A set of pre-production twotwo.6s were sent to me for evaluation and, to differentiate, the 6's have a 6.5-inch LF driver (instead of the .5's 5.5-inch), a larger cabinet (H 406 X W 194 X D 364mm), a wider useable frequency range (40Hz to 25kHz), and a longer ATL. ATL is PMC's Advanced Transmission Line™--an internal labyrinth within the cabinet to load the bass driver to extend the low frequency response of this compact monitor.

Both the 5's and 6's use the same 27-mm soft-dome HF driver, the same pair of Class-D power amps--150-watt LF and 50-watt HF, and both accept either balanced or unbalanced analog audio input by way of the rear panel XLR and RCA jacks.

Both models have a rear panel AES3 XLR connector for 32kHz to 192kHz digital audio input and use their own onboard DSP for automatic sample rate conversion of all incoming digital audio to 24-bit/96kHz, internal A-D-D-A, user-equalization, crossover options and driver protection. With digital audio operation, two RJ45 connectors on the rear panel convey volume data and digital audio over standard CAT-5 cables to any number of PMC monitors 'daisy chained' together with the first monitor in the acting as master. There is also an optional PMC Remote Control unit available.

twotwo Series monitors are sold in "handed" pairs and offer the same wide dispersion equally well in either landscape or portrait orientation. If you set them up portrait (vertically), the odd serial-numbered speakers are designated for the left channel and even numbered are designed for the right channel.

To maintain tonal and stereo imaging, PMC recommends the HF driver (which is offset from the centerline of the woofer) to be on the inside edge not on the outside (as you might expect). If you want to set them up landscape such as on top of a meter bridge of a mixing console--just reverse the pair so that the lighted "PMC" logo/overload indicator reads right side up. The manual says that the "acoustic axis is midway between the HF and LF drivers and should be level with the listener's ears."

So far in my small mixing alcove (9.5-feet wide), I went with a portrait set up with the two monitors 42-inches apart (center-to-center) on Sound Anchor floor stands so that the bottom edges of the speakers are 36-inches from the floor just "peeking" over the left and right edges of my 30-inch high DAW desk--also 42-inches wide.

Because of my limited space, the speakers are slightly too close to one another so I chose to have the HF drivers on the outside for hearing additional stereo width. The monitors are toed inward to 25-degrees and I have the LF shelf EQ (750Hz for the .6 monitors) set to +2dB, roll-off slope off and HF shelf set flat. I don't use a sub woofer.

In the short time I've had them, I'm very impressed but still experimenting with their setup in my small room! The built-in DSP works well to shape the monitors' frequency balance to sound their best considering my small room's inherent room mode issues along with my own monitoring preferences. They are an "honest" pair of monitors that make me work harder at perfecting the sound of my mixes. I like their look and styling; their deep cabinets and narrow width give them a diminutive look but sonically, they are far from unnoticed and sound huge! The PMC twotwo.6s are big winners here at my Tones 4 $ Studios.
