Opinions on GR Research NX-Studio

[Evo-No-Revo]

Does RoomPerfect show you what your before and after in room measurements look like?

No but I played around with REW after my first time to set it up...what a pain but it looked moderately better but it sounded way better. I know that isn't much help. It is simple and effective and I really just lost interest in chasing my tail for some ethereal or measured improvement. A few more room treatments and I am pretty much done. I have been a fan of Lyngdorf for years. I have had like 5 pieces. TDAI-3400 x 2 + 2200 + 2170 and MP-50. They are my goto when I get sick of chasing and want to go integrated.
I understand about the measurement thing around these parts... But I have had some of my best audio experiences with tubes and TTs....for whatever that's worth. The emotion in the music is what I seek now. Often it takes a little alcohol to get truly get there! The NX-Studio can take me there to bring it back to the subject.

Yeah TADs definitely a different price league but was making a point of reference for vague comparisons.

Thoughts?

Thanks

So are you thinking of buying these or just curious? Just ignore these people that constantly trash GR Research, they have no experience hearing these and won’t consider anything from GR Research regardless of how well they perform in real world subjective listening.

Though if you build them yourself, they probably would be harder to sell if you decided to upgrade to something else.

Why? It's not without cause or reason... look into it.

The right way to think about it is the enjoyment of measurements around these parts *and* having the best audio experiences with tubes and turntables…

Take a look at my 300B SET review and comments on the LXV-OT10.

I don’t have the 300B SET anymore, but I still use the LXV-OT10.

I know all about it. It almost stopped me from buying the rest of the kit to build my speakers. But I decided that there always was and will be two sides in this hobby, I’m sort in the middle, took a gamble and it paid off.

I definitely get that and agree.

I think they NX-Studio are harder to sell than a regular prebuilt speaker. I put mine up for sale for a bit because the addiction was hitting me again. I wanted to try something else but not for a good reason. So I took them off the market. I did get some response but no one came through before I pulled the ad. It was for about one month or so. I am glad I didn't sell them.

I think the two GR-Research ads I linked are more about the guys don't want to ship is why they have been for sale for so long. At least the NX-Otica. Plus the economy.

But I think a lot of the GR-Research crowd has become smitten with the two new Old School Series the Brute and the Bully. So a lot of the potential interested buyers are looking at those as projects. I know I am interested but I know I would loose the soundstage and separation I get with the NX-Studio and the open baffle tweeter. Plus the whole build time thing is of no interest at this point.

Since you would need to try and source the right size boxes or crates and figure out a safe packaging scheme, it wouldn’t be too much fun to ship them. Plus sorta heavy and large. The NX-Extreme would be complete nightmare.

Those old school models are nice since there’s no need for separate subs, but the higher quality drivers used in the NX series I think makes a good improvement to the overall sound quality. A more refined, transparent and accurate sound.

You're in the middle? So you support scams but only just a little bit? What does this even mean?

Boy you can really just make anything and slap the word "reference monitor" on it. Not really anything monitor worthy about the NX Studio, the data set on the GR research site is bad. I mean that both in how it's presented and how the speaker performs. Why is the on axis responses between the graphs so different? They shouldn't look that different if you measure the speaker right and stick to one data set for hor and ver. Why can't he share the lower response of the speaker? Does he not know how to do a close mic measurement of the woofer and apply diffraction sim and merge with far field? Where's his reverse null? Spin or polars? It doesn't look like the waveguide was designed correctly, also why even have a waveguide for the front radiation but not for the back and track the wave in a box, isn't the point of open baffle

OP if you want to DIY a monitor grade speaker this is the quality of data you should expect, and performance of similar calibur. Danny is just so far behind the times and a fairly average speaker designer.

Well I think there’s enough feedback from different perspectives to help the OP make a decision.

Good luck and hopefully you enjoy whatever you choose. I just gave an opinion that’s apparently not worth much here. So no need for me to post anything else or engage in some kind of debate about GR Research.

I disagree a bit Same NX-Oticas were purchased by seller from original DIYer for cheaper price HERE

The original DIYer is still looking for a buyer for his GR Research Subwoofers stacks.

I looked at those, but doesn’t include the amps and no shipping. I built modular subs. Easier to move and can add another sub or two in the future.

Probably a similar feeling some members get when they see posts like this.

Horizontal directivity looks messy above 3k. And for an open baffle that small I wonder how the low end performs. Unfortunately, the published graphs start at 200Hz (and there's no distortion graph) ...

Agree wholeheartedly, notably the distortion graph. I like the BG tweeter but not as an open back and definitely not crossed as low as Danny does. For the OP, respected designer John Krutke tested the tweeter and here is what he stated...

"This B&G tweeter outperformed everything here, in most cases by a large margin. Response curve is ok, but nonlinear distortion is excellent. This is a very clean and natural sounding tweeter. Note: these were tested with the rear chamber in place. Later, with a different pair, I also tested with the chamber removed. The tweeter was far too overdamped in that case, and I recommend leaving the rear chamber installed."

Krutke is no longer active but PS Audio uses the same tweeter tech in its Aspen series and their designer @Chris Brunhaver knows it well.

Hope this helps!

I'll give you six months off so we can all avoid that feeling.

Just to add, as fas as I understand, the GR NEO tweeters used in open baffle are modified for that purpose. Using an original BG one wouldn’t work the same. They sound really good in open baffle configurations.

This is your assumption, as far as I know, the only modification is to remove the back.

Proof would be if Danny showed distortion measurements for the driver AND the finished speaker. As it stands, his website does not even offer specs or measurements at all for his version of the BG Neo3. I understand you are invested in your purchase, but there are certain accepted industry standards and GR does not meet or barely meets them.

I also note that his latest NX speaker uses the deep back cup.

The waveguide allows crossing the tweeter lower, I remember he mentioned that in one the YouTube videos. If it increases the distortion, I guess it’s a trade off he felt was worth it through subjective listening. From what I understand it’s hard to get a meaningful distortion measurement without the proper facilities. I got different readings on different occasions when I use REW, some distortion readings looked good some not as good but within reason considering speakers cause the most distortion.
