UNBOXING M4 Ultra and M3
M Series models 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.
M models use a multi-pole plug to terminate the wiring coming out of the speaker baffle. Insert the plug into the female jack located on the top surface of the aluminum crossover enclosure. ** Important** 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 M Series models 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.

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.
Rules and guidelines for our website.
Important things to keep in mind when returning a product.
Repair or replace a faulty product during the warranty period.
Spatial was incorporated in Utah in 2010. The Better Business Bureau rates Spatial with an A+ rating, with zero complaints since inception.
We do a factory pre-conditioning regimen of approx 20 hours prior to testing. Expect reasonable sound by 50 hrs and full break-in between 100 and 200 hrs. Some improvements may be noticeable afterwards.
Spatial offers a 60 day, no hassle return option on all our products.
Factory direct sales reduce the price by 40% to 60 % compared to retail shops. Speakers should be auditioned in your own room to make a valid decision, so buying direct is the best overall approach for our customers.
Due to supply chain delays, some components will not be available for extended period. We expect to resume product this fall and will announce availability when have confirmed the timing.
Over time, we expect that more manufacturers will design and produce dipole speakers, once they overcome the technical challenges involved. The performance advantages are so substantial that many companies will decide to switch over in order to remain competitive or risk obsolescence.
The Sapphire versions incorporate the a wide-band dome tweeter with more resolution and broader dispersion than the coaxial driver in the previous M models such as the M3 Turbo S and M4 Turbo.
While different in design, both series produce a similar music playback performance. The premium X models add greater dynamic range and higher output than the M Series, the X Series should be chosen in high SPL home theater applications.
30 inches or more to the front of the baffle. Additional distance can create a larger acoustic soundstage.
Yes, a substantial number of our customers have experienced excellent results with tube amps. The easy electrical load and high efficiency allows your amp to operate at its best.
Sure, if you already own a subwoofer, we recommend that you try adding it to our speakers and decide. The overwhelming majority of our customers report better results without the sub. Subs may be of use in home theater applications.
All of our models can be used in HT applications, with the X Series models preferred for high SPL applications.
Yes, the WBT Nextgen binding post accept both types.
Small room example 10x12ft, medium room example 13x17ft, large room 15x20 and larger.
Specially designed speaker drivers and proprietary techniques developed over years of research, provide outstanding bass performance as compared to conventional box designs, without being overly large.
The increased heat dissipation and long excursion features allow the M100 to play down to 576Hz for greater resolution and precision in the critical midrange region as compared to cone drivers normally used in this range.
