A little more investigation. The Walsh tweeter is Infinity PN 902-0060. It is a "super tweeter" operating above 8000 Hz which explains why it's up firing. Its only use is to provide "air" around the notes. If it were me doing this, I'd look for a planar tweeter and run it in dipole mode. However, it MAY be possible to get a "bullet" tweeter, point it up, and try it with different values of capacitors and resistors to blend it in, but it would be trial and error without measurements. Even with measurements it could be a challenge.
What drivers did you replace the mid-domes with? How do they sound compared to the originals? I've got QLS-1s also and this intrigues me.

Hey seifreit, you commented in the refurb thread, I posted the planars I used there...

So yeah, I refurbed the crossovers in my quasi-Quantums a dozen years ago and have enjoyed them ever since. Except for the Philips dome mids that were installed prior to my ownership and the crappy mid-bass couplers someone slapped in the baffles. I took care of the midbass with a pair of...

Thanks @jimreeves . Now that I've looked at this I remember reading it when you originally posted it. Can't believe I didn't recall this. BTW I noticed you also replaced the mid-bass coupler, a Peerless 5". Do you recall the model number for that?

It's a discontinued Peerless driver. Because it's larger I had to make a 3/4" baffle extension for it so the basket wouldn't touch the hole in the baffle. I considered going bigger still, but this driver doubled the xmax and power handling of the Philips driver Infinity used and it still fits within the transmission tube that runs through the cabinet to the back.

Well I messed up on my first reply, if it's repeated, it won't be exact but the picture will be in this one for sure.
My first thought was, a good idea but it's certainly missing something, for someone with your expertise in several different crafts, you'd have be foolish to pass up the chance to lay another down in the opposite direction!
Making the first TMWWWWMT center is something that a pro like yourself cannot pass up. I can confirm that no subwoofer will be needed if you have a double cab center. What would a double cab length end up being?
The 118" TVs are pretty common now so, I think that would be kind of a no-brainer. I made a center using Hersey horns and 2x 7" drivers, I was trying to keep it a small as possible, ended up a tiny thing of just 27" wide 9" tall and 12.5" deep. The miracle of it is it survived a fire that burned in the same room. Flames licked it, and a set of Heresy's that were right next to it and all 3 are in perfect working order after some glue to one woofers bottom edge that had water sitting in it for a few days. The paint I spent months polishing has an alligator look now, the regular cabinets are charred and I peeled off the top layer of what was mirror black lacquer along with the first layer of plywood.
Made it to sell as a set since I don't do surround. They survived while many others met their doom. My beloved electrostat build which used woofers from Kappa 7s for the low end did not survive intact. All but 4 lonely infinity Panels (out of 28 total) melted that night .
The good news is the kappa woofers and the monitor audio woofers all survived the intense heat and are still fully functional. Although one monitor audio did take an axe to the dust cap but only to bounce off leaving a dent with a small hole. Other speakers melted into molten plastic blobs but the strange thing is the foam surrounds that I replaced are all still attached and soft?
I used the cheapest crap available (we all know it's made in the same place no matter how much you paid) never bought that USA made stuff (that doesn't exist) in my life and I'm glad to see that it passed the true test. Driver cones are gone but the $2 foam was in perfect condition?
Other survivors are my entire vintage front end and all XLR cables, even though the couch in front of the set up was gone and the TV just a few inches behind the stack was melted into a blob, the other TV to the left was a blob, the Biggest TV on the far wall was melted on the same rack that both amps that I'm using right now as well as an old Peavey CS400 amp that I just tested today and all 5 of my BGW amps all still work. They were under the TV stand and the newer (less than a year old Chinese back up amp) which was next to the BGW stack died along with a few other surround receivers in that stack.
Another survivor that was right in the middle of it all was a pair of Aztec Picasso speakers that lost their grills to the flames but the paper cone drivers are all fine. What's really strange is a huge stack of glossy and regular printer paper, maybe 10,000 sheets or more was untouched but everything has smoke damage and I tossed so much in the trash over the 2 weeks that followed. I finally got to move back in after a year of bullshit excuses from the contractor who I'm now going to have to sue to get the job finished and some money reimbursed for stuff I had to buy due to their incompetence.
Bottom line, buy old gear if you want it to last a while, avoid fires, never expect a fire to resemble anything you've ever seen in a movie or TV. You'll have only seconds to escape with your life, you'll never have a chance of entering a fire even if it's small and has gone out when you return. You can't even see your hand in front of your face, you can't keep your eyes open for even 1 seconds due to smoke, you have zero breaths before your choking, you will be disoriented even though you know where you are, it's pitch black, your eyes are closed and burning and your choking, you're not running to get any belongings. Best bet is to know if there's a window you can break and jump out before the smoke overpowers you. I know this from returning to the already burned out fire and expected to spray my hose inside so I could see what happened. I could only get 3 steps inside before I couldn't see and had to drop to the floor and crawl back out.
I had to wait for hours before I found out if my money I had stashed was still there or not. The longest 2 hours of my life. I was lucky and it was all ok. If it burned I would have been homeless unable to pay a big deductible and had nothing but soot covered junk.
Stash your cash in your freezer it's the last thing that burns. Fire Chief said most freezers go unburned even when the structure is gone. Mine went out on its own and still unsure what happened. Oh yeah, kappa woofers are some tough drivers! Other Infinity stuff, well, not so much, from my experience!
Be safe, have an exit plan for you and your family, fire is scary as hell in real life, you only have seconds before smoke overtakes you!
