JBL C45 S8 speakers questions

[jrsevy]

I can't find much information on these speakers. I happened to buy a home in 2015 that had an estate sale before going on the market. I found that the only thing that wasn't sold were these speakers hiding in a custom made console with the console grills screwed shut. No one bothered to open it up to see what was inside! The guy who bought these speakers passed away in 1985 and they were probably not used much afterwards. The home was built in 1971 with one owner and the widow moved into a nursing home in 2007 and passed in 2012. The estate sat empty but was maintained until it hit the market.

I see the S8 components were first listed in the 1974 JBL catalog but not every year catalog is listed in the library on this site? Couldn't find the C45 enclosure, so not sure what year these speaker were purchased new.

The speakers look in great shape and they sound incredible. I saw only one pair of these speakers being auctioned in 2016 for $4700 but not sure what it sold for. I see currently many of the S8 components being sold on eBay for a lot of money. The 375 driver/HL93 horn lens now asking for more than $4000/pr! If all S8 components sell at asking, it would sell for over $6000.

Speaker grills are missing.

My questions:

Anybody have an idea what year these went on sale?
What do you think these speakers are really worth on the market? I think more than $3000 but much more than that?
If you had these and didn't need to sell, you think they will continue to appreciate?
Speaking of appreciation, I'd rather listen to these with my Denon AVS 3100X than my high end Klipsch 7.2 setup with my Denon AVS4100X - at least in stereo.Attachment 80495Attachment 80496Attachment 80497Attachment 80498Attachment 80495Attachment 80496Attachment 80497Attachment 80498

Ah, the Flair.

Fortunate find. Good luck with your sale.

If you think they sound good now, you should try them after you get rid of the hard-as-a-rock Lansaloy surround material!

Looks like 1973 for the first C45/L45 listed in the catalogs, along with the S8 system. Though the S8 actually is shown much earlier, too, at least as far back as 1962.

Thanks. Any suggestions on which I should get? I see some for as little at $40/pair. The woofers do seem stiff when I push on them. The repair doesn't look too challenging with the right tools and patience.

This has a more beautiful baffle lay out than the standard 4333 I think. Congratulations

Not knowing your experience level, I’d suggest you have the repair done professionally if you want to maximize your return. Nothing says “run away” quite like a crappy DIY refurb ... which often is easy to spot. If this is old hat, knock yourself out

This was a big project. I had to build a form that could hold the weight of a truck for laminating the curve, then cut the doors short from that and add 1/2" walnut to the edges of the doors and opening before veneering with two-ply walnut in one sheet. The two issues I had with assembly were that the curve wasn't completely square, so I had to raise the bottom on one side to get the door to line up right with the installed Soss hinges and needed to add some trim. Also wasn't confident enough in exact placement to pre-mortise the louver slots before assembly, so I mortised them into 1/4" walnut strips but now can easily pull them out after removing the screws. So, not exactly like the original plans I have but adding a center cabinet was a must for me.

My "Metregon" is 103" long and 31" high vs. 74" x 30". The re-foamed woofer sounds much better now and I also have a Klipsch 12" subwoofer in the room for extra punch.

Anyone think I should replace the diaphragms in the 075 and 375? They are original with the red wax screw seals (early 70's). They sound really clean to me.

I'm happy with the results (wife too!) and glad I didn't sell the components of my S8 Flair speakers. Now I need to see if there is any interest for my empty Flair cabinets or they're going to a dumpster.

Magnifient! I like your proportions better than the original.

Do you have any additional photos?

Ditto what Widget said, very frickin’ cool!

I need to pull it away from the wall to patch the holes in the wall with a walnut board (no more clear redwood to be found) and then I'll take more pictures with daylight lighting. I'll post that in a few days.

Almost complete and I had my woofers re-foamed. My attempt to create a modified Metregon with an added component cabinet in the middle of the curve. Just need to insulate, add my old JBL speakers and make the louvers in front of the baffle panels.

[Mr. Widget]

Very Cool!
What is your woofer enclosure volume?

I think I figured 8.4 cubic feet with all bracing accounted for. I calculated the port dimensions at 28Hz. The frequency I found for the LE-15A used by JBL is 30Hz, so I'll maybe play around with it.

As long as we're on the subject of the woofer enclosure, would you recommend adding insulation on all sides? I saw pictures of Metregons that appeared to have insulation on all but the back and the baffle. I plan on using 1.5" thick denim insulation from Home Depot. Don't want fiberglass fibers going airborne through the port from the woofer movement.

Denim is excellent. I would stick with 30Hz tuning especially since you’ll likely gain a little effective volume from the additional insulation. I would put it on five sides. Everywhere but the baffle.
