Let's have a brief look at the main features
of Leak Sandwich 250 and KLH Model Five first before getting into our more
detailed comparison.

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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Sandwich 250 and Model Five are 3-way speakers.

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 Model Five features a 1" aluminum Hard-Dome Tweeter, a 4" Midrange and 1 x 10" Pulp-Paper Woofer with a Crossover frequency at 380Hz and 2850Hz.
Frequency Response
Sandwich 250 has a frequency range of 42Hz-26kHz whereas Model Five has a frequency range of 42-20k Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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 Model Five which has a nominal impedance of 6 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 Model Five's is rated at 90.5 dB. This 2 dB difference makes the KLH Model Five a more sensitive speaker compared to Leak Sandwich 250, hence will play louder with the same amount of watts.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Sandwich 250 can handle a max power of 250 watts RMS, whereas Model Five has a max power handling value of 200 watts RMS, 50 watts less than the Sandwich 250.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Sandwich 250 features Binding post type posts and Model Five has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Leak Sandwich 250's and KLH Model Five's external dimensions. Leak Sandwich 250 has external dimensions of 655 x 370 x 300 mm (25.8 x 14.6 x 11.8 inch) whereas KLH Model Five has external dimensions of 870.0 x 350.0 x 330.0mm (34-1/4 x 13-3/4 x 13inch).
Leak Sandwich 250 is 215mm shorter and 30mm less deeper than KLH Model Five but it is also 20mm 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 Leak Sandwich 250 is approximately 1110.0cm2 / 172.1inch2 and base area of the KLH Model Five is approximately 1155.0cm2 / 179.0inch2. The Sandwich 250 requires 4% less surface area than the Model Five which gives it a small advantage on placement in tight spaces.
