They might sound a little quiet that way, but they sure look great! Laughing

I'll venture to say,
they would certainly be the most "transparent"
speakers I've ever listened to Very Happy .

Work has been busy for me, I'm about a month late to finally posting these build updates/pics Shocked .

I got the horns recessed/routed 1/4" in to the cabinets. I had to make a jig that I clamped on to the cabinets, which took longer than finally routing in the recess. This was somewhat nerve racking, as the veneer was already installed, but it worked out fine.

Although I understand there is no measurable difference with the exterior surface of the horns being coated vs. uncoated,
and many can not hear a difference, I chose to coat them anyway, since Wayne says it can't hurt. I suppose this could be described as the "herding instinct", where you see so many others do it, you fall in line and do it yourself Very Happy.

I used "Gardner Bender Duct Seal", to coat the outside of the horns. It is non toxic, resists high heat or cold temperatures, and never dries out. It's also extremely sticky. I used two pugs per horn, 4 lbs. total for both horns.

I made speaker covers using craft sticks, 1/4" thick x 2" wide x 4' long poplar sticks from the Depot, doubled up in thickness.
I cris-crossed the ends and used wood glue throughout.

Found some see-through material at Joanne's Fabrics. It looked similar to the acoustically transparent, black material I have gotten from P.E.

I'm hoping it will be just as acoustically transparent, as while holding it up to the light, I could see through it just the same.

Now It's just a matter of hooking up the crossovers to the speakers, and letting them rip!

I consider these speakers a success Smile .

I have been running them for two or three weeks now, and they are sounding awesome in general.

They seem to have an initial break-in period, sounding better and better (especially the bass) with time.

These get louder than my last set of speakers, so no need to crank up the volume as high.

The 4pi's seem much more dynamic than my old speakers as well.

Its nice to have bass response that you can clearly both hear and feel, instead of only somewhat hear and not at all feel.

I have been using my old Adcom 555 (somewhat sterile) s.s. amp with these speakers, but I am now going to try a tube amp.

Ill be building an ANK 300B kit-1.

I have read on numerous occasions, that these set amps work well with these 4pi's, and some other high sensitivity speakers,
so i'm going to give it a shot.

Excellent!

That's going to make a very fine system.

If you have time, please post pics of your amplifier build as it progresses. Then you'll have it permanently documented for prosperity!

I didn't take very many good pictures of the amp build, I pretty much assembled one board at a time, and then photographed them.
It is almost complete now.

I was not very excited on taking many photos to show, because of the crummy, low resolution results I usually get from my i-phone.
Although, looking at the photos uploaded, some look a little better than I thought.

The pics are out of order. The ones with the transformers next to the chassis was at the beginning of the build, where you feed their wires through the rubber grommets of the chassis.
