I figure who better to blow it up than Senchez

Rule of thumb is use as much wood and as little fiberglass as possible.

And yes that is a mobile post of a mobile post showing how to post a picture on a mobile phone.

Like so...

You do t have to use any insert links. Just paste the "IMG" link from photobucket to the reply box.

Upload to photobucket in their desktop version. Then copy and paste to SSA like normal. Works fine on my iPhone

You seriously need to stop listening to who ever you are learning from. Most kayaks are thicker than 1/8 inch and even those use some sort of foam or wood in their laminant.

I do t know about that.

notice there is double stick tape under the duct tape. I do the same exact thing. It's there to compensate for material thickness when building trim panels

Klippel testing was performed to verify BL linearity. Testing came out good but I'm gonna try a 12 layer coil before I proceed with production. The current coil is 8 layer flat aluminum with 50mm winding width. This coil will work fine with the current soft parts limiting the driver to ~35mm xmax which will take ~2,500 watts rms to hit. However when I get my new soft parts made allowing ~50mm - 55mm one way xmax it will need ~3,500 watts to reach xmax and I'm not comfortable using the current coil with that much power. Below is the BL curve. It is prematurely cut off due to hitting suspension limits. It should remain nearly constant to 37.5mm. Still with the current soft parts there is a loss of less than 10 percent BL to ~25mm. Below is coil offset. Extremely linear to 25mm sown by the red line. Below is suspension offset. Again extremely good Power compression displacement. again limited by suspension Inductance. Not too high but will be a bit higher with larger coil so faraday rings will be added. Again extremely linear. So far I am happy. It just needs a little tweaking.

Ohh what's the price looking to be?Not sure. Somewhere between 500 and 1000

Nope no presale

~5 months

Some things are being addressed that won't be shown until production is ready for resale. The changes being made may shed a few pounds from it, maybe. I will say I am concentrating on making it as efficient as possible, keeping BL as high as possible through out the suspensions usable throw. Things I'm doing will... 1) increase sensitivity 2) increase cooling 3) reduce motor noise by addressing superposition (google it. Not going into detail) This will be the best possible high output driver I can make using a 3" coil and the current soft parts avaliable. It should need around 2,500 watts to reach 35mm one way. In recommended boxes.

They are out their damn mind. That product cost no where near that much money to make. I should know.

You've graduated to big boy status.

Either the sub or LOC is out of phase. You can tell by the way the sub is behaving. Although it would have been much easier to hear without music dubbed over the video. 1) turn radio up 2) turn bass knob up 3) unplug one side of the rca from the amp 4) look and listen to see if the sub moves more if not the sub needs to be removed from the box (if you only have one wire coming out the box) and make sure the wires are not backwards on the sub. DO NOT keep playing the sub before you check this out if it is out of phase you risk burning the coil up.

That would be 4.42 gross before sub/port/bracing/walls... Not a ton of room.But still a workable amount. How much airspace do the DSS ethos 12's need? I know Q has it posted in his thread on them. Should definitely check them out. 1.5 net per sub. Could be squeezed down to 1.25

If it didn't weigh 85 lbs.

Really only tested to ensure BLx was linear. The top plate ID's on this sample is about 3mm too big FS. 24 Qts. .49 Vas. 190 liters These will change with the increase of BL but so far it's a good starting point. The final driver may use a 12 layer coil as it will need ~3.5-4k to reach ~50mm one way Xmax on the new soft parts I'm having engineered. I have someone testing it. If they don't burn it up I'll keep the 8 layer coil. The final driver will have faraday rings between the gaps on the pole and an aluminum pole sleeve.

He and Brittany are good friends. (My ole lady is also deaf). He was talking about your truck a few months ago.

Best of luck finding a better job J. With your skills you should be solid. Thanks man. Sadly now skills aren't cutting it the way a degree does. So many businesses seem to hire these 22, 23 year olds with little to no experience who have a degree, versus the 29 year old with 10 years experience. I need to figure school back out. J Guess they figure they trained the 29, 10 years ago. Why can't they do the same thing to the 20 year old and save 10 or 20 grand a year in salery instead of paying the experienced 29 years old.

Do you have a buddy named David that's deaf?
