GRS 10" planar mid

[rpb]

I don't want to be misled by the specs, or general overview. Would this driver be suitable for use crossed at 400hz? What about 800hz?

Only way to know in my opinion is to buy one and listen to it in your room with your typical volume levels.

It does have a surface area larger than an RS180 or PM180, but probably very little X axis travel. There is a very small impedance bump around 200 hertz, not sure how that would affect the sound.

No fs specified but assume it's around the 200hz mark. The frequency response is, well, interesting to say the least. Huge dip at 500 hz, might be better suited to the higher crossover point perhaps crossing to a small woofer with a shallow lowpass?

Not sure if you're specifically looking to work with a planar or not, but I'd suggest the SB Acoustics MD60N-6 would be a better midrange to work with crossed at that 800hz point.

They list 200 to 8k as the usable range, and 70w power handling. Sounds too good to be true. I'd like to know if it can even handle a 400hz x-over point with as much output as a good tweeter.

I'm trying to come up with a design with limited vertical response. There's no information in the specs about vertical off-axis, but I'd assume it falls off considerably.

After a closer look at the specs, I see that the horizontal off axis is not what I need, so it's not going to work for this design.

I almost completely ignore usable range specs as they tend to be highly exaggerated and misleading.

That planar, as far as I know, is a remake of the B&G Neo10 and may include some "upgrades" specced by Danny Richie. The Neo10 was quite the mid and performed well past expectations and specs would lead one to believe. It might be useful to search for discussions related to the Neo10 to gather insight into what this thing can potentially do, along with its limitations - such as baffle dimensions, or the lack there of and the debate between enclosing the back of it or leaving it to play in dipole.

An example to read up on would be Dan Neubecker's Echelon project. I believe he crossed the Neo10 at 325 and 2100Hz and he ran it open back.
