Fairly decent cabinet design.

I hope you are using marine type plywood.

A fine grain, high density particle board might be better. I use solid
hardwoods throughout.

You should also use a thicker glue between ALL of the elements, and you
should coat the entire inside with a thick polyurethane so thick that ALL
of the sharp corners inside become rounded.

Why?

---
Air is compressible, and when there's a pressure wave which propagates
into a corner, the pressure will tend toward infinity as the wave is
squeezed into the line describing the corner, with the result that the
wood will move and, by doing so, modulate the pressure wave, creating
sidebands.

Thats funny! What audio store do you work for?

I don't work for an audio store, I work for a consulting firm.

Bose I bet...

You're an absolute idiot. No bet required.

Besides, what makes you think it's funny?

I've been building speakers for over 40 years, ****wit.

Then you are the ****wit. Some dope that throws drivers in a box he
screwed together is NOT "building speakers", it is building CRAP when it
is you doing it, because you do not know the first thing about air and
sound. Must less the reflections of such inside a cabinet. If you did,
you would not have spewed the total CRAP you spewed.

Do you have some data you can
use to prove my hypothesis incorrect or are you just flapping your jaws?

you are retarded...

No, maniacal twit, it is YOU that is retarded.

You should not assume that your max wattage is equal to the wattage
capacity stated on the driver(s).

The wiring certainly will NOT handle your claimed power handling
capacity. It will introduce distortion as power increases. You need
bigger feed lines, and they should be kept as short as can be feasibly
done.

What sort of distortion will increase with power due to small wires?

---
If the temperature of the wires is caused to change by the charge
flowing through them, then their resistance will be modulated by the
power being dissipated by the load, and distortion products will be
generated as sidebands.

Wow! Explain the fact no one can hear the tweeter protection lamp, which
changes resistance about a million times more than the feed wire can??

---
What makes you think no one can hear the tweeter lamp?

If its resistance changes _that_ much then surely it affects the dynamic
range of the tweeter's SPL, which means that it colors the tweeter's
output, which means that one would certainly be able to hear the
difference between a lamped and non-lamped tweeter.

Does that stand for Jerk-****er?

---
Why do you want to know?

Are you looking for a dick up your ass?
---

Please go away... please...

---
Nope; I'm here for the long haul.

thats OK, intelligent people ignore fools like you

That leaves you out then.

I notice though, this is your first post here.

wrong, **** for brains, I've been around here since 95

Sure, ****head.

PLONK

Oh boy! Another total retard that thinks we are all interested in
seeing his filter file edit session announcement.

You're an idiot. Get the **** out. Stay the **** out. Go find a tall
bridge and jump off of it. What you know about speaker cabinet design
advancements would fit on the tip of a molecular probe.
