15" subs for DJing

robotnation · 26th June 2007, 06:01 PM

i havent been on this forum in a while, but i was curious- can any of you suggest a 15" driver to use for bass as well as kick when i DJ? most people suggest 18" for boom and 15" for kick, but i want something that can do both by sacrificing a little of the outrageulsy low basses and kicks for a flat line from 50-190hz with an efficiency of say98-99db. lots of people say down to 40hz sounds good, but i will only be doing techno and house, not d&B or anything like that. I only have room in my house for two subs at the moment, so i think its important that i get a bit of quality as well as a moderate quantity of sound. What i was hoping for is a BL low enough for me to get a flat response even down low, a moderateley high efficiency, and an FS not too low but not too high either. Wattage and Xmax are nice to have but honestly i have no clue if ill find amps to run a good speaker full blast (400 per channel at 8 ohm, 700 at 4 ohm, 1400 at 8Ohm bridged, 2400 at 4 ohm bridged with the amp i have atm...)

so What do you guys have in mind? i been at aloss since i modeled everything already and cant get it to go below 60 without loosing a lot of quality or volume, so any advice would be greatly apreciated! -matt-

oh one last thing- im hoping to keep the box less than 4.5 cu ft, and also i was planning on going rephlex...

These are nice if you are at all concerned with moisture. I have six of them.

Here's what they look like for real.

I'd think there oculd be a "bit" of kick with one of these -(anyone agree?)

Greets!

Good luck with that, you're going to need ~8.829 ft^3 for this much efficiency to 50 Hz.

well i did it with a 6 cubic foot housing, flat from 52 up to 200hz... it gets 98 db efficiency on that spectrum (give or take 0.5db; give or take 1.5 db on up to 440hz =o) check this stuff out.... http://www.usspeaker.com/beyma%20sm115n-1.htm its just an all around good speaker for the price, low BL and decent efficiency. Im in the middle of a college class not listening to a thing thats goin on. Ill post the spl curve when i get home in an hour. Some speakers have a good flat curve until you get to full blast when it gets notches and spikes- this one doesnt do that. Should be some bumpety bump techno goin down soon ;]
