Uh-oh - 4628B's

[Zilch]

Sayyyyyy.....looks killer. Almost Sony-like, if you know which model I mean.

Actually, forum member Pangea's work inspired this design. Lemme see if any of it is still up here....

Alas, he deleted his early design exercises, apparently.

I like how you incorporated the tilt back. I like that aspect a lot. Time-alignment or asthetic?

All that, but mostly, so's they don't play to yer knees.

Key to this design is that it's got big volume at the bottom (over 2 sqft. area inside), but, because of the angles and tapers, it doesn't appear massive, an important WAF element.

Even after deducting internal enclosure of the 2118, net internal volume is probably over 4 cuft., about the same as 4628B. It's an exercise in trig for you to calculate the actual internal volume.

Time to buy a table saw, unless I can figger out how to do it with a circular.

Skill saw ain't gonna get it. Trust me on this....

Trig...trig...Oh - yeah, I remember now.

I'm farming out the plans to local woodworkers, to see if anyone wants a few $$ to try it out.

Think the Vas is 427 on the 145? Seems there's a thread about how JBL's spec sheet might be SNAFU'd.

Otherwise I'll stick with the original cab design, but I like to play with tuning points.

Make one outta cardboard first to get the "feel" of it. Fill with plastic peanuts to determine the actual volume.

Hey Zilch - I'll try to get that 3D stuff out this weekend...

Thanks, John!

I'll send you a .dwg file on this one, also.

Heh, heh.

John's got some 4628B's what could use nice boxes.

[And he knows how to build 'em, too! ]

If ya wanna get scary - -


I have an email buddy (member, too, or just a lurker maybe?) who has GRANITE - enough to build the plans, he says. He can cut the stock, and he has a contact that can polish and bevel the finished edges....and he's 5 miles away.

400# 4628's, anyone?
