Best speaker between 15K-35K

Tvad, a sub is not necessary with the W/P 7's. The bass is lightening fast, smooth, deep, and as tonally accurate as any speaker I have ever listened to. The addition of a properly set up sub, the watchdog in my case, appears to augment the entire range of sound, not only the bass. It is a subtle difference but one that can be heard and felt. It is not necessarily more bottom end, but the sub captures the ambient bass line in singers voices, strings, instruments, etc. for a fuller smoother all around presentation. It is not that the W/P 7 in particular is missing anything, any speaker system will benefit from this. I auditioned this set up in the same room with the mega dollar X-1's and I preferred the WP 7, watchdog combo. The X1's needed a larger room to sound their best.

..i would also include the piega c-40s' and their little brother c-10 ltds.i have heard the majority of the speakers mentioned so far and think the piegas' are superior....but that's just to my ears. if you are indeed going to listen to all the speakers you are interested in you owe it to yourself to find a dealer and listen to these great speakers.

Thanks, Wpuppy for your clarification. It seems this hobby affords ample opportunity to improve one's system.

Adding a sub to ANY great speaker is more about ironing out room-rez bumps, right? I remember hearing the W/P 6 just before getting my Parsifal Encores. The dealer (who sold both) was puzzled that the W/Ps were coming back from a customer who preferred the Encores. But we also noticed that the Wilsons prodigious bass was overpowering the room, requiring more careful placement than the friendlier Encores.
Certainly a fine sub, well-positioned, can allow for speaker-positioning with staging in mind rather than best bass smoothness. The W/Ps clearly need a bigger room than the Encores....
Smoothjazz, your near-cubical room is REALLY challenging!
You may have to set up a non-symmetrical placement, probably a nearfield triangle, to eliminate those huge primary bumps. Good luck.

If you like the transparency and realism of electrostatic speakers, but you are interested in dynamics it's now possible to have your cake and it it too. From everything I've heard from Green Mountain Audio C-3's owners they have Quad/Sound Lab/Maggie type transparency and realism through the mid range and ultra fast/tight bass that adroitly presents all types of music.
