Hi. I just audition 2 subs. A Klipsch RW-12 and a Boston Pw-900. I prefer the sound of the Boston but my room is wooden floor on a second floor so I a little afraid of too much shaking and vibration(the boston is downfiring), and of course there is SVS. I can’t audition the svs , I not live in USA but I have the opportunity that a relative can bring the svs to my country (Costa Rica) So any recommendation of the perform of these subwoofers against a PB12-NSD or maybe the new SB12-Plus for a room 26x15x10 .My current subwoofer is a Yamaha YST-SW300 12 inch driver with 175watts rms. The price will be about the same between the 3. Thanks
