I'll make another run at the impedance measurements including a check on a known-value resistor. The planar and woofer measurements were done in exactly the same way, one right after the other. You'll have to be a little more specific about what you mean by "loop back sanity check" in this impedance testing context.

Checking a know resistor is a great way to test what is happening. I'll look in the manual tomorrow to see the correct way to do a diagnostic loop back. Kinda tired tonight. Long day.

According to FedEx tracking the new amplifier should be here Friday. I hope it just plain works, with no surprises.

While waiting for it I completed the cabinet that hides the electronics and is intended to "tie the room together." (That's a Big Lubowski movie quote, in case it isn't obvious.) It's actually supposed to tie the room and speakers together (round woofers, round cabinet handles...get it?) but I couldn't find a quote that accommodated speakers. The old amp below the cabinet is the temporary one keeping me in music until the new class D amp shows up. Things should look tidier once the amp is gone and the extra cable mess is eliminated.

I realize the diyaudio crowd isn't likely to be overly interested in room decor but I'm sort of dead in the water until my electronics are back in order and since you asked for an update, I'm posting a crappy compressed iphone photo as project life support. I do appreciate the expression of interest!

Well Sir Few I have to say it looks smart.

Done a fair bit of design work over the years and I'd be very proud to say they look really professional.

Thanks Mark. I appreciate the supportive comments. As usual, construction took longer than planned/expected. Is that part of the definition of "project?" It seems to be in my experience. I think I hold the title of world's slowest painter of cabinetry. I swear I sand off more than I apply. On the other hand, the top slab of cherry was hand-planed and I'm pretty pleased with the result. My wife gets credit for the idea of hanging the cabinet on the wall rather than using legs.

Nothing promotes acceptance of large speakers like being involved in the design!

W.A.F. (wife acceptance factor) is an acronym for poor communication.


Nice to see the end results are appreciated all around.

Now you must burn a pile of boxes to the courier gods.

I'm not sure how many readers are familiar with this site on diy audio projects. It makes for fun browsing. My towers just got added to the mix.

By the way, the new amplifier has arrived, is installed, and seems to work without glitches. Hooray! That allowed me to get the limp-along amp off the floor and neaten the set-up a bit. Pardon the mod lighting---I was fiddling around in photo-land a bit today and got "creative" toward the end of the session. The photos on the homebuilthifi site are more straight-shootin'.
