Update to old post on which subs to get.
Finally got the balls/cash to get what I think is in my mind as an excellent setup, very tight/fast/deep bass. Just purchased 2- Rythmik F15HP subs, these things are awesome, they integrated very well with my Tyler Acoustic Linbrook sigs. Lucky me my Classe CP-35 pre had one set of balanced outputs(hooked up to ARC amp) and 2 sets of unbalance outputs, currently have these running to each sub. Can`t thank Brian at Rythmik enough for a great product. I included an updated pic in my system profile. I am in bass heaven if there is such a place.
