i am not gonna buy a new sub, but i just did a small research just for fun... and came up with ACI Titan II LE. how does it compare to hsu vtf3? i also read articles from CES Las Vegas, and well, i was surprised that there are still tons of obscure brands that i havent heard before. NSM? Soliloquy??? anyway, i am interested with the ACI sub. it looks beautiful.
