Thiel Owners

It would be interesting to hear how a Thiel SmartSub fits into your query.
I am a big proponent of REL subwoofer. Happy Listening!

Oblgny, I'd suggest trying the 40 Hz setting on Thiel's eq and using the sub below that point. This might increase the dynamic range, and "ease". Though the dynamic range of the bass on the 3.5's isn't it's strongest point, overall the Thiel 3.5's stereo bass w/ eq  provides better bass than many subs. So much of this depends on your  amp and especially your room.

Unsound...
That's what I was thinking more or less as well. I doubt I'll do it because I think the 3.5's bass is damn good as it is.  Just figuring if I have the sub....   Boredom!

Jafant...
I like Rel too.  Had a couple in the past.  

I have noticed that leaving the equalizer out completely suffers everything on the speaker. Gonna s'periment!

First I'll try with the eq set at 40, then remove it from the chain. Vedddddy interesting...
