Hey unclestu52,

"I have sold all the Alon models from the 1's through the 5's, and all exhibit mismatched polarities of the drivers, specifically the midrange. I used to demo them and sell them with the mids reversed. Sold quite a few that way, too."

U have me at a loss concerning this statement. Being a long time owner of both the Alon l's and the Alon Lotus SE mk 11 series of speakers, I have tried reversing the polarity on the Lotus series midrange driver, as it has an external 3 way x-over which easily facilitates this, and found that when I did, there was a huge hole in the midrange spectrum.

Concerning the Alon 1's, unless one physically opens up the speaker cabinet and swaps the midrange drivers polarity by unsoldering the driver leads from the mid/high x-over, reversing them, then resoldering the leads, does one get a true reversal of polarity with regards to the midrange driver.

Just swapping the mid/high polarity on the Alon 1's inputs will put your tweeter out of phase with the woofer and the midrange driver will be out of phase with both of them due to the second order progressive slope of the midrange drivers x-over.

I think Carl did a VERY good job with driver blending in the Alon series of speakers and trying to second guess his vast knowledge of driver blending experience doesn't make sense to me.

With proper attention paid to room acoustics/positioning, both speakers have sounded coherent to this listener :-)

Cheers,
