Subwoofer tweaks

Also try some weight on top of the unit, Tames resonance. 

@mitch2 Hahahahahahaha!!!! Well all part of the Encyclopedia Audiogalactica!!

Rythmik F-25's owner here. While I have tried and heard many a sub throughout my audio journey, here are some observations/thoughts I wouldn't mind sharing with you this afternoon. 

I prefer front firing, sealed subs.

Adjustments to the mains, as well as to the room are critical. 

Raise the height of the subs for optimal impact/ system performance.

Having subs in stereo is much better than just having one sub.

Isolation control is very beneficial. 

Never, ever underestimate the impact of IC's and PC's that go to the sub(s). 

There is no replacement for displacement.

Low excursion drivers seem to offer tighter visceral impact (not Boom).

IMO, direct servo subs are the most accurate for 2 channel listening. YMMV.

For front firing subs, they must be placed with the same precision as the mains. I am referring to toe in on this one. Not just haphazardly placed. Precision is key here. 

These are just my observations. If you want to argue, I will ignore you. That said, if you would like to discuss? I'd be more than happy to engage in a cordial conversation.

@mitch2  DOH! 

On the other hand decoupling my subwoofers a few years ago was a tweak that I found well worth sharing with -3dB subwoofer users.  

Also, I continue to recommend Velodyne's early, now twenty-two year old Digital Drive dedicated multi parameter six preset subwoofer firmware and build more than holds its own over most of today's offerings. 

I have a pair of Martin/Logan Depth i that I’ve had in my system 15 years? Before these I had a pair of Grottos. I’ve tried big brass cones from Mapleshade, Sub-Dudes, etc....settled on Stillpoints SS w/hard hats. What little resonances that are produced by a 3 opposing driver setup that cancels out vibration....are dissipated nicely with this setup. I’m on a suspended wood floor.
