High Frequency
Center Channel 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
DALI Spektor Vokal is a 6 ohms speaker compared to the SX-70 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. DALI Spektor Vokal sensitivity is rated at 87 dB and the SX-70's is rated at 85 dB. This 2 dB difference makes the DALI Spektor Vokal a more sensitive speaker compared to Cambridge Audio SX-70, 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.
DALI Spektor Vokal can handle a max power of 120 watts RMS from the amp the whereas SX-70 has a max power handling value of 100 watts RMS, 20 watts less than the DALI Spektor Vokal.
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
DALI Spektor Vokal features 5-Way post type posts and SX-70 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.
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 DALI Spektor Vokal's and Cambridge Audio SX-70's external dimensions. DALI Spektor Vokal has external dimensions of 152.0 x 435.0 x 204.0mm ( 6 x 17.1 x 8inch) whereas Cambridge Audio SX-70 has external dimensions of 139.0 x 362.0 x 248.0mm ( 5-7/16 x 14-1/4 x 9-3/4inch) .
Cambridge Audio SX-70 is 73mm narrower and 13mm shorter than DALI Spektor Vokal but it is also 44mm deeper.
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 DALI Spektor Vokal is approximately 887.4cm2 / 137.5inch2 and base area of the Cambridge Audio SX-70 is approximately 897.8cm2 / 139.2inch2. The DALI Spektor Vokal requires 1% less surface area than the SX-70 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 DALI Spektor Vokal weighs 5.30kg / 11.7lbs and the Cambridge Audio SX-70 weighs 4.00kg / 8.8lbs. This makes the DALI Spektor Vokal 33% heavier than the SX-70.
