Anybody heard of GEKKO speakers?

It's flat speakers like Magnepan I guess.

I'm looking for not so expensive on-wall speakers as a secondary system. Looks good and price is great,too.

I don't see much of information about this product and it's not even listed in Bluebook secion from Audiogon.

They are 4ohm speakers and I'm thinking about matching it with NAD T743 which is 4/8 ohm receiver.
Sure and I've hear them, too. Only once, mercifully.
I just saved a bunch of money on my car insurance by switching to GEKKO!
Ha Ha. Just kidding!
Look in the audio mags they are advertised frequently there. Dalton you took the wind right out of my sails.
I used to sell them or tried to. great waf but they suck. Amazingly I disliked the highs the most. You'd think that would be the best part. the highs just didn't exist.
You can get two for 150 bucks now (orig 500), lots of hype about these in the late 1990s...

good luck
