Thank you Sir! I'll be pulling at least the damaged 515 out of its home by this weekend for inspection and possible repair, along with additional pix....
Now that I have a new lawnmower battery, I can also pull the mower out of the way, and move things around so I can get to the last W-bin and see what those woofers look like. I'll post further pix if necessary....
Thanks for all the help and advice!
Cheers!
Allan

( Actually, I was more concerned in addressing your speculation that the woofs might be Jensen made / than accurately dating your 515s / others can do that better than I )
- Do your woofs have spiders like what's shown in the pic below ?

I do love the sound of these big speakers. Just so clean.
Got a chance to measure them last night, during all the partying. Below plot will give you an idea. Not the prettiest FR in the world, and they sound about like it looks. But also not the distortion. Very low. And that's obvious when listening. A.A. does use a tweeter array on top of the muilticell horns to fill out the top and and it works well.
The rig was being driven by a pair of Cary audio 300B monoblocks.
1st measurement showed a big dip at 500Hz. We reversed polarity of the horn driver and all was well. BTW, these are not the original 288s on the horns, but some newer 902s (I think).
The only think I'd like to see is to bring down the midrange by about 5dB to give them a fuller sound. I don't see any way to get lower than 50Hz, but no big deal. Matching a sub to these would be hard. What would you find that is as clean?
Thanks A.A. for letting me play. :2thumbsup:
tdsl.............what would you find that is as clean?

What is that? LOLOriginally Posted by bowtie427ss
Tom Danley Sound Labs, 2nd to none in the way of reproducing that bottom octave.
One of these, adequately powered, should fill in the bottom for as many large format VOT's as you can fit in a mortal man's home.

You just had to post that Tom right ! 
144 Db peak SPL at 22 Hz that ought to shake a few foundations "Now Were Talking" my kind of bass response.
