Anybody know the specs on the speakers in the Sankyo/Bisty Lumina frames? They appear to be square edge 3" drivers. I pulled one on my Jule and it was manufactured by Onkyo and a 5watt driver but I didn't see the usual markings for impedance.

I was thinking if it's a 4 or 6, another way to quiet these down would be to replace the speakers with 8 ohm drivers. One of mine is making some random crackling noises and is probably due for replacement.

I was hoping to just replace the pair with some higher quality drivers probably from Parts Express. I'm an audiophile, what can I say. Any suggestions or part #s?

TIA
