Anyone heard SP Technology loudspeakers?...


SP Technology manufactures two speaker designs, the Timepiece 2.0 (monitor) and the Continuum A.D., which is a large three speaker "monitor". Enjoy the Music featured a glowing review of the Timepiece 2.0 (http://www.enjoythemusic.com/magazine/equipment/1003/sptechnology.htm)

SP Technology encorporates an interesting driver design called "Waveguide Technology". This is described by SP Technology in the following way:

ACOUSTIC WAVEGUIDE TECHNOLOGY
Waveguides are similar to horns in that they change the air load that the driver "sees". The difference lies in the extremes. Our waveguides are characterized by the fact that they utilize relatively low compression ratios. At higher frequencies the air load is virtually the same as a standard "baffle" mounted driver. This eliminates the associated distortion that is common at high frequencies with traditional horns. The relatively shallow design does not provide the higher loading characteristics of traditional horns and hence, none of the distortion either. Acoustic loading is only increased at the lower frequency end of the drivers operating range. This provides added efficiency where it is needed most. The low frequency range of any dynamic driver is where its mechanical limits dominate and ultimately degrade its performance.

They use a first order Linkwitz-Riley cross-over design and also have a tweeter level control on the back of the speaker to adjust for various room conditions.

I don't work for them or represent their products - just wondering if anyone has heard these speakers and if so what were their impressions?

I believe the Timepiece is based on the work of Earl Geddes, a renown pro-audio engineer/scientist who used to work for JBL but is now a top level consultant. The dominate idea is to cross the low frequency driver over to the high frequency driver at the point of equal dispersion characteristics of the individual drivers. This is reported to produce a more seamless transistion. Actually, from what I understand, it is downright seamless.
