Analyzing the prototype.

let me test a proto lol

I only order one. Otherwise I'd let you play with one..regretting only getting one.

No Azz shot. What is the intended goal of this sub. Spl, ground pounder, linear and high output?

A street beat woofer that sounds great at a good price. Unfortunately part of the design requires a large toplate to get the proper strength because of the coil windings/build. So it's not excatly cheap but really like this design Over the others I built..

The original design aspect was to get inductance as low as I could have a good amount of throw and the power handling to reach those levels of excursion. 100% of the coil in the gap it's about 25 millimeters x max.. at 70% it's around 34 millimeters x max but it's really designed to stay Within about 90% of the coil in the gap(ruffly 28-29mm) to keep the BL curve flat as possible. I chose not to use shorting rings because it's will substantially lower bl. I might end up doing a magnetic Id shorting ring but it actually sounds great as is..

In short to simple answer your question is it's built to be high Excursion, low distortion and high output driver. we missed the target moving Mass but I actually have plenty of BL for the mass and 1w/1m efficiency after broken and is about 88 DB which is actually pretty decent for such a high throw driver.

Whats the weight difference when you double the former thickness?

it won't be much. 10 15 grams I'd imagine.. the actual mms of this one is 355. I weighed the soft parts personally..

Just curious,
What are the dimensions of the motor? Gap ID, OD, gap depth, top plate height, bottom plate height, ferrite slug thickness and overall diameter?

Triple stack 255x25mm slugs topplate is 35mm x 250mm same for the backplate but bumped.

The gap not not exactly sure but the coil of is 3.2in.. it's actually tight. Not like alot of other drivers. The driver weights 88 pounds. It's freaking huge. It dwarfs even the big 4" coil drivers.



Next to a aq hdc3 15!

Doesn't look like it weighs almost 90 lbs.

That's a 40 pound hdc3s next to it.. lol

Very cool teardown; thanks for the pics! It's interesting to see how close to the limits equipment can be tested (or exceeded!) before failure. Reminds me of the 60 HZ AC 'test', only a little safer and you can get some info out of the experiment.

didn't notice your post till today. no way id go without testing the limits/failure and not try to improve it! a-lot of companies today get a prototype built. it is competitive and start production. i want to make **** sure its a great driver.

Looks like it does to me, roughly big motor as my dc lvl 5 but much longer basket

i guess ill have to put a pic of it on the scale. lol
