Kind of pricy for a robotic arm 3D print - Quoted £6K each so far
Has Andrew looked at it?
Not yet, the costs are quite heavy on the materials & finishing end. Prices drop down 25-30% on a run of ten or so. With ribbing I give you -“The whippy”

Agreed.
Extra pleasure?

You need even smaller amps due to the increased sensitivity

We have arrived at the point of producing something that might actually work!
The only part I’m not fully happy about is the printing of the screw thread for the gland to allow cables through. My test prints were horizontal, and worked fine, whereas I’m the actual thing is vertical, and they were a bit tight.
This is printed with 15% infill, could do the actual ones with 50%, or just use this as is. Not sure it’ll make any difference.

Stu visited today so we moved the TP1 cab into the main room allowing my actual amp and deck to be deployed. The test Helmet here has no top, so a nice cardboard disk a book and a fire extinguisher for weight are on duty currently. I suspect this will catch on but it’s £500 to you before the price hike.
The hope here was a Mono Source and better amp might offer a clue or two as to what this AER driver might actually sound like in this battered old cabinet.
Up sides - It makes a noise, There is an effortlessness which is lovely, there is Bass (It’s there at least when it want s to be) certain things it does are exceptional (This is often the Lowther curse, I had hoped the AER driver wouldn’t act in quite the same way)
Downsides:
I’ts shouty like your pissed Aunt with a megaphone on some tracks, enough to rattle your brain. It’s like the signal has decided to go all upfront and let the body and bass take a holiday - On other tracks it sounds remarkably good. A/B ing with the Westrex the same cuts, the AER has it in 2/10 cases the remaining 8 sound room filling but thin, oh and sometimes SHOUTY!
I’m sure the next helmet (that actually has a top) leakages and other losses may fill in a little here - better than my lash up. I will have to pull the corner of the room apart to stick the cab in where it needs to be in order to reinforce the bass (Currently pissing out in all the wrong directions)
Perhaps attenuation may help? I have an old Luxman with tone controls which may be useful to see if this thing can be tamed or if it wishes to remain rampant and aurally aggressive on a whim.
Your views @murrayjohnson @Adpully @coco most welcome - I appreciate this may start with “You’re a nob”…

I’d say the first thing is proper placement in the corners, air tight helmet in case it’s not sealed properly and then some time with rew and see whats happing with the response.

Could it be worth trying some 3d printed phase plugs with a metal instert to fix onto the exposed magnetic pole piece on the AER?
