Tweeters or full range speakers are normally in enclosed speaker cabinets. Building these speakers into a table near your ears cannot give you the quality of sound that headphones, stereo or surround sound speakers properly placed can deliver, thus tweeters or full range speakers are not built into these tables.

Masterpiece LCR, Portrait LCR, and Sketch LCR: 50 – 250 Watts RMS set on THX at 80 Hz crossover.

Some people can build better than you can buy. These people are either experts, golden ears, extremely well equipped, inspired, or a combination of the above. Some companies have plans available to entice you into buying their drivers: Audio Concepts, Audax, Dynaudio, Focal, KEF, and Scanspeak. Your success rate with these plans will probably be very good IF your cabinetry skills are very good and IF you follow the plans precisely. If you deviate (as everyone does), anything is possible.

In full GURPS, all those skills have /TL. But in GURPS Lite, the vehicle skills include Bicycling (which has no TL) and the missile skills include Bow (which has no TL). So we omitted the TL as being not entirely true. And anyhow, the TL penalties for physical skills are GREATLY relaxed in Fourth Edition, so the omission really produces only minor effects. I hasten to add that GURPS Lite for Third Edition did the same. It's meant to apply at "Less than 1/3 your . . .

The Table model is a simple list of wavlengths (in microns), n, k, where the wavelengths are entered in strictly descending order (short to long). GSOLVER looks for a required wavelength by searching the table from top to bottom, finding the entries that bound the given wavelength. A linear interpolation is then made on the n and k values.

This is probably the most commonly asked question on rec.audio, and also the most impossible to answer. The market keeps changing, everyone has different tastes, and no one has the time to listen to even 10% of the products available in any country. Also, many good products are only available in specific regions or countries. If you really want recommendations and are willing to listen to the opinions of others, check the past few issues of Stereophile Magazine.

Good question. First, electrostatic forces are weaker than magnetic forces. Therefore, membrane excursions are limited. Since acoustic energy is a function of the volume of air that is displaced by the membrane, limited linear displacement is compensated for by making the membrane area larger. However, this has a beneficial effect: the large membrane exhibits a more resistive coupling to the air.

J.R. will stop Mid-match actions but cannot stop the use of Pre-match cards used as Mid-match actions because J.R. specifically says it affects Action CARDS, not cards that simulate Actions.

GUI construction with Perl" is a modern treatment of what's involved in use of Perl/Tk. It specifically details how first-time Perl/Tk programmers can install Perl/Tk usefully. A made & installed perl (requires a C language compiler). You may need different versions of perl depending on which version of Tk you wish to run. A linkable Xlib (.o, .so, .a, etc.) for X-windows. Perl/Tk has been successfully built using various vendors' cc compilers, as well as with the free GNU gcc compiler.

Since GSOLVER linearly interpolates between entered values of the index of refraction, it is not possible to determine off table values. Usually GSOLVER will return the endpoint value and proceed. It is up to the user to make sure that the table values needed are available for the given calculation. Table wavelength values have units of microns, and may be entered with a text editor (of the GSOLVER.INI file), or with the GSOLVER materials editor (on the EDITOR tab). [Back to the top]

A patent has been awarded Sound Lab that describes and protects a method by which the single-frequency resonance energy of the membrane is distributed in a manner that equalizes for the loss of energy due to dipole cancellation (a problem with all dipole speakers). This development not only provides a flat, extended bass response but it also eliminates the undesirable membrane resonance peak. [Learn more]

All Harbeth tweeters are made in Norway by SEAS, the masters of tweeter design. Some models use tweeters using a formed aluminum diaphragm; some use the Excel system with the soft diaphragm. There are advantages and disadvantages to both types: the aluminum dome is highly repeatable, reasonably priced and within its operating band is very linear with a piston-like performance.

Different from conventional dynamic type tweeters, ceramic spherical tweeter is designed to have self-resonant frequency at the higher side of its working frequency range. As known well, the vibration system that has higher resonant frequency shows faster transition characteristics compared with the one having lower resonant frequency. Thus, ES103A is able to achieve excellent transient response.

If your speaker system has a flat surface on top, just place where you like the total sound best. If the top surface is not flat, place near by the speaker using appropriate speaker stand. Or, you can apply with a microphone stand hanging down tweeters instead of microphone. Yes. They work well for all; CD, vinyl, SACD or even DVD audio. Naturally, the better-recorded album gives better sound. In any case, you will see the improvement by the tweeters.

Okay, lets all think about staging for a second. You don't go to a concert and sit with your back towards the band right? And admit it - we'd all like to be right in front of (and dead center of) the band on stage true? And you'd also like to be at the right height too - like you were on the actual stage right in front of the band listening. This is the image we try and capture inside cars today and tweeter positioning plays a large poportion of this phenomenon.

The Executive Committee has selected the speakers for their international expertise. There will be : CEOs, Authors and Executive Coaches, Professors and International Experts. The speakers and their bios are presented in the Speakers section of this web site.
