Title: Hard own modification NFX speakers, DIY made.
Post by Piccaso on 12/13/21 at 16:35:07

Hi guys. You can accept this topic just as selfish topic, or what ever you like... :) Before i made by original plans model ZOB with SEAS full range premium driver, softly modifited. After, when i saw this model - NFX - i got idea to make something like them. And because i didn´t find or get any informations or answers for my askings, i decided go for risc. And build them as my own creation and project. I made realy hard modification, especialy inside. Use Li Audio Silver 8 driver plus high tweeter. There is 2 and half rooms inside, with helmholtz rezonator similar as on the ZOB. On the end, open lines on the both sites are for more than half closed. 2 months building, including 2 weeks sound tuning...uff... Result is - two times wider and deeper soundstage than ZOB, almost two times faster, bass is crazy punchy and start cca from 40Hz, but very fast. Very transparent, timbre and decai is very real. Symphonic orchester come in my room with his size and informations about all artist. From ZOB it was juming to different level. My big troubles during building and tuning were definitely gone and result is full satisfaction. Any way, for sure these will be on the world only one from one pair. Who created it like that must be stupid - it´s me.... :) And as i said, even idea is from NFX, they are totaly different, and this my topic is only for something like motivation or idea for some one, make his own special speakers with base from NFX. Just be ready - nothing is easy on that... :)

And last one photo. Plus, here is link on youtube, for very very very simple and basic impresion. I made recording just with my cell phone by hands, and only after cca 20 hours burning. This driver need definitely minimum 100 hours burning. https://www.youtube.com/watch?v=77362VwXUs0&t=589s

Beautiful! I couldn't appreciate their sound since they only sounded as good as my crappy computer speakers. I think grill off looks fantastic.

Thanks Archie. I try did my best. On these bixes i have to do everything with my hands, except front and rear wood panels. No any painter want paint me them... :) On teak finishing i used wax oil. Is beter than laquere. High tweeter is only for extension to cca 25khz, even i can't hear it any more... :) Sound impresion - i recomend you use some good headphones. Even sound still will be only half of their real presentantion. With tube amp (we try 15w small amp), sound is famous fluidy... Li Audio drivers must be dumped for cca 3-4db on high frequencies, they are very present. But musn't be dumped more, because than they start resonated, be extrenly bassy... I try them also on ZOB cabinet. Is usable, faster than SEAS PREMIUM, tonality more dry, but for their transparency sound was as from laboratory - extremly detailed and sharp on highst. Thanks....
