Open baffle speakers

@knotscott 

You mean something like this?

In application, very impressive.

I have owned planars, horns and box speakers. The OB speakers that have come through my room are the GR Research Super V, the Spatial Audio X3, and now the Qualio IQ. It is my opinion that the OB speakers image just as good as anything else I've owned and better than some. The key is having a space large enough to get them into the room and away from the wall behind them.

The thing I didn’t like about the X3 was Clayton’s decision to use a 12” driver to reproduce the midrange. I never got the feeling that the midrange reproduction seemed “real”. There was no texture to voices and instruments. Dynamics were good and the bass depth and quality was excellent. I kept them about a year and moved them on.

It’s been a while, so hard to compare. The midrange performance of the IQs is definitely top notch. The powered 15” drivers on the X3 might get the nod, but not by much. 

It seems that @bache has a habit of starting controversial threads about OB speakers. Not a good look for a manufacturer who builds a competitive design.

agree for 100% to produce bass 30 Hz baffle size must be HUGE

Disagree. The Spatial Audio X3 with it’s powered 15" woofer could easily reach into the mid 20s with a baffle width of about 18". For all it’s other shortcomings, bass response and quality was not one of them.

@ozzy62   Are you measure  or just listen ??

Both...

@bache 

You are just being obtuse now. You are on some weird mission to denigrate OB speakers for some unknown (not really) reason.

I understand how to take measurements with a Radio Shack SPL meter and test tones. And I know all about the correction factors for that meter.

I was born at night, but it wasn't last night.

 so base is not really an issue. 
 

That’s really cool. One question, how is the bass?
