More About 55 Series Subwoofers
You Should Drive Some 55s!
55 Series subwoofers are the newest line of car subs from the legendary engineers at MTX! We're fanatical about bass, and it shows in these best in class subwoofers. The 55 series subwoofer produces the most bass per dollar in the MTX lines, and takes on Rockford Fosgate and JL Audio head to head - and wins hands down!More X-max and Sensitivity = More Bass
The 55 series subs are designed on new, cutting edge, patented technologies that you'll only find in MTX brand subwoofers. Inverted Apex Surround and Progressive Suspension allow for more surface area, with high sensitivity. In combination with the Radial Ribbed T-yoke, we're able to minimize "pop-through" / 3rd order distortion at high power levels, giving you cleaner bass at high power.MTX Exclusive Technologies
Inverted Apex Surround
New surround design on the 55 and 35 series subwoofers that compresses the excursion capabilities of the surround. This design provides three major benefits.First, increased surface area; since this surround is accordian style it is not as wide as other surrounds meaning the cone is bigger which results in more air being able to be moved which translates into greater volume displacement and higher SPL (Vd=Sd*xmax).
Second, the progressive surround works with the spider to control the woofer's excursion at high power, lowering 3rd order distortion which results in better sound.
Third, uniform motion is maintained on both the positive and negative cycles of the subwoofer, unlike subwoofers with tall, narrow surrounds that snap through on the negative cycle. Uniform motion results in consistent compliance which results in less distortion and increased sound quality.
