Ok, here's the resistor option that I mentioned in the Vancouver GTG results thread, here: Vancouver Summertime GTG Results
Seems to me a few people thought these were a tad bright, although this is the first I've heard this remark. No one said it was a deal breaker, but we're after the best. Of course, sound is a subjective experience, so this option is for those who prefer a laid back, easy sound. The kit won't change, but possibly Erich will add a $1 to the kit price and include this resistor for those who do want to do it. For those who don't, they can just throw it away.
You'll need a 10 watt, 10ohm resistor. This one works: http://www.parts-express.com/dayton-...sistor--004-10
In the schematic, you have a 3ohm resistor coming into the circuit from the amp. Don't change that. Then after the capacitor and inductor there is another 3ohm resistor that crosses the wires (trying to explain this simply). What you want to do is parallel that 3ohm resistor with the 10ohm resistor. Like this.
Sorry, I used a 2.7ohm in the example because I couldn't find a 3ohm on hand. But that's what parallel is.
Alternatively, if your XO board isn't accessable, you could connet this 10ohm resistor directely to the back of the compression driver. Kind of like this bad example:
If you like a forward, exciting, snappy sound, this isn't really for you. Especially if using an AT screen, you'd probably wanna keep it stock. Certainly worth playing around with if you're so inclined. Try both ways and see which you prefer. It'll only affect the treble, and it'll be a fairly slight change. Don't expect a massive amount of change.
Also, if you run autoeq of some kind, manual eq, use a treble knob, or anything of the sort, probably easier/better to just do it that way. This is only for those who like to run in Pure mode or don't have a way to eq. Which we didn't do at the GTG.
