Active external crossover

I’ve tried a few, I have yet to find one that is GREAT, just so you know. I have two F5 First Watt, (not made anymore), Probably the best of all the ones I tried. I found the combination of active and passive works the best. Neither on it’s own is GREAT. Together they are. The F5 is a 2 way for OB it has a step, that can be tailored, I modded the TWO to have a 3 way, it was a pain. Looked like something in the RUSSIAN space station, STUFF everywhere..:-)

ABOVE 3-500hz a great passive XO, you can work out the slopes, XO points, with an active, then take those specs and build an passive for the mids and highs. Easy as could be.. You can build a point to point, or buy a 2 way board. you could layout your own on a BB or wood block for that matter..

I use a Behringer 2496, 3 input (summation), great to a point. Makes it easy to work out the remainder of the XO 300.00 usd.

The better the active the less it will do, parts for multi XO cost money, the fewer the options, the lower the cost. WIMA will be in them anyway, if your lucky.

I suppose a Krell would have a pretty nifty setup, tailored to SOME speakers. They have never cheaped out, that I’ve ever seen. I have a few Krell products. $$$$ for sure..

If I took a picture of the inside of a First Watt B5, you'd chuckel, RED WIMA from top to bottom left to right... They are chock-a-block FULL

Mr Pass will help you modify his B5, just ask him, Very nice fella.

2-3 years ago, someone at First Watt, helped me. I need to do a value change. Fixed me right up

He will mix it up with anyone, great guy..

There is a place for correction, I could never get it to work without spending the same or A LOT more. The full blown DSP 20hz-20K just don't do it for me.. In a CAR, RV that type of thing, perfect.

In a HiFi environment, I found the take aways to great. 500hz EVEN 1K and down is ok with DSP. Add a servo system on the bottom 20-100hz it even get better... 500-1K and greater Passive or a full range driver with NO crossover.

The magic just goes away for me.. Everytime it sounds clinical in all the wrong places.. The first watt and a couple customs have been the best for me.. 2-3000.00 pair of B5 if you can find them Then you have to mod them.. They are for OB. He make another Active also.. Full of WIMA. 2%

B4 is still made, two way..I think..
