System Type 3

Filter Description:

Despite the fact that both drivers are mounted in the same plane and in close proximity in this system type, their orientation results in the acoustic center of the tweeter being farther away. In positions where the component set is far away (such as the rear deck), the listening angle becomes more extreme. This actually results in an increased path length to the woofer, as well as earlier roll-off of its high frequency output. Therefore, the variation in tuning between configurations A and B incorporates both the difference in angle and distance relative to the listener. Subsequently, both configurations may be used in a variety of installations that create a similar situation, but some experimentation will be necessary. As a starting point, use configuration A for a difference of 3-4” with the woofer at 45-60° (moderate delay on the woofer, with a higher order filter on the tweeter), or configuration B for a difference of 1-2” with the woofer at 70-80° (minimum delay on the woofer, moderate delay on the tweeter). In relatively on-axis conditions where the tweeter is the farthest driver, a hybrid combination between these two configurations will be necessary. For measuring purposes, the acoustic center of a speaker is considered to be at the voice coil.

Although the listening angle is incorporated into the design of these configurations, user adjustment is provided for both woofer and tweeter (WF & TW jumper groups) if further alteration of the midrange characteristic or tweeter level is desirable to suit personal taste. From the graphs below, the effect of the available active jumper settings can be seen.

Description du filtre:

Malgré le fait que les deux haut-parleurs sont montés sur le même plan et près l’un de l’autre, leur orientation fait que le centre acoustique du tweeter est plus éloigné. Dans le cas où les composants sont éloignés (comme sur la tablette arrière), l’angle d’écoute devient extrême. Il en résulte une plus grande distance jusqu’au woofer et un affaiblissement plus précoce des hautes fréquences qu’il produit. Par conséquent, la variation des réglages entre les configurations A et B tient compte de la différence d’angle et de distance jusqu’à l’auditeur. Les deux configurations peuvent servir dans une variété d’installations semblables, mais l’expérimentation est nécessaire. Comme point de départ, utilisez la configuration A si la différence des distances est de 3-4 po et que l’angle du woofer est de 45-60º (délai modéré pour le woofer et filtre d’ordre supérieur pour le tweeter), ou la configuration B si la différence des distances est de 1-2 po et que l’angle du woofer est de 70-80º (délai minime pour le woofer, délai modéré pour le tweeter). Si les haut-parleurs sont relativement dans l’axe et que le tweeter est le plus éloigné, utilisez une combinaison des deux configurations. Aux fins des mesures, le centre acoustique d’un haut-parleur est sa bobine.

Ces configurations tiennent compte de l’angle d’écoute, mais on peut faire des réglages pour le woofer et le tweeter (groupes de pontage WF et TW) si le goût personnel dicte la modification des caractéristiques des moyennes fréquences ou du niveau du tweeter. Les graphiques ci-dessous montrent l’effet des réglages de pontage actifs disponibles.
