I modeled the sub beofre I built it. If you meant measure, no I haven't gotten around to it. The sub is a fine performer for small rooms and apartments. The SPL numbers I posted on it were from 1 meter with the sub in a corner. There was definitely a lot of room gain going on in that specific room.
I didn't want to open another threat with almost the same name
I would like to buy one of SDX 15" but, didn't get any respons from CSS about the total shipping cost and if they could send it in Europe (Romania), I hope i can get an answer here.
