Fantastic work Rick!

I hope you don't mind that I've forwarded these photos to Greg.

Great work on the grilles and super set up all the way around.

What's your winter project this year?

Thanx for the comments. I've burned through about 16 yards of blue Zilch cloth making 11 or so pairs of new grilles and covering a couple others. I now have grilles stocked for all of my projects. Am now cutting wood to finish the pair of 4344's I started a few months ago and hope to have them done sometime in December - not sure where they're gunna go yet as the house is full. I have one of my 4341 pair remaining to be restored and then I'm on to restoring a super early pair of 4350's that I've been anxious to bring back to life. Never a dull moment in JBL World !! I need to somehow put the stoppers on after that and just sit on my ass and listen for a while. We'll see. Rick

Very impressing work indeed.

Between those beauties that rather big TV looks really small.

Great work. I could look at those all day - actually takes my breath away.

Two places that could probably help you out to get the blue stain the way you want.

First, the Musical Instument Makers Forum. If you create an account, you can post questions, and they are VERY helpful. You aren't making a guitar, but you want to use a technique that they often use.

The other is Luthiers Mercantile International. They have all kinds of finishing supplies, dyes, etc. that could be of use.

Those are beautiful cabinets. It would be nice for you to get the blue the way you want them.

All the Solen parts for the biased 3155 equivalent filters.

Can you say "Awesome" boys and girls? "It's a wonderful day in the neighborhood" for sure.

Most of you guys know me well enough by now to know that I'm FIRMLY stuck in my 70's 43XX/Sovereign groove and just can't see any merit in moving out. Having said that, there's nothing wrong with tweeking these old speakers to achieve their maximum capacity. The prospect of electrons flowing thru modern state-of-the-art x-overs is exciting.

Whenever I hear mention of these, it sure get the wheels turning.

Rick, you gonna run those with 40's or 41's?

Thanks Chuck

When I first built them they were populated with alnico 4350 components which I had on hand at the time. As parts came available I changed them to 2235H, 2202H, 2441 and 2405. They are currently running on 3107's and sound pretty good. I'm sure the new x-overs will lift them to a new level. Cabinet volume is the same as the 4350 and 4355. I'm a bit worried that my 4350 port arrangement may not be correct for the 4355 components. I'll need to get with one of our forum wizzards who has the knowledge and software to determine if I need a change in port size or duct tube length. As you know, building a box is one thing but making it sound the best is another story. This project will certainly be ongoing, at least for a while. I'll keep you posted.

They must sound a bit bright then.... or at least have fairly indistinct highs.

Even if your new networks weren't charge coupled and even if they were using standard mylars they would be a significant improvement.... as it is you'll be getting new speakers.

For a friend in Aladambama I build another pair of my living room friendly 4351 Vertical Monitors. They're pretty much identical to mine in finish and components. They were temporarily parked in my wife's living room until this past Saturday when we loaded them for their trip to Birmingham (she was happy to see them go). At 300# a piece I was glad to finish the loading and kiss them goodbye. On to something new.
