M Series models come conveniently packaged in a telescoping lid style carton. After opening the package, two people should remove both speakers from their separate boxes (M3 Sapphire each have one speaker per box) before lifting off the foam packaging layers inside. To protect its tweeter, lay this main panel flat on floor with an inch of clearance underneath it to ensure safe unboxing until secured by base bolts provided within the original package. Secure the base at the bottom of your speaker before mounting. Ensure that you fasten it with bolts and connect them to female receptacles on the face of your panel using an Allen wrench - just avoid over-tightening for best results! Stand up your now fixed speaker, then insert a signal connection from its panel into one end of a crossover box per instructions provided afterwards.
Securely tucked around the tweeter heatsink for safe transport, easily connect your tweeter leads by matching up their red plugs with the corresponding dot on the speaker.
For a strong and secure connection, M3 models feature multi-pole Neutrik Speakon plugs that must be inserted into the female jack on top of the crossover enclosure. For an even stronger bonding process, make sure to turn the plug clockwise until it locks with a clicking sound for confirmation. Alternatively, signal connection from an M4/M6 version is achieved via SwitchCraft XLR; simply line up cable mount end to chassis mount connector and press firmly in place - allowing your speaker's wiring power through securely!
HOOK UP / PLACEMENT
Ensure proper polarity and secure connection with the WBT input terminals - uniquely designed for multi-way banana, spade and bare wire connections. The ratcheting feature ensures that your speaker wires remain in place even after extended use!
For optimal performance of the M4 Ultra, take care to set up your speakers in a symmetrical fashion with respect to their surrounding boundaries. Ensure that there is at least 1 meter from the front wall and experiment with positioning further outwards for improved soundstage experience within an ideal modal area in the room. Give yourself some time by first setting them about 1 meter away and listening - you never know what sonic surprises await! After giving the speakers 24-36 hours to settle, it's time to find their optimal placement. Start by experimenting with two different distances from the front wall - 6 inches closer and 6 inches further away - until you reach a "nodal point" where bass sounds its loudest. Lastly, be sure each speaker is at least 18 inches from side walls before adjusting the toe-in angle of their baffles so that they both face your shoulders. To ensure optimal sound quality, use a tape measure to precisely compare the distance between two speakers. Take measurements from both inside and outside edges of the front wall in relation to the baffle, then replicate this same location with your second speaker for symmetry. If necessary, adjust the toe-in angle over time as you experiment for improved imaging and soundstaging results – contact Spatial if any questions arise about room acoustics or acoustic treatments!
With the initial 50 to 100 hours of usage, listeners can expect an impressive boost in sound quality. And with continued playback up to 400 hours - depending on music content and loudness - this improvement will remain substantial!
