THE FOLLOWING ARE THE FINALIZED PARAMETERS FOR THE 12 INCH AND 15 INCH DSS ETHOS TRANSDUCERS (NOTE: physical dimension will be added soon) 12 INCH DSS ETHOS re 3 ohms Le 2.94 mH Qms 5.91 Qes .54 Qts .49 Fs 28.24 hz Mms 326.15 grams Cms .1 mm/N BL 21.43 T/M Vas 33.1 liters spl 84.99 1w/1m sd 490.87 cm^2 xmax 32.5mm per 70% Bl rating recommended power 1,800 watts 15 INCH DSS ETHOS re 3 ohms Le 2.94 mH Qms 10.6 Qes .69 Qts .64 Fs 25.78 hz Mms 362.9 grams Cms .1 mm/N BL 21.43 T/M Vas 95.93 liters spl 88.22 1w/1m sd 804.25 cm^2 xmax 32.5mm per 70% Bl rating recommended power 1,800 watts The design goals of these drivers were to create around 3 db of ripple and a f3 of 28 hertz in a recommended ported enclosure of 3 cubic feet for the 15 and 1.5 cubic feet for the 12 tuned to 32 hertz. Below is a screen print of the 12 and 15 in their respective enclosures.

Update on that burp box?

I read it as voice coil just fine

Reread and actual comprehend Op is talking about the voice coil itself and not the cone/basket. lol thx,its still early in the morning lol

No "tuning" with a T-line. What are you going to stuff with?

Decided to buy 1 more d1600 and have 21 total. 3 rows of 7 batteries.

You telling me my backs been hurting for two days now. On a side note. I'm gonna start slicing on a burp box tonight

did you read why these subs failed?

I'm sure he has to get the parts himself.. then have Nick build it. He also has other engineers who help design his equipment. That's 3 sources right there. Then sell it, 4 sources.. then us buy it, 5 sources, lol. Then go to a show and watch all the crazy videos.. 6,7,8,9,10,11+ sources AHHHHHHHH!

im sure the 18 is not far off.... im not sure about this.. only a personal opinion .. i think the 10 maybe offered in a different line because of its excursion .. i know that with some long throw high motor force subs like the etho it binds up.. an issue with the spiders i think it is... geometry just does not work out... i think... this is just me talking out of my ass.

while changing my configuration from 1 ohm to .25 ohms, i foolishly failed to wire 1 coil on each sub..... so i sent around 7K to 2 coils... 1 on each sub.. so 3.5K to each coil.... or there abouts..... and it took it in burps... but when i played music with that much power the leads failed after a bit .... 100% my fault

once i get 20 votes ill reveal what cone is new and what cone is old

well i did 5 burps... then i did 2 30 second street beat runs.. and i got smoke... then an hour later i went and did a hair trick on music with dani so i would say 2 or 3 mins .... you can see the heat marks on the leads... im sure they just got too hot .. thats alot of dirty power for 1 lead

one more vote...

Test i shall!
