Good video man👌

Thanks brother. 👍

What a beauty motor !! Nice basket too alot of builders use those baskets

How’s it going Chuck. You’ve mentioned the volcano top plate. Does that allow for a greater winging height, more excursion?

[@Chuck_Sanders]

Hey Miles, thanks for the comment. So, as you increase the thickness of the top plate, it can increase the overall motor force factor, but at a point it can start to decrease the peak flux in the gap. Also by increasing the top plate thickness, it is a wider field for the coil to reside in, when in axial movement, and most times allows for greater wind height to an extent. To calculate xmax, you take the wind height of the coil minus the gap height /2, and that gives you the xmax. The depth of your motor can be a determining factor, due to the depth internally which can dictate the amount of wind width you can run safely in an overhung design. I'm going to make another video on this all, this evening. I've had a few questions about all this lol. I hope that helps..

@@Chuck_Sanders YES. It helps. There’s a great amount of info in your videos. I kinda know what makes a sub work, but not what’s happening when it’s being damaged, or how all the specs relate to one another. I watch the channel man👍

@@milesbachelor8747 thank you buddy. I'm not the best at explaining without using visual. I'm going to try and do that in this next video.

I got new xv3. Went hook up has tapping nosie

[@Chuck_Sanders]

It could be several things, honestly. If it is new, I would contact Sundown.

What I hate is how some manufacturers cheat on what they spec on their xmax. I mean you said a 60 mm wind tight 35 mm top plate. So that means 12.5 mm x Max technically. I've seen some manufacturers call that 30 mm xmax. It's just like the Chinese subs/amps from the 90s when they were saying 5000 watts max watts on an amp that can only put out 500 watts or a subject only handle 500 watts. I had a discussion the other day with this X-Max misnomer and I just thought I'd bring it up here. For example, if this sub had a 20 mm top plate it would now be considered 20 mm xmax. The sub didn't just get stronger the top. They just got thinner and it's a mathematical computation

[@Chuck_Sanders]

Yes, people focus way too much on one thing, versus the whole picture. Thicker top plates provide better control and a more even force and saturation on the voice coil, but yes it does reduce xmax and doesn't get the motorforce as condensed so to speak. Thicker top plates can allow for increased winding widths, as long as you have the internal depth overall, to accommodate that. A deeper magnet is typically used for more internal clearance, which can aid and help accommodate the longer coil in those with higher excursion, but it has a much more difficult time focusing the magnetic force... again, my opinion. People focus way too much on xmax alone, in my opinion again. To me personally, I think those huge xmax subs tend to sound "washed out" or more muddy, under heavy excursion.

@@Chuck_Sanders Different bass goals...100mm wind heigh, tall TP, and 6" deep gap for sub 20hz door flapping. 30-40mm wind height for better sound from 30hz and up I guess

[@Mr.NiceGuy-xd3mm]

So what is it? Winding width or winding height, and you kept flip/flopping between the two. Reason why I ask because you are the first video on this subject that calls it winding width.

[@Chuck_Sanders]

@@Mr.NiceGuy-xd3mm they are both, one in the same. Some call it the "winding width" and others call it the "wind height" as they are both the same thing.
