In this review, we will be comparing Sonetto CII and A135C, two Passive Center Channel speakers from Sonus Faber and JBL. Let's have a brief look at the main features
of Sonus Sonetto Center II and JBL Stage A135C first before getting into our more
detailed comparison.
What size room are the Sonus Sonetto Center II and JBL Stage A135C 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:
In the following sections, we will get into more detail in order to better understand how the Sonus Sonetto Center II and JBL Stage A135C compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Sonetto CII is a 3-way design whereas the A135C is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Sonetto CII features a 1.15" high definition DAD Dome Tweeter , a 6" Midrange and 2 x 6" aluminum cone Woofer with a Crossover frequency at 1.650 Hz. On the other hand, the A135C features a 1" aluminum dome with HDI (High Definition Imaging) waveguide technology Tweeter and 6 x 3" polycellulose Woofer .
Frequency Response
Sonetto CII has a frequency range of 42-25k Hz whereas A135C has a frequency range of 75-40k Hz. With a minimum frequency of 42Hz, the Sonetto CII can go significantly deeper on the low side and provide stronger bass compared to the A135C's min frequency of 75Hz.
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 Center Channel 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
Sonetto CII is a 4 ohms speaker compared to the A135C which has a nominal impedance of 6 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 Sonetto CII can provide this impedance level.
These two speakers also have different sensitivity levels. Sonetto CII sensitivity is rated at 91 dB and the A135C's is rated at 90 dB. This 1 dB difference makes the Sonus Sonetto Center II a more sensitive speaker compared to JBL Stage A135C, hence will play louder with the same amount of watts.
Sensitivity
Center Channel Speakers
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.
Sonetto CII can handle a max power of 300 watts RMS from the amp the whereas A135C has a max power handling value of 150 watts RMS, 150 watts less than the Sonetto CII.
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
Sonetto CII features Binding post posts which make bi-amping or bi-wiring possible. A135C has a 5-way post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Sonetto CII has a rear firing port whereas A135C has a side firing ports.
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 Sonus Sonetto Center II's and JBL Stage A135C's external dimensions. Sonus Sonetto Center II has external dimensions of 289.0 x 743.0 x 409.0mm ( 12 x 30 x 16inch) whereas JBL Stage A135C has external dimensions of 105.0 x 747.0 x 186.0mm ( 4-1/8 x 29-3/8 x 7-5/16inch) .
JBL Stage A135C is 184mm shorter and 223mm less deeper than Sonus Sonetto Center II but it is also 4mm wider.
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 Sonus Sonetto Center II is approximately 3038.9cm2 / 471.0inch2 and base area of the JBL Stage A135C is approximately 1389.4cm2 / 215.4inch2. The Sonetto CII requires 119% more surface area than the A135C 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 Sonus Sonetto Center II weighs 16.20kg / 35.6lbs and the JBL Stage A135C weighs 7.46kg / 16.4lbs. This makes the Sonetto CII 117% heavier than the A135C.
Here is a comparison of how Sonetto CII and A135C's weights compare with the average, max and min weights in Passive Center Channel class.
