Blackstar Unity Elite 700 through an Ampeg SVT 810e

[UnhallowedSam]

I just got an Ampeg SVT 810e for some larger shows I will be playing, and need to find a good head to push it. I really like the options of the Blackstar Unity Elite 700, but it operates at 2.67 ohms. Would it be lower wattage at 4 ohms? If you have played this setup, what was your impression?

2.67 ohms is the minimum load that the amp will safely operate with. You can use it with cabinets of 4 or 8 ohms as well. It will have no problem pushing an 810.
See page 12 of the owner's manual for details on how much power is delivered with different loads.

Wattage is a pretty loose metric. 8x10' speakers will shake your soul no doubt. I've never played em, but they sound like a capable duo to me

By the mains input it says "850 Watts". Assuming the maximum sustained power draw is half that (425W), I would say the 700W rating at 2.67ohms - probably something like 500W at 4ohms - is pretty darn conservative, compared to some of their competitors. So, yeah, the U700 should have plenty of juice to drive an 8x10.

The U700 is 500w at 4 ohms and 250w at 8 ohms
