I see that the satellites for this speaker have a 2 1/2" full-range driver. I've seen other similar systems with very small drivers. I realize there has to be a tradeoff in bass response vs. treble response, especially off-axis for the latter. Generally, a driver's off-axis frequency response starts to decrease when the waveform's width approaches the driver's diameter.
I've seen full-range drivers (4" to 5" diameter) that appear to have a fairly good frequency response, including up to around 20 kHz and down to around 100 Hz. I have not seen off-axis frequency response curves for these drivers, though I guess they are not great given the reason above.
Given B & O's use of the ALT with many of their tweeters to expand and control the off-axis high frequency response, I wonder if a similar waveguide could be used with a full-range driver. The challenge is that I think all of the tweeters using the ALT are pointing upward. I think that with a full-range driver, it would be best for the driver pointing horizontally. With the usage of built-in amplifiers and cross-overs, the treble response could be increased if needed at the high end. The waveform guide would merely distribute the high frequencies equally. I would expect that at lower frequencies, provided that the waveguide doesn't totally cover the driver, it would not have an effect on the sound.
Any thoughts as to the practicality of this?
