Boon Posted January 26, 2009 Report Share Posted January 26, 2009 I don't think you have the room to build a horn for 2 18's. Pete from PWK Designs had a rear-loaded horn for his 2 15's and that was a full wall. If you want to get NEAR 156dB your only option is a wall really. You could possibly do ok-ish numbers with a box like David's old Mustang box but it will still only be low 150's. Quote 10.x volts fo' life!

Boon Posted January 26, 2009 Report Share Posted January 26, 2009 Ohh. If I did have enough room for a horn how much db you think I could pull then??? Who knows. Horns are usually made for high efficiency over a large bandwidth. Probably still into the 150's but it's pointless to consider, a bass horn for 18's would be ENORMOUS. Out of interest, have you ever even competed before? You're talking about a HUGE system and I have a sneaky feeling you don't really have the basic knowledge required for a project like this...

Neo_frog Posted January 26, 2009 Report Share Posted January 26, 2009 Goal:156.4db-158.7db Why did you pick such precise numbers? Maybe if you had four huge 15s using every last bit of space tuned properly on 20k+ watts, you'll hit your goal on a burp, but otherwise good luck. Be prepared to spend big money.

jizzybizzy Posted January 26, 2009 Report Share Posted January 26, 2009 this seems like a huge project. 156 is like 4x louder than 150 or some shit (what is it.. for every 3db its twice as loud?) make sure to take lots of pictures and vids Quote you ain't been bizzy til you've been wit jizzy.
