I agree with Walt (not the first time, he knows what he speaks, I have heard his stuff)
Two pictures
Maggy llla rebuilt xcover. I went for low DCR and I believe I gained a lot of efficiency. Large ga coils, caps in parallel to lower DCR and the Maggys sing with as low as 100 watts.

The second pic is the Carver ALS stock filter, and as you can see tiny ga wire in coils, 10 cent film caps and electrolytic caps.
This is typical of stock xovers. My 200 watt SS amps(400 into 2ohms which is where the Carver are) would not do much.
I replaced th passive xover with Litz-Riley and the Carvers are exciting, not very Amazing but exciting. I do not run out of steam at 110db at 20hz, but my house cannot take much more
