Working with the Clio on crossover. This is a MMTMM with 4" woofers. The challenge was to get enough bass.	Finally, they got most of what they wanted creating a 2.5 way. We still aren't through as the impedence is a bit low for comfort, getting down to 3.5 ohms	This one worked pretty well with a first order on the tweeter- but looking at acoustics it is a very steep curve, over 18 db/ octave. They should be alright. This is 6" Dayton classic and an AV123 tweeter.	This one is a prototype 6 1/2" woofer that just isn't giving us the bass that it should. You can see that the kids fixed one of the problems with phase and have a very flat curve, but this one needs more work.
The students brought their speakers up for our first crossover worknight. We spent about 5 hours on three projects- and more tomorrow!	These girls really understood their crossover and what each part did- and it shows in their speaker.	This about as flat as it gets!	This is an MTM using the MCM 4" mod. 55-1870 and an AV123 tweeter. Using only a cap on the tweeter and an inductor on the woofer, it provides an 18 dB drop at 2500 using the natural drop of the tweeter. Pretty flat response - 2 bB. Another good project!
