So that's a Kove voice coil? Looks pretty good for a spare parts build, how do you think it'll sound? Also aren't you afraid something will get in the gap made by the washers?

[ChaunB3400]

interesting

not @ all
we do this all the time / a lot of companys do this / Pulse audio / AQ / etc etc etc with wider gapps that this

going to burppppp it @ 3000watts @ 54Hz in the spl boxx


time took to scavenge parts about a week

Does this quallify me for the DIY poster boy or what

This is pretty cool! Whether you are a fan of SPL or not, it's still very interesting.

[Brian10962001]

See I could never get away with that, somehow a handful of staples, 2 brad nails, and one of those rare steel pennies would end up in my voice coil gap

[tinctorus]

Have you played it yet,I am curious to see if it sounded how you expected it to.

[lordbaccus]

not yet had to let the exopy set over night / going to glue the dustcap on after work today
then ill burp it with videos...

[chithead]

Looking forward to it!

Great build! Nothing i like more that a good Frankensub.

Just one question, did you just build a random box because i dont see how you could have possibly modeled it and get something remotely predictable?

I would assume if you knew what sub the voicecoil and cone were from,you could get a rough idea

I had built the box for another 15" a few months back... going to use it to test...

Fair enough Wondering how it will perform, good luck!

I have a question, this can really be answered by anyone that does this stuff I guess.

Then you build a frankenwoofer how do you go about assuring that the center of the VC itself is centered in the magnetic gap? I'm not talking round-wise I'm taking up and down. Yall know that this is very important right?

A different magnet will cause it to have a wildly different reactivity.

[thehatedguy]

Why epoxy and not rubberized CA glue? Would be instant (within seconds) curing...and 99% of speakers are built with CA glue these days.

[Billk1002]

Wow, I want a frankensub.
Now I know what I'll be doing next winter.
That is just awesome!
