UNBOXING M4 Ultra
M4 Ultra are packed in a telescoping lid style carton. After cutting the package tape, lay he carton flat on the floor. Each speaker has its own box. With another person, lift off the carton lid to expose the inner foam packing. Remove the base and bolts from the carton first and set aside. Remove the speaker main panel from the carton. Lay the speaker facing down on the floor (elevate at least an inch to protect the tweeter. Then position the base at the bottom of speaker to prepare to mount to speaker. Insert mounting bolts through the base and line up with female receptacles on bottom face of speaker panel. Using the supplied Allen wrench, screw in bolts until tight-do not over tighten. Stand speaker upright. Insert signal connect from speaker panel to crossover box and detailed below.

CROSSOVER BOX
M4 Ultra uses a SwitchCraft XLR for signal connection. Line up the cable mount end to the chassis mount connector and push to lock. 

HOOK UP / PLACEMENT
Install your speaker wire into the WBT input terminals observing polarity as indicated by the red or black rings on the terminal. These are multi-way binding post that accept banana, spade and bare wire connections. The ratcheting feature of the WBT helps to eliminate spade connectors from becoming loose over time. 

The high-resolution capability of the M4 Ultra require attention to setup details in order to optimize their performance. Strive to establish a symmetrical set of distances from the surrounding boundaries for best results. Minimum distance from front wall to the front of the baffle should be at least 1 meter. Further in the room may improve soundstage and other desired effects, if the location also coincides with a favorable modal area of the room. Start out with the speakers in a preferred location around 1 meter out and let them play. After 24 to 36 hours of initial break-in time, move the speakers 6 inches closer to front wall and then 6 inches further into the room from the initial position to determine if the speakers are in a nodal point in the room. Look for the area where the bass is loudest in level. Then, with the speakers at least 18 inches from the side walls, set the toe-in angle of the baffle such that it is facing your shoulder for each speaker. Use a tape measure to take a distance measurement from the front wall to the baffle in two places – inside edge and outside edge. Then, reproduce the same location with the other speaker to obtain good symmetry. As time goes by, experiment with the toe in angle to optimize the imaging and soundstaging results. Contact Spatial with questions about room acoustics and acoustic treatment possibilities. 

Expect major sound quality improvements during the first 50 to 100 hrs of play time with diminishing improvements up to 400 hours depending on music content and playback loudness. 


UNBOXING X4 Ultra
X4 Ultra are packed in a telescoping lid style carton. After cutting the package tape, lay the carton flat on the floor. With another person, lift off the carton lid to expose the inner foam packing. The full-length rigid foam packing is split into 2 parts-upper and lower halves. Lift off the top half to expose the speaker (s). With another person, carefully lift the speaker out the lower foam section. The speaker will be fully assembled. Stand upright and remove the poly over-bag. Then, carefully remove the thin stretch film from the speaker. 

SIGNAL CONNECTION
X4 Ultra uses a multi-pole Neutrik Speakon plug to terminate the wiring coming out of the speaker baffle. Insert the plug into the female Speakon jack located on the top surface of the aluminum crossover enclosure. ** Important** Turn the plug clockwise until it locks with a clicking sound.
