Actually it's my experience that an OB can be too big. I spent
quite a bit of time with my 6' high x 4' wide baffles and concluded that
they were too big. Cutting them down to 5' X 4' was a real improvement.

I think at least part of that is due to the ability to access more of the
rear wave's "illumination" of the back wall and reduced standing waves
between the baffle and the wall.

Hey Nelson,
I had the pleasure of hearing your room at RMAF in '07 and I was really happy when I left your room. a real pleasure to listen to music in there, musical and chill . Again in '08, I was just loving your OB's but even better was meeting Colin and his generous expertise and sharing of info. Please thank him.
Do you plan to bring the Feastrex OB this year to RMAF? or maybe burning amp? Love to hear them...

Thanks. We'll be there again. As we display with Lowther America,
you will not be surprised if Feastrex is not featured in our display.



Burning Amp we might be able to manage.

Nelson, ask Jon to also bring his Lowther drivers treated with the EnABLe treatment. It is well worth the listen.

Hi

Compared with Lowther PM6A what is the major difference in sound?
And how much better are they? It is 5 times the price.

OK guys, Mr. Pass has well earned his success and I marvel at his products, but I have yet to hear a speaker with a whizzer cone, at any price, that sounds as good as a high quality dome properly matched to a good 6 or 8 inch driver. No that I have given up on full range, at age 73, I am still experimenting, seeking that grail of single driver sound. Mr. Pass let us know your results with the new drivers.

Interesting question.
I have played with Fostex FE206EN several times and was never disappointed by listening tests.
Compared with this model what is in this case the major difference in sound ?

Hi Nelson,

Wonder if you are still favoring open baffles.

I have a couple of questions.

1) Did you consider / experiment with different baffle materials ?

I got a good result with a laminate of 1/2" MDF bonded with PVA to 3/4" concrete. This was my best baffle to date but I think 10mm Aluminum bonded to MDF or birch ply would also be a very good candidate. Bonding two dissimilar material seems to substantially cancel each of their resonances.

2) All OB speakers I have seen have the speaker placed centrally on the baffle but when experimenting with "edge" software it seems to me that the best arrangement is having the driver close to one edge and then adjusted vertically for the most linear response. But no one seems to do this - did I miss something ?

cheers

mike
