How to Build Acoustic Wave Speakers (7 Steps) How to Make PVC Tube Speaker Enclosures (4 Steps) How to create your own BOSE speaker system and save a ton of money. How the Bose Wave Radio makes Big Sound. The Technology It took the team composed of Dr. Amar Bose and Bose senior research engineer Dr. William R. Short almost fourteen years to develop this state-of-the-art concept.

We all know that when a speaker is mounted in an enclosed channel or tube, the cone movements act as a wave guide, producing higher outputs than the actual output from the speaker. It was understood that by incorporating a wave guide, smaller speakers could be used for acquiring richer outputs, irrespective of the volume of the music. The actual theory is a trade secret and has been patented, and therefore all the details cannot be revealed here, but the following points can make the idea considerably clear to us, as far as the operation is concerned: At Bose, the engineers started calculating the exact area of the wave guide and the way it could be accommodated inside smaller enclosures. More technically the concept can be summarized as follows: Audiophile Tube Amps and Tube Gear from DECWARE. The Nibbelin Ultraflex are similar in sound to an open baffle but have bass with good weight and tone. In the midrange the cabinet design acts like a one-way valve (check valve) over a large band of frequencies.

Sound inside the cabinet exits instantaneously leaving little to no sound to reflect back to the driver. High band frequencies are handled by foam spheres placed inside the cabinet in a vertical line to eliminate all parallel surfaces. The actual number of spheres can be adjusted to taste. The result is simply the most non-congested sounding cabinet you've ever heard next to an open baffle. The efficiency is conservatively rated on this speaker making it a great choice with fine low power tube gear.

Tube amp friendly with reasonable to above average performance on our 2 watt SET amplifiers but electrifying on higher power. Besides the elevated performance of these speakers, their biggest asset is the smoothness and disappearing act. You may read reviews on our products here. Decware FRX2 Exotic Full Range Driver. Delivering amazingly flat response - which means "No Shout! " and more realistic sound! Imagine your speakers having such extreme speed and top-end detail that cymbals, bells, chimes, xylophones, horns, stringed instruments, drums and virtually ALL music SOUNDED REAL!

Instead of sounding real peaky like so many full range drivers, the FRX2 just sounds real thanks to the super extended ultra smooth response made possible by it's electromotive coupling technology and powerful neodymium magnet. click here 1024px high res image MODEL FRX2 E x o t i c F u l l - R a n g e Single Point-Source Driver for Open Baffle Loudspeakers 37Hz ~ 22kHz response 8 Inch driver / 94 dB 1 watt/meter a pair View Cart or Check Out We hand make these beauties in the USA click here 1024px high res image MODEL FRX2. Audiophile Tube Amps and Tube Gear from DECWARE. The Zen Open Baffle is completely unique. There is no other speaker like it.

Decware's owner, Steve Deckert, once again demonstrates radical out-of-the-box engineering! It's an open baffle design featuring a single full range driver in a tall narrow baffle. It has no crossover and no other woofers to help out with the bass, yet it has bass! If you are familiar with open baffle designs, you already know that to get any bass the baffle must be wide and the driver low to the floor (and usually multiple drivers must be used). It's quite literally like pulling perfect bass out of thin air with no woofer, no compression and no cabinet vibrations!

With high efficiency, these speakers pack huge rewards with amplifiers all the way down to 2 watts! We also have a support forum with many people who own our speakers who's experiences you may benefit from. You may read reviews on our products here. The ZOB is now being sold with the new FRX full range driver shown above! DECWARE / D.I.Y. Audio Projects. Audio Innovation - by Dan Marx Larger enclosure size.

More difficult to accurately achieve predicted results. Misaligned enclosures can result in very poor bass quality. Very accurate T/S parameters of actual driver is required. Although sometimes you can get away with using manufacture’s specifications. Driver unloading or bottoming out below fB is very common. Xmax is reached easily below fB and may cause sever damage the the driver's suspension, voice coil or cone.

Ernest Hemingway It’s goal setting season, so I thought it would be helpful to point out the pitfalls.

The dreamers have already been there.” — Robert Frost While I’m a fan of dreaming big and big, bold dreams, I’m also a fan of testing our dreams so that they really do help us in work and life. I’ve been re-thinking the power of dreams and how to dream big. I know all to well how the right dream can inspire us and lift us back up when we fall down.

Pay attention, see the connection. Imagine someone who can’t balance a checkbook. So too, with wisdom for living. How to Organize Your Brain For Better Productivity. Our minds are basically organized like human computers. They function to a great extent in much the same way. So, if we want to improve our daily productivity, efficiency and focus, we need to empty the cache of temporary “files” and reboot for our brains to allow us perform at our peak levels.

Otherwise we can easily experience brain overload with too many circuits firing simultaneously and so many programs (thoughts) working in the shadows that we often “freeze up” and cannot remember everything or simply process the information in a much slower and less efficient manner than we’d like. It sounds odd, but when you stop to consider, it actually makes sense.
