Up for grabs is this TREMENDOUS sounding 12" AlNiCo+ brass sleeve + hemp fiber cone speaker...

AlNiCo+ brass+ hemp= fat, thick, meaty tonality... AAAND_ when you use the special 12 gram, neck dipped proprietary HEMPOPOTAMUS cone assembly, you also get speed, resolution, accuracy, and a well balanced midrange and top end that is even BETTER than the usual HEMP-O!

Its a SIXTEEN OHM / 16 Ohm unit, and around the 30 watt range.

This unit was completely re-fabricated at PMR in Ohio with all new OEM/ AMERICAN made components.

There are no after market, replacement, or import Chyna crap in it , but ONLY AMERICAN made parts....

.......'fellas', even if you don't buy from me- BUY AMERICAN!

This 1940s gem was stripped down to bare metal and magnet, and then EVERYTHING was replaced. ...From the inside out, it's basically a new speaker again- ONLY BETTER!

The magnetic gap was verified with a gauss/flux probe and measured just fine, so it was PURPOSELY NOT de-magnetized/ re-magnetized...Some people say these old OEM magnetic assemblies "sweeten with age", and after I heard it, I HAVE to agree!!!

The frame was stripped down, and then shot with fresh paint to look as good as it sounds...

The original terminals were retained, so that you have the industry standard spade terminal hook ups..

Then- EVERYTHING from the inside out is all new components.... I'll itemize:

*Front gaskets- I found a good pair of OLD OEM natural repressed tan paper gaskets, so I used those to look period correct.

*Litz wires-- these are COPPER lit wires... After measuring the industry standard silver/gray "pot-metal" woven conductors, I now use COPPER on ALL of my rebuilds, new units , and customer's repairs. That gray stuff does nothing but smudge and smear the signal BEFORE it even gets to your voice coil.. By using copper- you get TRUE signal transference to the coils, and your tonality will show it.

* Spider assembly- I can't say there's anything too far out of the ordinary here.I used a high compliance treated textile.....And- she has a cupped profile should you need that much excursion..

*Voice coil... This is a light weight KAPTON former, with SOLID AMERICAN copper windings ( NONE of that CCAW CRAP) Plus, even an import solid copper coil is 95% pure at best.

*Dust Cap- I found an old Jensen " Egg Crate" type/shape deep profile dust cap with that flat spot, so I thought- why not right?

*Surround- This is also a hemp fiber material, as it's part of the molded hemp fiber cone assembly...It was treated with special Eastman Kodak chemicals to loosen the fibers in THAT AREA ONLY, and aids in low frequency response. This was lightly treated with ReZon-Ex in order to prevent any cone edge resonance issues, and omit any secondary or "Ghost-Notes" from being reflected back into the cone, and into the air....

*That brings us to the star of the show... This is the proprietary. HEMPOPOTAMUS extreme curve-linear profile.You will NOT find this cone shape any where else...The cone itself was molded at 11 grams..

This really lowers Moving mass, and aids in speed, detail and resolution. This is possible to make LIGHTER and STRONGER cones, because the hemp fibers are longer, and "Thatch" together much better than the industry standard pine pulp...STRONGER and LIGHTER are the way you want to go for the PERFECT cone... It should be infinitely light and infinitely stiff... Which- is physically IMpossible- but this is a HUGE step in that direction compared to anything else out there..


This unit really is greater than the sum of its parts.... I can't really add anything constructive to the descriptions I've already typed..

***. Fully tested under diagnostics and operates without any rubbing, smoking, buzzing, holes, rips, or tears- it's basically a brand new speaker- ONLY BETTER!

Plus, I'm confident enough that you guys will LOVE this one, that I am including my 15 day " NO GAMBLE" return option from delivery date (((less customer damage))) if for ANY reason you simply don't like it, or you dis-agree with ANYTHING I just typed...

So, if you want an AlNiCo 12" high performance hemp fiber speaker for under 100, then here ya' go!

ANY questions or concerns, just ask.

THANKS GUYS!!!
