Hi all, I’m doing a project with a soundboard, where I will hit a button and a horn sound will be produced through a loudspeaker. I am going to be using an 11ohm siren speaker. I’ve tried using Amazon amplifier boards and the amp that came with the siren, but most siren boards cannot play other sounds without heavy distortion. I can’t find any mono amps on amazon that are either full range or actually the advertised output. Looking for at least 200watts rms. Thanks for your suggestions!
I'm not sure if this amplifier speaker is useful for you, but you can try:
