i may pick one up just to try.. I like the fact it has a 10" spider and a 8 layer copper coil!



ps, IF ANY ONE HAPPENS TO BLOW ONE UP, PM ME!

 

Are you trying to recone? Email Nick at SI, he already blew up a couple of them for fun.

 

When will they make another deal like this? I obviously missed the first one.

 

Naw i have different plans for them lol!!

 

Dang. I just realized I only got one shirt after seeing your pics Marc.

 

So does anyone know when the next time they'll have another pre-sale cost like this? I'm dying to get some now after I've heard the reviews

 

no more pre order but next batch is like 3 months out atleast. If you go on the DIYMA forums i know some guy has his 2 for sale, he should of just got them now and last i saw they were still for sale i think he wants 200 shipped for each one. Other than that your gunna have to wait it out

 

Good luck trying to re-cone a BM mkIII. The spider, motor, coil, and entire moving assembly were custom tooled. If you re-cone one, it will quickly end in fail. ...the motors are absolutely gorgeous when they're plucked out of the subwoofer though.

You guys are the first to know, but I am entertaining the idea of opening up a second pre-order at $220 plus shipping. Technically that price is the same as the initial first 30 days of actual non-pre-sale production, but seeing how popular these drivers have been, the second pre-order will solidify that you are actually receiving a subwoofer once the next batch comes in before they're sold out again.

 

That was the point of the BM mkIII: Zero distortion right until it bottoms out. That's one of the benefits of using such an extremely linear motor topology coupled to a suspension that defines linear (honestly there is no "curve", the Cms "curve" is a straight line, which means zero suspension induced distortion). We have metered a single BM mkIII in 0.6 ft^3 sealed doing a 136 dB score sealed up on the windshield in a Jeep. If anyone expects more than that from a SQ oriented <3.5" deep SQ woofer, then you might want to look elsewhere for another subwoofer. FWIW: Technically the BM mkIII only has a 3.4" depth, but we chose to publish a depth of 3.5" because it allowed for errors / breathing room and it was better overall.

If your emphasis is on traditional toplogies and higher SPL to the ear (aka: higher distortion), do not buy the BM mkIII subwoofer. However, if you want your bass to come from the front of your vehicle and your mids to sound like they have a HUGE bottom end, the new BM mkIII is right up your alley.

 

so where are the vids guys!!!

 

Electrodynamic please do it. Let me know when you will be doing it again, IF you're doing it again. I would defiantly get one, maybe two.

 

I have two baskets with no motors or soft parts if that's all you want.

 

Since you have such an awesome dog I just might warranty dog slobber. A buddy of mine down in FL has a bulldog named Tank, and he's such an awesome dog that I've decided to get one. ...not right now though, but soon.

 

Mine came in yesterday. I sat in the living room in awe of how sweet they look. hopefully ill have them in within the month im about to start a full dampening project first cause my truck sounds like a damn prop plane going down the road with those 35 inch tires on it. Gotta kill some road noise first. Gonna do all my wiring when i get to the floor which im going to do last.

 

Here are a few pics of the motor by itself.

These pictures are of the motor that was plucked out of the BM mkIII subwoofer that did the 136 dB score a few days ago. The motor isn't perfect cosmetically because it was actually in the subwoofer, which means you can see the areas where glue was used to help hold the motor and neo slugs in place prior to magnetizing.
