Has anyone used these or head them?

Any idea on crossover points?

they look like they will model well in a nice small 20ish Litre box with bass down into the low 50's, high efficiency and i read somewhere that the compression drivers were OEM's by Radian....:confused:

expensive @ around £500 a pair though... :xeye:

Thanks :)

I see what you mean, -10dB@50Hz.
Yes, I always find them a little overpriced for COAXs.

That would make a great midrange >150Hz or so in a sealed box.

From the pictures, the construction looks very P Audio.

Edit: still haven't heard back from Hemp with the questions and additinal data I asked for.

The FR data on that sheet can't be correct. The sheet says 50Hz Fs, but on the FR graph the resonant point is clearly 80Hz.

Hemp Acoustics...

although growing (pardon the pun, couldn't resist), is still a small operation and Perry pretty much answers email himself. So be patient.

I used WINlsd pro alpha and ended up with something completely different. Vas = 95 litres? I do own the newest version of the Hemp FR8C, but it is not as efficient, not a co-ax. The FR8Cs work nicely in a 20 litre box (see Hemp Acoustic site). That's what I listen to them in and the JE Labs OB modified.

I've been looking at thesefor a while, I might use these the mids/high range in a dipole design I've been working on for the past month or so. 2 15" dipole subs would be used for the lowend. Not sure if I'm ready to spent the $$$ i might try the FR8's and see how they work at 1/4 of the cost. I'm kinda waiting on some more feed back about the driver.
