In this review, we will be comparing Sandwich 250 and Borea BR03, two Passive Bookshelf speakers from Leak and Triangle. Let's have a brief look at the main features
of Leak Sandwich 250 and Triangle Borea BR03 first before getting into our more
detailed comparison.
What size room are the Leak Sandwich 250 and Triangle Borea BR03 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Leak Sandwich 250 and Triangle Borea BR03 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Sandwich 250 is a 3-way design whereas the Borea BR03 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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 Borea BR03 features a 1" silk Tweeter and 1 x 6" fiberglass Woofer with a Crossover frequency at 3600Hz.
Frequency Response
Sandwich 250 has a frequency range of 42Hz-26kHz whereas Borea BR03 has a frequency range of 46 - 22k Hz. With a minimum frequency of 42Hz, the Sandwich 250 can go slightly deeper then the Borea BR03's min frequency of 46Hz.
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.

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 Borea BR03 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 Borea BR03's is rated at 90 dB. This 1 dB difference makes the Triangle Borea BR03 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 Borea BR03 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
Sandwich 250 features Binding post type posts and Borea BR03 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Sandwich 250 has a rear firing port whereas Borea BR03 has a front firing ports. Triangle Borea BR03's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Leak Sandwich 250 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 Leak Sandwich 250's and Triangle Borea BR03'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 Triangle Borea BR03 has external dimensions of 380.0 x 206.0 x 314.0mm ( 14.9 x 8.1 x 12.3inch) .
Triangle Borea BR03 is 164mm narrower and 275mm shorter than Leak Sandwich 250 but it is also 14mm deeper.
Below you can see the front view size comparison of Leak Sandwich 250 and Triangle Borea BR03 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 Leak Sandwich 250 is approximately 1110.0cm2 / 172.1inch2 and base area of the Triangle Borea BR03 is approximately 646.8cm2 / 100.3inch2. The Sandwich 250 requires 72% more surface area than the Borea BR03 which gives it a small disadvantage 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 Leak Sandwich 250 weighs 27.30kg / 60.1lbs and the Triangle Borea BR03 weighs 6.26kg / 13.8lbs. This makes the Sandwich 250 336% heavier than the Borea BR03.
Here is a comparison of how Sandwich 250 and Borea BR03's weights compare with the average, max and min weights in Passive Bookshelf class.
