Why do speakers improve with more powerful amps?


So, if I have a solid state amp that more than adequately powers a speaker, why do people recommend a larger more powerful amplifier to improve things?

Why do more powerful amplifiers impact speaker sound quality in a favorable way? Is it because more power is reaching the speakers? Mid and Tweeter drivers I was told receive a reduced signal versus bass drivers which receive relatively more power via crossovers.  All for the purpose of balancing a signal going to the various drivers.

You listen to the first watt.  If it sucks, you don't need 299 more of them.”

this could have broad implications.  I’m going to file this in my “ life lessons “ folder.

thanks for the post.

Both higher wattage and lower wattage with respective lower and higher sensitivity speaker combinations each render unique sonic results. Just as both tube and solid state (or then combination thereof) extend that further.

Maybe a closer focus and discussion over quality power supplies and current delivery would be more relevant than this endless sensitivity argument.

"So why the hell do people buy inefficient speakers?"

Speaking only for myself, I buy speakers that:

A - fit the space I have for them; and

B - sound good to me

In my case (home office/desktop audio), the speakers that fit the space and sound best always turn out to be sealed/acoustic suspension 2-ways. As it happens, that type of speaker design really does tend to sound better with more powerful amps, mainly because so much power is required to move the woofers harder and harder w/increasing volume as the frequencies drop to neas the speaker’s resonant frequency (bass reflex designs operate more permissively near their limits).

But having said that, it’s probably not true that an amp twice as powerful as the one that can happily drive a given pair of sealed speakers, would necessarily sound better. More like the amp that can happily drive sealed speakers to fairly loud volumes has to be more powerful than one that would happily drive bass reflex speaker to fairly loud volumes.

I have a 2.5 watt Decware amp and a 300 watt Aavik amp class D....a 35 watt 845 SET amp and a Belles 70 watt integ amp.also a Peachtree GanFET 400 watt amp.....They ALL sound DIFFERENT But they  ALL sound Great !......To each his own....If one was BEST....No one else would sell any equipment......I love this Hobby!

I wonder if what I often read is correct. That high current / high powered amps improve significantly the sound rendition at low listening volume like 60db.
