Nice, there's an EVM12L model in there.
I have two EVM-12S drivers in two Thiele cabs that I built based on a set of Electrovoice plans.The 12S speakers sounded almost identical to the 12L's in a Mesa Thiele cab when I compared them. I also built an EVM-15L in a 15 inch Thiele cab from the same plans.
I pulled the 12S drivers from an open back Fender Silver Face cab that I originally bought to use with my '68 Bandmaster. The cab was in great condition. It looks like it was made in 1972. I got lucky with the Bandmaster. It was made in February of 1968. It is a factory AB763 (Black Face) made from parts meant for '67 Blackface amps.
The cab was smaller than a Bandmaster 2 x 12, which originally came with either Jensen or Oxford drivers and was closed back. So I bought plans for a Bandmaster cab and built one out of pine to spec. I mounted a pair of Jensen C12N drivers in it.
I was planning on building a pair of 1 x 12 cabs with Kemper drivers. Now, if the Kemper Kone Oxford voice nails that speaker, I will need to build a 2 x 12 cab with Kemper drivers as well.
I will instantly try a Kemper speaker in one of my cabs and compare the sound when it becomes available as a part. If the Kemper Kone nails my home built Thiele's sound, I will go with the Kemper speakers and make a 2 x 12 + 1 x 15 Thiele cab with the 12S and 15L speakers.
What is a 2 x 12 + 1 x 15 Thiele cab!?!?
It is two vertically stacked Thiele cabs with a slanted front on the top and a 1 x 15 Thiele cab under the two 12 inch cabs. So from top to bottom it looks like this:
12 inch Thiele cab slanted back by 16 to 24 degrees
12 inch Thiele straight cab
15 inch Thiele straight cab
All 3 speakers are 8 ohms. So I will do some creative wiring. I hope to set up the cab so I can go 2 x 12 mono and 1 x 15 mono in stereo. That would get me a 4 ohm load on the 2 x 12 cab and 16 ohm load on the 1 x 15.
I might also get another 8 ohm 15L so I can configure the cabs as a 2 x 12 + 2 x 15 standard cab. I will design two cab bodies, and use removable baffles so I can get the best of both worlds.
