Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Klipsch SPL-100 and B&W DB3D have a totally different setup: the Klipsch SPL-100 features 1 x 10-inch drivers whereas the DB3D features 2 x 8-inch drivers.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas DB3D has a frequency range of 10-350Hz. With a minimum frequency of 10Hz, the DB3D can go significantly deeper on the low side and provide stronger bass compared to the SPL-100's min frequency of 27Hz.

Cabinet Type
The Klipsch SPL-100 has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the B&W DB3D have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Klipsch SPL-100's and B&W DB3D's external dimensions. Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm ( 16-7/16 x 14-1/16 x 18-13/16inch) whereas B&W DB3D has external dimensions of ( ) .
