Roth Audio OLi 3 - Roth Audio OLi 3
Turning to the OLi C2 centre, the first thing to notice is how disproportionately large it is compared with the other speakers – accommodating it under your TV will be no mean feat. It does however, share the same stunning construction as the fronts, with the combination of wood and gloss black panels providing a perfect aesthetic match. It’s also timbre matched to the other speakers using the same woofers and tweeter as the fronts to ensure a seamless soundstage, except this time the tweeter is placed in between the woofers.
Next up are the OLi1s, which feature a single 4in woofer and 1in tweeter. At 200mm high they won’t be easy to conceal but thankfully the gorgeous lacquer finish of the gently curved top panel will make them a classy addition to your living space. They can handle up to 100W, which isn’t to be sniffed at.
Providing those all-important low-frequency effects is the OLi KH2. This bassy bad boy has a polite, compact size, although its blocky shape is frumpy and the old-school ‘blister’ buttons on the top look a bit naff.
As well as electronic volume control, these buttons let you choose from a range of electronic crossover presets, which is a nice idea for newcomers to home cinema. These settings are more hit-and-miss than the crossover dial found on most subwoofers, but they simplify the process of matching the sub to the rest of the speakers.
There are modes for small, medium and large ‘tower’ speakers – the first reinforces bass in the 50Hz-140Hz range, the second in the 40Hz-100Hz range and the third boosts the 30Hz-80Hz range (we found the lattermost to be the most appropriate for this system). A fourth setting, LFE, allows you to control bass management using your AV receiver.
On the back panel you’ll find a low-level line input, springclips speaker level L/R inputs and switches to flip the phase and select the auto power mode. Inside the sealed enclosure is a front-firing 8in PolyCel active woofer, dual 8in side-firing depth drivers and a 125W amplifier. Its frequency range reaches from 35Hz up to 150kHz.
