Don, true.  6 of them in a line array fixes that issue.  But probably not feasible for most. 

Although the approach outlined here of only using the planars for upper mids and dynamic drivers for lower mids sounds promising!

~$700 for two LM10N drivers currently from Radian (just to add pricing context for historical relevance) 😇.

One can buy the GRS slim 8" for $53 and line-array seven of them for the price of one Radian 10.
People have given up on these GRS planars?

This is been discussed in other threads and Danny has measured them and they are horrible. You get what you pay for.

Tyson, it certainly helps!! Actually I was at Jaytors for a session a couple months back, the 3rd set of Lineforces I was able to hear, and they sounded great as always, wonder how they sound now with his fancy new pre-amp? I know my buddy David has some LF’s with the GRS 10’s, David, how do they sound??

Here is the GRS10 vs the BG Neo 10 in the Supermini frame. The Radian LM10N measures even better than the Neo10 did.

I was planning my next speaker build for my 2 channel living room system.  I saw this project and would love to work with everyone to build a passive speaker using neo3, radian 10 and some gr 6” drivers maybe even paired with some 8” servos on a rythmik plate amp.  Then add in a double trouble pair behind.  That would be fun.

[Huskerbryce]

Danny is probably super busy but if he wanted to tinker with hobbs on a crossover I would be down to build these.  Would need to figure out a cabinet design for Mike to fabricate.  🎶

[mkrawcz]

Danny is actually working on this with me. He has the prototype m165 stands for these speakers already. If all goes well, I’m sure it wouldn’t be too difficult to get the flat packs from Endo2112 and Captainhemo for the Superminis and the stands.

[Huskerbryce]

I am very intrigued.  When I set out to build the NX oticas last year I really wanted to build the super 7 but was bummed to find out that the parts are scarce.  I looked into the Radian drivers but settled on just building the Otica and I love them.  Im wanting to put together a 2 channel system for my living room and really want to use planar drivers for the highs and mids. This project looks exactly like what I am looking for.  I will be following the progress closely.

For the Line Force, the Radian LM10n would be a better replacement than the GRS NEO10.  I did not have good luck in testing the GRS NEO10 driver in the Super Mini style open baffle.

On the other hand, the 6xLM10n's in an open baffle line array using a dspNexus 2/8 as the DSP crossover and speaker voicing worked extremely well!

The two 6x12's are the modular 1x12's from captainhemo with SW-12-16FR drivers and 4xHX300OB12 servo amps.

Tyson, unless one prioritizes dynamics as planar’s don’t move air, not saying I don’t like their seductive sound. There’s just a snap that missing in the range that I previously mentioned, the issue is how important is that to you, and your listening experience.

Putting a 10" midwoofer in a sealed box along with the Neo3 and Radian 10 in OB mode might add the dynamics back in. Plus, this option would be easy to DIY with a flatpack for the top section. Set these "monitors" on top of double troubles, and you'll have a world-class speaker.

[Endo2112]

Except for tweeter height, there is no free lunch with speaker design!!

The tweeter height would be easily adjustable by tilting the top cabinet to ear level, if necessary.

My modular speakers are 61" tall with the tweeter on top. I've tilted the tweeters to ear height, but I prefer them to be level because they seem to fill the room better. Besides, designing speakers to be at ear level isn't practical because there are too many factors to consider -- namely seat height and the height of the listener. Music should fill the room, not be targeted at your ear. Line arrays do this well. Understandably, speaker designers would disagree because they aren't designing speakers for specific rooms, so they need a consistent, theoretical point of reference.   

[Endo2112]

True, but if memory serves me correctly the lower section has offset drivers so the cabinet is shorter.

Been thinking about these speakers a lot lately and am seriously intrigued by their use as a mono output center channel for use in a large desktop application. I would love to build one but am absolutely gobsmacked when it would come to building the cabinet. Imagine it'd be the same but without wings on either side, or something. Either way, I bet it would be pretty slick in effect. I wish I could build it just to see!! Very cool. Maybe I'm nuts.

You’re maybe just nuts you say?

Well, I think you’re in some pretty good company here then!
