3 - way system w/Edgarhorn tractix

[clubman]

Looks like alot of fun...One question. I am new to crossover building. Are those start/run capacitors like used in hvac systems? I didnt know you can use those for audio?

In this case I had no oil caps in the rest of the crossover and needed a 24mfd cap and had some oil caps handy.

Most oil caps work for crossover duty if they test okay for value and ESR. I don't have a ESR meter, so I just test them individually on a cheap paper cone tweeter for sound quality.

Here's pics of my quick and dirty crossovers minus the zoebel(oil cap and resistor).

Now I definitely hear the bottom end dropping out below 60hz.

Time for a few subs to be added next week when the time permits.

Imaging is quite nice, still much tweaking to be done yet!

You have room issues;
move stuff out of the lower level finally, and try that environment. In your lving room, the subs will sound great in the garage...............

Still waiting to get new roof and repairs done. Ins company approved the claim, just need someone to interpet what they are paying to have fixed. The paperwork looks greek to me.

I hope in a week or two I can have the subs added to the system and rewire the crossover properly. I wanted a quick crossover to use to test originally and so just kept slopping components together with wirenuts. But I know I have to rebuild it neater and will be adding and deleting a few components and will use the terminal barrier strip more efficiently.

Nice job, I'm working on a similar 3-way project with a DIY rectangle 225Hz Edgar horn on 2482's with 18" 2245H for the bottom and an Eminence APT-200 Tweeter. I need to finish construction and i'm torn between active and passive crossovers right now. BTW I spied some Cornwall grills in the background of one of your pics. Do tell...........

Their main purpose in life is to kill sound reflections.....

I never had a pair of Cornwalls, just the grills, so this puts them to good use.

A fully horn-loaded 3-way system would really utilize the full potential and efficiency this system has to offer.

I'm contemplating cutting down a A7 VOTT cab for the midbass horn section and port it below like the 816 cab system.

It's running nicely now, but still have many tweaks to do on the crossover and better voice coil alignment with my next baffle boards for the MF/HF horns.

Hi Ron, I use to run A7s and always wanted to try this mod. Close off the back of the top portion of the A7 so the bottom is seperate. Then stick a 2245 in the bottom as a front firing sub. I've never heard a set up like that but I think it would sound great. Cheers.
