I'm moving ahead on my 4pi build.

All I need are the crossovers and waveguides and I'll be able to complete them. Razz

Thanks Wayne.

I just have to decide what color to stain the cherry veneer. After that I'll shoot it with some satin clear and install the woofers, your crossovers and waveguides (once they arrive).

I hope you like the racing stripes😀.

Regards!

My wife and I were wondering what those black stripes were.

Are they paint? Formica? A darker wood?

Google "acrytech".

It's an acrylic coating that musicians commonly use for the exterior of say, a bass amp cabinet/pa speaker and the like.

I had some left over from the last set of speakers I built and just sold- "b741scanspeak".

I only used it for the stripe because I had laid out/cut the veneer in the wrong orientation, and
I only had enough veneer left to do the front panels with the grain running horizontal instead of vertical.

Therefore, I decided to keep the grain vertical, and throw in the stripe, so you're looking at a mistake Embarassed.

I happen to like it this way, and the speaker covers will hide it if I choose.

Regards!

They have darkened quite nicely with no stain.
Here they are after several coats of clear (gloss) lacquer.

You can see the raw cherry veneer laying on the ground in front of them.
Quite a difference!

Hello all.

I'm wondering why I see so many 4pi builds with insulation installed on the bottom panel?

With the 4pi plans that Wayne sent me, under the "General construction tips", it states very clearly-

"Use R11 or R13 insulation, covering the interior top, side nearest the port and the rear".

It also says to hang a piece of insulation on the brace.

Therefore, there should be no insulation on-

1- the side opposite the port
2- The back side of the front baffle
3- The bottom.

Wayne sent me the plans about three weeks ago.
Have the 4pi's been revised?

Nope, no change. You've got it right.

Updates:

My i-phone pics suck but-

The clear, gloss lacquer has dried for more than a week.

index.php?t=getfile&id=1785&private=0


I have gone ahead and rubbed the dried lacquer with 0000 steel wool, and applied and buffed out paste wax, all in an attempt to achieve a satin sheen.

It seems to have worked for the most part, although I might call it more of a "semi gloss".

How do you all think they would sound in this configuration? Very Happy

I sourced some genuine JBL recones, so while I had them stripped, I went ahead and did the final fitment to the boxes and installed the "Nutserts" or "threaded inserts" for the woofer screws.

"The saga continues" Smile

Regards!
