Can I use 12 Ohms instead of 8 Ohms speaker?

[Prohor]

Recommend load resistance is 8Ω, what would be happen if I use 3 speaker ( each have 4Ω) in series connection = 12 Ω?

1. Can it damage the IC ?
2. Can it damage the speaker?
3. Can it reduce speaker performance?

No.
No. *
Marginally.

* Provided the speakers are each rated at about half the rated output power or more.

Speakers in series sound boomy because their resonance is not damped by the extremely low output impedance of a modern solid state amplifier.

I think it may little boomy but I wanted to test it's output. Little experiment it will be. Currently I have 8 inch 4Ω speakers but no rating printed on it . So I am not able to adjust it properly and when 100 w amplifier connected to these in series (4+4) as 8Ω recommended by the amplifier datasheet. It plays proper sound upto 60% volume but losses sound quality above 60% and seems noisy. With this I am trying to learn about sound system from goole and electronicspoint forum.
Thanks for your reply.

A loudspeaker is supposed to be enclosed in an enclosure designed for its specifications for it to sound good.
If too much power is fed to a speaker then it can be physically damaged (its coil smashes into its magnet structure) and/or it burns out.
