The time windows are there because the watson lab model 10's are in the shop. Not for me to fix those gems.
The plinth is a custom Panzerholz, Baltic Birch and a layer of Aluminum. The "feet" are nothing more than 2" tall and 3" diameter steel bar stock. The rack is weighed down with about 300 pounds of stuff, and the thin walled "legs" are backed with duct seal!!!

Could you talk about your system, or post some links that describes those horns.

Basis Ovation (updated last year) with Airtangent Reference and Lyra Titan i
DDDAC 1794 dac wioth BP designed choke input psu
Studer A80 with selfbuilt choke input psu´d tube buffer
Lyra Erodion and S&B mc transformers
self build Thorsten Loesch designed LCR RIAA with 47kg Borderpatrol designed choke input psu..LC LC LC LC on both rails......DEAD QUIET
S&B TVC with remotecontrolled SEIDEN switches, stepper motors and belts
remote assy delivered by Chapman at Bent Audio
BP designed all out 6s45p IT 300B 2 chassis monos 50kg
TAD 2001 in Autotech JMLC full rollback 1400 nextel paint
TAD 4001 in Autotech JMLC full rollback 270 nextel paint smother sounding than shiny finish
2x Front loaded midbasshorns with Jbl 2220B alnico
custom designed SUB horn with eighteensound LW1400
subhorn lowpassed actively @75Hz 24db oct and driven by selfbuilt Holton 800 mono
sensitivity@20Hz is 92 db @30 102db will easily deliver 130db continuous @30 given the power
above 75 all is 12 db passive 24 db acoustic crossovers with Northcreek 8 or 10awg coils, Mundorf silver in oil and Duelund cast Lpad
sensitivity 112db from 75 to 22K
x/o freq 600/8K
so far all above 75 driven by 300B, but will test active LP of midbasshorns with either F5T choke input or NagraVPA amps
all is silver wired with cotton or silk sleeves...no shielding, even from arm to RIAA
still room for improvement

Hello,
Those caps are nichicon super throughs. 80V 22,000uf. They are there because I have 2 60V rails so my "ground" is at 30V. These caps are the coupling caps to the speakers and although not the optimal setup they will pass plenty of the low stuff and have a dual purpose of protecting my speakers from any unfortunate learning experiences along the way!
Cheers.
Last winter I bought a case of super throughs. The guy I bought them from had some custom super throughs at 100,000uf at high voltage. They were literally larger than a coffee can. Pretty cool.
Very interested to hear how you think the 300B compares to the F5T. Two worlds apart but still...
XOno clone with extras. 😀
