new question: Speakers

[Pontius2000]

ok. I just decided to open up my Roadster for the first time. it has 2 Vintage 30s as expected. what was not expected is that the speakers are 16 ohm. I thought the stock speakers were supposed to be 8 ohms? so, are these supposed to be plugged in the 16 ohm jack or the 8 ohm jack?

also, I think it's bs that they actually soldered the speakers in rather than normal wiring. I was planning on replacing one later on with a G12T-75. now I'm gonna have to learn to solder before doing so.

You need to read your owners manual. Two 16 ohm speakers equals 8 ohm load. Plug them into the 8 ohm jacks.

Trolling or whining? Two 16 ohm speakers in parallel wiring makes one 8 ohm load. A speaker connection that is soldered will be more likely to maintain it's electrical connection and thus be more durable (fun science fact: two dissimilar metals in contact with each other like you have with an aluminum blade push on connector connected to a steel speaker connector will cause an electrical charge. This exposed to air, which in itself is a corrosive gas, can cause oxidation that can degrade the connection. When soldered, the solder seals the connection from the air,thus reducing the likelihood of oxidation).

Long-winded, ain't I?

It's not so bad, buy a 16 ohm G12T-75 and wire things the way they were when you looked at the speakers. Series wiring adds resistance and parallel wiring lowers it. So ya, two 16 ohm speakers in parallel will be 8 ohms but two 16 ohms speakers in parallel will be 32 ohms. If you put two 8 ohm speakers in a 2 x 12 you'd have the option for 4 ohms or 16. So you see the problem here, hmm? http://professional.celestion.com/guitar/features/drdecibel/index.asp

A 4 x 12, however, is wired in series parallel so basically you have two series loops wired in parallel. Make sense?

About soldering, it isn't difficult at all and it makes for a great electrical connection when done right. Just get some solder and a soldering iron and don't burn yourself in the process. I am a huge fan of mixing speakers and I'm sure you'll be very happy with the results. Just make sure you hook everything up right so your speakers are in phase and you don't end up cooking something on your amp. Best of luck!

P.S. If you want an ohmage nightmare, my amp is a Dual running with one Rectifier tube and two power tubes so I have three slots empty. This changes how the amp operates so I have to have double the resistance of what each connection indicates. So I have to connect an 8 ohm cab to a 4 ohm output. I have two sixteen ohm speakers in my 2 x 12 but I have it set up so I can either run series or parallel so I can hook up 32 ohms of resistance to my 16 ohm output. Figure that one out!
