Playing with Big Boy Monster 15"

[sundownz 197]

I'll throw up a few pics tomorrow.

We still have it in the ghetto test box, but it actually sounds quite good... two 1500s strapped @ 2 ohms are powering it, I have my primary battery, factory alternator, and two Powermaster D3100s backing them up.

Metered 144.1 dB @ 52 Hz in the test box - which is really terrible on the meter - same box in the YouTube videos of the monster.

I'd like to get it into a smaller box and strap the 1500s down really low and see what she'll do - then strap some 3000s on it

What surprised me the most is how good it sounds - obviously its not an SQ woofer but, it sounds quite good. Certainly does not sound like an extreme fart-cannon sub by any means! Now, that will all change when we test the 12-layer coil... but the 8-layer is *definitely* daily friendly even with the extreme 5-spider pack in place.

With me behind the controls the sub is not sweating at all with the two 1500s on it. I'll have to break out the ear plugs and really give it a run.

My ears are ringing a bit from driving home with it up really loud

Yep - in the Jeep w/ the test box from the videos.

Really need a sub up / port back style box.

lookin forward to see this boy in a "spl" application

will they be avaible in 12", or only 15 and 18?

[sundownz 197]

I would prefer to build them in 15s and 18s - but I suppose I could build them as 12s upon request.

Yeah.

HEHE.

Still not a "bad" number.

Snoopdan used sub back port back to do his big numbers. IIRC

Shipping is going to be ridiculous to Hawaii on these!

I think I could get darn near 150 out of it with a halfway decent box and two 1500s.

I'll have cliff (my sundown rep) piggyback them back to Hawaii for me :lol:

[TeamNemesis-DJ 5]

[jonbearsmt 919]

i went on youtube and searched sundown beast.

[lee 2]

[djjdnap 78]

8 layer wound? wow

[sundownz 197]

Its on youtube already?

Yah - I posted a bunch of videos in the original thread of us playing with the sub in the shop and one in Brandon's Bronco.

[stealth 113]

how wide is that new motor, 10.5'' ish... looks beast.

[sundownz 197]

It is a 10" motor - I am getting most of the added BL from the coil.

[sundownz 197]

I need to get Brandon to drive around in my car to test thing thing - my ears hurt before it is even thinking about sweating the two 1500s *laughs*

[stealth 113]

It is a 10" motor - I am getting most of the added BL from the coil.

thats a pretty high bl, should be able to take some mad power. good to know with those specs it still sounds great for daily

It has, literally, double the BL^2 / RE of the Nightshade D1

Now, with the 12-layer flat coil it should be more than that.
