Prototype "SA" Series

[Tyan 1]

I have 7 lines planned total.

that means u r going "big time" :bigclap: :bigclap:

hey Jacob

will we ever see some of your Subs .. here in Europe that would be sweet

and how many lines of Subs .. will there be ??

where in europe are you?

Hey Jacob, is the Audiomobile MASS clone gonna be one of the 7 lines? Haven't heard anything about this in about a year.

Probably not going to happen any time soon... unless I decide to do a limited production run at some point. It is possible but on the back burner.

those would be niceee

one of those would be nice in my dad`s car

any hints on what the other lines of subs might cater for marketwise?... ( any ultra low end monsters ie rexxx killers? )

[sundownz 197]

Nightshade with a copper coil is a pretty good low-end monster - I may consider offering them a bit later.

[sundownz 197]

So far so good in testing.

I used the old test box from the VW in the Jeep... which is ~2 cubes tuned around 30-35 Hz or so, port nearly touching the hatch (eg: very poor setup for getting numbers).

Peak still @ 50 Hz -- 138.3 dB with ~720 watts or so.

I played music with constant power from 500 - 720 watts clamped in this box for 5-10 minutes. Woofer did not display any mechanical stress except on 720-watt peaks -- will probably make the magnet stack taller for production to avoid that as the coil can contact the back plate at 26.25mm of excursion, which I was able to achieve.

I also played the 50 Hz tone for several minutes at the same power level as before - score stayed pretty constant.

I then turned the frequency up to 60 Hz and let it play... didn't really clamp the power at first but about 20 seconds in I got curious. Sub was seeing 1800+ watts clamped power and by the time I hit pause was doing so for about 40 seconds or so. Sub is still just fine.

So... probably 15 minutes or so of at least 500 watts and as much as 1800 watts on sine wave material and no issues at all.

Design seems to be meeting it's goals so far.

I want to make a top plate for my SPL box to see what it does in there as well just for kicks

PS: I made a mistake on my spec sheet for the factory... forgot to tell them to make the coils D4 so I got S8 coils... I have two 3000s strapped on it to get this power level

Oh yah... and most importantly the driver sounds pretty darn good to. This test box is tuned low so I was able to get a feel for the sound a typical customer will experience and I am pleased with it.

really good!

waiting anxiously all these new products

Dang a 2.5" coil taking 1800 watts for over 30 seconds!

This driver looks sick as well as it performs.

[sundownz 197]

We made a top plate for my SPL box @ lunch - so we'll try it in there too!

[sundownz 197]

178 volts / 9.5 amps clamped peak... 9.4 ohms per amp calculated... 1691 watts.

Can't get any more juice than that at 50 Hz in my SPL box. The woofer was NOT showing any signs of mechanical strain @ the 50 Hz burp frequency in this box -- the sub has more in it and, for that matter, should probably be in a smaller box as this is my 15" woofer SPL box So I am very pleased with it.

145.2 dB score in the SPL box.

I kept playing it for a while at the same level... probably a few minutes. Still no issues with the sub.

The top plate has a gap under it as I used some neoprene foam as a gasket since it is just temporary.

[sundownz 197]

Making a few changes and getting a new sample in a few more weeks:

1) Adding 10mm to magnet stack

2) Moving vent holes closer to the pole by 5mm

3) Making the coil 5mm taller

4) Creating a plastic spacer ring under the basket

This makes total x-mech 33.75mm vs 26.25mm now.

Bottoming it out is really the only way to hurt this design within reason. I accidentally put an amplifier in front of my port, effectively making it nearly sealed (a big sealed box at that)... and started the vehicle with the volume at the "testing" volume level. Bottomed it HARD until I realized what was going on and it did kill the coil - cut it down and it was a purely physical coil failure, the coil still looks nice and new otherwise.

With the increased x-mech this design should be nearly bullet-proof!

So what comes first, this or the Z15?

[sundownz 197]

So what comes first, this or the Z15?

Hard to say... there are alot of variables.

[sundownz 197]

Looking like Z15 first as I do need to re-prototype the SA-12 based on the above listed changes

[kkk4 3]

All these new models when they are on sale?

I saw that there are other products that are not listed on the scales, subwoofer and amplifier, I send prices?

[sundownz 197]

We do not have an exact time for when these will be available.

[kkk4 3]

non funziona

[audioxtremes 0]

Hurry up on these!

I want some.

[sundownz 197]

Factory finished my new prototype - I should have it soon... thing is a MONSTER:

It is as big as it looks

[Kanaworm$ 292]

Sweet! That thing looks impressive!

Can't wait to see the test results
