The guidelines offered by Sumiko are excellent for subwoofer placement and setup. If you follow their recommednation you should be able to get deep, non-boomy bass. Of course it is possible that you room is such that corner placement is not the optimal setup, but it's unlikely. Remember, it can takes weeks of experimentation to properly setup your subwoofer.
why go against REL setup recommendation?
My new REL storm III will be here next week. I've been following the posting on this sub for quite some time. I'm curious as to why the general consensus is to ignore REL and Sumiko's recommendation regarding corner speaker placement and the non use of spikes. Is it possible in all their infinite wisdom they don't know what they are talking about.
