Hookup

Your speakers are furnished with high quality five-way type binding posts. You may choose to utilize

spade lugs, banana jacks, pins, or bare wire. It is important that the positive and negative leads do not touch. If

you use bare leads, be sure to twist them tightly and insert through holes in such a manner that they do not

fray or short out against each other. Good connections are important, so make sure any ends are tightly

crimped and preferably soldered to the wire ends. Speaker wires should be kept as short as possible, (long

wires add excessive resistance and color the sound.) The use of quality wire is recommended. Audio

Concepts, Inc. stocks and recommends DH-Labs cables. Make sure you hookup the speakers in the correct

polarity. The red (positive) terminal on your amp should hook up to the red binding post, and the black

(negative) terminal should be connected to the black binding post. Keep this the same for both speakers in a

stereo pair, and all three front speakers in a home-theater setup. A way to check the correct polarity is to play

music with a lot of bass. The correct hookup will yield the greatest amount of bass.

Positioning your Talisman

Placing the speakers in your room

As mentioned, the proper placement of speakers in your room will easily improve the sound. Because all of

our rooms and tastes are different, it is impossible to specify a “correct” placement. Instead, let us present you

with some acoustical facts, then you can optimize placement in your room.

It helps to visualize sound waves as behaving very much like water waves. The sound we hear is made up of

two types of waves. Direct sound waves come right from the speaker and are not changed in any way.

Reflected waves come to us after bouncing (diffracting) off the speaker enclosure itself, or walls, ceiling, floor

or furniture. If you want to see how much these reflected waves affect the sound, move your speakers outside

and hear the difference.

Sound waves come in different lengths; the lower the note, the longer the wave. Extreme low frequencies such

as the lowest organ pedal notes are over 60 feet long! If your room is not big enough, the wave can’t develop

fully. But the biggest problem with bass notes is the phenomenon we call standing waves. In effect the waves

more or less “pile up”. This creates big peaks and dips in the bass response. If you put a certain frequency

through the speakers, you can usually walk around the room and find places where it is very loud, and places

where you perceive virtually nothing.

Just as the room affects the bass response, so it affects the mid-treble sound of the system. In the mid-treble

range, the sound waves are shorter and have peaks and dips, most of the affects (peaks and dips) occur from

enclosure edges, furniture, walls, or the floor. The Talismans present the deepest image when placed away

from walls and furniture. The shorter wavelengths of the mids and highs are more easily absorbed than the

longer wavelengths of low frequencies. This is why a bare room sounds so harsh compared to a room with a

lot of stuffed furniture, carpets, drapes, etc.

An ideal setup for sound would be achieved if you could:

• Choose a room with width, height and length dimensions that are not multiples of each other. (A cube

would be the worst!) Good numbers might be something like, height = 8 feet, width = 15 feet, and

length = 26 feet.

• Choose a room that has an irregular shape, non-parallel walls cut down on standing waves.

• Place the speakers so that the woofer cones are at irregular distances to the floor, walls and ceiling.

This can be difficult. Use a tape to measure the distance from the center of the woofer to the room

boundaries. Move the woofers around till you have cut down on the number of related distances. (You

don’t want distances like 12 and 24”, but more like 12 and 22”). Use the distance from the woofer to

the boundaries to increase or decrease bass output. Sticking the speaker in the corner or close to

walls will give more bass output than putting the speaker out into the room. You can use this to get the

best balance between bass output and upper range output.
