This is an awesome forum! Thx so much for all the great feedback. Based on everything I've read here, my current plan is...
First, recruit my neighbor to help me position my existing Descent i and do the sub crawl...
Second, place my Descent i at the appropriate location, and run high level connections to it off my mono blocks (I'm currently only running the LFE channel off my AVP)...
Third, I'm going to run this for awhile just to get used to things since I've never had a sub on my LR channels before...
Finally, if I like what I am hearing, I'll go ahead with what was my planned upgrade to a BF 212... and 'possibly' to a pair of BF 212's...
Frankly, I'm probably trying to do too much at once but I am trying to plan out my steps to avoid as many mistakes as possible. I am still dealing with final positioning of my ESL 15A's... and since I have a significant birthday upcoming, I have an Illusion C34A on the way (happy birthday to ME!). Once I get those two dialed in, I think that is really the time to get serious about my 'sub project'...
Sound like a plan?
