Tweeter question.

[Phoenix Risen 10+ year member]

any suggestions on 4 nice tweets to match up with my 4 mpyre M65 mids.

there will be a pair in each a pillar and will be running on a sax 100.2/125.2 so around 200 rms per pair.

What do you like in a tweeter? Metal domes or textile/silk domes? and budget

ive got dd t2's now and i love them. so part of me wants to just get another set of them and call it a day.

but i also want to try something new.

and i usually prefer silks. i just like the smoothness.

If you can dial it down and give yourself some head room check out the LPG 25NFA's or the 26NA's. The NFA's are a silk, the NA's are aluminum, but neither are harsh.

You can also look at the Seas Prestige 27TFFNC/G or SEAS Prestige 27TAFNC/G.

my deck has 6.5v preouts so i cant really dial things down since the sax 100.2/125.2 are 6v input.

The math involved is this:

Voltage = SQRT (Power x Ohms)

From there the power is the speakers RMS rating and the ohms is the speakers ohm rating.

V=SQRT(80x8)

V=SQRT(640)

V=25.29

If you put a DMM on the speaker wire outputs and tune the gain dial you should get as close to 25.29 volts as you can. That will match the power of the amp to the speaker RMS. The above example I did with the LPG 26NA.

his amp is most likely a gain input of 6v - 0.2v. which means that his amp is running a full load when the gain is all the way down. his only way of cutting it back would be if he could cut his voltage in half or something

He has to dial down the gains which I just showed you with math.

and i understand that but the purpose of setting your gain is to match the amps level input (gain) to your preout voltage. his preout voltage and the minimum amp level are both 6v, so he cant physically turn the knob below it's minimum point. his only way of adjusting it is if he adjusted his preout voltage

He can though. Adjusting the gain adjusts the voltage. The amp is rated down to a .2v input. Its perfectly acceptable to dial it down.

im confused, wouldnt turning your gain down to a lower value (closer to .2v than 6v) cause overpowering/clipping? and adusting the gain doesnt adjust the preout voltage it adjusts how sensitive it is to input

Ever tuned your amp via DMM? Thats exactly what the math does that I showed you.

This is a good read.

i have set multiple amps with a dmm it just doesnt make much sense to me that turning the gain knob "up" results in a smaller amount of output, because whenever i raise the gain the voltage always rises
