Yes. What is this mystery sub?\n\nHonestly I haven't nailed down anything yet. I'm still wondering if it might be better to just save up for 1 15in sub and see how it sounds or instead look at 2 smaller ones and pursue a dual setup. So many options I guess. The room isn't an ideal setup either. Also, I can't place the sub(s) at the front facing the listening position. I have a good spot for one so maybe it might be better to just go that route and get the best sub I can afford.
