Change to Horns or stay Dynamic

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 ;-)

even the largest horns cop out in the bass(falling back on a driver in a box), and in some cases the highs....

I read the review of the ATC. Has me very interested. All the recommendations here are excellent. But listening & time are the limitations.

In the end there seem to be few choices for ultimate dynamic capabilities outside of Horns. And yes, bass is an issue. But I do believe there are some great horns w. bass. I need to hear it myself. Most people don't have the room big enough to sustain bass in thier rooms properly.

Dave,

Dr. Geddes teamed up and went into a partnership with a music producer / sound engineer to manufacture and market pro-sound loudspeakers. The company, AI Audio is based and operates out of Thailand. The ESP15 is the Summa, using the same drivers as the original but with a somewhat different cabinet construction to save on costs. There are two other smaller speakers using 10" and 12" woofers that are just scaled down versions of the esp15. Sorry but I am really not sure on the availability of the Thailand products but the Summa is probably made to order. As per Dr. Geddes the specs of the esp15 shown on the AI website are the same as those for the Summa.

As for him exhibiting in any of the shows he has stated in the past that that is not going to happen. Only way to audition is in his home or possibly in one of the homes of the few owners of the Summa. He lives somewhere in Michigan and if I am ever close by I 'll certainly try to have an audition.

Here's another review:
