Sub-woofer fast enough for Horns?

Luna,Just sit back enjoy your wonderful Cessaro's.
Others might disagree but I find trying to integrate subs and maintain the Mid's of a 2 channel system is an impossible feat.
I've tried this using Entec's, on Stats and Dynamic speakers and failed each time
I haven't tried this on my horns

The two primary researchers in the field of multiple subs are Todd Welti of Harmon International, and Earl Geddes of GedLee, LLC. Briefly, Welti investigated symmetrical configurations while Geddes advocates asymmetrical configurations.

I disagree. I have Wavetouch Audio Grand Teton with a pair of Velodyne SPL s2 - 10". I am very satisfied. Almost all conventional speakers don't have enough resolution and presence that all frequencies (hi, mid, low) are easily washed off with the powerful subs' physical acoustic energy (like a sonic bomb). The integration of speakers and subs is easy when speakers have the realistic presence and palpable acoustic focus.

I can't imagine a HT without subs. It will be boring! The couple of subs in hi-end 2 ch system add much excitement in music.
**Warning! Many sub-woofers in HT could hurt you and (especially) young family members' ears. I recommend bass shakers under your seats and sofa.

IMO, the sub is not slow. You are hearing and feeling the prolong vibration of the room and furniture cause by subs. That's what subs are supposed to do. Without it, the sub-woofer is no fun! The problem is your speakers which doesn't have enough resolving power.

Why not use a sub bass or bass horn? Wee little cubes with over taxed transducers and poor transients are why your not getting a good match if running horns use horns.

Rythmik F15 is the fastest sub I've ever encountered.
