Cabinets
Nobody else builds lightweight cabinets like this
All LFSys bass cabinets are manufactured on advanced CNC machines by an external specialist and assembled in-house. They are made from the highest quality poplar plywood. The 1 x 12” cabinets, for example, use 15mm material with a total of 11 individual plies.
For maximum rigidity without compromising portability, they employ a 3D bracing structure that interlocks all the cabinet panels and drastically reduces the panel excitations that would otherwise colour the sound, mask detail and soften transients.
All joints and braces are rebated (not butt-jointed), which not only increases the strength of the joints but also dampens the transmission of resonances through the panels. The cabinet walls are lined with damping material to minimise the undesirable effects of internal standing waves.
The bracing and damping configuration for each LFSys cabinet was perfected through extensive research and design iterations to achieve optimal durability and sonic performance.
When only the best is good enough
LFSsys cabinets are equipped with top-quality components from premium makers like Faital Pro, Celestion and B&C. All bass/mid drivers are long-coil types with generous excursion capabilities that have been carefully selected for sound quality and their ability to reproduce the dynamics as well as the nuances of the bass guitar.
To achieve optimum midrange dispersion, LFSys cabs contain the kind of neodymium compression drivers you normally find in high-end PA. These high quality compression drivers and horns are an integral part of the design of LFSys cabs; they're not included as an afterthought to "add a bit of top end". So you won’t find any of the cheap bullet tweeters or phenolic-diaphragm drivers commonly used in bass guitar cabinets.
Selecting the drivers for LFSys cabinets was an extensive process and many were tried and tested both in-house as well as by gigging bass players before settling on the very best components for the task.

“The transient performance and rise time of the system is largely determined by the highest frequency unit in the system (i.e., the treble driver), and has no connection with so called bass unit ‘speed.”

Crossovers
The secret ingredient of great tone
LFSys crossovers are designed using CAD software, repeated measurements and listening tests that benefit from our several decades of experience in this specialist field. Measurements include off-axis response, phase response, impedance, distortion and electrical phase response. The crossovers are also configured to ensure that finished systems present an easy load to the amplifier.
All crossover components are measured for accuracy, and inductors are wound in-house to high tolerances. Every crossover is checked and measured for consistent performance prior to installation.
“As much fun as twiddling with loudspeakers can be, I think that it’s important to realize how much work and expertise goes into a really good design. It's just not that easy to do. It is fairly easy to get "decent" loudspeakers this way, but to get a really good loudspeaker system takes hundreds of hours of design and testing requiring vast knowledge and equipment.” Dr Earl Geddes
