AVSA review, May 2013

m a y av 2 0 1 3 2 7 control steplessly variable between 0 and 180 degrees, while the low-pass filter can also be seamlessly set between 40 and 200 Hz — or bypassed completely in systems where the low-pass filtering is handled by the receiver or processor. A level control allows further fine-tuning. In cosmetic terms, the 750-THX system is best described as functional: the enclosures are wrapped in unobtrusive black vinyl, and the grilles are clip-on, black anodised metal. Even the gold MK logos are optional. But that said, the assembly quality is top notch, and the overall execution admirable. Having installed the MKs in the AV Magazine listening room, I spent an evening setting up and fine-tuning the system, followed by an extended settling in period of around 100 hours before settling in for a proper listen. I used our NAD T777 reference receiver’s Audyssey set-up procedure for an initial calibration, but then finetuned the receiver’s set-up to reflect the THX-recommended 80 Hz high-pass filter point for the main channels, and a 80 Hz low-pass filter point for the subwoofer. Add some fettling with the individual channel levels, and we were almost raring to go. The sub sounded comfortable and incisive enough in the right front corner of the listening studio, albeit with the phase control turned all the way to the 180 degree mark. I started off with Led Zeppelin’s blockbuster reunion concert, Celebration Day (Atlantic BluRay), and was instantly transported into the very heart of London’s O2 theatre, with the electricity almost tangible and the energy of the band equally enthralling. The recording can suffer from a certain amount of bite, especially when listened to on a more revealing system, and that was certainly the case here, too, but the MK speaker system didn’t allow the slight edge in the upper mids and trebles to detract from the strutting intensity of the music. There is an authenticity to this performance that is often overlooked in the euphoria of its historical significance, but COVER FEATURE LCR-750THX FRONT SPEAKERS Enclosure type............................................................
