Rythmik Audio’s subwoofers have long had a reputation for superlative sound quality, thanks largely to their use of the Direct Servo feedback technology. In Rythmik’s servo system, the amplifier uses a feedback loop to reposition the cone if it is found to be out of place, and the cone position is always being monitored. Unless it can be had on sale for $2K or less I'd go with the Rythmik all day. At $2500 list it's just too high compared to other subs like the Rythmik, JTR 2400 or PSA V(VT3600). This Monolith THX Ultra Certified subwoofer sets the standard for bass output, low distortion, and affordability. Norges største testdatabase for gadgets, teknikk og hjemmeunderholdning!
