Of course they were! The WEM gear was great but rarely spotted over here. Our first upgrade in PA after using a pair of Silvertone 610 guitar amps was a Acoustic 870 board (believe that model number is correct) and a pair of matching columns. We were in heaven with those and even when we moved to big horn loaded boxes used them for monitors. They served us well and always sounded great. It's amazing what we had to work with and made work back in the day:) I remember one of the "big" local bands using big weather horns and a Bogen power amp. Things have evolved, but vertical arrays are back to stay I believe. This is a vertically aligned 4 x 8 cab that handle 700 watts and weighs 40lbs.

Oh my. I didn't notice the date:)

Hey Danny! Thank you for the mention. The RS410VT transports easily in the back of a compact car, top recessed bar handle and built in wheels allow it to roll wherever you're headed and the side handles are ergonomically placed and perfectly balanced so that the cabinet self levels for sliding it across your back seat. I still make a "traditional" rectangular 410 but the vertically aligned is superior in every way. Off axis response is excellent, the footprint takes minimal space on the small stages we all end up on some times, and it's not blowing past your knees. And, it's light.

Duke at AudioKInesis is doing some. I have a prototype that's been in testing for the last month that is taking 800 watts. The early Berg 112s still hold there own and sound wonderful albeit heavy. I agree to your observation re the design approach similar to or sharing components that are ProAudio/FOH focussed. But there are drivers available now that are voiced for bass guitar that are exceptional and offering a lot more options to designers/builiders and players.

The Kappalite 3012LF is a wonderful FOH/PA driver. It is not IMHO suited for bass guitar. If you choose to load a cabinet with an additional driver of different size to enhance/add midrange you are venturing in to a place of diminishing returns. Choose your driver carefully for it's application and voicing with sufficient bandwidth (and there are many available) and tune your cabinet carefully (if you are porting) If you want more "woof" use a rectangular vent, more hifi..a duct. If you choose to mix drivers you must consider sensitivity. If you 15 or 12 is 98db your 5,6, or 8 should be the same. Then you need to either electronically align (as EAW, JBL and Meyers began doing in the late 70s early 80s when they were building boxes with mixed drivers) or mechanically align them in your cabinet with the backs of the voice coils aligned. In the 2000s we're back to where we were in the 60s and rightfully so. Line Array. Again, just this old musician/engineer/designer/builder's humble opinion.

There are some 112 "super" cabs that can sustain 600 watts comfortably and remain pretty fast unlike cabs using PA/FOH drivers that do what they are designed for but are not IMHO suited for MI/bass guitar use. Also, there are new 15s that are like D140s on steroids. They are taking 4X the power and venturing up into 12 territory while maintaining the "old school" foundation that began our love affair with them back in the day. A 25lb 115 is powerful and very portable.
