Sub Upgrade Build Dayton Audio UM18-22 18" x 2 LLT
So I'm going to start finishing my basement here pretty soon and, as I currently have an IB sub that is using the bass-ment for its backend, I need/want to re-do the sub first. I'm wanting to go with a ported design, tune to the 15hz range. I'm currently using 4 x Dayton Audio DCS450-4s and since they have a pretty high Fs (24.9hz) and low xmax (8.25mm), I'm thinking of upgrading to two Dayton Audio UM18-22 18inchers. They come in at 19.51Hz and 22mm. If I go for about 12.5ft^3, I can tune to 15hz, apparently (I'm just going off their spec sheet for that, haven't plotted it yet.)
I have a crown XLS602 that I've been wanting to upgrade for a while and since it only does 600W at 4 ohms (the newer Daytons are dual 2 ohm voice coiled and rated at 1000w rms 2000w peak), I'm thinking an upgrade is needed. I was thinking the NU6000DSP... but is there some sort of middle ground amp? the 3000DSP does 2 x 880 at 4 ohm and the 6000DSP does 2 x 3000 at 4 ohm. Kinda seems like overkill, but, as it's not even close to twice the price of the 3000, I guess it's kind of a steal. But would I need to upgrade my outlet for that sucker? lol
Anyhoo, advice is welcomed.
