hey
Yeah the Pioneer pro audio stuff has been about for a couple of years now, with what has to be said was mixed results originally.
As Paul said on the previous page, I'm sure many on here know the history of this style of dance stack design. Richard Long Associates pioneered this in the 70's with some of the most famous and best sounding systems of the disco era in places like the Paradise Garage in NY. Big bertha/Levan subs with the horn extensions and JBL acoustic lenses were the classic look, with little tweeter boxes hanging from the roof in various places to spread the high frequencies around.
When Richard passed the mantel was then passed onto Gary Stewart Audio who took over the same types of designs, updating the components with BMS compression drivers and such, but sticking to the same basic principals of big bertha style subs with the levan horn extensions and JBL lenses.
(There was much more detail in the history of this on both the RLA the GSA websites, with some very nice pictures of their systems and custom designed DJ booths and control surfaces etc etc, but sadly both seem to be gone now, though doing an image search of Gary Stewart Audio still brings up some nice pictures)
Gary Stewart sadly also passed away, in 2012, and I'm not sure of the exact timing of the Pioneer connection: whether Gary himself was involved in the initial designs or whether his family/business decided to licence the designs to pioneer after he'd passed to generate some extra income, but Pioneer now carry on that style of speaker design with their GS-Wave system, designed to compete with the Funktion 1 dance stack etc.
When it was released and demo'd at one of the big trade shows it got very mixed reviews, but it was a brand new system at the time and I think the consensus was that the set up and alignment of the speakers etc was more at fault than the actual boxes themselves, and it was a bit rushed out the door for the show, it just needed more work on tuning and presets.
Last summer I was on a training course with a couple of the guys working at the Pro Audio division, including the head Alex, who is an ex-Martin Audio guy (and a very nice guy at that).
Ironically he was working at Martin and one of the main people involved when English super club Ministry of Sound moved away from the RLA/GSA style dance stacks to a Martin designed equivalent with their big and well documented renovation in 2008, before finding himself at pioneer working on those same systems.
Being mostly based around dance/club music, they have a few big installs in Ibiza and around Europe, and one in LA I'm sure I remember reading as well.
