Thanks very much to all of the bassheads! Great info pretty much in sync with what I've been researching. A bunch of good suggestions. Seems like the consensus is 2 subs for my size room - makes sense. Always wanted to hear Audiokinesis' stuff. Unfortunately way out of my budget at this time. Basically, I have around $1500 to blow. Was thinking a sub and DAC (see other thread in digital). Really need to get up to speed with digital. So, its a balancing act. I started out thinking better sub and an inexpensive DAC like a Dragonfly. Now I'm leaning towards spending a bit more on a good dac/streamer.
As far as the subs go, there are two local on CL that seem promising - a HSU vtf-3 mk-4 and a SVS pc-2000. Any opinions there? Really just want to experiment and start with one before jumping into 2 subs and a high pass filter (pretty sure I will get there eventually!). I have had good luck with used in the past and it has given me good bang for my buck.
Thanks again
