And Yet More JBL 4430 Stands

[day67]

Nice work! At first I thought the stands were part of the speakers - and that's the point.

A narrower port will cause 'dynamic compression' at high power levels. I would change the length of the tube leaving the port size the same.

Interesting, thanks. My problem is, I didn't want to make any permanent changes, plus longer (?) ports would hit the back of the cabinet or stick out of the baffles, and shorter ones (?) would require cutting them. But I'll chew on that. I seldom crank them up past 95 dB or so anyway.

Anyway, maybe I'll add some WinISD experimentation to my get-around-to-it list. (And someday I'll post further on this point, on my other thread about the ports.)

Great job! Will your leftovers fit my Apollo's?

Thanks!

I'm afraid the dimensions would not be the same. Plus, all my extras are long gone!

OK, with the material left over from making my 4430 stands with round corners, I've now made some with square corners, to match the speaker cabinets better. As with the others, these are also made of 3/4" walnut veneer plywood, with solid walnut corners and 2" nonskid rubber casters hidden underneath. The backs offer plenty of room for outboard crossovers and the stands provide a nice 5" lift.

After this, I am DONE. This was way too much work for my lazy ass.

(Obviously, the casters photo is of the round-corner pair, but it gives you the idea.)

Oh, I must of bought those from you then, I have a set just like that. Love them!

Mazel tov. Funny how these stands turn up from time to time. On eBay I saw some 4430s with my stands; the listing stated that the stands were “made by a JBL engineer”. Haw.

Right on! Those are the later versions; sweet.

I love them, easy to roll those heavy things around!

Excellent. They were a ton of work; I think I made about twenty pairs. But I'm glad I did it.

You mean you're NOT a JBL engineer but simply a Professor of Plinthology??? In that case, you should have been a JBL engineer!
