yup. easy to do. Don't put too much on, spin around as you work.
Better if speaker is out of box.
Turn upside down to dry; especially if voice coil is "open"

Can find it on ebay OR here - remember 118. Its on the second 1/2 of page:

Yes, a couple of annoying glitches.

I took grindstone's numbers and ran another sim using your vent sizes. Box is 18.5L @57Hz tuning. You'll notice the vent length is quite a bit less, due to the higher tuning.

Likely that grindstone is just measuring at a different part of the T/S curves. Computer driven measuring kit is often this far off factory measures (my own included -- i always start with the factory numbers).

Default FWIW

Mine were neo's and over a year ago. Second, I'm not far from Dave's position--I hedge somewhere betw mfr data and what I measure when doing sims.

I had planed on finishing these this weekend, no such luck.

Might have them together in week or so. However, so far so good, I like the proportion.

Top is not glued - only glue one "side" at a time (I don't like glue running all over).

Default Picking up speed

Picking up speed, but only have a few hours into this so far. Going to tune it up today.
The white screen is a blocker to keep the damping material from blocking the ports; found it in our last pizza box order. I may have to go order another pizza for the second one.

Will probably just throw the pizza out and keep the white screen - the pizza was terrible

So forum question, is the full range woofer too low?

Not glued, could cut another front baffle.

I do like TVR's "rounded over" thoughts.

Default Gaskets

I'd much rather pay an extra dollar for factory gaskets, vs. making them. One resin not to buy less expensive speakers, have to spend more $$ fixing them.

Might put some hard wood on L&R panels (for looks).

So far so good.
