GR Research NX-Extreme

I have GRs OB doubles but bought drivers for a third one. I wished I would have gotten the 8 ohm versions, for doubles. Then the 370 watt amp would have a little more push 370 @ 4, and half that at 8. So pick your drivers too. If you go trips, I think you have to use th 16 ohm drivers.
Doubles you use to have an option, 16 8 or 4, use to be anyways..

As for building them, just a snap, great workmanship and QC is outstanding.. Everything was dry fitted and marked.. Jays a great guy...,
The whole bunch had a LOT of patience, I ASK QUESTIONS, always a speedy response, very professional..

I had a pair of LS6s, man did they need breathing room. lots of room..
6-8 feet from back wall, no wall behind you worked the best, ampa style
sure a different speaker, the way they work, pretty picky, pretty cool if you get it right. lots and lots of room treatment..Same with most speakers..
I got them second hand, and the builder did a great job. I'd love a pair of LS9s oh yea...Much better tweeter section. I'd love to hear a pair...I think Danny uses a pair for reference in his builds.. Alu, frame. The new ones are HDF or MDF

Regards..

Oh, I neglected to comment on the 4 ohm version of the GR Research woofer. GR Research offers a 4 ohm woofer,

Yup there was an option or two. 8 or 16 ohm drivers 8 ohm drivers are louder, hows that? Also a sand filled DIY, too. There are some guys that will build the kits, finnish is always the spendy part. Emron, was a great paint, just the lead content was through the roof..and no breathing it at all.
We called it drop dead gorgeous, paint...
Jay the box and kit builder guy with GR, has the speakers the OP is referencing, (I think). he just loves um. Ask him, good guy.. Quality work from that guy...
