Von Schweikert Audio VR-4jr Upper Module MKIII

LOOKING TO MOVE THESE!!

Pictures are the actual pair.

I have the original crates for shipping, but am selling locally for LOCAL PICKUP.

Von SCHWEIKERT VR-4JR Mk.III SPECIFICATIONS:

ONLY THE UPPER MODULE HAS BEEN UPGRADED TO MKIII in June 2012. Lower Woofer Module is still amazing, but upper gives greater clarity to upper frequencies. I have the shipping crates if you wanted to ship the lower modules to Albert in CA for upgrading. Lower modules are loaded with lead shot (as designed) and ARE SUPER HEAVY with no reverb!!! Description below is for MKII version; this upgrade is the newer MKIII version. BETTER!!

One rear dust cap is dented but this has NO IMPACT ON THE SOUND!

System Type: Dynamic-driver four-way system using a triple-chambered transmission line and two-piece stacking enclosure system to eliminate resonance and ensure image focus.

Woofer Tuning:The triple-chambered transmission line is a hybrid design composed of three separate chambers coupled to the room by a tuned vent at 25 Hz. The chamber filling now consists of new internal woofer-chamber damping materials. The 3"-wide damped vent tube extends bass response without the "one note bass" problem found in other ported systems. Dynamic range is incredible due to the large amount of low frequency air movement.

Cabinet and Bracing: A one-inch thick front baffle provides exceptional vibration control and image solidity, while one-inch MDF fiberboard interlocking braces provide exceptional rigidity and freedom from boxy colorations. The internal damping consists of thick acoustic felt lining and Dacron stuffing to eliminate cavity resonances. Large carpet spikes are provided.

Size: Midrange/Tweeter (12.5"h x 8"w x 20"d). Woofer (25.25"h x 8"w x 20"d). System (38.5"h x 8"w x 20"d).

Weight:
Woofer module: 52 lbs.
M/T module: 26 lbs.
System: 78 lbs. each (up to 128 lbs. each with lead shot).

Driver Complement:
2 x 6.5" woofers with new laminate material and newly developed ceramic coating,
1 x 6.5" midrange driver,
1 x 1" poly-tri-laminate silk-dome tweeter,
1 x 1" rear firing ambience mid/tweeter with fabric dome and transmission-line loading.
All drivers use our proprietary Advanced Motor System with low distortion design.

Crossover:
Acoustic fourth order, at 200 Hz and 2.2 kHz, optimized for flat off-axis response and phase consistency over a wide Global Axis.
Very high quality parts are used, including film-foil capacitors and custom air-core inductors that can handle up to 1500 watts before saturation, with computer-optimized internal wire.
The VR-4JR Mk.II offers further improvements, changes and refinements in these crossover networks. These have the upgraded crossovers.

Binding Posts: Double sets of five-way rhodium posts enabling bi-wiring. Single wire can be used with optional Data Link connector (see pictures below).

Ambience Driver:
1" treated fabric dome with Wave Guide and transmission-line rear wave loading.
Ambience circuit uses Dimensional Control (effects level) to compensate for room acoustics and soundstage depth.
Provides a Global Axis polar response pattern to simulate live musical reproduction.

Frequency Response: 23-20 kHz, +/- 2 dB, 20 Hz-25 kHz -6 dB, (+/- 1dB at midband).

Impedance: 6 ohms avg. (4 ohms 20 Hz-150 Hz; 8 ohms 150 Hz-20 kHz).

Recommended Power: 20 watts up to 300 watts music power.

Sensitivity: 89 dB @ 1w/1m using 2.83 v (91.5 dB in room with boundary reinforcement).

• WHAT’S NEW IN THE VR4JR MARK II VERSION:
Although our VR-4JR speaker system has been awarded the highest accolades by seven international magazines over its past four years in production (unchanged), development of our latest model VR-5SE ($ 25,000 / pair) resulted in numerous technical and engineering advances that provided the opportunity for significant trickle-down enhancements to our lower priced models.

These new refinements and advances in technology are now implemented in the newly released VR-4JR Mk2 as well as the new VR4SR also now in the Mark II stage. Over the past years, production, materials, fuel, shipping and assembly costs have all dramatically risen. In response to these conditions we have sought to offset higher costs by providing significant improvements in our products. The new VR4JR MK II is a significant leap forward in performance, smoothness, articulation and transparency over its predecessor while still offering enormous value compared to any other speaker in its price class.

Improvements and changes in the VR4JR Mk II:
1. Tighter bass with higher clarity, achieved with a new woofer featuring significantly improved laminate material; the new coating is a ceramic damping material that replaces the older Bextrene plastic laminate coating; the new coating adds additional stiffness and damping very close to that of our aluminum and magnesium coned woofers supplied with the VR-4SR and VR-5SE models.

2. Improved transparency and clarity in the lower midrange, achieved by new internal woofer-chamber damping materials. In addition, customers are now supplied with 20 pounds of factory-installed sand to dramatically reduce cabinet resonances in the vital lower midrange area.

3. Greater midrange transparency and clarity achieved by improved internal damping of the upper midrange module; this mod includes a high-tech combination of multiple new absorption materials to vastly improve the overall vocal clarity and transparency.

4. Higher power handling and reliability achieved by the addition of a new active circuit protection system against voice coil failure and/or burnout. This variable-state device monitors and holds constant the input voltage to the voice coil and is not a user-replaceable fuse or other part that can wear out or cause sonic degradation. In operation, the circuit is sonically "invisible" but will give owners added protection for their investment.

5. Improvements, changes and refinements in the crossover networks to provide more detail and dynamics especially in the mids and lower ranges. There are also a number of other production refinements made in this model.
