Mazdawgs /proffessa's New Build


Recommended Posts

Would you mind sharing the knowledge of getting 50+ at 30hz and lower?

I have been boggling my mind over this ever since I saw the 4 12" Directed's do 150.3 at 23hz.

Does it have to do with port length?

Quarter Wave?

I love chopped and screwed music and most of that style hits in that range and I want to show people how low a 12" can get.

dude that was 4 10"s! jamesy's cab in his pug i did is a BR loaded transmission line. roughly it has a shorter line length than a normal TL for each 10" with a restricted vent at half the length of the line. this allows reinforcement of notes much longer than the line. we moved the tuning up a bit the other day so now she peaks in the low 30's. she gained 0.2 db and also sounds alot more musical. before she wouldn't cleanly push much more than 47hz before sounding muddy if u know what i mean. now she goes to 50 with no problems. damn flat still goes to 20hz @ 145+.
