System Setup

The M9500 systems are modular, each consisting of a stack of three separate enclosures. The larger of the bass enclosures are placed at the bottom, and the high-frequency/horn modules stack on top and are aligned by the screws that protrude on the bass section. The smaller bass modules are placed on top of the high-frequency modules and are similarly aligned.

We recommend that you do not assemble the M9500 systems until you have determined their best location in your listening room or control room. In general, the listening angle for best stereo imaging should be in the range from 45 to 60 degrees and the loudspeakers should be placed no closer than about 25 or 30 cm (10" or 12") from the wall behind them. Sidewalls should be somewhat farther away, and the loudspeakers should be toed inward toward the primary listening position. The room itself should be quiet, well-damped, and free of obvious ﬂutter echoes or standing waves.

Connect the loudspeakers to the networks using the cables provided. Note that there are different cables for high- frequency and low-frequency hookup; they cannot be intermixed. For positive contact, insert the Speakon® connectors and turn them one-eighth turn clockwise.

Electronic Options

Your next concern is the ampliﬁer/ loudspeaker operating mode. The various hookup options are shown in Figure 1. We will describe each of these options:

Option A, single full-range ampliﬁer. This mode of operation requires a relatively large, high-quality amplifier capable of delivering up to 800 watts per channel into 4-ohms. Note that all sections of the network are connected in parallel with the straps provided.

Option B, bi-wiring.In this mode, identical power amplifier sections are fed full-range program; one ampliﬁer is connected to the high-frequency portion of the system, and the other is fed to the low frequency sections in parallel. Many users will use a large stereo amplifier to drive the low- frequency sections and a smaller one for the high-frequency sections. Make sure that the stereo amplifier used for the paralleled low-frequency sections can deliver the necessary power into 4 ohms.

Option C, tri-wiring.This mode of operation is similar to B, but with each low-frequency section driven by its own ampliﬁer. In this case, each low-frequency ampliﬁer section will look into 8 ohms.

A, single full-range ampliﬁcation; B, bi-wiring with two ampliﬁers; C, tri- wiring with three ampliﬁers; and D, biampliﬁcation with external electronic dividing network and separate high- and low-frequency ampliﬁers.
