Hello Adam,
I actually use four Evid 4.2's for this exact use. They only have spring clip connectors on the back...that bites.
To work around this, I installed two NL4s on each Evid. I wire two of them on pair one of the NL4, and two of them on pair two of the NL4. The unused pair is passed through the speaker so that they can be daisy chained. With each Evid being an 8 ohm load, all four of them load both channels of an old Carver pm1.5 nicely.
The real beauty is in the flexibility of this string of Evids...I can put pairs together to mimic whatever stereo spread I have.
ie - ONE-->--ONE-->--TWO-->--TWO-->-->-->--AMP
However, when dealing with a theater with a loud pit...I put a pair in the middle and spit the opposite pair. This allows me to run my vocal front-fill matrix louder in the middle.
.............Really Loud Pit..................
ie - ONE-->--TWO-->--TWO-->--ONE-->-->-->--AMP
Of course, these speakers need a significant high pass for protection as well as a bit of high shelf cut to smooth them out a bit.
I have used them to front fill comedy acts, theater, worship bands, rock, and symphony. Initially, I was going to place a DPDT switch so that each speaker could select pair one or two...but that could potentially drop the load below 4 ohm...and the old Carver would not like that very much.
I can post some pics if you would like.
