Also has anyone tried doing their own version of sandbaggers turbo with say Dayton Audio RSS390HO-4 15" Reference HO and an external amp?
$100 for both is a pretty good deal.
The HO does pretty well with the same to little more power but if your gonna feed it like 1000W IMO a better driver would benefit you. From memory the HO gets pretty close to x-max with 500W in ~3.0ft^3 tuned to ~19Hz(approx specs of MFW15).
I can't model on this PC but I like the Behringer DSP amps for what they are and one channel of the NU3000DSP with the 15HO in that cab should be a good pair if the HO works ok on 620WRMS. That leaves the other channel to run your original. You could recoup some of the cost by selling the original drivers. So really not that much money for a big upgrade.
Get someone to model the HO in the MFW enclosure and see how much power it will take, I can't remember exactly. Assuming it works well on 620WRMS.......
Buy additional Cabinet $100.00
Sell two original drivers ~$80 each for +$160
2Dayton HO15s 2X $149= $300-$160(from original drivers)= $140
Behringer NU3000DSP= $350
Total= (100)+(140)+(350)= $590
I'd ask MCCA about output comparos but two subs should have a smoother response capability over one especially since the Behringer has PEQ.
