PSB Imagine T2 Tower Speakers


Design of the PSB Imagine T2 Tower Speakers

The Imagine series in general follows a new path in design from say, the substantial reference Synchrony Series. Unlike the conventional looking Synchrony speaker of square edges and flat fronts, the T2's enclosure is curved reducing internal standing waves. The front, sides and top are raked front to back making the T2 appear svelte and lean, surely aiding in room aesthetics.

However to say that the shape is functional and inertly solid is to detract from the amazingly slim and elegant styling.

But looks are deceiving, the Imagine T2 just "feels" like a smaller speaker than it really is. It stands just over 40 inches and quite deep at almost 14. The narrow face at about 6 inches widens in the middle to about 7.5 inches before tapering on the rear.

The enclosure is solid and hefty weighing 42 pounds. To achieve the design, the front is shaped from 2" thick mdf while the sides consist of 7 thin layers of mdf glued together and formed into shape. Each driver, save the tweeter, is slightly recessed and has a rubber shroud.

The finish is stunning, so much so it looks fake; a flaw would have been nice to see that it was real veneer. My review pair arrived in dark cherry while black ash, walnut and traditional gloss black and white are also available.

The obvious genesis to the T2 format and design is the predecessor Imagine T. The Imagine T has 3 drivers in a 2 ½-way design using a pair of 5 1/4" woofer drivers along with a 1" titanium dome tweeter found throughout the Imagine line.

The T2 steps it up, significantly with a "transitional" 5-way design which means there is a blending of crossovers. Imagine T2 tower speaker is essentially 4 enclosures plus dome tweeter stacked on themselves as each of the 4 cone drivers is partitioned horizontally.

Three 5 ¼" drivers are also ported individually on the rear but PSB provides port plugs for bass control in certain rooms.

From the cross-sectional image you can see the upper woofer is crossed-over to the 4" mid-range driver. Placed at ear level (if you're seated) is the 1" tweeter. Both the woofer and mid-range drivers are clay/ceramic filled, reinforced polypropylene cones with a rubber surround, while the tweeter has a titanium dome and a Ferrofluid (friction-reducing) Neodymium Magnet.

Besides the 3 flared ports on the rear, conveniently located near the bottom are the gold plated, 5-way bi-wireable/bi-ampable binding posts. The speaker sits on 4 molded feet and is supplied with adjustable carpet spikes.

Although I couldn't find the time to bench test the T2, the manufacturers spec purports an on-axis frequency response between 34-23,000kHz and an in-room sensitivity of about 90 dB. A 30 degree off-axis response drops the upper range to about 10,000 kHz. I did run some test tones ranging from 25 Hz-25kHz and found in my room no dips but a bit of a bump at around 300 Hz and also around 1kHz of about 3dB. Roll-off on the high end seemed to begin around 12.5kHz and sharply at about 15kHz. This was all unscientific with a microphone and a USB interface and an RTA on my laptop.
