SX-50 features a 1" Silk Dome Tweeter and 1 x 5.25" Treated paper Woofer . On the other hand, the Carina BS243.4 features a 1" JET AMT (Ribbon) Tweeter and 1 x 5.25" Aluminum Woofer .
Frequency Response
SX-50 has a frequency range of 50-22k Hz whereas Carina BS243.4 has a frequency range of 46-30k Hz. With a minimum frequency of 46Hz, the Carina BS243.4 can go slightly deeper then the SX-50'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.

High Frequency
Bookshelf Speakers
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
SX-50 is a 8 ohms speaker compared to the Carina BS243.4 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. SX-50 sensitivity is rated at 90 dB and the Carina BS243.4's is rated at 85 dB. This 5 dB difference makes the Cambridge SX-50 a more sensitive speaker compared to ELAC Carina BS243.4, 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.
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
Carina BS243.4 features Post posts which make bi-amping or bi-wiring possible. SX-50 has a 5-way post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
SX-50 has a rear firing port whereas Carina BS243.4 has a bottom firing ports. ELAC Carina BS243.4's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Cambridge SX-50 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 Cambridge SX-50's and ELAC Carina BS243.4's external dimensions. Cambridge SX-50 has external dimensions of 225.0 x 161.0 x 240.0mm ( 8.8 x 6.3 x 9.4inch) whereas ELAC Carina BS243.4 has external dimensions of 321.0 x 205.0 x 247.0mm ( 12-5/8 x 8-1/16 x 9-11/16inch) .
ELAC Carina BS243.4 is clearly the larger of the two speakers. Its body is 44mm wider, 96mm taller and 7mm deeper than Cambridge SX-50.
Below you can see the front view size comparison of Cambridge SX-50 and ELAC Carina BS243.4 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 Cambridge SX-50 is approximately 386.4cm2 / 59.9inch2 and base area of the ELAC Carina BS243.4 is approximately 506.4cm2 / 78.5inch2. The SX-50 requires 24% less surface area than the Carina BS243.4 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
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 Cambridge SX-50 weighs 3.00kg / 6.6lbs and the ELAC Carina BS243.4 weighs 6.70kg / 14.7lbs. This makes the Carina BS243.4 123% heavier than the SX-50.
