All about your K9 Series Subwoofers: Wiring for 1 DVC 4 Ohm SUBS: Wiring for 2 DVC 4 Ohm SUBS: New Page 1 Description: The Rockville K9 series has been our best-selling series of subs and it just got even better! Say hello to the K9 V3. This sub is a game changer. We improved the performance and cooling like crazy! Our engineers did some minor tweaks that give major results for Bass heads who like to abuse subs! Weather you are an everyday user or someone who pushes the limits of your equipment the K9 V3 is for you! We made the following upgrades that will keep the voice coil cooler improving the subs ability to take constant abuse. 1. The Dust cap was upgraded to the same one we use in our Punisher series. It is top of the line. We figured it just cost us a couple dollars extra, so why not throw on the best Dust cap. 2. We added an inner dust cap that stops heat from building up in the voice coil. We also made our pole vent smaller. The combination of these 2 changes keeps the voice coil significantly cooler when you are playing bass heavy songs or test tones. 3. We added a voice coil spacer that vastly improves the performance. 4. The cone has a smooth finish that allows the dust cap to be glued on more securely.
