You can not go from an 8 ohm cab to a 4 ohm cab it will fry the OPtransformer. Tube amps must match ohms or you will run the risk of ruining it. Remember you can only mis match ohms with ss not tubes, and you can not go lower than the ohms of the amp.
Also, are 4 ohm speakers better than 8ohm?
A 4-ohm speaker requires more power from an amplifier than an 8-ohm speaker to produce the same loudness of sound. This is due to the relationship between voltage, current and resistance in electronic circuits; for a given voltage, a lower impedance means a greater current.
Furthermore, can I plug a 4 ohm amp into an 8 ohm speaker? It’s a simple setup, on speaker per channel. It’s actually very simple. The “2 or 4 ohm” rating you are seeing is the minimum load impedance that the amplifier can handle. A single 8 ohm speaker is of course higher than that, the amplifier will have no problem powering it.
Likewise, can you plug a guitar directly into a cabinet?
Nope. The head is the preamp and power amp. First you mold your tone, then it puts it out for the speakers. Without the head, they’re just speakers.
Can you run a combo amp through a cabinet?
Can I Use a Cab With a Combo Amp? Yes. Provided your combo amp has enough outputs, you can easily connect extra speakers to your combo. Speaker outputs on any amp should always be labelled with the correct impedance depending on number of speakers connected.
Can you use a guitar amp as a cabinet?
You can use a combo amp as a head unit, or as a cabinet in a stack setup by connecting it to the external speaker or head unit that you’re trying to use, respectively.
Do you need an amp head for a cabinet?
In a head and cabinet setup, the head is the actual guitar amplifier itself. The cabinet is only a box that houses the speaker or speakers. You can’t use an amp head without a cabinet – you need both components.
How do you make a speaker cabinet for a guitar amp?
How do you wire a 2×12 cabinet?
How do you wire speakers in series parallel?
How many ohms is a 4×12 cabinet?
How many watts is a 4×12 cab?
If we go by the last statement, the 4 X 12 cab would have to have 42.5 watt speakers.
