Thanks Wayne! With your crossover the 2226H & DE250 blend nicely...very smooth.

I have a question regarding the 2226H. With several of my amps I get a mechanical hum. I believe 60 hz as the hum doesn't increase with added volume. At first I thought maybe I had some bad solder joints but the hum is still there when connected without the crossover. The amps are old vintage SET so I'm sure the SNR is nothing great. I also have a pair of Ncore mono blocks which are silent with my other speakers but still have a very low level hum with the 2226H. Might the crossover placement cause any hum? I purchased the JBL's used & I hope there is nothing wrong with them. They do sound very good. Any insight is appreciated.

Currently I don't have any measuring equipment. I have access to some good mics so I will hopefully get some measurements soon. Once done I will post the results.

Here is a pic of what lurks behind the wall of where the speakers are set up. Perhaps once cleaned up some of the hum will be reduced. Thanks again!
