Default 8 Ohm Woofer and 8 Ohm Tweeter. 4 to 8 Ohm Amp

Hi guys
I am building a 100W amp for my guitar amp. It can drive 4 to 8 ohm speakers, I read

I am looking at a 10" Woofer and a Small tweeter both are over 60W each. Both are 8 ohms
This seems to be the data on the 2 x speakers

The questions are: Will I need additional Caps or Chokes on this setup?
Will I need a crossover? Is it something I can make myself.

I am pretty new here, please go easy

Thank you
Regards Dez

You need at least a capacitor connected serially to the tweeter. Is this intended for bass guitar? If not, woofer+tweeter is wrong concept, there are dedicated guitar loudspeakers:

1st: You may not like the sound of an additional tweeter in a guitar speaker cabinet, as it literally may blast your eardrums (basically the same as said before).
2nd: A 60 watts speaker connected to a 100 watt guitar amp most probably won't survive very long.
Best regards!

This Amp is to be used mainly for vocal on a Karaoke Machine


As for the 60W Speaker, Do I add the 2 x 60W together, IE 120W?

No. Power capability even may be less, due to the tweeter's design that most probably copes the HF energy spectrum of music reproduction, which certainly is less than the high frequency output of an instrument's amplifier. Think of possible feedback!
Best regards!
