Perhaps a cotton diaper would be more appropriate. 

Diaper packing it is.  :thumb:

The enclosure for the 15" woofers (I have Acoustic Elegance and Volt woofers to try out) is still being designed and the mid-high section is being developed and measured. Things are going really well, I am very happy with the sound so far. I do intend to try an 800 Hz xo point but I expect it will end up much lower... it depends on how large the waveguide will be, a very large waveguide is technically ideal and would allow for a lower crossover point but there are tradeoffs that need to be balanced. So far the soundstage and imaging is the best I've heard from any speaker at any price, the room boundaries disappear and the stage depth is far past the rear wall and extends up in front of the speakers in some recordings, with a realism like you can reach out and touch the image. So I'm very happy but there are a lot of challenges too!  :green:
I'm building similar speakers. :) AE TD15m/SEOS18/ba750.

Since we are getting off topic while the Crown moves around, I have a favor to ask. Rajacat and DaveC are posting about new speakers. I'm a speaker guy and always want to learn what others are building. So guys, please post a link or two about what you are doing.

On topic. Something has started buzzing in my system.  I've got the Crown eliminated as a source. There goes my 1500 break in time as I try to find the problem. It might be the outlet itself isn't grounded. We've had a bunch of problems.

I had to fire a contractor for substandard work. I bet he skipped the ground wire.

Just make sure it's not a used diaper!  I hear one will make your system sound like... :roll:

OK, first the cryo vs stock. Gotta say, I'm a cryo believer here. How did they stack up? Cryo was a bit more fleshed out (better able to make out harmonics and the resonant qualities of acoustic instruments) and a bit more delicate. Other main difference? Bass. Better impact from the cryo version. Imaging also seemed improved, though that's not a real strength of my set up.

This is with same cards for both amps.

So far, I've become a believer.

That said, I'm worried that for either of these amps, the highs could become fatiguing at high volumes. With these quite forward speakers. Something I'll be paying close attention to.

A different power cord could easily solve that problem. What power cord are you using?

Very nice Roscoe!

The way you described the cryo version is how I would detail what happened when adding both of the Hammond chokes in my system with the crowns.

It is  a big burly thing and hardly a stock cord, but I'll have to check the model. Power cords are on the to-do list...

rajacat, sounds great.  :thumb:  One of my challenges is I'm using a cone driver and not a compression driver in my waveguide/horn and there isn't a ton of info on the subject. I'm getting great results as far as the sound but the boost in efficiency is greater than I expected. It would be very simple to build this speaker without any waveguide, but the qualities it brings to the table are worth it imo.

steve f, I have no further info, but at it's basis it is a FAST with a waveguide. Simple in concept but complicated a bit by controlling directivity of the full range driver. I hope you get the electrical figured out!

roscoe, thanks for the report! I have found that most things need a little time to settle from shipping, not a full break in but you'll probably get at least a few hours of edgy sound.

When I get the Pomonas in, I will send those to Salis Audio and then off to the Cryoman it goes. :D

Dave is right, let the cryo amp burn in 24 hours straight before you really judge it. I have found this is the case with all components after it has been transported or shipped.

Yes, even now the treble is sounding less harsh and fatiguing. Will revisit some earlier tracks shortly. Then time to try these bridged into mono!

Do you have the amps marked? Don't send the crro'd one off to Chris.

My plan was to flip a coin. But if you'd rather, I will scratch “cryo" into yours with my car keys

Returned to music I'd listened to earlier, and treble is much less of an issue. Now time to change the power cable...
