VR-1100

Pair This compact and ultra-slim tower has an almost unbelievable punch for it’s size. A side firing, high power 8" glass resin woofer is transmission line loaded for deep and powerful bass response. Midrange frequencies are clearly reproduced by a 5.5" glass fiber diaphragm for high transparency, while treble is ultra smooth due to 1" synthetic dome with Ferrofluid cooling. Huge soundstage imaging and dipolar semi-omnidirectional response is generated by the 1" rear-firing ambience driver with Spatial Dimension circuitry. The highest quality crossover parts are utilized, including polypropylene and mylar capacitors on the tweeter circuit, along with large gage air cored inductors. The woofer inductor can handle 500 watts before saturation, and all wiring is solid core 5-9's high purity copper with foamed Teflon dialectric shielding. Single set of five way binding posts are solid brass with gold plating, and can not be stripped or broken. Can be ordered with CE binding posts. Solid hardwood endcaps are available in dark red cherry, natural cherry, natural oak, and black laquer oak. Grill colors are black, off-white, or desert sand. Power rating: 10 to 200 watts. Frequency range: 32Hz- 25kHz. Impedance: 8 ohms nominal. Sensitivity: 90dB. Weight: 65 lbs. Size: 7"w, 16"d, 40"h.

Lowther’s DX-65 driver in the Teresonic Magus XR Review

A new driver from Lowther is real news. A new five inch driver is even rarer news, so it was with great anticipation that I waited on this pair of speakers to arrive.

Aune Mini Headphone DAC User Review

The unit arrived from China well packed and everything seem to be in place. No external abuse by the carriers. The only problem was the power supply it came with. The box came with a cheap step-down converter.
