DC Sound Lab

My Dc L4 15"s At Iasca - 151.6db


Recommended Posts

Hi guys, i'm new to the forum and i'm from Trinidad in the West Indies..

I just recently bought a pair of Level 4 subs and have to say they are great performers! Some real low frequency monsters..

I'm mainly using them for IASCA SPL competitions powered by a pair of Sundown Audio SAZ1500Ds

i lowered the tuning freq to about 40Hz (net volume dropped to 4.1cu.ft) and just hit a 151.6 on the Audio Control meter this evening..

i believe another 0.5dB is possible with these boxes..

question, what's the best score you guys have seen made with around ~3200Wrms.. my personal goal is 152dB but i not sure if that is high or low for my power..
