What is the Frequency Response of Typical Built in Laptop Speakers?

I don't own a laptop or I'd test it myself.

Any frequency response curves out there?

Thanks!

Just a guess but I would wager 150-5000hz +/-12dB

They're pretty bad and not intended for full range fidelity at all.

anything below 3-400hz is pretty much worthless but they might yield useful information on the high end

I'm thinking down -3 around 600Hz in the bass and 6kHz in the treble.

sometimes it sounds like they go from 1kHz to 1.1kHz though LoL

Really depends on the laptop. My 17" MacBook Pro's speakers are about as full range as I've heard on a laptop, but I wouldn't say it's the norm. On the other end of the spectrum, the built in speaker on my Mac Pro desktop is about as narrow band as I've heard, with no top or bottom.

The 600 to 6000 -3db points I guessed at prob not true for my 17" MacBook pro also. Remembering that I said -3db, not band limits, I think it honestly sounds that way to me in many laptops, but maybe hf response is better for my mbp, maybe smooth to 12khz or so.

agghhh...why can't people make some measurements and post some graphs...?
(even if its a half ass one like mine...)
why just guess...?
nobody ever bothers to test/check anything anymore...
ignorance is bliss, so i've been told...

here's a graph of a 15" MBP...to be taken with a bucket of salt...
(*this was not a very "scientific" measurement...just for an idea...cause i'm lazy...)
(*this is a bit of a troll so don't take offense anyone...i'm bored and had too much coffee...)

That's what I get on my 15'' MBP, but that's one of the better sounding laptops.
Lot's of people listen to music on laptopspeakers nowadays, it's something to consider when mixing... Also cheap flat TV's, that have a great picture quality btw, sound almost as bad as laptop speakers. The big boxes of yesterday sounded much better.

Does anybody else find that iPad speakers sound much better than most laptop speakers? I mean, still not good. Just much better.

Roughly 300Hz to 10kHz with pronounced upper mids - that seems like the ticket.

Thank you for measuring that!

My hp HDX16T laptop has about a 2" "woofer" on the back of it... I'm sure it makes all the difference.

I also remember my cousin having a 5.1 speaker system in a laptop he bought several years ago brand new for like $4k. I never got a chance to hear it tho.

I think the larger issues for these systems besides bandwidth is the stereo spread and the level of distortion - which with some systems I imagine is very high. Performing a sine sweep and watching for not just resonances but also distortion would be worthwhile!

I have a 15" MBP and this looks pretty spot on!

I'll also add that my MBP speakers hate anything between 200-300Hz, terrible distortion in that range

Not necessarily. Check this out:



You can hear this kick on absolutely anything.

Three things contribute: the overhead is positioned to hear the kick; the kick is being played like it's meant to be heard; and -- secret sauce -- the kick's res head is off and there's an upside-down snare drum inside.

From the graph, it has a kind of NS-10M flavor. Of course all laptop speakers are single driver mid-range focused.
