This sounds like a most interesting idea and to me would be more desirable and far easier to implement than other schemes to time align the drivers.  Not even sure the effect or if it is necessary, so I really don't know what I'm talking about.

Time alignment make for more coherent sound. Personally I cant hear a difference when 8 or 10 inches or so are involved but many swear they can and set those tweeters on top and move them around. A much simpler implementation than DSP would be.

Here's an eminence apt50 on their 150 horn in a baffle on my old pair of LS.  Can certainly hear the difference. (I moved the clock when listening...)

Schweet, this is the stuff I'm talkin' about, thanks.

This is how I lined up my modified mids and tweets for a few years following @Marvel's suggestions.

And yea @Racer XI had the mids down 13.7 dB on these. The BMS 4592 can blow you out of the room.

Here are a couple of pictures of the soldered connections on the K55V driver. So far, 2 speakers have these 2 these midrange drivers and round magnet tweeters, and 1 speaker has push pin k55v midrange and a square magnet tweeter. 2 more speakers to go

This is the sought after midrange, correct?

So I finished cleaning all of the 5 La Scalas. I took an inventory of all the drivers. I have 5 - k43 woofers, 4 - k55v with soldered connectors, 1 - k55v with push pin connectors, 3 - k77 with round magnets, and 2 - k77m with square magnets.

 

I opened all of the dog house panels, tightened the screws to the woofers, cleaned off the old gasket tape, and replaced with 3/4" wide closed cell foam gasket tape.

Time to crank it up!

I got about a half turn, maybe a little more in each screw
