Please find the FR, Z and schematics attached. FR is missing bass port contributions, so the real -3 dB point is probably between 55 and 65 Hz.

Introducing the LM-1, small glass smooth 2 way speaker
The LM-1 is a small, two-way speaker system using a 1" Vifa ring radiator and 5 1/4" Peerless woven fiberglass mid-woofer. The frequency response and distortion measurements are suitable for music production, desktop or home theater use. The final cost to build is estimated at $500/pair or a little less and fit into either the Dayton TW-0.25 or TWC-0.25.
While the sound quality is high it's still a small monitor with limited bass and volume.
Full free construction details are on my blog, feel free to discuss here. All parts available from Parts Express.
