The Vortex is based on the highly successful Epicentrix and has been designed to deliver perfect timbral matching to the Harmonix main speakers. This same tweeter is also used in the Phoenix and Apex floorstanders meaning the Vortex can also be used with a wide range of Krix products. The dual 165mm bass drivers, single midrange and 28mm tweeter used in the Vortex are identical to those in the Harmonix ensuring the ‘audio stage’ is seamless in it’s transition from left to right. Focus is on vocal clarity, midrange depth and a dynamic bass response. Experience the sonic strength the Vortex will bring to your home theatre system.
So I set the Vortex to ‘Large’ with my home theatre receiver to ensure it received all the bass, spun up the disc, advanced the volume control to a ridiculous level, and waited to see what would happen… and what happened was that the Vortex delivered a musical performance with tightly controlled and remarkably deep bass. Not as deep as if I’d set it up properly (I would suggest setting a crossover of 50Hz for the truly deep bass to go to a subwoofer that can reproduce it with greater impact), but it coped wonderfully. That is indeed impressive.
