I just got the latest Home Theater Magazine yesterday. They reviewed some high-end systems from Parasound Halo, McIntosh, and, hmmm..........well, Polk. At first glance, the ($4K/pr MSRP) Polk LSIM707's drivers reminded me of the DefTech Mythos, but the cabinet reminded me of my Salon2. The size of the Polk: 9.5" x 50.9" x 18.4"/ 99lbs. This I gotta see. So I went straight to the FR measurements, thinking I would get a good laugh. I thought I would see something like +/- 4dB or 5dB. But, no. I was shocked. Here is the 5-point average FR of the LSIM707: +1.05/-1.73 dB from 40Hz - 20kHz! The F3 = 34Hz. As comparison, here are some much more expensive towers from 200Hz-10kHz (+/- dB/ F3): Focal 1028Be: 1.75/1.84/48Hz Salon2: 0.99/2.25/25Hz Paradigm S8: 0.97/1.90/51Hz PSB Synchrony 1: 1.18/2.24/56Hz Thiel CS3.7: 0.98/1.24/37Hz Polk: 1.05/1.73/34Hz The Polk measures just as well or even better than some.
