[Monsoon]

It was suggested in another thread, that the FPF-1000 midranges would have been better to be crossed over at a lower frequency, and I agree. I think 4k would make more sense.
But does anyone know if the tweeter will function properly at that frequency? (factory spec is 5k)

Also, does anyone have T/S specs for the midrange and tweeter?

Not sure which monsoon panels you are talking about.

With no extra baffle the 1000 panel goes to 1kHz, and they EQ it down to 250. The smaller one in the MH500s does not go as low, i am not sure how low they can be crossed (but 5k sounds about right, given what it is crossed to). I might even have one of the factory 2nd order XOs kicking around.

I'm referring to their floor standing home theater speakers.

They are the same 2 modules, but baffle mounted in an MTM arrangement.

but you're talking about the early monsoon computer speakers, and those had no upper crossover.
and my question is regarding the low end of the tweeter on the FPF-1000.

[planet10]

They will have the same response as the many i had thru here.

The big panel starts beaming earlier than the small ribbon, so going one step beyond multi-media what they used in the step-up home speaker is obvious.

Do note that Eastech bought Monsoon to ge the licence agreement, and there are improved versions of these drivers made. I have a couple of the ones aimed at replacing the smaller ones. They only go down to 5k but are smaller yet, and much better built.

Didtrotion in ribbons increases quickly if pushed too low. You might ve able to go 4k but it might require a stepper XO.

I'm very familiar with monsoon speakers, I have two pairs of the early panels with the wire frame, three sets of the planar 9 panels, and the FPF-1000's. I also bought 5 Planar 9 sets for my kids right around the time that monsoon went bust.

But I still don't get what this has to do with the low end of the tweeter.
obviously the mid panels can be crossed over lower. you could cross the upper frequency of them all the way down to 500hz if you wanted, although that of course would be useless.
But the low end of the tweeter needs to survive the extra bandwidth no matter what the frequency is.
I'm just trying to find out if it's safe to run them at 4k at full volume.

And it would also be nice if someone had the T/S specs for both the mids and the highs.

What does the exisitng XO look like?

My experience comes from 5 palletts of waranty returns after Monsoon was sold to Eastech. I went thru literally 100s of panels.
