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 Polk RTi A3 and Q Acoustics 3030i compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

RTi A3 features a 1" silk polymer composite Dome Tweeter and 1 x 6.5" Polymer composite Woofer with a Crossover frequency at 2800Hz. On the other hand, the 3030i features a 1" decoupled Tweeter and 1 x 6.5" Coated paper Woofer with a Crossover frequency at 2400Hz.
Frequency Response
RTi A3 has a frequency range of 50-26k Hz whereas 3030i has a frequency range of 46-30k Hz. With a minimum frequency of 46Hz, the 3030i can go slightly deeper then the RTi A3's min frequency of 50Hz.
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 Bookshelf 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
RTi A3 is a 8 ohms speaker compared to the 3030i which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. RTi A3 sensitivity is rated at 89 dB and the 3030i's is rated at 88 dB. This 1 dB difference makes the Polk RTi A3 a more sensitive speaker compared to Q Acoustics 3030i, 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.
RTi A3 can handle a max power of 150 watts RMS from the amp the whereas 3030i has a max power handling value of 75 watts RMS, 75 watts less than the RTi A3.
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
RTi A3 features Pair of Dual 5-way Binding Posts - Gold-Plated posts which make bi-amping or bi-wiring possible. 3030i has a Binding post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
RTi A3 has a back and front firing port whereas 3030i has a rear 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 Polk RTi A3's and Q Acoustics 3030i's external dimensions. Polk RTi A3 has external dimensions of 374.7 x 214.4 x 355.6mm ( 14.7 x 8.4 x 14.0inch) whereas Q Acoustics 3030i has external dimensions of 325.0 x 200.0 x 329.0mm ( 12.7 x 7.8 x 12.9inch) .
Polk RTi A3 is clearly the larger of the two speakers. Its body is 14.4mm wider, 49.7mm taller and 26.6mm deeper than Q Acoustics 3030i.
Below you can see the front view size comparison of Polk RTi A3 and Q Acoustics 3030i in scale.

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 Polk RTi A3 is approximately 762.4cm2 / 118.2inch2 and base area of the Q Acoustics 3030i is approximately 658.0cm2 / 102.0inch2. The RTi A3 requires 16% more surface area than the 3030i which gives it a small disadvantage on placement in tight spaces.
