Eh hem!...Subwoofers... What do ya know?

I am using a sub for the very first time and lots of usefull info here. I run Vandersteen 5a and Von Schweikert VR4 HSC in my main system, both have great bass. I got a chance to get a pair of CLSII panels and a Depth i sub, both are a first for me. Integrating the sub has been a slow process of experimentation. This may sound like a dumb question but since the sub has three drivers firing in different directions does this create the effect of multiple subs ?

thank you erik, i will look into equalization. I will also try the method indicated by davekay.

@vuongp,

The CLSII are a new experience for me. Hard to describe but the notes just seem to have so much precense and air. When I first got them and started playing them my wife and daughters came out and sat and listened, they were wowed. My current speakers are the Vandy 5a, Von Schweikert VR4 Gen III HSC and a recently aquired pair of Mezzo Utopias but the CLS panels are what made them come out and listen. The Vandys have terrific bass and great detail but they dont do well with rock. When I play jazz or blues they are great. As to the power, my main system is comprised of:
Musical Fidelity M6PRE
Musical Fidelity M6PRX amp
Denon DP80 in custom plinth with 12in Jelco and Ortophon 2M Black
Mytek Brooklyn Dac +
Nuc running Roon
Rega Apollo as a transport

I am running the Utopias in a second system with a Levinson 27 and an audible illusions pre
