When I worked at ORION , 99% of woofers that were returned for "Warranty" were actually user error or Abuse. Very few were defect, I.E. inconsistent glue coverage or other employee oversight on assembly causing some sort of separation failure. But nearly all coil failure was caused by clipping amplifiers, and coil failure was the 99% that were returned.

Now you talked about a vented pole... any good reasons not to drill it out with a drill press while you have it apart? Of course you would tape up the gap to keep the metal shavings out of the motor and then install a faucet screen at the top of the pole to prevent debris from getting in?

@fabeybaby8213 2 жыл бұрын

The vents are around the spider on a piece of plastic that connects The spider to the frame and also on the plastic that is around the bottom half of the cone that connects to the voice coil so it kind of forces the air back and forth through the inside Gap of the voice coil and down under the voice coil and out the sides where the spider and Vents are located... I just don't know how efficient that method of cooling is. It seems like the velocity of the air flowing in such a tight spot would cool it decently but who knows I've seen a lot of burnt looking L7 coils...

@eatsleepbassrepeat 2 жыл бұрын

Kicker deleted the vent for two reasons 1) to reduce original machining charge 2) to sell you another sub when you thermal the coil ;)

@RJayRabbit Жыл бұрын

If your using a coil that is .2mm longer on the winding can you set the coil up offset where it sets higher to make sure you don't bottom out? Thanks Pat.

@RobotUnderground Жыл бұрын

It still depends on how tall the motor structure is and where the center is. Typically 2 mm is not going to make a difference but you still don't want to bias it if you don't have to

Hey robot I have a question/idea. You obviously know alot more than me about the mechanics of a woofer . But I also enjoy the hobby of rc cars.. got me thinking. The new brushless tech. Reversed the old way of motors. Putting the windings on the outside and mag in center.. I dunno exactly how it could work.. or if it be effective.. but seems like something new could be done to improve sub motors in this manner

If you have a drop in you don't need to measure. I should say if you have the proper recon kit you shouldn't have to measure.

I've ca glued the coil to the spider (shimmed) and upon sliding the cone over the former I'm seeing that it doesn't go all the way down to the spider,like on a store bought sub (Sundown dc ect.)

Does the top plate/washer affect the way the magnetic Flux is concentrated? If yes, could that lip be a win/win for higher Bl and also making it easier for the factory worker to center the basket? Or is it pointless? The dust ring around the lip makes me think it has no effect on centering the basket and it has another purpose

@RobotUnderground 2 жыл бұрын

It just gives a larger sweet spot, not always more BL. Many designs like JL have great BL with a thin top plate. Yes it might be easier for the factory.. But that's why I've been appreciating the American Bass motors that are bolted. No shifts either. no performance difference between overhung and underhung either. overhung just allows for more abuse.
