Currently, I have an old pair of AIWA SX-F20 speakers connected to my PC which stand vertically, though I was just wondering, is it fine to lay them down horizontally? Will it ruin them at all?

I'm just curious about this because when they are horizontal it appears to give the impression that they take up a little less space than when they're upright.

Thanks in advance.

Hi Rokkaz,
welcome to HA

Laying your speakers down won't hurt them physically.
But the directivity might be optimized for upright position, so maybe frequency response might (!) degrade a bit.

Thank you for the warm welcome and reply Sunhillow

I'm glad to know that it won't physically damage them (that's what I was unsure about), and about the directivity, I've compared it in both positions but I don't notice any significant difference. So I think they should be fine horizontally.

So, thanks again Sunhillow, I appreciate you looking at both those sides to my question.

Somewhere... A long-long time ago... I read about people rotating their woofers periodically to prevent sagging. So, this might actually be good for your speakers! In that case, they weren't talking about rotating the cabinet, they were talking about removing the driver, rotating it, and re-installing it! I really don't remember the details, but it might have been something like a 90 degree rotation once a year or something.

P.S.
I'm pretty sure I heard about this before the Internet existed, but a quick Google turned-up this:

i'm sure some of my audio tech head friends have mentioned that identical drivers placed either vertically or horizontally have 2 different effects, one increases percieved volume, one increases percieved frequency response.

not sure how it would affect that situation though. depends on the make up / style of the drivers in the speaker, and how many of them are in each, and what frequencies are shared between the different drivers per speaker.
