Dayton DC300 equivalent

audiothings · 23rd April 2011, 12:54 PM

I have built AK's econowave using Dayton DC300s in huge 170L cabs (tuned to the early 20s and crossed over @ 1.6 KHz). The sound is fantastic and lifelike, but the two woofers sound quite different from each other... one suffers from a serious mechanical resonance @ around 80 Hz and the other has a less bothersome resonance elsewhere... also is the magnet a bit anemic? I wonder if it struggles at high volumes, or its the random amp I've paired it with. Regardless, its terrific at any reasonable volume, save for the inconsistencies and resonance.

I have tried modeling the following speakers in WinISD and none of them gets close to the DC300 in terms of LF linearity:

Vifa NE315-W
AE TD 12H
SB Acoustics SB34NRX75

So I am looking for a 12" woofer which is fairly linear between 25 Hz and 1.6 KHz in a 170 Liter vented cabinet. I am willing to redo my baffle if necessary.

Thanks,

Thanks.

Turns out I had entered the "vas" wrong in some of the drivers referenced in my last post... the SB Acoustics driver referenced above shows great promise... -3 dB point is @ about 22 Hz! Would it be a suitable drop in replacement?
