Yeah, I've been really turned on to Bose only because I am close to a bose dealer. I didn't know much about it til 6 months ago. I was a skeptic, but I've come around and I think for most of the church installs we do, bose works QUITE well (we haven't had complaint yet)
In response to "wide spectrum" of brands. Again, the point is to sell Bose speakers out of the bose dealer ship. Bose makes a WIDE variety of speakers particularly in the LT series. Bose even will spec out rooms for the dealers free of charge. They can even virtually create the sound in the "auditioner" system. If you don't like the sound, bose will take out the installation and refund. It's Guaranteed when it's installed right.
BTW I do like other speakers, I've had ramsa's, JBL, mackie, and carvin's I like the sound, but I love the way the L1's throw sound farther then a standard approach. Not to loud in the front, not too soft in the back (or at least more so then standard speakers).

Bose do not "throw" the sound any further (or less) than other loudspeakers. You cannot "throw" sound.
Standard speakers (as you call them) do not throw less than Bose.
For what it is worth the chuch install market covers a very wide range. If you have never installed a system that is over 30K (as you state) then you are not doing very large rooms. We do a a fair number of churches in that range and many in the several hundred thousand range and all in between.
It just takes the right product for the right job.
As I said we used to be a Bose dealer and used the MA12's successfully, untill Bose decided to screw us and allow an unlicensed/unqualified person to get the product at cost and steal a job that we worked hard to get, did demos etc. 
So we no longer sell any of their products-we have other products that do the job. 
Just wait till you get screwed-then you may think differently-not about the product, but about the company. That is the grip that many have.
Can I have some more talent in the monitors--PLEASE?

There is a regular over on Harmony Central called "boseengineer" who is a fairly respected member of that community. Their product remains unexplained to say the least but it is the way he is patient and takes the time to try to answer people's questions that buys him that respect.
I think the most interesting part of your analysis so far is your observation that the drivers degraded so quickly. I'm generally familiar with this happening...over a longer period of time...as I have worked with and repaired various systems (non-BOSE). Worn out drivers will often cause reduced sensitivity, phase issues and possibly acoustically skewed crossover points (in a multiway system).
The weirdness you heard could very well have been phase differences between all those drivers, since they are in the same passband and perhaps each deteriorating on its own.
That's too soon though. Something's not adding up (no pun intended).

I agree Chris.
The time factor does not make sense.
If we extend the time frame to months or years the worst case I have seen is the cone mid range in the JBL L-100 and all the similar designs that use the small cone tweeter, the 5’ (about) cone mid and the 12” “White” woofer.
I came up with a complete 3-way 2nd order xover for both the ‘In line” and the models where the tweeter is off to the side.
I was going to make Millions…or at least become famous. The crossover did not cost a mint, gave a flat response and most important, sounded like a definite improvement to the owners.
…but, every used mid range I tested measured different. And not by just a little. The SPL was all over the place. So my designs were toast unless you bought new drivers.
Going back to the Bose and considering the short time frame I will bet some active electronics is cooking.
Also how much compression are you using (if any) before it goes into the stick. I suppose the DX 2496 setting for dynamic EQ could be considered such.
I would have to tear it apart to have a shot at finding the problem. Take all the electronics out of the stick and have direct access to every driver separately. Measure the transfer function from the input to each driver, unhook it there and use a 8-ohm resistor for a load.
See if it is a driver or electronics problem.

All I know is I've lost a few club gigs to these damn things. Bands that don't bother to send out a new rider saying that they are all Bose now.
Although there is a jazz group that has a regular gig at our club that makes them sound ok. No hi and no low that's for sure. I've been trying to convince them to let me do a live surround thing with their 3 bose towers and my house system. I'd put one behind the drum riser and two in the house pointed inwards and run them off auxes. This is modern acid jazz type music with no vocal. I'm thinking that this may be the only use for these damn things. The concept of everyone in the band having their own PA is rediculous. When was the last time you heard a band with perfectly ballanced stage vollume?
|
I would think these things would make balancing on stage more of a problem rather then blaming musicians who do not know how to balance their own stage volume. I am old enough to have worked with quite a few bands that knew how to do that. I hope they are still playing. They were all easy to mix and a joy to listen to for everyone in the house.

I keep telling everyone, I'm not a Bose Dealer, I get NOTHING from Bose, I just happen to install a lot of Bose Products and am trying to be helpful. So please, once and for all, get off my back.

Tyler,
You'll know when I get on your back, but statements like the one you wrote below aren't helping your case at all.

And just so you know, we consistently undercut the competition. Our markup is only 20% Yes there are jerks out there, but our company isn't one of them.
If you are in the area sometime you should check out some of our installs

Tom Young,
I don't know the flavor of the Koolaid. I refuse to drink it.

Unlike many new folk here who do not bother to reply in proper sequence, I do. My reply was in response to (targeted at) Mr Lunceford, who wrote (or rather: copied) the publicity bio of Amar Bose.

Here is a Bose install in a "large room" that was surely over 30 Grand.
Bose played a pivotal role in ensuring that clear, intelligible sound was delivered to several of the Olympic stadia in Greece, including the main Olympic Stadium in Athens. Bose were involved in a total of nine projects, all of which were completed within the deadlines imposed by the Olympic Committee. The Bose system designers were fortunate to have the tools and technologies that are unique to Bose available to them during the planning stages. Using Bose Modeler design programme software for all venues, and the proprietary technology of the Bose Auditioner audio demonstrator for the main Olympic Stadium in Athens, the Bose distributor in Greece, Audio Group Greece BV, was able to produce an accurate acoustic model of the space so that key sound parameters could be predicted.
For the Olympic Stadium, the use of the Auditioner audio demonstrator, a U.S. patented system that is comprised of a dedicated listening station and software, enabled the designer and client to hear an accurate representation of the sound system solution. This was done prior to any product installation into the real space, thus reducing the possibility of the wrong solution being finally installed and ensuring that all products are positioned and aimed correctly for optimum sound coverage. Amongst issues that had to be addressed were speech intelligibility, sound coverage and sound pressure levels.
The Bose Panaray LT family of loudspeakers were considered the best choice for the larger Olympic stadia, as they deliver extremely tight pattern control in the mid and high frequencies, making them suitable for use in multiple loudspeaker arrays, long throw distances, and venues where high SPL speech and music are critical. The Panaray LT loudspeakers were combined in Greece with Bose Panaray 502B Acoustimass bass modules for low frequency support.
In the smaller venues, such as the Cycling Velodrome and the Tennis Arena, Panaray 802-III loudspeakers were utilised. The smaller size of the 802s allows them to be mounted at lower levels without restricting the spectators' view of the games.
All of the Bose systems utilised in Athens, from the rugged Panaray LT to the more compact 802 and 402 loudspeakers, are built to withstand challenging environments, including outdoor arenas and wet or humid situations such as swimming pools.
In the Olympic Stadium, the main system, consisting of 54 Bose Panaray LT loudspeakers and 44 502B environmental bass modules, was organised into 26 separate clusters. Each cluster has one or more Bose LT speakers and either one or two bass modules, aimed and positioned towards the spectators as well as the central athletics areas. A special canister to which the speakers are fixed, allows for easy installation and maintenance.
Under-balcony areas are covered by Panaray 802-III loudspeaker systems in 51 stacked pairs, carefully aimed to have the maximum uniformity of coverage. The whole sound system is powered by 90 Bose 1800-VI amplifiers.
Elsewhere at the games, a variety and combination of Bose products provided coverage for the cycling velodrome, tennis, rhythm gymnastics, table tennis, swimming and volleyball.
