daimond audio is one of the best in quality

i have an older model of this sub hooked up in my car, its louder than some of the two 12's ive heard and im not talking about cheap flea market quality, im talking about punch subwoofers and especially louder than the jl audio w1's subwoofers. Its not about the watts or the size of the magnet its about quality and diamond audio is qaulity. now with this newer d3 model i can just imagine the amount of power it puts out.

Great sub

I had one these a while ago before selling it to my cousin. I wanted a single sub setup but i couldnt run a 1ohm load with my amp, but at the time i was running 200watts rms@4ohms and this thing still pounded and it had such great crisp tight hitting bass. This sub with the proper power has to be loud. Diamond audio is a great company and gives you great quality products. This sub is prolly your best bang for your buck.

Great SQ

This sub is not only loud but it is REAL good SQ.... don’t settle for other cheap subs you will be disappointed… although they may say they have more watts then this they really don’t sound like they do. This product was 100% worth the money. This sub gets louder than 2 subs and you can actually decipher the words! Diamond audio all the way!
