Bose Personalized Amplification System







Bose Personalized Amplification System

Bose Personalized Amplification System 02/11/2004 01:51 PM

Ever gone to a concert where it's so loud you think you're ears will start bleeding, and in spite of the volume level you can't understand the lyrics? Dr. Amar Bose and his namesake, Bose Corportation, are trying to change all that, and change the entire amplified performance paradigm with their new Personalized Amplification System (PAS.)

Bose's approach to solving this problem is pretty radical, and at the same time surprisingly simple. It involves nothing less than, as they put it, “changing the fundamental properties of loudspeakers,” and yet the idea, once it's explained, seems obvious.

The company's new product is called the Cylindrical Radiator Loudspeaker. Two dozen or so (we weren't allowed to peek inside the units) small drivers are arranged vertically in a flagpole-like structure about 3.5 inches in diameter and seven feet high, which is set into a floor stand. The arrangement of the drivers is designed to eliminate all vertical dispersion: The sound is projected forward and in a 180° arc horizontally, but there's nothing projecting above the top of the column and nothing bouncing off the floor.

The most obvious effect is that, in theory at least, the sound is transferred to the room much more efficiently than with a standard spherical-front speaker. In fact, we were invited to walk directly toward the speaker from across a large room while a guitarist played, and observed that the difference in sound level as we approached was remarkably small, even when we put our ears right up to the speaker. Therefore, musicians can play at lower levels and still fill a space. Vocals sent through the system can be loud enough to project, but the potential for feedback is greatly reduced.


(quoted from a MixOnline article)

The Cylindrical Radiator speaker is placed behind the performer on the stage, providing sound for both the performer and the audience. This is a total departure from the traditional amplified sound system, which requires separate amplifiers & speakers for the audience and the performers, a mixing console, miles of cabling, and a sound technician to make it all work, and even then it often works poorly. The PAS returns simplicity to the idea of amplified music performances, and makes for a much more natural sound coming from the stage, with the amplified sound from each performer coming from where that performer is on the stage. According to many posters on Bose's online forum, the system is also ideal for DJ's and playback of recorded music.

This is an answer to many prayers from frustrated performers and sound techs alike, tired of overly complicated systems for small to medium-sized rooms, not to mention concert-goers who feel the need to bring ear plugs along.

Look for the PAS to show up on stage at a nightclub or church near you.

Bose Suspension System


Bose Suspension System 12/24/2004 12:57 PM

That's right. Bose.

The latest trick coming from the 74 year old Dr. Amar Bose is an active suspension system; the Bose Suspension System. It's been in development since 1980, and so far they've only got it on a 1994 Lexus test mule, but rumor has it that Cadillac may offer the Bose system as an option on an upcoming car.

The proprietary Bose suspension system couples linear electromagnetic motors and power amplifiers with a set of unique control algorithms. For the first time, it is possible to have, in the same automobile, a much smoother ride than in any luxury sedan and less roll and pitch than in any sports car. The Bose research vehicle provides superior comfort by gliding smoothly over bumpy roads and superior control by keeping the car body level during aggressive maneuvers.

When you think about it, it's not that much of a stretch for an outfit like Bose to go from speakers to automobile suspensions. A speaker is essentially a linear motor that uses electromagnetism to move a speaker coil to produce sound waves; the suspension Dr. Bose has assembled uses four linear motors that basically use the same principle to keep the car on an even keel, no matter how the driver and road thrash the thing.

We've talked about the inherent problems of sophisticated electronic systems in vehicles before, and I don't think I'd want something like this in my car... At least not until the technology has matured for several years. Stories of Land Rover suspension systems failing at high speeds and causing deadly accidents is enough to make me want to stick with plain old shocks and struts.

The January print issue of Motor Trend has a brief article on it, but a more extensive writeup online, complete with a video of the test mule in action. In the grand finale, the Lexus actually jumps over a 2x6 on edge at 35mph!

At $300, the SoundDock is more expensive than competing systems. However, it's currently the best sounding of the all-in-one speaker systems we've tested, and its uncluttered elegance and ease of use make it an appealing offering for those willing to plunk down the change. By Dan Frakes, Macworld

Bose SoundDock for iPod


Bose SoundDock for iPod 09/27/2004 09:04 AM

bose_sounddock.jpg imageThere is a certain poetry when Apple and Bose team up in offering the new SoundDock digital music system. It's basically yet another dock with a pair of speakers attached to it, something we're not in the least opposed to, but it does set one to wonder what happens when blowhards like Bose work with blowhards like Apple to "elevate your iPod listening to a whole new level."

Do both Reality Distortion Fields cancel each other out? Is it possible this $300 set of speakers is actually a good product? I'm not sure I'm man enough to find out.

Personalized Radio... Based On Your MP3s


Personalized Radio... Based On Your MP3s 08/02/2004 01:39 PM
Wired News is running a story about Last.fm, an internet radio station that goes a bit beyond most internet radio stations in its ability to personalize what you hear. While most stations require users to rate a variety of songs to come up with a profile of what you like, Last.fm uses plugin Audioscrobbler to comb your hard drive for music files and build a profile of what you like. It will then create a personalized station based on what you already had on your hard drive. It also includes other features, such as the ability to listen to other users' radio stations. The company is perfectly legal, having paid for online radio licenses from the music industry. What's interesting is the company's business model: they're selling market research to record labels. What the article doesn't say is whether or not this scares off any users who don't like the thought of a list of what they have on their hard drive being sent to record labels (though, obviously, Last.fm isn't sending lists of specific hard drives, but more aggregate data). Either way, it sounds like a cool use of the technology for those who don't mind sharing what they're listening to.
