You were there???

this is great...er, yeh, sittin' in one of the judges chairs :D

I do look forward to reading the comment sheets. They are a work in progress. It is the journey and the effect we have on others as we pass. ;)

craftsmanship and imaging

There is this thing about imaging. The toe-in I chose was questioned by another in attendance. I took the implication to be that it was extreme. Now I have this feedback that it was to some benefit...

On the ride home I thought about this: how little I know...

I envision a way to explore this "imaging" thing.

turntables, lazy susan bearings under round platforms for each speaker...both speakers facing the back wall @ initial set-up...a rope around both platforms,attached to them, crossed into a figure eight when viewed from above...with a tag line allowing the speakers to be rotated from the listening position...the figure eight makes the speakers toe-in together or toe-out together. listen or measure...learn

Thanks to all for the comments, even the ones I have yet to hear. Bring 'em

Anyone got a full pic of the pair painted like 'Ole' Glory'?

Re: Pictures from Dayton 2010

Here is Shawn's






and Ole Glory


Ed L. I would have liked to hear a bit different music thru your speakers. Plus be able listen longer!

Re: Pictures from Dayton 2010

Sweet! Thanks! Are those the 10" Genelecs that were on BO a while back?

ttan98,

<$200 is a bipole?

Yes, they are my MLTL bipolar speakers. I used CSS FR125S drivers (actually in my case FR125S and WR125S front and back). You can add a rear mounted super tweeter for a little more treble fill in the upper octave if you wish.

Re: Pictures from Dayton 2010

I agree on the music selection. The first set was good, the others of not much use. But the other 2 judges liked them better, so we went on with them. I almost asked to got back to the first set, wish now that I had. :(

As others have mentioned above, the second two sets really didn't test the bigger speakers.

First set, first song - was from the soundtrack "Oh Brother Where Art Thou?" Alison Krause and choir singing "Down to the River to Pray." I didn't choose it, but was glad it was included because it's been a favorite test track of mine for years. I've hauled it around to a lot of shows. Very subtle and shows even the slightest changes in a system.

Yes, I do get around to a lot of audio shows and hear a LOT of speakers. RMAF, LSAF, the SHOW, CES, Puget Sound speaker contest, Capital Audiofest, Montreal, Dave D's Vancouver Island bash, etc. The speakers at the P.E. show where easily the equal or better than 90% of the commercial products I hear.

The Planar speakers were remarkable. So clean! I didn't want to stop listening. He said they went down to 80Hz, but it sounded lower. Didn't get a chance to talk to him. Hope to hear more from him in the future. I'd own a pair.

Shawns' were very nice (SP25). Maybe the only pair where the tweeter could actually have come up a bit. Nice work.

Unthinkable but with constant directivity, it expands the image rendition zone -- for those listening off center, the phantom image is stabilized at the center location. It must really be heard to be appreciated. The concept dates back to the 50's, actually; these modern designs allow this to be easily achieved.

I've been considering setting up the figure-8 variable toe-in rig myself. In theory, we should be able to balance the trade-off between imaging and spaciousness for any given listening space and listening distance via that adjustment. Studies indicate we'll initially favor spaciousness, even at the sacrifice of spectral and spatial accuracy, but over time, will dial back the room influence in favor of the latter, with recognition that the sameness of artificial spaciousness with all program material, while pleasurable, grows somewhat oppressive over time.... :rolleyes:

Re: Pictures from Dayton 2010

Congratulations to Dan (and Paul Kittinger (?) for his Transmission Line design for the RSS265)!

Dan's got a thread over at HTGuide on the Blades. However I'm not claiming the crossover design posted there was the one he presented at the DIY.

I only wish New Zealand was closer. It would be great to attend, meet and learn.

Congrats, for building an excellent sounding speakers for such a small amount of outlay. Not easy to achieve.

I heard about your speakers from another forum, I think you should publish the design of your speakers, I believe many enthusiasts would be interested in building them.

Cheers.
