Thanks. I have found that if anything has too many adjustments I have a hard time getting it dialed in. I am close to buying Subs now...a hard decision for me. I have mentioned our rambunctious hairy Jack Russell Terriers before. For this reason, SVS Subs are still in the equation due to their metal grills.
I have had several servo subs, and realize the advantages.

Our new home is behind schedule, and this has given me several months to decide. I am to the point where my brain is frozen.
