Default Project: monitor-XL reference values

Hi,

I will presentate my 2010 project en big monitor that I named monitor-XL.

After failing to get subbase with a backloaded horn.Project presentation Horn Almighty I became to make a basreflex two way that is flat down to 30Hz that is what I need with popmusic.

The project was realized in two weeks and I spend three-quarter of a year to tweak measurements and listening test to come to a high quality result.

92dB 1W/mtr 25Hz-20kHz

Super linearity and THD figures.


THD bleu second harmonic red third harmonic. Measured at about 1W with my ucd-class-d power amplifier.
up to 1kHz about -40dB= 0,01% and above 1kHz about -60dB=0,0001%.

See THD and step response hole two way system.

Nice looking speaker, I like the single angled side for horizontal placement, looks pretty cool.

Any chance you could show us what the crossover looks like?
