Ok so, I am putting a stereo system together for my bedroom, from the equipment which I replaced in my recent theater upgrade bug. I have a pair of Polk Audio RTi12's, an older Harman Kardon stereo processor, a Rotel stereo amp, but I am lacking a subwoofer. I listen to everything from Jazz to Rap, and everything in between. However, if I'm listening to a song with good bass below ~85Hz, I like it to have some kick. The RTi12's are rated down to 18Hz, but even after trying them bi-amped below 90-80Hz, the three 7" woofers just lack the kick I'm looking for. After spending a fortune on my last sub I'm limited this one to the $600-$750 price range. I had recently heard an SVS, and was so convinced by its performance, that I definitely want to try one for this system. So to finally spit my actual question, between the SVS PB12-NSD, 20-39 PCi, and 16-46 PCi, which would be the best for music and kick? Keeping in mind I have a decent amound of music that I like to crank with bass in the low 20Hz's/high 10Hz's. Any advisement would be greatly appreciated. Thank you for your kindness and courtesy.
