dcm4588 Posted December 28, 2012 Author Report Share Posted December 28, 2012 Someone beat on it pretty good and tore the tinsel lead from the spider on the voicecoil that's still working. Definately time for a rebuild.

CJ18 Posted December 28, 2012 Report Share Posted December 28, 2012 A 3" coil is a 3" coil no matter what. The best thing you can do if you want to put 3k to it is to build the box to suit the power. I can have the recone built with 1 extra spider to help with the power handling, but the biggest factors in the power handling will be 1) clean undistorted power and 2) proper box size. I would personally recommend 5.25-5.5 net for a true 3k clamped power. Quote Link to comment Share on other sites More sharing options...
dcm4588 Posted December 28, 2012 Author Report Share Posted December 28, 2012 That's pretty much what I figured. I was more or less curious if there were options for stiff spiders and things of that nature. I do set my gains with an o-scope so it will be clean power. Whether it's a full 3k or not, I would say since my amp is an AP3k, it will probably be a little less. I obviously won't be playing full tilt 24/7, but I do compete. My main concerns are for burping and demos. In all truth, this is actually my first 18" speaker and I've been doing this since 04'. So I'm in the process of learning the parameters of them to try and build a box that will optimize the output with what I have. I figured since I'm at the step of reconing I would explore all options of power handling, which would leave me with what airspace I can SAFELY run this speaker on, with the power I have. I understand and agree with you 100% on the 3" coil comment. A 3" coil will only handle so much power...clean or distorted. I suppose I should handle the problem @ hand first, which is needing a recone. Then I guess it's back to searching through these forums to see what others are having success with for a box. I just don't want anyone offering to design me one for money. I know a guy's gotta eat but I can do all that by my self if I know what airspace to use and what port tuning these like. But the recone is for sure step 1. I'll need a dual 1 ohm with a stiffer spider or something of that nature I suppose...

thorshammer Posted December 28, 2012 Report Share Posted December 28, 2012 Have it built with 4 or 5 spiders. I'm partial to 5 for larger power. Build box to 5.5cu before sub displacement and tune to 34hz. Quote Link to comment Share on other sites More sharing options...

dcm4588 Posted December 28, 2012 Author Report Share Posted December 28, 2012 Lmao. I suppose I should take the advice from the one who would know then. What would you sell a full rebuild for? D1 ohm, 5 layer, nothing else special?

dcm4588 Posted December 30, 2012 Author Report Share Posted December 30, 2012 and when you say before displacement, I'm sure you mean before speaker displacement, not port as well, right? I would assume 5.5 cubes net plus port, minus speaker displacement?

CJ18 Posted December 30, 2012 Report Share Posted December 30, 2012 5.5net is after all displacement. Quote Link to comment Share on other sites More sharing options...
thorshammer Posted December 31, 2012 Report Share Posted December 31, 2012 Close Cody. I was saying 5.5cu after port displacement then drop sub in Quote Link to comment Share on other sites More sharing options...
