The single uniK 05+ from ESI is a professional-quality 2-way bi-amped monitor developed for professional audio engineers and producers looking for high-performance sound reproduction. The monitor utilizes a 1.9 x 1.0" low-mass magnetostatic tweeter and a 5" Kevlar curved-cone woofer, which combine to provide a flat frequency response of 49 Hz to 25 kHz with an SPL output of 101 dB (peak 104 dB). The tweeter features an upgraded design with low moving mass for extended frequency, fast transient response, and high sound resolution, while the matching woofer's Kevlar composite cone offers high stiffness, ensuring better piston motion and exceptional low-end sound reproduction. The built-in crossover ensures a proper phase response and safe power limiting for each of the drivers.

Designed for use with balanced and unbalanced signals, the monitor offers a combo XLR-1/4" input connector. The two amplifiers provide 40W to the tweeter and 40W to the woofer. The rear of the enclosure offers a character control knob with a range of smooth to bright, plus a high-frequency control (10 kHz) and low-frequency control (100 Hz). Other features include a dedicated ground lift, standby mode for energy saving, and flexible rubber feet that are discretely height adjustable and help decouple the enclosure, reduce vibrations, and precisely direct the sound to the optimum position. Additionally, the monitor includes a bass port plug, which is inserted into the rear vent port when placing the monitor against a wall or in a corner. The uniK 05+ ships with a power cord.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.
