Midrange - cones vs Compression drivers?
 
I know that this has gotton a lot publicity through the years, but people, on occation - do change their believes.

So which do you prefer...? - I'm planning a sommer build and cant quite decide...

Candidates are Community M200, Faital M5N12-80, P Audio WN 520N.

The two cones go a little lower though.. I'm mating the midrange with a frontloaded 15"

The Jbl 2220h

What do you consider midrange?? Where do you want to crossover?? I have a couple of horn/waveguide systems. I really like the JBL 10's like the 2122 or 2123. They run from about 250-300 up too about 1.5K in the two systems I use them in. They sound great the only issue can be the 1.5K crossover point in you want to stay away from there with a crossover.

My other system uses a 3" compression driver crossed over at about 750hz and then at 8K to a UHF driver. Another really nice sounding system but with the woofer covering the lower midrange.

You have to name your poison as far as where you want the crossover points to be. As long as the crossovers are well implimented either way will work.

20+ years ago I ran Edgar's 100Hz horn/2220Hz with a 250Hz tractrix/LE5 - 2220H was good for around 500Hz - the harmonic plot was for the K43 clone - 2220 was about 10dB worse in distortion

Hi Robh3606,

May I ask what horn you have used for the JBL 2123?

Thanks!

Best regards
Peter

In the system I use them in they are direct radiators. I have never horn loaded them

The crossover depends on wheter I'm using the cones or compression drivers. If cones I will cross them <300 - compression drivers >400.

I thougt about building a direct rediator high eff. system I've just convinced myself that horns introduce the lowest distortion and greates dynamic range - only REAL setbacks are coloration.

Crossover will be taken care of by my Deqx processor..
