Sorry that I missed responding.
1. The original Doubler had a power rating of 250 into 8 and 450 into 4.
2. EA decided to not push the Ice module as hard as other manufacturers ( a good thing). So--other manufacturer's amps using the same module go a bit louder, but with higher distortion.
I also felt that the original didn't have enough "oomph" and was not a good match for electric. You see, most of the high-end (sonically) speakers out ther (mine included) are not as efficient as cheapo cabs. So--contemporary cabs need more juice. As a speaker designer you pick your compromises---if you want great low end performance and high xmax (excursion) the compromise is a less efficient cab.Most of the commercially available speakers for electric bass don't have good extension nor excursion, A cab with 3db higher SPL will require half of the wattage. Because watts are relatively cheap these days, most higher end speaker designers take advantage of this.
I had an ICE 250axl2 module laying around. 500 into 8 and around 800 into 4. Same one as used in the GK's, Puma 900, Demeters, and others. I had to drill different holes to mount it but all of the connectors are the same. Took less than an hour.Tried it against the Demeter Lunchbox amp.( I love that amp) The Demeter went louder but was more distorted as it surpassed the Doubler with the new board. I don't feel that the 250axl2 is the most hifi of the Ice modules but it slams like crazy.
It now sounds great with both upright and electric. I haven't played an electric gig that it didn't cut it.
I'm really glad that they upped the wattage. Wonder which module they're using?
