Hello everyone!
I’m planning to build a very loud loud-speaker, that is the only goal. I wanted your guy’s input since i know nothing about audio, except the electrical part of it.
The speaker doesn’t have to sound good or be pleasant to the ears, just make a lot of noise. So the natural amplifier of choice would be a class-D amp driving a powerful tweeter!
The design ive though of so far:
Directional and mono.
Speaker:
8-ohm tweeter.
200W
106dB
52€

Texas instruments TPA3251/55 configured as PBTL, I already have a tested and working implementation of this circuit, only problem is that there are no characteristics for 8-ohm speakers so I’m not sure how well it would work.
Infineon IRS2452AM, seems to do the job but never tried this IC.
Driving it with a BJT but the power dissipation would be immense so not too sure about it.
Driving it with a FET but not sure how to make the sound relatively good, I’m worried the sound would turn into screeching if I simplify the driver too much.
I’m still just in the planning phase so any input would be appreciated, especially from audiophiles!
I’m trying to keep the costs down hence the 8-ohm tweeter, it was the cheapest i could find.
Please let me know if there is a better approach to making a loud loud-speaker, the main goal is to produce a lot of sound while still being able to hear the underlying song i.e. no air-horns etc. but
high THD is okey.
