What would sound best a Memphis 10" PR104 Single coil 4ohm with a Coustic 800S or PR104Dual coil 4ohm with Coustic 800DB?

 

The vc configurations has no effect on the SQ of the speaker, but different vc configs may have slightly different t/s parameters. My guess is that it will be not be a noticeable difference, if you had both side by side, and were listening and comparing both.

 

What does different t/s parameters mean?

 

Thiel-Small parameters. Do a google search.

 

I went with a 10inch Memphis powered by a Memphis 170watt amp in an AE enclosure. Outstanding and, from what I could find out, well rated. Good gear for a good price. Total price with install was 300 bucks.
