What size room are the Triangle Signature Alpha and PSB Synchrony T600 speakers good for?

The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:

Listening Environment* Triangle Signature Alpha PSB Synchrony T600
Near-field Are you nuts? Bad
Small Room Poor Poor
Mid-size Room Average Average
Large Room Good Good
Very Large Room Good Average

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the Triangle Signature Alpha and PSB Synchrony T600 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Driver Setup 3-way 3-way
Tweeter 1-inch 1-inch
Midrange 1 x 6.5-inch 1 x 5.25-inch
Woofer 3 x 6.5-inch 3 x 6.5-inch

Alpha features a 1" Titanium dome Horn-Loaded Tweeter , a 6.5" Midrange and 3 x 6.5" Double ferrite fibreglass Woofer with a Crossover frequency at 290Hz and 2600Hz. On the other hand, the Synchrony T600 features a 1" titanium with ferrofluid cooling and neodymium magnet Dome Tweeter , a 5.25" Midrange and 3 x 6.5" Carbon fiber Woofer with a Crossover frequency at 450Hz and 1800Hz.

Frequency Response

Alpha has a frequency range of 32-22k Hz whereas Synchrony T600 has a frequency range of 24-23k Hz. With a minimum frequency of 24Hz, the Synchrony T600 can go significantly deeper on the low side and provide stronger bass compared to the Alpha's min frequency of 32Hz.

Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Impedance and Sensitivity

Alpha is a 8 ohms speaker compared to the Synchrony T600 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Synchrony T600 can provide this impedance level.

These two speakers also have different sensitivity levels. Alpha sensitivity is rated at 92 dB and the Synchrony T600's is rated at 89 dB. This 3 dB difference makes the Triangle Signature Alpha a more sensitive speaker compared to PSB Synchrony T600, hence will play louder with the same amount of watts.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

Alpha can handle a max power of 300 watts RMS from the amp the whereas Alpha has a max power handling value of 140 watts RMS , 160 watts less than the Synchrony T600.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

Synchrony T600 features Binding post posts which make bi-amping or bi-wiring possible. Alpha has a Binding post which doesn't feature bi-amping/bi-wiring.

PSB Synchrony T600Binding post Terminals
PSB Synchrony T600's Binding post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position

Alpha has a front firing port whereas Synchrony T600 has a rear firing ports. Triangle Signature Alpha's front-firing port gives more flexibility in placement in regards to proximity to walls compared to PSB Synchrony T600 with its rear-firing port.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Triangle Signature Alpha's and PSB Synchrony T600's external dimensions. Triangle Signature Alpha has external dimensions of 1270.0 x 233.0 x 372.0mm ( 50 x 9-3/16 x 14-5/8inch) whereas PSB Synchrony T600 has external dimensions of 1048.0 x 228.0 x 343.0mm ( 41-1/4 x 9 x 13-1/2inch) .

Triangle Signature Alpha is clearly the larger of the two speakers. Its body is 5mm wider, 222mm taller and 29mm deeper than PSB Synchrony T600.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The base surface area of the Triangle Signature Alpha is approximately 866.8cm2 / 134.4inch2 and base area of the PSB Synchrony T600 is approximately 782.0cm2 / 121.2inch2. The Alpha requires 11% more surface area than the Synchrony T600 which gives it a small disadvantage on placement in tight spaces.

Weight Comparison

The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Triangle Signature Alpha weighs 34.50kg / 75.9lbs and the PSB Synchrony T600 weighs 34.90kg / 76.8lbs. This makes the Synchrony T600 1% heavier than the Alpha.

Here is a comparison of how Alpha and Synchrony T600's weights compare with the average, max and min weights in Passive Floor-standing class.
