5. ever different placements will influence the sound One basic rule is to place the subwoofer together with or near the front system especially important if the front loudspeaker also recreates bass frequencies as this will minimize the risk of phase eliminations in the room For some combinations of rooms wall types it may be advantageous to place the woofer near a wall however this may also yield unwanted reflexions hence a dirty sound How near the wall you place the subwoofer is a matter of balance Never put the subwoofer inside a cabinet the amplifier need to be cooled by circulating air Cables Finally Try to keep them as short as possible By its electrical parameters a long conductor will have a bigger influence on the sound than a short one It may also work as an antenna and thus receive various signals that may become a constant noise in an active subwoofer Make sure that all connections are clean and not oxidated All connections should be mechanically stable both power signal and loudspeaker cables Signal cables should be separated from other cables Please remember that good sound is a matter of taste so you have to experiment to obtain it We wish you the best luck Mounting Mounting alternatives Overload The initial playing time The XTZ 99 W8 16 is best placed standing on the floor However it is fully possible to lay it down without affecting the sound Driver and bass reflex ga
6. igh precision in the sound We have equipped the XTZ W8 16 with a very powerful amplifier with a big cooling flange for effective cooling The terminal connectors are gold plated and very solid To achieve a high power and a long durability the amplifier is built with a large ring coil transformer large electrolyte capacitors and has MosFet transistors in the power amplifier The active amplifier also provides a variety of possible adjustment possibilities unable to obtain using a passive filter This includes phase frequency high pass filtering volume etc By using these settings the main amplifier is relieved and thus only takes care of the midrange and trebble Thus it works better and the risk of damages on it is lowered Preparation Unpacking the subwoofer Accessories Carefully unpack the speaker and pay attention so you don t brake anything If possible save the carton box for future transportations If there should be a damage on the loudspeaker please contact your retailer 2 bass plugs found in the bass reflex gates User s manual Practice of sound Installation and placement tips In which room do you achieve the best sound Reflexions Amplfication of bass frequencies Furniture Room dimension Placement of the subwoofer This chapter contains common information on loudspeaker placement and installation No matter how good the equipment is in the wrong listening environment it wil

8. l inevitably sound bad There are some basic rules concerning a proper loudspeaker installation Carpets curtains and soft furniture absorbs mid range and high frequency sound and this is preferable Big empty area on the contrary reflects it and produces a hard sound that may lead to a blurry dialogue Apart from coloring the sound also the perspective of the sound will deteriorate Reflexions in the room can roughly be compared to the reflexions that yield ghost pictures on a TV screen A loudspeaker that is placed near a wall ceiling or floor will be amplified in the lower frequencies in a sometimes not desirable way since it may lead to an indistinct sound recreation This amplification becomes even more obvious if the loudspeaker is placed near a corner Thus for a sound as clear as possible the loudspeaker should be placed about 30 cm about 12 inch away from the wall However there are exceptions from this rule For some type of walls rooms the loudspeaker it may be advantageous to place the loudspeaker nearer the wall read more below Be aware that furniture may vibrate and thus create bad sound at loud bass Quadratic rooms or rooms where the length is exactly twice as long as the width should be avoided since they may create unwanted resonance Since it is so hard to judge the direction of bass frequencies the placement of the woofer is not that critical as for instance the placement of front loudspeakers How
