Ultimate 745

The Ultimate-745 not only incorporates Sound Lab's latest electrostatic panel and electronic technologies, it also incorporates a massive steel frame to protect and preserve the critical tolerances of the electrostatic panel. The heavy duty frame employs three-inch diameter steel support posts that are solidly connected together with 1/2" thick steel brackets, terminating at floor level with spikes for solid floor coupling. The high reactive mass of the framework eliminates frame vibrations, thus eliminating frame resonance and insuring that all sonic energy is converted to music.  Further, the Ultimate-745 includes Bass-Focus technology that increases bass dynamics by more than 6dB.

The massive steel frame of the U-745 not only provides technical benefits, but it also manifests a unique space-age beauty. A wide range of finishes and grille fabrics are available.

Ultimate 545

The Ultimate 545 is our answer for those who desire "Ultimate" sound but do not have the room for the larger Ultimate models. The Ultimate 545 is scaled down in size but not in performance, having exactly the same electronics as the larger models and employing the identical internal panel structural philosophy. The radiating area of the Ultimate 545 may be smaller, however the panels incorporate Bass-Focus® technology, bringing the bass performance very close to that of the larger models.

The space-age appearance of the U-545 along with the sturdy steelframework provide timeless beauty and superb sound.Black micro-texture Polane finish and black double-knit fabric are standard, however a wide range of finishes and grille fabrics are optionally available
