System Pictures & Description

Almost done with the cinema: 24x 3fe22 for LCR, 2x 4fe32 for surround (1,5 way), 4x 15TBX sealed for LEF and a 3m wide AT-screen.
Was going for a DBA but at the moment I cant justify the cost of 4 more woofers.

Hard to photo a dark room.
 
Messing around with these 4 way dipoles modeled on Linkwitz LX521.4. Drive units from top to bottom are Neo3PDR Tweeter, SEAS FU10RB Upper Mid 4", SEAS SEAS U22REX/P-SL 8" Lower Mid all without baffle, SEAS L26RO4Y 10" SUB in H-Frame, crossed over presently at the same points as SL's 7kHz,1kHz & 120Hz, but with variable ASP based on 3x Nelson Pass' DIY BIAMP boards.

There's a vid on YouTube of someone punching a sub to generate electricity to light up leds, I think he broke his hand - not realizing he'd be hitting the speaker magnet after about an inch; but perhaps some active bass traps could recover some power.

Refreshed AR XA turntable with a Shure M55E cartridge with a new stylus so I can keep track of the hours on it.
Feeds a Little Bear phono stage, and volume is controlled by a new 100K carbon film resistor stepped attenuator in an old teak case, originally using a 10K attenuator intended for all solid state set up.
Not state of the art, but good enough for me controlling a little highpassed 10 watt class A power amp and a plate amp for an open baffle stereo pair and open baffle bass panel.

Pretty :^)

What MacBook?

Thanks, it's just a 15" M1 MacBook Pro for work. My desktop is hanging off under the desk in a custom carrier/hanger (desk is height adjustable). Annoyingly the M1 has issues with audio stuttering outputting over USB when low on memory.

So instead I have a Raspberry Pi sitting behind it running a Mopidy music server and raspdif which gives me SPDIF output from it via the GPIO to the DAC.

Nice build. How do they sound?

Great to my ears (and others that have listened to them). Surprising amount bass for such little speakers! And I never find them fatiguing. Just all around a much better speaker across the range than some basic JVC bookshelves I had previously that were much larger than these. I put a lot of effort into making them, so to say I was relieved when I heard them is an understatement!

M1 MacBoook Pro cam ein 13, 14, 16” sizes.
Ah yes you are right, my bad it's the 2021 16" 👍
 
It’s not stable yet. The most disappointing thing is the sound wouldn’t play through the hdmi or usb ports, just through the tiny mac speakers. The last version I was experimenting with was Ubuntu and it was working pretty good. After about four different versions of Linux my M1 forgot how to boot. I had to do a factory reset and reload from time machine, it’s fine now. I like Linux as my music server though.
