B2 Audio RAMPAGE - 12″ SubwooferRAMPAGE XM 2012 had the seeds planted for the RAMPAGE. A direct derivate from the legendary & innovative X2C subwoofer with a 5 voice coil. Although the RAMPAGE XM is based on a 4 coil platform, its performance will not stand in the shade of its heritage. In many ways, it pushes the boundaries even further. The new basket offers better cooling with improved SAFT (Smooth Air Flow Tech) & has the ability of offering even more XMAX than the previous

RAMPAGE XM

2012 had the seeds planted for the RAMPAGE. A direct derivate from the legendary & innovative X2C subwoofer with a 5″ voice coil. Although the RAMPAGE XM is based on a 4″ coil platform, its performance will not stand in the shade of its heritage. In many ways, it pushes the boundaries even further. The new basket offers better cooling with improved SAFT (Smooth Air Flow Tech) & has the ability of offering even more XMAX than the previous basket . 3.15″/ 80 mm peak to peak handled by the 315 mm / 12.4″ spiders , that are amongst the largest you will find on any traditional 15″ subwoofer (without the use of adapters), in addition the new basket offers a triple landing so you can customize the stiffness and spider size to your application.
OCAF

OCAF version II (Optimized Cooling And Flow) implemented in the new motor design has adapted the large flares from the X2C’s backplate. In addition the pole piece features a dual cooling system that leads the air more efficiently away from the voice coil. Even though the internal diameter of the coil is 4″, the outer diameter of 4.33″ makes this coil a widebody, coupled with an 8 layer tall winding, this design is made for daily torture or demo days!

The RAMPAGE XM’s motor keeps the same 11″ diameter as previous XM subwoofers, but the triple stack ferrite slugs are increased by 25%. Still we are able to keep the entire height of the motor to a mere 10% more than 2nd gen XM. With the longer Xmech, the added 10% comes into play.
Stiffness

Another tool was made for the XL composite dustcaps with embossed B2 logo. The half spherical design with wider wedges stiffens up the cone, offering greater stability, and helps keep that transient response tight. So when the bass drops its on point. Using a slightly wider stretch foam surround there’s less mechanical parts that will limit your stroke.

The Excellence of Motion Preserved
Style: Full Synthetic High Mileage, Size: 1 qt (Pack of 1), Configuration: 5W-30
In the pursuit of the ideal, where reason governs and the forms of all things aspire to perfection, the Valvoline Full Synthetic High Mileage with MaxLife Technology 5W-30 Motor Oil presents itself as a manifestation of virtue within the mechanical realm. It is not merely oil, but a substance designed with foresight, sustaining the engine as the soul sustains the body. The viscosity is measured, neither excessive nor deficient, allowing parts to move in harmonious accord, reducing friction and preserving integrity. One observes that engines treated with this oil respond with steadiness and endurance, as if guided by a rational principle, minimizing wear and extending life in a manner that reflects the pursuit of the Good. I grant it five stars, for it exemplifies a balance between strength and refinement, a practical embodiment of foresight, wisdom, and care—ensuring that motion, that vital energy, continues undisturbed, much as a well-ordered soul achieves its fullest expression through the contemplation of virtue.

Extraordinary resource
Format: Paperback, Format: Paperback
I am a Cultural History Interpreter in SC. Working at a plantation historic site to bring suppressed history to light is challenging. Prof Sinha's book gives us easily accessible documentation to counter the "Lost Cause" devotees who appear on the site almost daily. Her writing style is clear and lucid, a trait for which I am extremely grateful. The site is including this volume in our staff library. For those just entering the field of Public History, it is indispensable. For the rest of it is a very valuable resource. Highly recommended!
