Alright. You may have to stop here first. AJ from Soundfield Audio was here last weekend and we speaker geek'd all day. He brought his prototype 1812 to compare in my room. I keep forgetting to check your thread because I generally stay clear of the fullrange forum.

I assume you've seen VV's thread about the dipole desktops?

Are you talking about gainphile?
These?
Gainphile: S11 OB - Desktop Open Baffle with Seas 8" and Tangband Full-range
I've always wanted to try this method of soaking up the rear wave with foam and let the dipole cancellation do it's job.
Everybody is hot on SL's and John k's offerings so I thought it was time to give this one a go...and I already have the drivers, wood and the mini-dsp so it's a free build

I'm not sure I can bring that 7 1/2' tall speaker to orlando. My flat bed truck is out of gas

Here:

]OB for nearfield PC listening

I thought he stopped by DIY sometime too, but it all runs together after a while.

No need for a flatbed, just for checking out my system and over at the studio.

Definitely, I will come by.
But I want you to listen to Ambiophonics on a reference system.
So, pretty soon

Hi guys

The design outlined in the first post, is that not rather more cardioid than pure open baffle. I have to say I like, because I have been comtemplating something exactly like that. My idea was simply to reduce rear radiation so that it can fit near a wall.

Hey Deon, I hear what your saying but I'm not trying to get a cardioid response, I'm just going to try and attenuate the beaming rear frequencies, the ones that wouldn't make it around the baffle anyhow.
I still want the dipole null at the sides.

If that's what you were saying. Now that I look at your reply again, maybe you weren't saying it was a cardioid.
I don't know, I can't tell

For a quick trial, simply keeping the nude drivers upright (by some support under the magnet) and facing you on the desk, you're ready to go.

Within the reach of an arm, you'll be suprised how good they sound in such a simple way. Of course EQ is needed, but compared to far field listening, the bass response in such a near distance would be acceptable under much less EQ. And, you'll probably forget those problems about dipole, cardioid, null... etc and enjoy the music, hehe... I did.

Have fun

interesting Melo! I actually have the RS100, good driver. I use them in my watsons that now are becoming my desktop speakers. I kept the pipes. Will follow your progress closely.

Yeah, I'm the naughty boy over there for using fullrangers in multiples and implementing DSP instead of passives

I wish I could have posted my last few builds on this side, they may have caught more interest
