Radian LM10n planar driver and dspNexus

The LT3.2 was developed to be used with either a monopole or dipole radiation pattern. The standard setup is either with or without the waveguide. This would be for a sealed cabinet speaker as the rear wave from the tweeter is absorbed by material in the rear cup.
Dipole for open baffle operation gives a more spacious sound with a figure of 8 radiation pattern that I think works well in a room, but easier to keep side wall reflections down. Having diffusion behind the open baffle drivers adds to the ambience and gets rid of direct rear reflections that can interfere with imaging.
Fun stuff!

The best reflected (rear) wave diffusion is achieved with hemispherical diffusers. 2D diffusers Rob the soundstage of height.
Ergo: Mr. T ... thank you Trung. :thumb:

Hi Rich,
Fun stuff, indeed and thanks much for the explanation! I’ve not had any experience with OB, dipole, etc. Sure have led a sheltered (audio) life in some respects 🤷 Oh well…
I was fortunate to have the omni directional Shahinian Diapasons about 25 years ago. Would love to have them now just to compare with the quality equipment I have now. But those tweeters couldn’t compare to the wonderful AMT that I have now.
How does this tweeter rate as to some of your all time favorites?

Dave,
Thanks for the addition. Will most likely be getting Greg to make more of the Mr T's soon.
Nick,
I will be finding out about the LT3.2 as I get them into the baffle. If they surpass the BG NEO3-PDR tweeters in sound quality, they will be my new favorites. The LM10n planar mid has surpassed the BG NEO10's for me in their sound quality.
When Danny is smiling after a demo with just a pair of LM10n's and two 3x12 servo subs and we have both heard Line Force speakers in his old room, I know progress has been made. :)

Rich,
That is high praise indeed if Danny likes the sound and also your comments as you’ve heard so many good speakers over the years. I am quite curious how this comes out 😊
