In this review, we will be comparing two different type of speakers . Leak Sandwich 250 is a Bookshelf speaker whereas the Heresy IV is a Floor-standing speaker.
Let's have a brief look at the main features
of Leak Sandwich 250 and Klipsch Heresy IV first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the Leak Sandwich 250 and Klipsch Heresy IV compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Sandwich 250 features a 1.2" Coated Textile Dome Tweeter , a 4.25" Midrange and 1 x 11" Aluminium-Foamcore Sandwich cone Woofer with a Crossover frequency at 470Hz and 3100Hz. On the other hand, the Heresy IV features a 1" titanium-diaphragm compression horn-loaded Tweeter , a 1.75" Midrange and 1 x 12" Fiber-composite Woofer .
Frequency Response
Sandwich 250 has a frequency range of 42Hz-26kHz whereas Heresy IV has a frequency range of 48-20k Hz. With a minimum frequency of 42Hz, the Sandwich 250 can go significantly deeper on the low side and provide stronger bass compared to the Heresy IV's min frequency of 48Hz.
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

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
Sandwich 250 is a 4 ohms speaker compared to the Heresy IV which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Sandwich 250 can provide this impedance level.
These two speakers also have different sensitivity levels. Sandwich 250 sensitivity is rated at 88.5 dB and the Heresy IV's is rated at 99 dB. This 10 dB difference makes the Klipsch Heresy IV a more sensitive speaker compared to Leak Sandwich 250, 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.
Sandwich 250 can handle a max power of 250 watts RMS from the amp the whereas Heresy IV has a max power handling value of 100 watts RMS, 150 watts less than the Sandwich 250.
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
Heresy IV features 5-Way post posts which make bi-amping or bi-wiring possible. Sandwich 250 has a Binding post which doesn't feature bi-amping/bi-wiring.
