And you're considering doing my fantasy- a row of ACA's! How cool that would be!

I think you'll love it
The mid horn driver is 16 ohm. Would 20 watts drive them properly at a reasonable volume? The others are 8 ohms.

Would you recommend including the Soft Start & Speaker Turn-On Delay and DC Protector Boards?

The ACA amps will run the Westlake speakers very well. Go for it!

As for power, being quad-amped makes for good use of the available power, and will likely be much louder than you expect.

In fact I will use 6 of these for now but will order 8. Once again...the soft start circuitry sounds like a good option to add? Can I get some input on that?

The red and black is the direction I am going

The amps don't draw much, and it depends on how you're powering them. The supplied PSU's don't have a big input surge like a linear supply would, and each one is pretty low, so what's it gonna be for 6 120watts? Not much

Smart to order 8 if you're getting the red and black. There's a mystery soft-start project we're developing that will be perfect for you. In the mean time just turn on the big amps separately.

Softstart is completely unnecessary on the ACA. It has no capacitor bank to charge.

This is going to be fun. I will place my order right away. I see your in Denver and was wondering if you attend RMAF. I consult for resonessencelabs.com and have
worked for westlakeaudio.com as well. Will be there this fall.

I have done a fair bit of soldering in my day...but only have a very basic understanding of circuitry.

Looking forward to this.

I live not far from the RMAF venue and would love to meet up there!

Shoot me a PM and we can coordinate.
