DALI Spektor 2 features a 1" Soft-Dome Tweeter and 1 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2600Hz. On the other hand, the TSi100 features a 1" Dome Tweeter and 1 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
DALI Spektor 2 has a frequency range of 54-26k Hz whereas TSi100 has a frequency range of 61-24k Hz. With a minimum frequency of 54Hz, the DALI Spektor 2 can go significantly deeper on the low side and provide stronger bass compared to the TSi100's min frequency of 61Hz.
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
DALI Spektor 2 is a 6 ohms speaker compared to the TSi100 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. DALI Spektor 2 sensitivity is rated at 84.5 dB and the TSi100's is rated at 89 dB. This 4 dB difference makes the Polk TSi100 a more sensitive speaker compared to DALI Spektor 2, 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
DALI Spektor 2 features Pair of 5-way Binding Posts - Gold-Plated type posts and TSi100 has a Pair of 5-way Binding Posts - Gold-Plated type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both DALI Spektor 2 and TSi100 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 DALI Spektor 2's and Polk TSi100's external dimensions. DALI Spektor 2 has external dimensions of 292.0 x 170.0 x 228.0mm ( 11.5 x 6.7 x 9.4inch) whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) .
DALI Spektor 2 is 7.8mm narrower and 31mm less deeper than Polk TSi100 but it is also 12.6mm taller.
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 2 is approximately 387.6cm2 / 60.1inch2 and base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2. The DALI Spektor 2 requires 16% less surface area than the TSi100 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 2 weighs 4.20kg / 9.2lbs and the Polk TSi100 weighs 4.53kg / 10lbs. This makes the TSi100 8% heavier than the DALI Spektor 2.
Here is a comparison of how DALI Spektor 2 and TSi100's weights compare with the average, max and min weights in Passive Bookshelf class.
