definitally agreed, and from my point of view if you cannot provide parameters to me it seems like your hiding something... hence steer clear of DD althought i know there really good drivers if I had never used them i would never buy them... they don't provide any imformation besides QmS QES FS VAS... that a poor list of parameters... and simply put if i am going to drop 2k on a system i want to see what aligments i can use and if they meet my standerds/expetations... anyways i like the woofer they look excellent and i respect you because the price is resonable... i also know how hard it is to get respect/credibitily... so by all means do ya thing...
