None of my avrs has a bass peak limiter, first I've heard of one, too. There's the (Denon?) Low Frequency Containment feature on some avrs, but think that's more than just a peak limiter.
Caution would certainly be key, but not sure if the OP's listening levels are going to be a concern even running the speakers full range (which is why I'd start there and work my way up). I've not gone without a sub either, tho.
