GR Research NX-Extreme

Looks like a helluva lot of speaker for the money, even if you need to put it together which sounds kinds fun. Anyone built a pair of these or heard them?

Hello.
While I have not heard Danny's speakers yet (soon) I have heard some of his work. I have a pair of Emerald Physics EP 2.7 open baffle speakers that he build new crossovers for and they sound amazing! They use much higher quality parts than the original crossovers. I have the frequency response and waterfall graphs before and after and they are quite a bit better that stock. In fact I was told by Danny and one of EP's designers that they are likely the best sounding pair of EP speakers on the planet.
That said I am just starting to build Danny's latest speaker design, the new NX Studio monitor kit. Just received the kit and all the MDF, cherry veneer and grill cloth and stuff over last week and will start the build this weekend. Very excited about this. See it here: https://www.audiocircle.com/index.php?topic=160647.0
Also see this as to why you can build better speakers than you can buy in most cases: https://www.youtube.com/watch?v=7yozUh8xBfk&list=PLUFNGRKZZWXzCt2Syx4yjR4Oy7V-uiePB&index=19
I recommend subscribing to that channel and watching all the videos. Very educational.
Cheers.

I keep hearing about how the bass is good on these open baffle speakers but do not really pressurize the room the same way a box speaker does. Is it safe to assume that for rock they would not really give you that punch in the gut midbass?

I guess it depends on what you are looking for. I find the bass to sound very natural sounding and extremely dynamic, as if you were listening to acoustic instruments in the room. You can still feel the bass, but it's probably a bit closer to what you'd get from a high quality open back headphone (e.g. more sound than pressure).

Hope that helps.

There is a pretty noticeable difference between the Ottica's and Xtreme's and it's not just with the WAF as they stand 86 inches!! There is an added fullness to the sound from the additional 8 drivers that seems to be greater than the sum of 4 extra drivers, the fact that they barely break a sweat during large musical passages really helps define the inner detail that can sometimes get lost during increased spl's. There is also a deeper sound stage that also comes with having more drivers that can be quite addictive if you have the room to support them and in this regard the Ottica's are far easier to place within your average room. I own the first pair built, and my partner Jay and I build almost all of the flat packs sold, I run mine with a 4 stack of 12 inch GR subs and the combination will absolutely shock you with well recorded music. To give you another perspective, and i'm trying not to be too biased, I recently attended the Toronto Audio show, which I thought was excellent and the speakers that I felt had the closest signature to the Xtreme's, meaning with scale and size of presentation were from Grandinote, they were OBish line arrays and I believe that they cost 60K.

Hope that also helps,

Don

I believe my room is 13x16. Too small for the Xtremes?
