I used a 12v power supply so this dictated how many LEDS.
I chose the brightest I could find (8mm at 3800mcd - whatever that is!)
Doing the calcs I ended up with 2 LEDs in each speaker, in series with a small resistor. The LEDs are quite directional and cast shadows in the horn mouth which I didn't care for. So I made small diffusers for each bulb using packaging material.

Forgot to add that if the light is too bright then it could easily be cheesy. My light is barely visible in daylight and comes alive as dusk falls. In a darkened room it is a soft glow, rather than a light display.

  I was also thinking a pair of LEDs would be about right. I like the diffuser idea. Must try this soon. Then invite my audio buddies over and run an A/B comparison for sound quality :-)
