OK. I have a 8 ohm 15" cab. I also have two 10" (8 ohm) beyma speaker elements, a passive 2-way crossover (4000 Hz) and a 8 ohm tweeter lying around. Here is the quest. Can I use the two 8 ohm 10" and the tweeter to build a 2x10" cab wit a tweeter or am I in deep **** impedace wise? By my maths I would end up with one 15" 8 ohm cab and a second cab with a 16 ohm pair of 10" with a 8 ohm tweeter. What will actually happen here?
