The wiring of speakers to ensure the most effective load and to insure that they are all in phase will help to produce the best possible sound.
So long so you learn a few things about installing and attaching your speakers to have an effective resistive load, this is not too complicated.
MESA/ Boogie amplifiers can efficiently handle 4 and 8 ohms. Never run in a tube amplifier under 4 ohms if you are absolutely sure that the entire system can handle it properly; this can cause serious damage to the Output Transformer.
A few of our bass amplifiers can effectively plug an 8-ohm amp into a 16-ohm speaker. If you have any questions about your amplifier ‘s impedance handling capability, please consult your owner’s manual.
You can always have higher resistance (for example, 16 ohms plugged into an 8-ohm speaker output) without damaging results, but there is a risk that too little resistance will cause problems.
If the cabling is adjacent, speaker resistance reduces. Two 8 wired Ohm speakers in tandem result in 4 Ohm loads.
The effect of a resistive charge is easy to measure because both speakers have the same resistance. It is not really recommended to wire specific parallel resistive load values.
Connect Speaker A’s positive side to Speaker B’s positive side – Connect Speaker A’s negative side to Speaker B’s negative side.
Series & Pair Combination
This is actually just two sets of paired wired speakers. That is how you keep several speakers at a constant load. The importance of this is more evident as you choose to add more than one cabinet to your amplifier. This is when you need to figure out the loads and how to wire them to the amplifier without applying too little resistance.
When you run an 8-ohm tube amp into 16-ohm speaker, you only fit the single speaker impedance to the amplifier, and you are done.
You would have a range of speakers in certain situations, and then you need to measure the “load” that the amplifier needs to support.
Consider the amplifier body as the head and the speaker as a separate cabinet by using a Combination Verstarker. Plug your Combo speaker(s) into the amplifier chassis, as you would any cabinet extension.
When you run a higher resistance (e.g. 8-ohm output in a 16-ohm cabinet), you may notice a slightly different feel and response.
A minor disparity may have a darker lighter sound with a marginally lower production and an assault. This reaction is the product of the amplifier running a little cooler.
