Buy Bose 901 Speakers

Bose separated demo rooms was a brilliant tactic to also avoid having their products directly compared against their competitors, especially those like Klipsch that often had higher sensitivity and would play louder at the same volume level when doing A/B testing. Years later, Bose would do nearfield 5.1 cube demos at department stores like Best Buy which gave the impression of big sound and dynamics by putting the listener in close proximity to all of the speakers.
Crossover Design:The Bose 901 were famous for having no cross-over. Later versions had all nine speakers wired in series to give a 9 Ohm impedance speaker. Since the drivers in this project are 8 Ohm, they are laid out in 3 parallel sets of 3 drivers in series. This gives us an 8 Ohm speaker where each driver carries an equal part of the load.
I would be very interested in a Bose 901 design, but with a coaxial speaker. Lets say 6 inches with a .75 inches tweeter at the center. Kind of like the ones used in KEF speakers. This could extend the frequency range of the speakers.
Also, it is important for me to make clear I listened to these in various configurations (toed in, toed out, against the walls, away from the walls, etc). I also listened to them in my downstairs living room so I could position them close to the front wall (which is about 20 feet wide), per the manual I showed above, to see how much effect the near-wall placement mattered. While it did change the effect of the soundstage, for the most part, it was the same result - tonally - I had in my main listening room upstairs. I always try to listen to speakers in different settings to see if one is more suited for a particular speaker and in this case the difference was more minimal than I expected. Obviously your mileage may vary depending on your specific setup.
I know a lot of people want to get their audio system sound like they are at a concert. The problem is that concerts don't have really good room acoustics or sound systems. Obviously, if the recording is a live recording, we hope that it sounds like we are at the concert, but having the speakers basically rely on bouncing audio from the back as the main source is actually bad. Some people like omni directional speakers like MBL, or others that are simlar in design, but they don't rely mostly on bouncing the sound from the rear. With the 901's, you are actually listening to what you want less of, reflected sound.
When companies like ASC and others work with a client to measure room acoustics, they work with Articulation measurements of the room and they measure the direct sound compared to the reflections and they want to create a natural room sound rather than having it too dead, too live where the reflected sound is as loud as the direct sound coming from the speakers.
One thing to note. When you walk into a Bose dealership or Bose Store, don't let them use those CDs that are produced by BOSE. I talked to a dealer that carried BOSE for a short period of time and they explained to me that BOSE produced demo CDs that were mastered to sound good on BOSE systems, but when you listened to the same CD on another, they sounded like crap so those demos they use to sell the speakers mislead the consumer because most of the recordings you listen to weren't mastered specifically for BOSE speakers. The local dealership that told me this doesn't carry BOSE anymore and the only reason why they carried the line is they got a lot of people asking for BOSE because of BOSE marketing and they seccumbed under the pressure of customers, and in the process, they got ribbed by their higher end customers like myself, but in the end, they dropped the line as people would actually walk into a higher end store and once they started listening to companies like Paradigm and others, they became disinterested in BOSE and then sales started to wain.
Best advice I can give someone is use your own CDs, and go to a variety of audio stores (not the big box stores) and start REALLY listening to a variety of speakers, there are plenty of really good products on the market that walk all over BOSE. Paradigm is just one of many, there are Martin Logan, and many other small companies that make nice affordable products these days. If I wanted the omni directional sound, but couldn't afford MBLs or something in that price range, I would be looking at Martin Logan, Magnapan and a few others that sound so much better than 901's.
On Feb. 27th, 1999, ZBT had yet another successful theme party. Thetheme this time: Pimpz, Playaz, and Hustlaz. I thought it was a fun,very late 90's theme, and a good excuse to get way over dressed. =)I've been DJing parties more often lately, and this one was noexception. Most of the photos you see here are related to my DJexperience at the party. Aside from having tons of dressed up, deckedout dancing party people, I had my own dose of excitement from theold, failing Carver amplifier we have powering the Bose 901's. In apre-party sound check playing a remix of Sneaker Pimps Spin Spin Sugar(from Becoming RemiXed, track 4) that is really bass heavy, theamplifier overheated (even despite the beefed up cooling I had justinstalled) and also blew its fuse. Tom Cleary and I had to crack itopen, cool off the thermal fuse, and replace the main fuse (the trickwas finding an MDC-12 fuse at 10PM on a saturday! that's a whole otherstory, anyways). The main fuse blew out so hard that its contents hadmelted out, making it quite a trick to extract. After fixing that, weput the unit back together, and we were rolling just as the guestsstarted coming in. Unfortuneately, the Carver amp failed again duringthe party (!), but luckily, our homebuilt powered subwoofer (built byShamik Das andAllan Lum, based on the Bose wave cannon design--they took the classat MIT taught by Bose, so they know the physics of the speaker) madeenough noise to keep everyone hopping on the dance floor. In themeantime, I was scrambling around the DJ stand with a bottle ofquick-freeze spray in hand, trying to reset the thermal fuse. Luckily,we were back on-line in about one minute, and only a couple guestseven noticed. From that point on, I cut all the bass going to theCarver and just pumped a lot of treble to give the illusion ofloudness (psychoacoustics at work!), and tried to put as much bass aswe could into the wave cannon. It worked, and after setting up somemake-shift backup speakers, the party went smoothly from then on. Somuch for the saga of the DJ. Anyways, here are some pictures from theparty.
His privately held, 29-year-old company sold $450-million worth of speakers in fiscal year 1993, and has 15 international subsidiaries. Based in this suburb 23 miles west of Boston, Bose speakers have been best-sellers this decade in the United States, Europe, Japan, Canada, and Australia, the company says.
More than 80 percent of the sound that listeners hear during a concert reaches them after being bounced off the ceiling, floor, and walls, Bose says. Unlike conventional speakers which aim sound forward, this loudspeaker, consisting of a pentagonal enclosure housing nine small speakers, radiates most of its sound from the back. Only one speaker aims directly at the listener.
In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers. 59ce067264
