treble and bass extension

high midrange and low treble

The J is a lovely speaker for the money, with a really convincing soundstage (I first heard this on the Snell E-II's in 1984) if the electronics are coherent.

I think the bass reflex implementation leaves a tad to be desired, though, because the J has a distinct hump around box resonance. I didn't pull out the oscillator but it's noticeable, especially on jazz string bass. Rudy Van Gelder recordings will bring it out fast, like "Giant Steps"
I like the warmth, but it's not really flat. Strangely flat and wide enclosure, also. My intuition leads me to believe that this speaker exhibits some diffraction in the HF range due to the wide, flat front baffle and the orthogonal edges.
Also, it's not as flat in the critical crossover range as something like a Dynaudio 2-way like an Audience series or a BM6. Advanced designers have really come a long way with integration. But for the time, the Snells were great.
I gave mine to a friend who loves them.
