Speakerlab 7?

[Speaker Lab]

The speakers you have are the original "Super 7" (not to be confused with the later (1981) Super 7, which was the redesign that went away from horns). they consisted of the bass cabinet from the Seven and the midrange and tweeter horns from the K's.  The Super 7 was a speaker that wasn't ever really production, and wasn't ever featured in any of the catalogs.  They were built to order in various cabinet shapes and sizes and never sold with full crossovers (most often tri-amplified with active crossovers).  If someone wanted passive crossovers, parts and general design were provided, which may be what was done here.  For folks from Seattle, the Seattle Center Lazerium originally had Speakerlab K's, but they were changed out to Super 7's at some point in the late 70's (and then changed to a full pro-audio system in the early '80's).  Our Current Super Seven uses planar magnetic ribbons instead of horns (slspeakers.com or find us on facebook).

Correct.  In a vertical orientation.  They looked like this.

 

 

I have a pair of the EV 8HD horns. They had been mounted in the pair of LS cabs I found for $100. They are almost back together with klipsch parts. They are diffraction horns and are supposed to be mounted verticle.

That looks like a standard 7 (smaller mid horn), but with the larger tweeter.  Those were a mod of the standard 7's, though sometimes referred to as Super 7's (not officially though).

That is an Speakerlab commercial ‘super’ 7 from the early days (nicknamed the Super 7 before that name was ever used officially).

 

They were built mostly for clubs and venues like the Pacific Science Center Laserium, and were always at least bi-amped (and most often externally crossed over) because the efficiencies of the woofer section (from a 7) and the mid/tweet section (from a K) didn’t match.  I have seen one fully passive set, they had a bunch of resistors on the mid/tweet board.

The crossovers all came with L-pads for the mid and tweeter. No problem with balance as mentioned above. Same size mid horn for both standard and super seven, but the drivers were bigger for the super. The photo shows the super-mid driver. I tried to post a photo showing both horns side by side to compair standard and super drivers but the photo was larger than the 2mb max size. The larger driver is a marked improvment over the standard one. Super sevens also used the ElectroVoice T350 (HT350).

Because it's true?

Does anyone have a speakerlab w1208r woofer? 

I have a pair that has one woofer that flaps. Any advice is appreciated.
