LaVoce CSF051.21 coaxial

I use alot of Lavoce drivers, mainly for pro audio. Their LF drivers are very good and mostly on par quality wise with B&C and others. I believe most of what they sell is made in China, but designed in Italy.

The pictured coax isn't that great IMO, mainly due to the cheap tweeter they use. I'd probably stick with a Seas coax which cost more, but they're worth the extra money if you need something decent. Unfortunately I'm not aware of any decent cheap coax drivers. PE has a 5 inch coax for 35 bucks that is hit and miss, with obvious consistency issues.
 
I made recommended 4 liter enclosure and tried how this sound. At least tweeter level is too high. I turned treble of my Yamaha amp down 4dB and it sound better. Couple of adhoc sweeps confirmed hot tweeter. Have to open back cover and look what kind of crossover there is.
