Just follow my 3-way x-over frequency.
Woofer TAD1601 20~400Hz.
Mid Altec288B 400~7KHz.
Tweeter Jensen RP-302 over 7Khz.

Great!
have you modified the gain with measurement?
Unfortunately, We could not visit your blog in Taiwan (by net-control ?).
If possible, could you post your highlight project to mainland Loadspeaker-Diyer : ÒôÏäDIYÂÛ̳ - HIFIDIYÂÛ̳ - Powered by Discuz!

Plasma speakers are awesome!
Listening to a system with a plasma speaker is simply awesome.
My friends system utilizes a Hill Plasma that goes down to (700 hz)
in conjunction with Apogee ribbon speakers!
No ozone with this speaker as it utilizes helium which prevents ozone
from becoming an issue.

A friend at Bell Labs (around 1969) had all the tech resources in the world and he had AR3s (sealed boxes, very good sound for the time) with Ionovac (or Dukane, I lose track of who owned the brand) tweeters sitting on top. Fantastic is not an exaggeration. All the music seems to come from the blue glow (which may have something to do with the listening experience).
I can picture the session in my mind today.
I think people under-rate the need for tweeter power. You can get it with a plasma tweeter but there are other ways too, with multiple tweeters.
(I had another Bell Labs friend who built a large house around his Klipschorns. I'd rank the Ionovac system higher, except for bone-shaking ability.)

Hi Carlp:
You will see it happen asap.
After test Plasma midrange play sound @60 hz is ok.
If you can get 300hz to 350hz at 105db at 1 meter, I would be very happy to see this !!!

Hi Jer:
300~350hz is narrow.narrow band.
Are your sure? what for?
Aster
No, I meant down to 300hz to 350hz and up to 20kHz of course.
The lowest frequency's are the hardest to produce as they require more displacement the lower you go.
To do this would require a lot of power!
I saw an example on 4hv.org that used a ceramic type transmitting tube.
From the video the flame was huge and was quite loud!
Very clean sounding when it wasn't clipping the audio.
I tried to search for it today but the site wouldn't let me sign in for some reason so it will take me some time to get that straightened out.
It was quite an impressive video.
