Just an update to close this thread out.
I met Carl yesterday to pick up the sub. We had great time chatting up equipment, vinyl and audio stuff for about an hour.
Set the sub up last night and with some help from my friend, Dan, had it tuned and dialed in after an hour or so of tweaking.
It is the perfect compliment to my 2-ch system, rounding out the overall frequency range with a V natural texture and filling the low end with crisp, tight detail in a way my two-way mains were never meant to. I couldn’t be happier, and best of all, The wife hasn’t even noticed it.
Thanks Carl. I hope we can get together again soon!
Bill
