My friend is using the Lii Silver 10 on a four foot high baffle.....two feet wide....with four foot by one foot wings going straight back on the sides. He has measured 40hz flat in his room.....-5 at 30hz. The Silver 10 has a 28hz resonance. He added an ESS AMT on top using a copper foil cap above 10K......simply incredible sound. 98db efficiency. He soldered his speaker wires directly to the voice coil wires.....(he removed the binding posts on the speaker). This gives way better sound than going through a binding post.
Now he is going to add 2 15 inch woofers to each side.....he will bi-amp using a solid state amp and electronic xover for the woofs......and leave the 10 inch running full range or roll it off by using a smaller value of coupling cap in his tube amp. If the smaller value cap is a better cap then you have even better sound. By limiting the full range to above 100hz you will lower its distortion and increase its dynamic range. But, he has been listening to the 10 by itself for months and months now and is still Gobsmacked! The Lii drivers need at least 200 hours of hard playing to really loosen up. He has another system on the other side of the house and he can blast all day a new driver.
