As the title above says, I need some help with info on my transporter series cabinets from Hartke. I have the 4x10 one and the 1x15 one. Here is the info i have on them and is all that i can find online: 4x10 = 300watts power handling at 8 ohms. 1x15 = 150 watts power handling at 8 ohms. Questions are: 1.) My 1x15 blew. The old man is an electrician and said that he gets no reading at the voice coil so that must be bad. I know these can be replaced but... Which voice coil should I get? What should I look for etc... 2.) Also, I just got a SWR WorkingPro 700 Bass amp. The 1/4 inch speaker inputs are wired in parallel. I know that means my 2 8ohm speakers will end up getting me 4ohms output. If it was series then i would have somethign like 16 ohms. Anyways, When I see parallel cabinets, they have 2 input jacks. My hartke's have only one. What does that mean to me if I connect my 4x10 only or my 1x15 only? Won't my amp be i guess you could say expecting 2 connections in the back? My 1x15 blew like i said before so I will be running my 4x10 through the SWR amp for a couple weeks. Wwill anythign bad happen. I am clueles to this this whole ohm and power thing so this is why I ask... Thank you all who can help me in advance.
