Tyson's N1 Build (older brother of the NX-Bravo)
« on: 29 Nov 2024, 09:15 pm »
This is actually a gift.  A friend of mine (Heidi) is a music lover with a pretty decent CD Player and integrated amp (Acurus brand).  But downright mediocre speakers (Anthony Gallo Micros). 

Why the N1 and not the NX-Bravo?  Pure chance.  After I built out my LineForce arrays, I was looking at the backup tweeters I had for my old Super 7's, which were in a box in the garage and I hadn't looked at in 6 years.  I open the box and see one of the unicorns.  A pair of deep back cup Neo3 tweeters!!!  So I reach out to Danny to see if he can help me put these unicorns to good use. 

He says it'll work perfectly for the old N1 kit, and not only that, the new NX-Bravo flat pack will fit the old tweeter, no problem.  I buy the flat pack, the M130 5.5" woofer and various caps/inductors/resistors, plus hookup wire. 

This time I decide I want to learn how to veneer a speaker, so I buy some nice blond ash veneer, paper backed, some heatlock veneer glue and various tools to do the veneering work.  I thought veneering would be easier than painting, but I was wrong, hahaha. 

Veneer stuff all from here - https://www.veneersupplies.com/

I watched Peter's youtube videos on veneering the X-LS (also with rounded edges).  It was enormously helpful.  Video is here - X-LS Speaker Cabinet Wood Veneering .


All needed parts:




Assembling the crossover:




Very nice flat pack!




A friend of mine has a router table so he did the roundovers on the front and back of the speaker.  Thanks Mike!




Beautiful rounded edges:





Ash veneer arrives.  This is pretty thick veneer.  It ends up looking really nice in the end, but it was really hard to work with.  Next time I'll use a thinner veneer.





Heat glue.  I had a little left over after this project but not much. 





Helpful tools for making the cut lines:





Final cut lines.  I found regular scissors were fine for actually cutting everything.  Since most edges were oversized and would be trimmed down by the router, no need to be super precise with cuts here:





All cut:






Speaker covered in heatlock glue.  You can't see it, but the paper-backed veneer is also coated with heatlock glue.  Time to iron!





Veneering done, time to put in the crossover and wire up the drivers, hammer in the port and the tube connectors:






All done:












The back is the one place I made a mistake.  The veneer was so damn thick, I wasn't able to get through it with a single cut with a new razor blade.  As I said before, next time I'll use a thinner veneer and that should make this part a lot easier:




After assembly I took another week to really fine tune the speakers and dial them in so they went from 'very good' to 'outstanding' sound.  I was really happy with them.  If I ever am forced to sell my giant speakers, I could very easily live with this speaker.  I imagine the NX-Bravo is even better. 

This past Tuesday I took it by Heidi's and hooked everything up.  She's older and on a fixed income and could never afford a pair of speakers at this level of quality, and she was absolutely gobsmacked after we got them installed in her system.  Her reaction was "I've listened to this CD hundreds of times but I have NEVER heard the music before now!".  That made me feel pretty good  8)

Early B.

They look nice. Wondering if any of the GR offerings are good for near field listening. I found you can get really good sound much easier and cheaper with a near field set up.

Looks great Tyson. And for a first attempt at veneer they turned out really nice. Most importantly I'm sure they sound fantastic. 8)

Thanks!  It took about a month of work (mostly in my free time) but it was worth it.

Yes, the LGK 2.1 is great for near field listening.  I built a pair for my son's computer setup and they are perfect for that.

Yes, tuning the speakers was a challenge, but also fun.  To keep costs down, I was trying to re-use parts from my parts bin.  So Sonicaps in the tweeter circuit and Clarity Cap MR's in the midrange circuit.  Sonicaps I find a bit analytical and Clarity Caps I find a bit sterile (which is why they were in my used parts bin, lol).  Luckily I also had a pair of very rich sounding Jupiter bypass caps in my parts bin, which mated really well with the Sonicaps.  For the Clarity Caps I had some old Russian KZK K78-34 paper in oil caps I'd pulled from a tube amp a while back (also very rich sounding).  In the end it came out very well - a nice balance of details plus richness of tone.

Hey Tyson,  are you familiar with the sound of the JB poly caps Danny uses now?  I’ve been wondering how they compare to sonicaps and clarity.

I am, they're pretty good.   Probably better than the caps they used to use for really large values (I forget the brand).

ERSE was the previous one.

That's right.   Erse was fine, but the JB's are a bit better.

I agree. I use the 2.1’s on my office desk. They sound great. Just add in small stands to get them raised off the desk a bit. Last tie. I used the small stands flat pack on the gr site but most any other stands could probably work.

Nice build Tyson! I love the veneer, I like the natural light finish. Well done!

Looking good, Tyson!
 FWIW, I suspect the veneer thickness is not the culprit, but the backing. Stiffer and thicker stuff is usually used in architectural type of installations rather than furniture. It seems counterintuitive, but the actual wood layer thickness is typically the same.

Maybe so.  The paper backing on the veneer was also hard to trim because it was sticking out around the edges even after routing and sanding.  Maybe it was the paper backing.
