    Subwoofer recone gurus, check out my plan please

    I am piecing together a recone for a Dayton HO 15'' since to send it in is the same price as a new sub. Here are the specs of the frame/motor I measured using a digital caliper:

    Pole OD = 2.53''
    Gap = .145''
    Top Plate ID = 2.82"
    Spider landing to top plate = 1.113"
    Distance from top of pole to back plate = 2.089"
    Surround landing to spider landing = 3.5"
    Frame OD = 15 1/4''
    Spider Landing= 7.5''

    I am looking at using the following parts from Ebay:

    cone:
    15" Subwoofer Cone CN1512 | eBay

    voice coil:
    2 5" Alpine Type R Voice Coil Dual 4 Ohm ALPINERD4 | eBay

    spider:
    7 5" x 2 5" Subwoofer Spider Damper with Leads XHDZ040 2 | eBay

    dust cap:
    7" 178mm Carbon Fiber Dust Cap Subwoofer Recone Speaker | eBay

    I have a Hobby Town close so I will get the rubberized CA glue from there. Does this look like a good plan? I was thinking I may have to get some spacers for the motor for correct voice coil placement. Any suggestions?

    Yeah, that's the only coil I found that seems like it will work with this sub. The only thing that worries me is that they Type R has much more Xmax than the HO 15, which leads me to believe I might have to space the motor out due to a longer coil. I guess I'll just have to see or hope someone knows LOL

    Do the math and see how much rearward clearance you will have with the coil centered to topplate.

    I'll sit down and do that this evening. I didn't even snap that I had all the specs to do that. Thanks for the insight.
