[QUOTE="headless, post: 5300368, member: 566363"] So I finally got around to replacing my old Kicker CVR 10" in a custom ported box. It served me well ever since my JL 12w6 died, but since I got my Power Line CS, I've been quite unhappy with it. It was the weak spot in the system - didn't get loud enough, and there was an obvious hole in output between ~60 and 80hz. It got plenty loud...but it got loud way LOW and didn't provide a good clean range of frequencies. So, i got in touch with Don (6spdcoupe) and now I am the proud owner of a Vanadium 12". It's a dual 4 ohm nominal voice coil woofer - the coils read around 3ohms each. I've got it wired up to my punch 100 with both coils in parallel, bridged, to a 2 ohm total load - giving each channel on the punch a 1 ohm load as a result, since it's bridged. You may know that the Power Line CS uses the same motor/basket as the vanadium 7" subwoofer. Sure enough, the vanadium 12" is like my power line CS woofer's big brother [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Check it out...same type of interwoven tinsel leads [IMG]http://headless.shackspace.com/PowerLineCSAndVanadium.JPG[/IMG] Beautiful woofer [IMG]http://headless.shackspace.com/VanadiumTop.JPG[/IMG] Mmmm, basket.
