@Light bud I don't know much about that sub but I'd guess before shipping both ways it would be $190.

If i want to put a 400oz motor on a ab xfl or ap txxbd4 both 12 inch does a bigger motor mean it is louder with more xmaxx

The motor weight doesn't mean anything in regards to strength or Xmax. I did a video on how parts aren't universal you should check out as well.

on reconing tgesub as you did, doesnt it changes the parameters of the sub eith that coil being not the original and the higher round spider? so this would not be the same as the original, although it may out perform it.

If it's not identical it will change the parameters. The coil will be the biggest change because of the electrical side of things, the cone and surround can change a little mechanical but if the mass is different (even more than just the coil) it will also have an effect.

I have a set of Lanzar LP15's that need the same treatment. Do you guys offer this as a service? One of them has a loose coil but would love to replace both with an updated fiber reinforced cone.

I can do this, but I have to warn you the cost of doing so wouldn't be practical. It would only be worth the value of having working old equipment.

Would of not be easier to just turn the terminal around then cross over the leads. If only parts where as cheap in the UK would make a killing on making hybrid budget subs and doing JL subs as plenty cooked ones around

You can't "turn the terminal". The positive and negative would be backwards.

Why cross the wires under the dustcap????? Turn the connection on the "outside" instead.

@EMF Audio Yes i know the left and right standard. But it was only a way to not having to cross the wires , and get the + and - connetions correct.

@El Stefaano The markings are only on 1 side, and they're by color. Industry standard is positive on left, negative on right so I do it the right way. You would never know the difference if I didn't do a video on it.

El Stefaano

@EMF Audio At 11,50 you say posetive on voicecoil is on right side and the connection/teminal/tensillead posetive is on the left side. So you have to cross them. I guess we can agree on that. :) If we dont cross the wires - and + will be wrong on the terminal/outside connection (dont know the english word for it) , but if you turn the terminal/outside connection 180 degrees the markings on the terminal/outside conectins will be correct. And you dont have to cross the wires. When the terminal is turned the + connection/tensillead will also be on the right side at the voicecoil.

I think I understand what you mean, it just doesn't work that way. The pos and neg are just posts I solder onto. If you don't swap the wires it doesn't change anything but the label.

Hace 5 meses

@EMF Audio I mean you remove the connection (the goldplated connection on the outside) and turn it 180 degree and mount it back again. Then you can connect the + and - to + and - on the outside connetion without crossing the wires under the dustcap. Hope you understand what i mean.

OK where do you get your parts from? my sub is the older version of the ma audio ma100xe it's a dual 4ohm 300watts rms with the 600w stamped on the back of the magnet I believe it's a 2.5inch voice coil but would need to measure it before I by parts however I have never rebuilt a sub but I'm very good with my hands I'm a commercial electrician by trade and I've rebuilt motors and Transmissions so I have steady hands and I can pay attention and I have all the tools I just need to get supplies in material but do not know where are the best selection of a quail or parts would be and that's what I was hoping you would recommend a site to order from

I'm curious to why if you are using a DVC coil then why not convert the sub into a DVC sub. I'm figuring that adding another set of terminals would be easy enough.

It wouldn't keep it original though. I could have more easily just used a new dustcap too.

The subs in my car are over 20 yo with no problems, been in .many different cars, same subs. Converting to a single voice coil, if the individual coils are 4 ohm, you wanted a 8 ohm speaker, not a 2 ohm. You could have specified what the coils are and reminded viewers for system matching.

@EMF Audio thanks. It wasn't in the vid and I just wanted clarification

The sticker on the motor says "4 ohm" so a dual 2 was used. Believe it or not, I know what ohms law is.

cool build, I still wonder why you crossed the leads on the coil to the leads on the spider instead of swapping the input posts on the basket..

Hace 5 meses
EMF Audio
EMF Audio

Yes, always. Look at EVERY speaker, pos and neg are always in the same spot. That still wouldn't change how the terminals are labelled, which would have been backwards. I'm a fan of doing things the right way, not the quick or easiest way.

@EMF Audio "always" nope .. it's a good guideline or a rule of thumb, but I'd never have considered crossing the leads under the dustcap with all things considered just to keep that as a guideline.. 😉

Hace 5 meses

Because then the terminals would be wrong. Positive is always on the left, negative is always on the right, and they're labelled as such.

The idea was to keep it original as possible. Swapping wires would make the terminals wrong.

@EMF Audio you didn't have to cross the leads from the voice coil you could have just switched the push terminals on the outside so you didn't have to worry about them touching so much, just a friendly tip

I could have, but then negative would be on the left and positive would be on the right and that's the opposite of industry standard, it would also be backwards of how it's labeled. I'd rather do it the right way than the easy way.
