Thanks to both.
I'm working on a test box, closer to 24" x 36" x 48", just to ring out issues.

I've about to set up the baffles and hardware, when some questions arose.
I read the 4350 notes regarding how to change Rt / Left sides of drivers in the enclosure, but am not fully satisfied I...
Outstanding work. Thanks for sharing. Beautiful veneer work.
Mark.
JBL rebuilds and this community has been a catharsis for my edification and it is frustrating to observe steps taken in this industry which also financially succeed at the detriment of the components...
Same as the link you posted, just at the bottom of the page.
See appendix A It has some useful equations.
Here's an interesting bit of acoustic pornography:

If I recall correctly, they are part of his system down in Rancho Mirage, or at least another forum member here in SoCA.
This topic has caught my attention recently for a number of reasons.
Firstly, there are a number of manufacturers of speaker/transducer systems which now use ultrasonic systems to project sound...
Might try here. The bidding ended at about $10 and reserve not met. You might get him to send you a pair.

What were the symptoms of dying and dead? Were they corrosion or small conductor size in adapter connection related?
Let us know how the increased volume and 2235 H separation sounds.
Are these tuned, then, a bit lower than the 4355s? i.e larger enclosure volume?
I've laid out a set for the 2235s to be only...
Gorgeous and practical height.
The grills also look more managed in that configuration.
Along these lines, I've also been curious as to the best design of the enclosure chamber in a ported enclosure. I would think an egg shaped interior might be better suited but it really depends upon...
I've been toying with various 4350 baffle configurations, trying to conserve floor space real estate, while maintaining the alignment of the voice coils and and aesthetic baffle. The midrange horn...
Those Cable supports look they'd go nicely with some air break switches. (always wondered what people did with old ceramic line insulators.)
To emphasize the consequences of say, let's allow skin depth to matter,...worst case in some calculations imply the resistance of the wire might increase for AC loads as opposed to DC calculations...
A simple example.

No problem.
Probably the only thing worth quoting is:
In a nutshell, for copper, the skin depth or depth of penetration of the plane wave, delta, is typically 0.85cm for 60Hz and 0.007cm at...
Very nice work, Huynh.
Thanks for the input. I might just go back to the 4350 baffle design and place the midrange and tweeter externally.
I've also toyed with mounting a couple of amps in each box and just running...
Thom, do you know of any good basis of design commentaries which discuss at what point one shifts from direct connections to distributed sound reinforcement?
For others, IMHO, the significant...
From past studies in Mat'l Sci, I'll try to answer yur question, although I haven't taken this to the lab recently, and I suspect there may be some others in this forum who are also better qualified...
