Ok, I am just moving my Peltier device electric fridge downstairs with food and beer and not coming out until Jan.

Best speakers I have ever heard in a real room with a great soundstage width and depth.

It all works! :shock:

Ice is easier ;) Just put the cooler w/in reach of the listening chair. Then all you need is a catheter :obscene-drinkingcheers:

Yeah, but you have to keep adding ice. I just plug it in.

Bathroom is around the corner. Then you can do both.

Back from lots of travel and more speaker crossover tweaking to go.

Met Richard Schram from Parasound at RMAF2017. We talked about music, the line arrays and the Parasound Halo A23 amps that I was looking at as a possible alternative to the ChipAmps. He made me a deal I could not turn down, so now the setup has 10 - A23's and the Rythmik HX800 servo amps installed.

The DSP crossover 2x16 prototype is working well and more measurements and tweaking are happening for 2018.

Man, that's a lot less loose wires, makes it harder to show a picture to the wife and say, "See, it could be a lot worse". ;)

All the 20 amp channels are complete and tested. Power conditioning arrived, so now it is time to install the tweeters and connect everything.


Rich,

How are the channels configured? Based on Frequency, Driver or both?

Shashi,
The frequency response for each type of driver is the same. The time delays for pairs of each type of drivers are different, so you need the different amplifiers.

Is it a 3-way system? What are the crossover points and slopes?

It is a 7 way speaker with 2 crossover points. The rest are time delay differences.

Still deciding on what they are exactly at this point. Approximately 150Hz from subs to planars and 6KHz from planars to ribbons.
