Speaker Wiring Question.
« on: January 26, 2006, 09:58:38 am »
I've gotten an old cabinet that I plan on using on a 300T when I get the cash, and I have speakers for it already, I just haven't wired it yet.

Is there any way I can take Four 8 Ohm Speakers and wire them in a fashion that would make them 4 Ohm?

Two Ohm wouldn't be an issue, but I've got a trace elliot I'd use as my backup amp that everything I've ever read about it says to NEVER drop it below 4 Ohm. Thanks

Yes.

You can add a resistor that will suck up half your power.

You can use only two of your drivers.

In other words, you could do it, but any way you do will make things worse than simply running it at 8 ohms.

4 drivers of equal impedance can normally be wired to 4X their impedance, the same as their impedance, or 1/4 their impedance.  There is another possibility but it would be useless - three drivers on one serial string with the fourth in parallel - a terrible mismatch in terms of power handling capability... assuming equal drivers.

If the 300T will take a 2 ohm load, then I would wire all four in parallel.  Besides, the limitation on your trace elliot is based on that amp's particular design - which may or may not apply to the design of the 300T.  I don't know enough about either to determine... but if your 300T will operate down to 2 ohms, don't let the trace elliot stuff hold you back.
