2wq filters: what do you recommend?

I forgot to mention that I agree the M5 and x-2's for the 2wq's are 80 @ -3db but I think the new 5A has been moved up to 100hz @ -3db.

I am thinking of taking your suggestion and building my own crossover. I have a few specific questions.

1.TNT says that the .01 (or .013) Dynamicap is available in both loudspeaker and electronics version. Percy has it in electronic version only. Which is the appropriate one? (I am guessing electronic)

2. For solder, Wonder or WBT?? WBT has a lower melting point and would it be safer for the Dynamicap?

3. For wire, wonder wire 19 ga. Any other suggestions?

4. For the ground for the RCA connectors, Does it go from the ground of the output RCA to the ground of the input RCA-or somewhere else? Is Wonder Wire OK here too?

5. Wrap all in heat shrink. Meltable, adhesive lined or polyolefin?? What does 2:1 or 3:1 mean in describing shrink wrap? Is that the amount it can shrink?

Thanks very much in advance and I hope others contemplating the same venture will benefit from the answers as well.

Use the electronic version. The Wonderwire is fine. I personally use the WBT solder. The wire goes from the outer part of the two male an female rca connectors.
The numbers on the strink indicates the ratio it will strink to when heated. The metable gets awfully hot. I would use one of the others that don't take as much heat IF you want be flexing it. Otherwise the metable is better.
