A stupid Question about crossover wring.

Posted by chopper87@aol.com (A) on August 12, 2011 at 19:50:29

Ok, I have no idea why my mind is not as confident as it should be about the answer that I am almost certain of.

But, I am getting older and it's best to check rather than make "stupid" simple mistakes.

So, I have built a simple 2nd order crossover to filter my Lowther PM2NKII full range srivers at 7,700 Hertz. Then I use a Dipole RAAL Ribbon tweeter 1st order crossed over at 9,000 Hertz (I will be trying a 12 db per octave crossover on the RAAL soon)

All of my crossover Inductors and capacitors are Duelund cast copper types. I have the Inductor and caoacitor for the snd order 7.700 Hertz filter to the Lowthers Velcro'd (really strong industrial stuff) to a slad of Baltic Birch Ply Wood just big enough for the two parts on each slab of wood. I then Velcro'd the crossover slab to the Open Baffle adjacent to the Lowther (the big Duelund cap to the RAAL is seperate and adjacent to the tweeters).

Here is whbere I am loosing my limited IQ. I have the positive Audience Au24e speacker spade junctioned together with one lead out wire from the Duelund Inductor. The other lead from this Inductor is cnonected to the negative Lowther speaker teminal (180 degrees out of phase for 2nd order crossovers, right?)

I then connect the black (negative) AU24e speaker spade to the red/positive Lowther terminal directly.

Now for the part that I am stupid about. I then DIRECTTLY connect the right and left Duelund capacitor leads to the red and black binding posts on/of the Lowther PM2MKII drivers.

I know that the crossover configuration is correct, but does connecting the actual speaker cable connectors (well, one Inductor lead) and the capacitor leads directly to the drivers' binding posts simultaeously (at the same time) cause the capacitors not to do their job as they would if all was connected to lugs on the wooden crossover's slab and then seperate leads then ran out to the Lowthers binding posts?

Is the 2nd order crossovers' capacitor doing it's job connected directly to the + and - Lowther binding posts at the same time as the speaker cables?

I told you that it was a stupid question. I apologize in advance and ask that you be as kind as possible with your response. Thank You.
