If you are looking for just more midbass get dual PSA V118 subs. If you want more output and extension look into JTR.
The Klipsch subs are actually pretty potent above 40hz and don't often get the credit they deserve.
First of all, thank you everyone for your input.
Just a quick note I wasn't basing this one the bad experience at all. I am very familiar with SVS and their amazing rep. It was more so about the output and over all performance.
I have a 150" screen and the PB 4000 would be the max size I could use since I have about 25" from the ground to the bottom of the screen, so a bit limited.
When I got the dual 15's (I wanted to have more than I need, since having so much more headroom would play very smoothly at lower volumes) I was having super high expectations. Chest thumping tactile hit. The Klipsch R-112Sw behind me exactky 6' has a far more tactile hit that I can feel and shakes the couch. Yes I know a lot of it has to do with it being near field, however two 15's being 17' from me should be just about the same if not WAY more
Don't get me wrong, I do feel them, but not what I was expecting by going with 3 subs. My speakers are set to 80hz. Always have Dolby ATMOS bitstream set for Blu Rays.
Thinking just turning the subs up to %80 and the Denon another +5db
Coasters wouldn't work for me as I have mine on custom spikes since I am on carpet. I did notice a HUGE improvement when I spiked all of my subs. Mostly tighter and smoother bass.
My 15's are 400 watts rms/800max where as the SVS PB 4000 is 1200rms with 4000watts peak.
Of coarse numbers do not always mean its going to be louder, as there's always other variables involved i.e. Room dimensions, type of surface, placement, open walls or doors, etc. However with that being said, 3 times the power, one would assume there should be quite a drastic difference?
I am not looking for a big difference spending almost 3.5K, but a Jurassic Park kind of difference.
