Hemp CO8V Coaxial

inrank · 13th August 2007, 11:27 AM

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....

expensive @ around £500 a pair though...

Thanks

Have a look at the hemp FR graphs and the equivalent Radian; the same.
I've asked some questions to HA and am awaiting a response. They look good, potentially......

yes, but i dont think it would work in a small 20L odd enclosure

thanks though

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

Check also (Vas=17L/95dBs SPL sharp) BEYMA 8XC20 coaxial loudspeaker and about the same size.
Note: bass-reflex cabinet, Vb=20 l, fb=62 Hz

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.

All of the graphs for the Hemp coaxials were obviously taken from Radian. I noticed this a long time ago.
The Radian coaxials seem about the same, for half the price. Take your pick.
