I've got one of those I think they are the perfect size being in between an 18 and a 15 and I love the bolt together way they do things it makes life so much more faster the only problem is their motors are the weak point the glue is crap so they shift easy but this is an easy fix just swapping the motor with a better 4" coil motor like one I did a while back was a 15" hcca with a American bass xmaxxx monster 15 motor so it had 150oz more size and almost 1" inch deeper for more xmech and rated for 1500w rms more and let's just say that thing put the cool kids in the back of the buss lol
Had a hcca 12 from 1999 and had it on 1ohm, 3.5" ported mdf without sub weight was 90lbs. Had it at a 2.75 excursion and put bout 2500watts with a 2100hcca on 1 Guage wire.
Thank you for the great video explaining this. I'm rebuilding my kicker vx 15 and your video explained how to get my voice coil height set. Thanks again. I look forward to watching your other videos
Hey man! Nice job explaining this! I just rebuilt all my own subs and bought extra parts but I’m one coil short. So now I’m waiting to find another coil for the last one to get them done. But thanks for sharing this info! Very helpful
You are very welcome! Not sure where you got your replacement parts but I normally order from Lord of bass, if they don’t have what I need PSI (fixmyspeaker) or Springfield speaker repair are other options and if cost isn’t a concern gs audio Italy makes really high quality coils but they are pricey.
I just purchased 2 pioneer premier 2007 models (subwoofers) on marketplace,the person told me one of them had a blown voice coil and was repaired by a local.We did the woofer test and came out fine. My worries are that the original voice coil was apparently a titanium one and not sure what he used also comparing them both at home,i peeped to look where the voice coil was sitting and was not at the same height as the other subwoofer🤔is it normal? Will it level out with time or was it installed incorrectly what do you think?
i would say the new voice coil is almost definitely aluminum. as far as height of VC goes, there could be two issues. 1 the height was not set correctly and so the Windings are not properly centred on the motor top-plate (this will be unlikely to correct over time) or 2 the wrong voice coil was used and does not have the correct winding height but is centred properly. either way the person who repaired it did it incorrectly🤷♂️. it should be built to match original as close as possible IMO
@@MrM_Full-Send thanks for clarifying! Man that sucks.. I've been looking to get these subs for a very long time.. I would love to get these repaired but it's a question of finding the right person to get the job done correctly 😞
I only do car speakers 🤣. yes it is the same method for all speakers however there are some variations for different motor styles. overhung and neodymium are a bit different. same principle but additional items to consider
@@Saeidcaraudio the enclosure is critical. if not ideal start there. typically Subs are designed to optimize performance within the ability of the parts being used. this means there are limited opportunities to increase their performance. Not always the case but more often than not.
Pretty cool stuff. I just found your channel a few days back and very educational. I have 2 questions about voice coils. I know they are dual voice coils but I see one where's the second? Is there a need to have Dual coils, I had took apart my REL 1508s to swap out the drivers when they blew out and they had single 4ohm. Wish I saw your videos before I would have kept them and just fixed them. I disnt know how before but now I do. Second have you tried Silver Voice coils for the higher heat Handling? Also higher conductance would it really improve the magnetic field? Borreson uses Silver in their highest speakers.
Hi Jim, Thanks for checking out Mr M. Dual voice coils can be manufactured in several ways. Typically they are superimposed such that the first set of windings is adhered directly to the voice coil former (Usually aluminum) and the second is wrapped around the outside of the first windings. Depending on the specific coil they can be 4 or 8 layers. In a 4 layer(layers of wire), layers 1 and 2 are one coil and layer 3 and 4 are the second coil. It is also possible to make a bifilar voice coil in which both coils have their windings in every layer... They are not very common and I do not think I have actually ever seen one... I will spare you the explanation on this one because it hurts my brain to think about... Dual voice coils provide more wiring options for different amps, speaker combinations etc... no, they are not really necessary. As for silver... I have contemplated this many times.. But.. I have never tried it and I imagine the cost implications would outweigh the functional benefits.. Cheers, and thanks for you questions!!
@@TomJordan-e5s You need to balance your X-Mech variables. I made a video about it. As X-max increases, x-mech decreases. I like to pair my voice coil and motor so that X-mech is 1.5 times X-max.
this approach works for most motor set ups. it’s a bit more complicated for neo motors because they have a “fake” top plate and overhung motors but generally speaking this is correct
you need to know what basket and cone you are using. and motor to figure out where the coil will be positioned and where the bottom of the cone is. then you can determine how long the former needs to be… basket has two critical heights. surround seat to spider seat and spider seat to mounting flange. add the two basket heights. then subtract cone height. this gives you the distance from the motor top plate to the underside of the cone (provided you are not using spacers). take that number and add x-max and motor top plate thickness. now you have the distance from the bottom of the voice coil to the bottom of the cone. add 3/4” to 1” so your former is long enough to pass through the cone and have enough length to glue the cone to. contact me on FB or Instagram or email and i can send a picture to clarify this explanation
@@Ljtaz1122measure your motor depth and top plate thickness to determine winding width or height. Also measure your top plate thickness, and from your top plate to spider landing, plus any spacers you will use if you use one. That helps determine overall former height. Make sure to purchase a cone with the proper depth so that the former reaches the cone neck, and will still give you a little former exposed up top as a glue joint. You can buy a coil with too much former length and cut it down. 👍
i love the hose clap!! use couplers they come with rubber 2.5, 3, 4 inch and the claps then just cut a section out to get the correct circumference and adjustability. and always remove before you glue the cone assembly in. Certain baskets would make it hard to get off after
Lobo has some 8 layer 100mm winding hight 4" coils made not from CCA oooo noooo it's OFC that things got to weigh like 2lb or something like that. And it's like 120 or 150$ for just 1 coil!
coil was originally bought for a custom sub built on an RE destroyer motor but the motor has a tight vc gap so 8layer wouldn’t fit. Orion HCCA uses a similar VC. the Audiobahn AWT15X i built had a 4” VC as-well. i will be putting that particular Coil into one of the GSA Industries 12” Assassin Prototypes
I have been looking for this info for ages. Thank you for your time. You have my subscription. Looking forward to diving into your other videos.
I appreciate your time and effort bubba! Perfect timing, with me being at this point in me rebuilding HCCA 15"s.

Can u do a multi layer coil video on the different wyned ohm and configurations and do test to show the resistance?
like for pairing subs or wiring configurations for individual subs?

And after it’s all glued do you lift it off and remove the hose and clamp and shim be fore gluing the spider edge.
yes. the hose clamp would cause serious functional issues if it was left on when you glue the cone assembly into the basket 😳
@@MrM_Full-Send Yeah but you leave the clamp on there until you’ve finished glueing the cone on then pull it off and shim and glue the spider though.
@@edwardmatthews5899 i leave the clamp on for the entire cone assembly process. then pull it off right before i glue it in to the basket
"Now what i do to simplify my life" said immediately after spending a minute doing long division.
😂
So I have question say u bought a motor and have to figure out how tall the winding height needs to be on the former how do u figure that out

Hlw bro..this winding for any subwoofer voice coil
this approach works for most motor set ups. it’s a bit more complicated for neo motors because they have a “fake” top plate and overhung motors but generally speaking this is correct
How do you pick overall or former height?

@MrM_Full-Send Thanks! This helps clarify things a lot for me. If I have any more troubles I will contact you. Again thank you very much!
did you get the magnet motor from Lord of Bass? and thank you for the video 😊
yes this is the 165oz 2” vc motor from lord of bass. you are very welcome!!
No how do i request a biuld form you as im struggleing to get an old spl speaker reapierd as not common in uk
I am in canada so shipping might be prohibitive

What’s up man, do you build custom woofers, I wanted to Frankenstein a Orion Hcca 10 with a sundown Z motor/coil and everything else from the Orion
I build lots of custom subs😊
@@MrM_Full-Send how do I get in contact with you? For a quote
How do u determine winding height
measure the wires on the voice coil. i normally use digital callipers but you could do it fairly easily with a tape measure.
The question I have is how do you determine which coil (former) to buy because they have different winding height formers
