The Jamo D 600 is a THX Ultra 2 speaker system with a difference. Instead of the usual wardrobe-sized floorstanders you’d expect from a THX-badged system, Jamo has fashioned a set of five smaller wall-mountable speakers. They’ll still eat up a sizeable chunk of your space, but they’re a much more manageable size than, say, the floorstanders of the Crystal Acoustics T2-5.2-UL so should suit those looking for a top-of-the-line cinema room where space is a little more limited.
But this reduction in size doesn’t bring about a compromise in quality. Even with these smaller boxes, the D 600 still has to satisfy THX’s exacting criteria. So even though the satellites’ smaller size means that their bass capabilities are restricted, the system makes up for it by turning over low-frequency duties to two enormous subwoofers.
In this 5.2 setup are three D 600 LCRs for the front and centre channels, a pair of D 600 SUR on rear channel duties and two D 600 SUB powered subwoofers. Build quality is incredible across the board, with cabinets that feel like they’re hewn from granite.
However, elegant isn’t a word we’d use to describe them. The hard-edged boxes and charcoal grey colour scheme could be deemed too industrial for some tastes, although it’s a nice break from gloss black - these really do look and feel like they could've been swiped from a professional cinema.
The D 600 LCRs are 170mm deep cuboids that each contain five front facing drivers. Meanwhile the rear speakers look similar to the D 600 LCR, with the same brutal combination of grey and black. But they’re a completely different type of speaker. As per the teachings of THX, the D 600 SURs are dipoles, which are designed to mask the direction in which effects are coming from, in turn offering a more immersive experience than direct radiating rears. To achieve this, they use a front-firing woofer with the mid-range and high-range drivers facing out at an angle from the two sides of the box.
At around 58cm high and 50cm deep, the subwoofers are enormous. Fitting just one of these in your room could be quite a task, let alone two, but if you want a thunderously powerful home cinema experience in the way THX intended then you’d better start rearranging the furniture.
Their closed enclosures are styled to match the satellites in their charcoal grey finish. The 15in driver is hidden behind a removable black grille, and on top is a panel of touch-sensitive controls that allow you to activate the DSP settings and tweak volume, crossover and phase controls using the /- keys.
This control panel sounds funky, but feels oddly old-fashioned with its green lights and cumbersome operation. In fact the subs as a whole are a little underwhelming - they're big, ugly and at 32kg a piece, very heavy. Lucky they're meant to be hidden in corners then.
