LS-6

PureArtFi LS-6 design philosophies 

The LS-6 project melds state-of-the-art hi-fi with the speaker as fine furniture objects. Using hardwoods and handmade craftmanship yielding beautiful objects for use in discerning homes where music is an important part of one’s lifestyle.

Aesthetics

Clean and simple the exterior design features the rectilinear design elements that predominate in most homes’ interior designs. Hiding the speakers’ technical complexity inside the enclosures allows the cabinetmaker’s art to come to the forefront using selected solid hardwoods and veneers.  Master cabinet building beginning with CNC machining then onto traditional bench craft and hand tools fabricate the enclosures. Multiple layers of hand rubbed oil finishing brings out the wood’s beauty as no production line sprayed finish can. The vital ingredient being the decades of experience in bespoke cabinetmaking and finishing that are brought to bear.

Woofer and Enclosure

It is very common in HiFi to claim a ‘breakthrough’ for incremental improvements. The LS-6’s woofers  are sourced from Purifi featuring their USHINDI - Ultra Low Distortion Transducer Technology, real major improvements to the state of the art based on rethinking of first principles. The resulting lowering of measured distortion is clearly audible as a clarity, depth, and dynamic openness one typically only hears from the best large format drivers in very large enclosures. Purifi’s 6.5 inch woofer and dual passive radiators provide the LS-6’s midrange and bass system foundation. Every prototype using this state-of-the-art redefining driver set sounded great. As development progressed it became apparent the extremely linear and powerful motor system pumps both a tremendous amount of music into the room while also dumping higher than usual reaction forces into the enclosure. Each enclosure upgrade to stronger more inert techniques yielded audible improvements. Ultimately 1+ inch thick panels, constrained layer damping, and limp mass damping were brought to bear in the enclosure’s construction. The resulting system sets the music free from the distortion added by typical less overbuilt woofer enclosure systems. 

Tweeter

Finding a tweeter system to reproduce music’s’ treble tones that is as low in distortion and dynamic as the Purifi woofers proved a challenge. The solution is a horn waveguide loaded ribbon planar type. Hidden inside the enclosure a large back chamber damps and absorbs the driver’s rear wave opening up treble dynamics and ‘air’.

Crossover

A carefully refined crossover circuit seamlessly blends the drivers together. Every component in the crossover network is audio grade. Inductors all feature air core construction and generous wire gauges. All capacitors are polypropylene types designed specifically for HiFi use. Internal wire and connectors are specified to assure no weak links exist in the crossover system. The physical realization of the circuit is point to point wired with the tweeter and woofer sections separately housed within the enclosure reducing cross talk. Each section is enclosed in a damped box that serves double duty breaking up the enclosure’s internal volume standing waves further lowering resonance effects. 

Stands

Speaker stands designed specifically as part of the LS-6 system complete the aesthetic design ensuring pride of place once installed. The stands also feature fasteners into the speaker improving stability, de-coupling dampers improving sound, and internal wiring paths allowing a visually clean connection to the amplifier. Should you prefer to order just the speakers the connectors can be moved to the LS-6 allowing use of your stand or shelf.

Ordering & Cost

Ordering the LS-6 begins with your desires, as a bespoke product we will discuss topics like wood options which leads to resulting finish options. From those choices a delivery time can be estimated. Once the build parameters are set a down payment starts the build. From time to time there are available built units as an option should they fit your needs. 

Pricing varies according to the clients’ choices in the hardwoods and finishes. As a typical  example in American hardwoods like the walnut baffle plus shop sawn 1/8” spalted hackberry veneer speaker and stand displayed at recent shows and YouTube coverage cost is $10,750/pair for the speaker and $3,875/pair for the stands. Exotic tropical hardwoods, specialty staining, and burled veneers quoted on a case-by-case basis.
