Can you ever have too powerful amp for speakers?

From my experience, is better to have an amp that has higher power rating than the speakers, as gain settings are essential for your equipment durability.

The degree to which the volume knob gets twisted depends on the gain of both the preamp and amp (s) and the sensitivity of the squeakers…. mostly. This may or may not relate proportionately to the amount of power on tap. It does relate to the amount of power being generated/used for a certain volume level for a certain distance.

The more sensitive the squeakers, the less the knob gets twisted up… be it a 100, 200 or 350wpc amp.

Factors that play into this scenario are the amount of gain the preamp provides, the input impedance of the amp as it relates to the output imp of the preamp, impedance curve of the speaker system, their sensitivity, the distance from them to the listening position and the desired SPL.

For ex… Merely lowering the input imp of the amp alone, will force the volume knob upwards if all else remains the same.

Lowering the sensitivity of the loudspakers will force the knob up too.

The size of the room also will come into play regarding the spot the volume level resides at more often than not.

So there are several variables at play as to where the control gets to routinely.

The only bad spot for the volume knob as I understand it is setting it past 1-2 o’clock. If at 2 o’clock you ain’t satisfied with the SPL/vol level, some changes are in order for that system.

I’ve also heard here via other threads, depending on the type volume pot itself, (passive preamps?) the knob needs to be well into it’s range to realize less resistance and greater fidelity. Still I’d think getting past the 2PM spot a dicey situation, and not recommend doing it..

More power though is not a bad thing. Tons of info via many threads here will indicate just that. Each systems power needs or output will have it’s own precautions and configurations as the result.

Personally, I’d not lower my available power output just to get my volume knob farther up into it’s overall range.

If my preamp volume gets to the noon position, it’s because I’ve gone stone deaf, or very nearly. It’s either that or the neighbors across the street want to hear it too…. or I feel they should.

Alot of times speakers get blown when the amp starts clipping because of not enough power.

Blindjim,

Good stuff.

I'd add that in addition to sensitivity, speaker design and directionality can matter. More directional speakers will produce higher SPLs at the sweet spot than less directional or omni design speakers. The reason should be apparent, its like the pressure generated by a garden hose nozzle delivering a focused stream of water versus one that is set to more of a spray pattern.

With omni speakers, there is more leeway to up the volume further without being blasted out of the room, all other factors aside. I percieve higher listening levels to be less fatiguing on my omnis as well in comparison to my more directional monitor speakers. With omnis, lots of power can really be put to good use with less danger of damaging your ears as well IMHO.

NOPE if it is a good one.
