Better integration: sealed or ported DIY mains with sealed sub (1 Viewer)

[KyleGS]

I'll be building the KIT61 soon with the Extremis. I'm really partial to sealed designs.

I'll be running (4) sealed Dayton DVC's.

Can anyone comment on the integration of sealed vs. ported mains with a sealed sub. It seems like I read somewhere that ported mains blend better with sealed subs in general but I cannot find the link or the experience/reputation of the person.

Thanks guys.

This is pretty general but the lower your mains extend , the better they will integrate with your subwoofer(s).

If you go to the north creek speaker site, they seem to intimate that sealed mains will integrate better with a sub... something to do with the shallower rolloff?

Sealed mains with a Qts=0.707 will integrate better with any sub. The crossover should be set at the mains' f3 point.

Sounds good. I was planning on running the Extremis @ a 0.7Q design.

Personally I've never had any problems integrating any mix of sealed or ported mains, with sealed or ported subs. The key to this is using both mains and the subs that have linear (pistonic) operation, one full octave beyond the XO point
