sealed box. I am considering making a larger enclosure. I am running 250 watts RMS to this sub. I don't think you could beat this for the money. I paid $45 for it. Very impressed. ... show more

1st time purchase from Rockville Audio. As a resale item quality of materials remains functional and performance is acceptable if new. Cosmetically no visible sign of damage. Item price is selling point. Dual voice coils for more power handling and ease of set up. Dust cap, cone and speaker surround look and durable. Magnet size and fitment of speaker is good. ... show more

    • Good stuff
Style: 8” K6 Series 4 Ohm
Compliance curve is sweet. Excursion is good. Fit and finish is excellent. Needs break in. QTS is off. I'm finding a lot of woofers with QTS in the .9 range like this one. Fs is right on. Times have changed and you've just got to tune lower than fs, lose efficiency and roll with it for sq. Or tune high for output. Or go sealed because it's under damped. This is all a byproduct of stronger suspensions in modern subwoofers. This is to protect it from high power and low frequency over excursion. Pretty flexible. Good value. ... show more

I needed 1ea, DVC 4ohm wired to 8ohm for less power draw so I don't need a farad. Works perfectly & can't tell it's running at 8ohm. Perfect for my application

    • Budget sub with great sound!
Style: 8” K6 Series 2 Ohm
I installed this 8 inch DVC sub in a sealed box with about 0.4 cubic feet volume. This little sub packs quite a punch. For my needs, this is enough bass. The sound is great. Highly recommended.
