Most Musical Subwoofers?

another vote for the Thiel sub

Sgr,

The SMS1 will take over all functions of the subwoofer and you will be free to experiment with it as you wish. You can let the SMS1 do its own analysis for a starting point and play around from there. The lowpass crossover frequency is adjustable from 15-199 herz. More than enough ajustability for most installations. You can daisy chain up to three subs to the SMS1 with all receiving the same processed signal or you can add multiple SMS1's in another type of daisy chain configuration with each sub getting their own equalized signal.

On the subwoofer itself, all subwoofer settings for EQ must be turned off or bypassed. The same for phase and contour settings. You will need to have the volume about 1/3 up to allow you to play with settings and make comparisons. The SMS1 will allow you to tweak like crazy. It is really easy to use and integrate, at least in my system, so YMMV.

If you are willing to spend the money I would look at the Martin Logan Descent, just as fast and deep as anything out there. They also have built in high pass filters to run your mains through for easy integration.
