What size room are the Q Acoustics Concept 50 and Q Acoustics Concept 500 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* Q Acoustics Concept 50 Q Acoustics Concept 500
Near-field Bad Bad
Small Room Poor Poor
Mid-size Room Average Average
Large Room Good Good
Very Large Room Average 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 Q Acoustics Concept 50 and Q Acoustics Concept 500 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers

Both Concept 50 and Concept 500 are 2-way speakers.

Driver Setup 2-way 2-way
Tweeter 1-inch 1.1-inch
Midrange - -
Woofer 2 x 5-inch 2 x 6.5-inch

Concept 50 features a 1" Dome Tweeter and 2 x 5" Paper composite Woofer with a Crossover frequency at 2100Hz. On the other hand, the Concept 500 features a 1.1" Dome Tweeter and 2 x 6.5" Paper composite Woofer with a Crossover frequency at 2500Hz.

Frequency Response

Concept 50 has a frequency range of 42-30k Hz whereas Concept 500 has a frequency range of 41-30k Hz. With a minimum frequency of 41Hz, the Concept 500 can go slightly deeper then the Concept 50's min frequency of 42Hz.

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.

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.

Concept 50 can handle a max power of 200 watts RMS from the amp the whereas Concept 50 has a max power handling value of 150 watts RMS , 50 watts less than the Concept 500.

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

Concept 50 features Binding post type posts and Concept 500 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position

Both Concept 50 and Concept 500 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 Q Acoustics Concept 50's and Q Acoustics Concept 500's external dimensions. Q Acoustics Concept 50 has external dimensions of 1025.0 x 418.0 x 319.0mm ( 40-3/8 x 16-7/16 x 12-9/16inch) whereas Q Acoustics Concept 500 has external dimensions of 1175.0 x 400.0 x 375.0mm ( 46-1/4 x 15-3/4 x 14-3/4inch) .

Q Acoustics Concept 50 is 150mm shorter and 56mm less deeper than Q Acoustics Concept 500 but it is also 18mm 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 Q Acoustics Concept 50 is approximately 1333.4cm2 / 206.7inch2 and base area of the Q Acoustics Concept 500 is approximately 1500.0cm2 / 232.5inch2. The Concept 50 requires 11% less surface area than the Concept 500 which gives it a small advantage 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 Q Acoustics Concept 50 weighs 22.90kg / 50.4lbs and the Q Acoustics Concept 500 weighs 42.00kg / 92.4lbs. This makes the Concept 500 83% heavier than the Concept 50.

Here is a comparison of how Concept 50 and Concept 500's weights compare with the average, max and min weights in Passive Floor-standing class.
