I picked up some speakers recently, an MTM layout which sound quite good, but I’m curious about the crossover design.
The tweeter is a Vifa D20TD-05-06 and there are 2x Vifa C13WG-08-08 wired in parallel for the mid woofer.
The application notes on the tweeter suggest 2nd order with cutoff at 5kHz, but the actual for these ones is first order LC at ~8kHz (0.47 Ohm 5W and 4.7uF Poly in series to the -ve terminal)
I’m wondering if maybe there should be an inductor on the mid/woofer, but the drop off is quite steep after 10kHz so maybe not?

You say the speakers sound quite good so I suggest you stick to the current formula.
The mid woofers have a natural HF roll-off which does not necessitate the use of a series inductor.
The tweeter crossover gives a shallow LF roll-off which may complement the HF roll-off of the mid woofers.
Simply avoid playing the system at excessive volumes in order not to overload the tweeter.
