Do some searches on the forums. You'll see that ACI subs are extremely well regarded and have often been preferred to the more expensive RELs. My observation is that the ONLY reason we don't see the ACI name more often is that they don't advertise. So, with the others, we get to pay for their advertising. A wonderful company to do business with as well. A pair of Force with Maggies would be amazing for less money than a single Storm III.
