Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Perfect Bass Kit (PBK): Even when a MartinLogan subwoofer is ideally
placed, the dynamics of each listening environment present a unique challenge
for bass performance. The Perfect Bass Kit (PBK) learns vital information about
your unique space, maximizing the subwoofer's performance. The PBK system
employs your PC, connected via USB to a microphone and your MartinLogan
subwoofer, to identify problem areas in your listening environment. The PBK
processes information from multiple data points and configures the optimal
solution, achieving pinpoint-accurate room response.
Compatibility: The Perfect Bass Kit (PBK) is for use with a
MartinLogan powered subwoofer with a PBK Interface (such as the
Dynamo 1500X, sold separately) to correct the effects of room boundaries on
sound quality. PBK can be used with up to four MartinLogan subwoofers. The
included PBK software installation CD requires a Windows PC running XP, Vista,
or 7; and two free USB (type-A) ports.
Note: If your home theater receiver also has a Room Correction
system, PBK should be set up and running before setting up your system's
'EQ', especially if more than one PBK subwoofer will be in use.
PC Software: The PBK included software disc employs your PC's
processor to calculate correction curves for each measurement point,
substantially minimizing the rounding errors of less sophisticated
"calculators", like those used in standard room equalization systems. PBK uses
proprietary processing to compute the subwoofer's in-room frequency response and
then computes a target frequency response for the subwoofer to yield optimal
Note: Check MartingLogan's
website for the latest PBK software download.
Multiple-Measurement Points: Current room equalization systems are
capable of taking a single measurement at the primary listening position. PBK
utilizes multiple measurement points, at least five (up to ten) individual data
positions, allowing PBK to learn the individual characteristics of your room.
Mic & Stand: The Perfect Bass Kit (PBK) includes a microphone and
telescoping stand. During the measurement process, the microphone must be
pointed toward the ceiling and be positioned at ear level when you are seated.
USB Cables: The included 12.5' USB cables connect the PBK's microphone
and your compatible MartinLogan subwoofer to your Windows PC.
