I have owned Bose products since 1976 and have been using Bose Professional products for over 10 years now. In that time I believe I've heard just about every positive and negative thing about Bose products.
I recently ran across a posting by a Bose dealer that touches on some of the negative issues that are quite often heard.
I know of 3 local music equipment dealers that had once carried Bose products but decided to drop the Bose line ( or maybe Bose dropped them ) because of some of the issues that are in this dealers post.
Personally, the only problems I've had with Bose were with my first pair of 901IV home speakers (which Bose eventually made good on) and a fiesty At-Bose-Guy on this forum.
I have found the Bose Guys and this forum to be exceptional in the world of pro audio. Great service and support! Yet it bothers me that Bose has somewhat of a negative reputation in the audio community.
Here is the post made by the Bose dealer:
Bose has a long and checkered history of dissing the pro audio community and specifically consultants, who they have always felt didn't "understand" their products and that was why we did not specify Bose as often as Bose felt they deserved to be specified. The corporate personality of Bose is such that when things don't go their way they can get pretty ugly. I have had 3 concert hall projects "attacked" by Bose who came in the back door and attempted to get their stuff in with (among other things) falsified modeling data. They managed to get "all the way" with only one project and that was by giving the owners a sweetheart price. This same tactic was attempted on a number of other consultants' projects, so I never really took it personally. I just was offended that they 1) caused my clients to worry about how things would turn out, and 2) assumed I didn't know what I was doing and 3) they did not have appropriate ldspkrs for those spaces.
Bose also is almost always suing other manufacturers for the faintest hint at patent and/or trademark infringement and even went so far as to sue a reviewer in a HiFi magazine for writing a critical piece.
Their Personal Amplification System marketing scheme is simply a gross overstatement of the performance characteristics of a column ldspkr mixed with a rather cynical attitude towards live sound folks and targeted at gullible musos who would like nothing more than to minimize their equipment costs, equipment packaging size and its operational complexities. We consultants are only really concerned that churches will buy into this, frankly.
Despite all of that, I am obligated to use/specify Bose when and if their products do the job. I have no problem with this. The MA12 (which is the same ldspkr as is used in the PAS, BTW) is an amazingly effective "low-tech" ldspkr system that provides very useful behavior for some projects and/or spaces. They also happen to be reasonably priced.
I say "low tech" because while everyone else has been designing elaborate passive and active column ldspkrs with frequency shading and steerable beams, Bose simply developed a very good 2.2" driver to employ in a cloumn (with no fancy processing) and when applied correctly they work very well.
However, they should NOT be positioned behind the microphones, they cannot be used as both monitors and FOH ldspkrs and they most certainly can cause more harm than good in many spaces. Just like any other ldspkr.
I have used MA12 arrays in several church projects now and the results have been very good. I also use more expensive steerable line arrays (columns) and other types of ldspkrs when these are merited.
