Posted June 29, 200718 yr I am buying 4 15's and I wanted to know which was the better choice. I understand that they both have the same RMS wattage I am going for more spl and lower bass. I wanted to know which sub would produce more bass in the lower octave. I have no problem as far as space I just wanted to know which produces more output.
June 29, 200718 yr Admin Since your first mention was SPL, I think the BL might be the choice. If you want a really loud daily driver, the Q's would be more then enough.
