Dave,

Here's a few links to reviews and impressions on the Summas:

To see what the speakers look like go to:

Hope this helps

Dave,

On the above links you will just gonna have to scroll down a bit to get to the posts that I am referring to. I agree that the site needs work if he is going to promote the product but Dr. Geddes is a scientist and an author and places more emphasis on the theoretical aspect of speaker design. He has said that he 'd rather license the technology than produce speakers himself.

AI Audio is/was his attempt to branch out into the pro audio arena and teamed up with a sound engineer/producer partner. The company is based in Thailand and it's not clear if production is ongoing and if any product is imported into the US. The Summas that have been sold in this country were made by the man himself in his own garage.

well live music is horrifically over amplified, so i am not surprised you would feel fatigue. Some speakers do "sing" a little more at higher volumes, but most good speakers will sound pretty good at both low and high volume within reason.

I am not up on all these new horn designs, but i worry about the usual horn issues of getting proper bass and placement. The planar camp deals with these issues too.

Thanks Manga. So, is the Summa a modified Ai???

Ai is from Asia and Summa is in the US, I think. That guy really needs to bring his site into focus. Like so many brilliant people he has trouble presenting what he's all about.

Will he be at RMAF this year?

Dgad,

It is funny how ATC & PMC have not been as successful in the US as other companies.

You need to hear one of their "ugly" three ways playing Sheffield Labs drum tracks in order to immediately understand why pros go for them. They are definitely overkill for most peoples requirements. PMC have better marketing than ATC as ATC rarely if ever advertise.

Incidently, an astrophycist that uses PMC recently handed in his PHD. So if you go "active" you will be joining a rarified crowd along with Mark Knopfler, Pink Floyd etc ;-)
