VISONIK 12D

The following review is for a previous version (V12D4).

I have been working with car audio for years and have a stereo in most of my cars... These subs aren't no MTX thunder 9500 or a JL Audio W7, but with the right box and amp, these subs sound amazing. Currently i have a dual 10" wavebox built powered by a JL 300/2 and these things sound AMAZING!!!!!!!!!! they are a good starter sub.. dont let people tell you otherwise, its the box that counts!

:o

I've run this sub for about a year now, on 3 different amps and a few different deck setups - it's rated at 300 rms and I've put 600-800 for hours on end and it doesn't skip a beat. With every other sub I've run off my system, none sound near as good as this.. Fantastic value for money and if you want something that deals with abuse and comes back for more .. consider Visonik.

The following review is for a previous version (V12D4).

This sub i wouldnt recommend to anyone that is thinking of upgrading there systems. I bought this sub in a store in my town for $60 canadian(no warranty either). There are better subs that are around for about the same price with better sound quality and a harder hit. For a 12" sub i was dissapointed no good with the lows. But if you like the sub good luck trying to find it any cheaper than here/and an authorized dealer.
