I love watching you work! Just the bit where you are using the plastic scraper to scrape the glue off the front baffle surrounds was satisfying - it was even a shame you cut it short!
Hi Matt . I enjoy watching your refurbishment process. Cabinet work ,drivers etc . I understand what the crossover purpose. But I don't always understand the technical speak though. Keep up the good work. Allan
Does the protruding lip on the front of the cabinet and the very thick front cover affect the sound? By today's standards it seems to do almost everything wrong. The drivers seem to be very deep in the cabinet. Must affect the tweeters dispersion quite a bit. Be interesting to see how the numbers look on test.
@@haycrossaudio5474 keep em coming Matt, I’m looking forward to the Celefs. I know it’s extra work but the audio clips at the conclusion are always interesting. Remember the Studio 1’s 🤣🤣
Are you not tempted to chamfer the edges of the cutout in the grille panel, or even widen it too, in front of the tweeter? So far in front of the dome, surely the straight cuts are going to cause diffraction and make them audible as sources, seriously degrading the imaging?
I'll see how the measurements go. With the tweeter though the wavelengths are so short and the tweeter will be almost beaming like a spot light the covers won't really have an effect. The mid, maybe. We will see when I get to the measurement process
@@haycrossaudio5474 I'll be interested to see what you find. I have a pair of Acoustic Energy AE1s, with similarly thick but more robust panels behind the fabric, and lining the upper part of the cutouts (i.e. around the tweeter) with the felt used on the LS3/5as made a significant improvement to the imaging - indeed made the speakers 'disappear' just leaving the image. (I did that because i couldn't chamfer mine.)
Thanks for posting your vids, they've been really helpful (doing some work on my old pair of Kef Concord iii's at the moment..). Quick question though - have you ever tried solvent based 'wood hardener' on chipboard? Or have you found pva always does the job? I was thinking 'wood hardener' seems to turn stuff to concrete which may or may not be beneficial especially for the internal joints in a cabinet.. Thanks again for sharing
I'm overthinking, but why not stiffen every older cabinet by soaking in pva? I've never tried but.. Or I suppose it's obvious - it's no longer a repair you just a change in the sound, for better or worse.. All the best!

Did you know the CELEF brand name was from a mix of Kef & Celestion. Which there first speaker contained?
Yes. Stewart Tyler was the designer. CELEF stood for Celestion tweeter and KEF bass driver 😊
Or if you overdo it with gluing or wood hardener or trying new bracing will you just deaden the tone?
Hi Matt👍👍

@@pol-gj6qm PVA works really well to bond frayed edges and loose fibres. I use Gorilla Glue. Works really well
@@haycrossaudio5474 Thanks for replying - do you use it to run down the joints inside the cabinets as well?
