Open Baffle Experience

@soix They were almost certainly the X4's, which is what Spatial has been using recently at shows, coupled with the LTA ZOTL40+ integrated.  Earlier in this thread I posted a video of that same combo at the Pacific show.  Because of supply issues and other factors, Spatial's offering is now down to just two models, the M4 and the X4.

I heard the Spatial X4s and Linkwitz LX521s at Pacific Audio Fest, and both sounded excellent. IMHO, the X4s were the best sounding speakers under $10K, and the Linkwitz were among the top rooms at the show (not my favorite, but certainly among the top 10).

I believe the best open baffle experience is a single full-range driver accompanied by a superior active sub woofer unit. This provides the best of all worlds: a cohesive sound for the majority of the musical content, and a proper power/driver size for the really low frequencies. It's the right tool for each job, and provides the greatest flexibility in choosing the amplification scheme you prefer.

It's not enough to eliminate the sonic horrors of the box - you must also eliminate the problems introduced by multiple drivers and crossover networks. My setup includes Voxativ full-range drivers and a 300W REL sub that reaches below the range of human hearing. I've used this with everything from low-watt 300B SET amps and modest power EL34 amps, as well as higher power solid state amps. Sound quality is extraordinarily clear, transparent, open and realistic. Result is an engaging listening experience. 

“Unless you are prepared to use a sub.....Open baffle are not a good Idea....I have 2 pair and rarely hook them up anymore.”

In my rooms, dual subs (at minimum) are a given… before I even decide which mains I’m going to use.

If all your running is a pair of left and right mains in an average room (with four walls, a floor and a ceiling) and the addition of a couple subs makes  the overall bass response worse…then I’d say you most certainly have either the gain or crossover frequency (or both) of the subs set  too high.

This is only if your in a typical room and therefore have the expected boundary interference.

If you move outside, or even half outside the rules (physics) change

Obviously the degree of room treatments can change the game somewhat, but I still always use both (multiple subs and room treatments) for that clean, tight punchy bass goodness…

For those of us who have owned both box and open baffle speakers at high price if that means something to Kenjit . Not just listened to them at an audio show Open Baffel do a much better job at delivering and a sonic image. Kenjit you should expand you narrow experience before you make unqualified statements.
