Setting amp output for speaker measuring

[Harry72]

How would I measure amp output in W so it can be set for say 1W, I want to measure drivers separately for xover design.
Do I need to measure and set at exactly 1W or can I just keep the amp setting the same for each test, does this effect software like Xsim?

Every search I try and do on the subject ends up at car audio guys level matching their amps or testing max output wattage.

Im not into electronic side of audio just speakers, equipment I have is a basic multimeter, DATS V3 and a Omnimic V2

Who said you have to measure at 1 watt?
You can measure at whatever level you like.
One watt can be quite loud and some tweeters may not like it without crossover.

Do you have REW?

 

[Harry72]

Have it now, I wasnt sure my Omnimic would work with it.

So keeping the amp output the same for all tests no need to measure?

 

[adason]

REW will tell you when the level is high enough.
In dB.

I like to measure between 80-90dB. No need to stress drivers above 100dB.
I suggest use protective cap for measuring tweeter (~20uF).

This is the lounge thread, nothing serious, just mish mash of covid builds. You can find some crossover optimization examples.

stay safe my friends!

here are some projects i am working on at home

first i got some old vifa midranges back from a friend, and I got small dayton amt to mate them with
vifa 13wh-00-08 is somewhat special midrange, free of the breakup grunge, even the ones i got are old, they still measure nice

here are some pics from the build, work in progress

may go active!
