Hello,

Rekindling an interest in music reproduction and speaker design.  Looking forward to updating my knowledge of what’s available, and the current state of thinking.  I am interested in an open baffle, multi-way.  Not sure how many ways, yet.

Other option is the Lii Audio W18 $420/pair in serial with an F15 to 16 ohms to a small amp, to 4 ohms connect in Parallel.

There is no crossover need per se but you can add a 4.7mH or 6.0mH
air core, just avoid cheap iron core.

Thank you very much!

I have been reading about the F15 - it is certainly on my research list.
