Started with this, hung a coil and a cap on the original set up and put the two to the test.

Big improvement.

Then I introduced the CSS VWR 126 to the mix to replace the Fostex WR125.

We've now gone from having fun to being serious. This seems to the next step. Again, not the end all but a big 'wow' is in order. I will work on the stuffing but this is something the Fostex was not able to do.

Lots of experimenting with the XO at this point, all 6dB, all by ear.

Wifey says turn it down...

... I love it.

Very cool Cal! What do you think the crossover freq is about? The CSS VWR was what you were planning on using in the first place. You have me thinking now.... I have my wife's old JVC receiver with active crossover and built in bi-amp. Maybe connect my 20 in to the sub woofer and 14 in to the full range amp outs?

The large size makes me think this is like an OB with edge output.

Awesome experiment. Tell us more about the listening impression.

The last photo still shows the FF125wk?

There's a 5mH coil on the CSS and between 50 and 100 fd cap(s) on the LG driver. Experimenting continues. So far so good.

Try wiring those up in series and see if it snaps into place. Same parts i've tried XOing 4 ohm woof(s) to 8 ohm mid-tweeter. 200ish XO. I need to reduce cap value for next try

Dave, I will try when I have time. Hanh says I've had enough fun for tonight so I am off to Dollarama and T&T for the rest of my evening.

That visual is great. Something to be admired. I am still watching these threads closely despite not having jumped in myself.

Kyle my friend,
A glue gun, an Olfa knife and some foam board go a long way to some serious speaker fun. Talk to Dave if you need some experimental drivers. Honestly these things are a riot to build and play around with.

I've got some 2" fr drivers from a Logitech boombox that might work in the smallest of the horns. The other one I was interested in was using my CHR70.3s. I don't think anyone has tried that driver yet, have they?
