Matching Speaker Watts to Amp Watts

Post by Bob Jennings »

I need some advice on this subject; for example: if I have a 100 Watt Amp or Head, what Watt Speaker or Speakers should I be connecting. Is there any danger if their mismatched--like connecting a 50 Watt Speaker to a 100 Watt Amp or vice versa? I don't have enough knowledge in this area to even be dangerous other than connecting them wrong and finding out I blew something up.

Any advice will be deeply appreciated.

I think it all depends on how loud you play.
Usually there's not a problem at normal levels.
You run the chance of blowing a speaker if you get too wild and crazy!

Bob: No offense meant, but your question is WAY too general for an accurate/safe answer.

If you know what you want to do with what gear specifically, we can give you a more accurate answer.

Also, this would probably get more responses in the Electronics section.

ajm,

If I would take offence to your response or anyone else, I have no business being on this Forum. I only know enough about electricity to probe with only one hand and keep the other hand in a pocket. I once laid a hand on a Transformer while changing a motor in a turntable---this unit had sat idle for about two weeks. After getting a jolt, I thought I had the unit plugged in; but saw that I didn't. Anyhow, I probably wouldn't be telling this had I done it with a Super Reverb!

This is what I have: A Peavey XM 6 Mixer, 150 Watts at 4 Ohms--I want to connect two Gemini GT 1504 Speaker Cabinets with 15 inch speaker in each rated 175 Watts at 8 Ohms each. Is this a good match? It's for a PA System.

You should be fine.

Two x 8 ohm cabinets in parallel will give you 4 ohms (which is the minimum load recommended, by the way).
The jacks on the XM6 are in parallel.
That should give you about 75 watts going to each speaker (potentially).

If you haven't looked, the manual is on the Peavey web site for downloading.
