In this review, we will be comparing Super Denton and Sandwich 150, two Passive Bookshelf speakers from Wharfedale and Leak. Let's have a brief look at the main features
of Wharfedale Super Denton and Leak Sandwich 150 first before getting into our more
detailed comparison.
What size room are the Wharfedale Super Denton and Leak Sandwich 150 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 Wharfedale Super Denton and Leak Sandwich 150 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 Super Denton is a 3-way design whereas the Sandwich 150 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.

Super Denton features a 1" woven textile Soft-Dome Tweeter , a 2" Midrange and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 940Hz and 4.6kHz. On the other hand, the Sandwich 150 features a 1.2" Coated Textile Dome Tweeter and 1 x 6.5" Aluminium-Foamcore Sandwich cone Woofer with a Crossover frequency at 2400Hz.
Frequency Response
Super Denton has a frequency range of 52-20k Hz whereas Sandwich 150 has a frequency range of 44Hz-26kHz. With a minimum frequency of 44Hz, the Sandwich 150 can go significantly deeper on the low side and provide stronger bass compared to the Super Denton's min frequency of 52Hz.
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
Super Denton is a 6 ohms speaker compared to the Sandwich 150 which has a nominal impedance of 4 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 150 can provide this impedance level.
These two speakers also have different sensitivity levels. Super Denton sensitivity is rated at 87 dB and the Sandwich 150's is rated at 86.5 dB.
Sensitivity

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.
Super Denton can handle a max power of 150 watts RMS from the amp the whereas Super Denton has a max power handling value of 120 watts RMS , 30 watts less than the Sandwich 150.
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
Super Denton features Binding post posts which make bi-amping or bi-wiring possible. Sandwich 150 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Super Denton and Sandwich 150 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 Wharfedale Super Denton's and Leak Sandwich 150's external dimensions. Wharfedale Super Denton has external dimensions of 360 x 246 x 295mm ( 14-1/8inch x 9-11/16inch x 11-5/8inch ) whereas Leak Sandwich 150 has external dimensions of 415 x 250 x 290 mm ( 16.3 x 9.9 x 11.4 inch) .
Wharfedale Super Denton is 4mm narrower and 55mm shorter than Leak Sandwich 150 but it is also 5mm 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 Wharfedale Super Denton is approximately 725.7cm2 / 112.5inch2 and base area of the Leak Sandwich 150 is approximately 725.0cm2 / 112.4inch2. The Super Denton requires 0% more surface area than the Sandwich 150 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 Wharfedale Super Denton weighs 9.20kg / 20.2lbs and the Leak Sandwich 150 weighs 12.30kg / 27.1lbs. This makes the Sandwich 150 34% heavier than the Super Denton.
Here is a comparison of how Super Denton and Sandwich 150's weights compare with the average, max and min weights in Passive Bookshelf class.
