3 highpassed, 3 fullrange. I'd highpass a mod10 at around 200hz with a single order highpass, an in line capacitor (don't remember which value) but I'd use a 16 ohm mod10 to keep up with 5 b810's. The mod would need to be in it's own driver. The webers aren't really brighter, just voiced alittle differently. Or just go with 6 B810's. I just like the added clarity of the guitar drivers. Each guitar driver has it's own character and will greatly change the sound of the cab so, keep that in mind. The 3 I listed are all pretty good though, just different.
