If anybody would like to build a pair of these speakers, Scott Placke has generously offered to supply all the parts at the OEM price, which is slightly less than $300. You will need to call Scott at PE and tell him you want the RMAF Art Array "kit". There is no "kit", and the Art Arrays have nothing to do with the RMAF, but that's where I see Scott every year, and if you say "Fred's RMAF Art Array Kit" he'll know what you're talking about. Smile

Here's the parts list:
Sixteen #295-301 5.25" Dayton Classic woofers
Two #264-578 Vifa DX-25 tweeters
Two #255-206 0.15mH 18ga air core inductors
Two #255-266 2.0mH 18ga air core inductors
Two #027-350 33uF electrolytic caps
Two #027-408 Dayton 0.68uF poly caps
Two #027-418 Dayton 3.0uF poly caps
Two #027-426 Dayton 8.2uF poly caps
Two #027-434 Dayton 18uF poly caps
Two #027-440 Dayton 30uF poly caps
One #095-282 pack .205 quick disconnects
One #095-286 pack .110 quick disconnects
One #100-116 50ft 16ga speaker wire
Two #260-303 speaker terminals
One #081-435 pack of 100 #6 screws
Two #004-3 three ohm resistors
Two #004-12.5 resistors

The 33uF electrolytic goes in the woofer zoebel, the 30uF and the 3uF metallized poly caps are paralleled to form the required 33uF in the tweeter circuit. The schematic also calls for a 1.2 ohm series resistor in the tweeter circuit, but I found the tweeter was too bright and substituted a 3 ohm. The 12.5 ohm is used instead of the 15 ohm in Pete's schematic - this value isn't critical. To keep things simple for Scott I request that you order this with no substitutions.

Fred,

Thank you for the information. It's certainly a bonus to get the parts even cheaper.

On a seperate note, I was also intruiged by the Fredarrays you built and wondered how they stacked up against the ART Arrays? I wouldn't mind trying to build either one (assuming you dont mind someone building your arrays), but would like to hear your thoughts on if one was superior to the other.

Thanks

Nick

The Art Arrays are much better. The FredArrays were built using Silver Flute woofers and an MCM titanium dome tweeter. The tweeter had to be crossed at a relatively high frequency, and it never blended with the woofers as well as I would have liked. Also, the Dayton woofers are quite a bit less expensive than the Silver Flutes, which now sell for about $19ea versus $10 for the Daytons.

I got one of the enclosures glued up last night. 22 clamps!!!

Now I need to install the insulation and the drivers. Can't wait to hear these guys.

Super cool! Looks like a good time was had by all. I really love those little local get-togethers. You get a fair amount of time to check out the gear, and some good fun with good friends. Can't beat that!
