Sundown E-10/12/15 Prototype Photos

I'm so exited for the E line and the SD line! Its so much more practical for the average kid, or like my moms ride =D

Weights :

10 - 16.4 lbs

12 - 16.9 lbs

15 - 17.8 lbs

Mounting Depths :

10 - 5.5"

12 - 6.25"

15 - 7.0"

Add 5/16" for production due to the spacer I'm adding.

Thermal test completed @ 60 Hz sine wave :

TIME // CLAMPED WATTS

At ~400 the heat wasn't building up any faster than it could be dealt with as demonstrated by the minimal drop in power over time once it hit operating temp. So I feel the 400 RMS rating is well deserved -- it could literally handle that "all day" so to speak.

Then we hit it with more power after the typical 5 minute test as we normally do... it took over 2 minutes at 500-700 after that to kill it.

Conclusion... thermal capacity is a non-issue on this design @ 400 RMS.

I have a big, long, boring video I may upload for the test as well.

Little inside view after we cut it up :

so is that the Kicker CVR basket?

i really like how it looks

*edit* its not but it reminded me of it

Kicker owns all of their own frame toolings -- kinda similar, though.

[Purplehaze]

VERY SIMILAR! Looks like a nice new line up coming! I bet they have a nice sound too!

[sundownz]

I am super pleased with the thermal results... you'll find many woofers actually will fail within the 5-minute window without even go over rating -- it's a very difficult test.

Would you say this is on par with the DD 1500 series ?

[Supercharged DCs]

Looks comparable to the DD 1000 series.

Doing the best I can to reverse calculate the BL on the 1500 series (had to guess on the DCR as it's not listed) it seems the most comparable to these; assuming the same DCR the BL is darn near dead on even with these -- the 1000 has a weaker motor and MUCH higher Qts.

I am not up on the coil spec of the 1500 series (winding length) but I don't imagine it would take much more if any more juice than these thermally as these have one of the highest I've seen out of a 2" coil yet; even from longer wind lengths.

Sound-wise the DD will vary tremendously as DD drivers usually do as a result of the non-linear performance of their spider pack (which also happens to be beneficial for SPL at higher frequencies) -- it creates a "punchy" sound which many people enjoy (also described as "warm").
