Because it is difficult to predict what people want we (Analysis Audio USA) decided to let the customer decide whether they buy inboard or outboard crossovers. Some people place their Analysis speakers in a living room and don't want extra boxes and wires. Others want every last ounce of performance and choose outboard crossovers. Others like to have the option of trying active bi-amping at a later time. Even though the Analysis chassis/cabinet is rigid and fairly well damped there is still some vibration. Being a flat panel speaker the cavity for crossover parts is quite small so extra isolation is almost impossible. There is a noticeable improvement using the outboard crossovers. I have demonstrated this many times to potential customers. Outboard crossover cost more. That is a consideration as well. We use Dueland, Mundorf and V-Caps in our REF outboard crossovers. Those components do not fit inside the speaker cavity. We let the customer decide: inboard crossovers, outboard crossovers using the same parts as the inboards and outboard REF crossovers. I understand why most manufacturers don't want to encourage their customer to redesign their speaker crossovers. Besides the obvious, technical support becomes challenging. It is much easier to offer one flavor
