This is an.old thread I came across but I must chime in. I recently bought a WIZZY 12 M-line & am impressed. Vintage sound? The modern sound is associated with the Klang & growl of round wound strings, & the Wizzy 12 is quite transparent with its highs, in spite of maybe being down -3db @ 12k(?) I wonder if that eased, open, high end is a result of having no crossover?
Anyway, it has a fullness & roundness to it that complements & fattens out the sound of my light gauge, round core boomers (always pristine, because I wear guitar gloves).
My other cab is a Euphonic Audio cxl110 which has tight, punchy, well defined transients. (I'm sure a cxl12 is better, but 50lbs & so hard to find? Together they sound quite good,. I also have a Markbass122 Ninja Richard Bona Signature Cabinet which in my opinion is the best cab pound for pound. But I'm getting rid of it. I'm going modular with smaller cabs that aren't yellow & line green.
What's inspired me to go modular is that on small narrow stages it's better to disperse the sound on both sides of the drummer where everyone can hear the bass, & no particular band members are blodgeoned, or overwhelmed with boominess. (Including me!) Sadly too many drummers these days can't keep time without leaning on the bassist as a crutch. (Also, comb filtering isn't a worry. Name bassists play through PAs on both sides of the stage all the time.
I'm also prepared to employ these EA cabs for PA use, running a line from a small mixer into the return section of an effects loop. That was inspired by my former employment with a guitarist who used a 100 watt Peavy keyboard amp as his personal vocal/acoustic guitar PA. No feedback issues with the amp behind the group (no need for a monitor) At low levels you wouldn't know he was miked it was so pure & crisp. Playing more electric, rowdy, music at bigger venues, & at levels with our drummer violently pounding away, that cheap piezo tweeter sounded pretty harsh, but didn't blow. CS @ Euphonic Audio told me that the compression tweeter & whizzer cone lack the type of unpleasant resonant peaks that piezos have & should be much smoother. (I thought it was just distortion)
I haven't gotten a new gig yet & will be woodshedding for some time. But I just ordered a Mesa Boogie WD800. I'm sick of amps failing, & because my Wizzy 12 is a 4 ohm cab, I will be having to drive both the 8 ohm CXL 10 & Wizzy together at about 3 ohms.
