Using a lower power amplifier cannot damage the speakers or amplifier, the speakers will just not be as loud. I had a look at the speakers' manual and it's far from clear what the 200W rating actually means, they say it is not a power rating and go off into a gobbledegook analogy about car engines and state troopers. Normally speakers and amplifiers, when ...

Amplifier sellers lie about output power. With a 24V supply, a TPA3116 chip produces 60W per channel into 4 ohm speakers with low distortion. AliExpress says 120W x 2 (240W) but they say the 24V current is only 3A (72W). So the 240W is a lie. Since the class-D amplifier heats a little then extra current is needed, use 24V at 6A. But music and speech are not ...

If have you a laptop charger 19.5V 65W to 120W, that should be adequate as long as the supply noise isn't an issue. You may have to put an RF cap to PE ground . If you have efficient 12" speakers in a large cabinet that are 92dB @ 1m @ 1W without crossovers, that will be more than enough . If you have a sub-woofer channel that's a bonus. Otherwise, it'...

Since you have the amplifier it should be easy to find some speakers to test it with and make some current measurements. You haven't specified what the amplifier's type is and power consumption will vary by Class A, B and D (the most popular). Once you have the current consumption multiply that by the desired run time to get the required Ah capacity (and ...

Tony Stewart has given you brilliant advice regarding how to use adhesive to mount the speaker. You can incorporate a grille in your 3D print design to allow the sound to project while protecting the speaker cone. If you're worried about even smaller objects penetrating, you'll need a second, offset grille behind the first, but that's trickier to print. ...

Bigger is better with a solid baffle. Otherwise the high self-resonant cone frequency will sound very 'monotone' at 600 Hz. Attachment is easy using any Polyurethane adhesives (sub-floor type in a tube) such as LePages PLxxxx or whatever. Allow 1 day to cure 50% and 3 days to fully cure with Rock hard 60 or depending on model. (Its also good for getting rid ...
