snoopy was using 2.5 cubes tuned 43. and 1500 rms to get the 146 with on. So imagine, with 2 of these and 2000 rms, 2.5 cubic feet for each sub, you should be able to reach 146 + on tl with music. This sub is a low end monster. 2 of these would def be louder than a BTL with 2000 or even 2000+ rms. And at half the price.
I think the reason for his selling is due to his amp not running well at a certain ohm load, and it blew?. so he decided to scrap his set up. he also wasnt running alot of power to them, but we was at the 150's with four of them. I also think these would sound better than the BTL's. They are sold on
ebay new for 170 each.
After doing some research I found these to be a nice spl sub with sq. underated, Better than BTL SQ. Offcourse i never heard them, thats why i am trying to get ahold of snoop dan to see if they stand. But i will test them and write a full review when I get them.
Again, I hope this helps whomever is intrested in buying these. Again 2 of these should be louder than a BTl with better sq, if you know how to build a descent box. They are D 4's, and not many people have them.
