Thanks for the recommendations, guys... F2's, huh? Nice! Unfortunately, price is a factor. How do you suggest I try to properly size the subs? Let's say I want to stay under $1,500 for the pair... would moving up to the Sunfire SDS-12 be enough of an upgrade? From a spec/performance perspective, would a pair of these subs be sufficient? I understand you guys like the other brands, I'm only trying to get a sense of scale (e.g. the SDS-10 v SDS-12 in my space).
As for the power... I wish I could be more specific in defining poor power beyond inconsistent power (spikes and brown-outs). My reasons for this equipment was to protect equipment and improve sound. Perhaps I'm making a something out of nothing. I appreciate the questions, I will spend time looking at these line items closer.
