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:
15" Subwoofer Cone CN1512 | eBay
2 5" Alpine Type R Voice Coil Dual 4 Ohm ALPINERD4 | eBay
7 5" x 2 5" Subwoofer Spider Damper with Leads XHDZ040 2 | eBay
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?
