Finally, there’s a subwoofer 
driver that just might be stronger 

than your biggest amplifier. With 

an almost inconceivable power 
handling capacity of 2400 watts 
program, the Lo Max has more 
real world power handling than any 
other commercially available sound 

reinforcement loudspeaker. A no 

compromise design combines this 

power capacity with high efficiency, 

excellent frequency response and 
low distortion for revolutionary 

performance. It even works well in 
compact enclosures.

DESIGN

The Lo Max utilizes the same strong 
Kevlar

®

 composite cone and dustcap 

used in the Low Rider

®

 series. 

The cone is strong and tough, and 
uses an innovative asymmetrical-M 
surround for superior excursion and 

motion control.

High quality gold on brass spring 
plunger terminals accepting large 
gauge wire are attached to large 
diameter, high-current tinsel leads 
with silver solder to withstand high 
currents, high temperatures and long 

excursion. The tinsel termination is 

coated with an elastomer material to 

improve flex life.

The massive 4” diameter voice coil 
uses polyamide insulated copper 

ribbon wire, edge wound and 
bonded onto an incredibly durable 
and heat resistant polyamide 

composite former. With a winding 
length of 1.150”, the long coil 

has much more surface area to 
dissipate heat, and its increased 
length drives the cone to a far 

higher excursion. The coil is over 

coated with a tough thermoset 

epoxy for added durability, 
abrasion resistance and heat 

dissipation.

The coil wires are solderless 
diffusion welded to high 
conductivity OFHC copper ribbon
