Great sound

The following review is for Reference 1270, which is a part of the bundle you are viewing.

All in all it's a great beginning subwoofer for the mild bass lovers. It will handle it's rated plus 75 watts more. It doesn't take a big amp or even a expensive amp to run a pair of these hard. Coming from a person that's a old school bass head I have a pair of them on a old school punch 75hd and they sound amazing. 2cube per sub ported at 32hz in a Mitsubishi outlander.
