Teufel has modified its successful System 5 to create the world's first THX Select 2-certified speaker package, which means it's designed to meet the exacting sonic standards laid down by George Lucas and his band of hardcore home cinema crusaders.
The idea behind THX Select 2 is to deliver the best possible sound quality in rooms where the distance from the listening position to the screen is between 10 and 12 feet. To that end, THX Select 2 certified speakers must feature controlled directivity, in order to achieve "a full soundstage with precise imaging for all types of audio content", and that's one of the things Teufel has tweaked to earn this certification.
Another is the inclusion of two subwoofers, which helps the system reach THX's bass requirements (105dB continuous output at 25Hz minimum frequency, at -3 dB). To get that sort of performance from a single sub it would have to be absolutely massive, so instead Teufel has opted for two reasonably-sized bass boxes, which make the system more 'living room-friendly'.
For the front and centre channels, you get three S 500 FCR speakers, an upgraded version of its predecessor, the M 550 FCR. It's the first speaker ever to get the THX Select 2 seal of approval so we're deep in uncharted territory here. Key to their performance is their newly-developed flat diaphragm midrange drivers, which radiate mids from the entire effective surface area and avoid pesky phase shifts that conventional cone drivers can suffer from.
Teufel also reckons that the drivers' rigid sandwich construction ensures a balanced frequency response, while the central placement of the dome tweeter improves sound radiation and lets you hear full-range sound outside of the sweet spot. And because they fit flush into the enclosure, you don't get any detrimental diffraction effects off corners or edges.
Unsurprisingly, the build quality of these front/centre speakers is phenomenal. Weighty, robust and clad in a fetching old school dark wenge finish, they really look the part. The speaker grille is a removable hood that fits over the front without the need for bolts, another measure designed to keep the distortion wolf from the door.
At 16cm deep, they're surprisingly compact compared with Teufel's other high-end speakers, and can be mounted on optional M 4002 P stands or on the wall using the pre-attached brackets on the back. Also on the rear is an alcove housing a pair of sturdy gold-plated binding posts, found on all of the system's speakers.
