The grand experiment of combining the two side-by-side stereo systems continues. Still waiting on the second Schiit amplifier. The initial setup with the new-to-the-house Yamaha receiver with pre-outs is functional. Now pulling wires for extending a second zone for the office basketball TV (Go Lakers!). Once the second amplifier shows up we can shorten the wires and encapsulate them.
The new todo list is as follows:
Install new dishwasherDone
- new Guibo bush on the 128
- new center bearing support on the 128
- implement new home-theater amp to eliminate double stereo
- Trip to IKEA
Deport virtulized XP machine from my world.First test tomorrow
- Implement UnRAID and Plex all the things.
I designed a simple friction fit clamp to serve the purpose of holding two pair of Ed’s Horns together and to bolt the Heil AMT-1 tweeter.
Heil has arrived

ESS claims to use a 800hz, 3rd order crossover. Let’s investigate what capcitor and inductors we can actually get, and calculate where the x-over point ends up using parts I can find.
Lets pick out some components….
- L1 = Jantzen .5mH 18AWG $7.98
- L2 = Jantzen 1.1mH 18AWG $11.48
- L3 = Jantzen 0.37mH 18AWG $7.29
- C1 = 40uF 250v $11.98
- C2 = 2x60uF 250V $20.48
- C3 = 75uF 250V $22.98
Let’s proceed to set this up though, let’s model these values in software and see where the x-over point is…
Looks like it hits 806hz at these components, good enough for me.
Update:11-19-19 The Heil has arrived. After some deliberation, constructing a dedicated passive crossover for this setup is inflexible, and given the consideration that I am unlikely to stick with ‘The Horns’ for much longer, I am better served moving to a solution that I can re-use in the next speaker I use. Active digital crossover inbound, and another amplifier.
Good news, the Xterra runs great. Bad news, I continue to never ever get a water pump to seal on the 1st try. Every time, I follow other people’s advice, and use ‘recommended’ sealants, applied in a neat (thin) way. It always leaks. This always results in purchase of a new gasket, followed by gooping the living shit out of it. Bet it works this time. New timing belt is re-installed, hasn’t been tensioned, need to roll the crank a couple times and put my 22lb on it.

Testing embedding…So…. suppress this iframe and the menus disappear. Well, that’s fun. Ok, time to ditch this not-so-responsive theme from 2012….
Due to a large fabrication project underway I have a lot of box steel to chop up on my vintage Rockwell Model 7V. Blades are not cheap, and I have them made for me. To this end, preservation of the blades is a priority. Designed a magnetic base with captive rare earth magnets, a combination of 6mm and 20mm rare earth units fit, is compact, and secures the mist solution very well. I use sta-lube water soluble oil diluted at roughly 10:1
