First Saber build in awhile but it's a DOOM CRUCIBLE Guitar

I haven't built a Saber in years (since Disney killed my enthusiasm for them) and I've decided to build myself a Crucible guitar from Doom Eternal. It's still a lightsaber at heart just in a non Saber body. Currently it's going to have a strip of about 40 less on each side with flicker effects and all that. Just ki da looking into speakers. Since it's not a Saber body I'm not restricted to Saber size ones. In fact I can put a 4 -5 inch speaker in this thing. Just (from the CF manuals writings) I need 4-8 ohm speaker and no more than 3W.

If anyone has tried larger speakers or odd ball builds before, I'd love to hear about it. And I'll gave pics soon as I'm finishing up some of the 3d model to be printed.
