History
What size room are the Triangle Magellan Cello 40th and Triangle Magellan Duetto 40th 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:

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
One of the fundamental differences between these two speakers is that Cello 40th is a 3-way design whereas the Duetto 40th 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.

Cello 40th features a 1" Magnesium dome Horn-Loaded Tweeter, a 6.5" Midrange and 2 x 6.5" Fibreglass sandwich Woofer with a Crossover frequency at 300Hz and 2600Hz. On the other hand, the Duetto 40th features a 1" Magnesium dome Horn-Loaded Tweeter and 1 x 6.5" Natural paper Woofer with a Crossover frequency at 3100Hz.
Frequency Response
Cello 40th has a frequency range of 35-30k Hz whereas Duetto 40th has a frequency range of 40-30k Hz. With a minimum frequency of 35Hz, the Cello 40th can go significantly deeper on the low side and provide stronger bass compared to the Duetto 40th's min frequency of 40Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
Cello 40th and Duetto 40th have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Cello 40th sensitivity is rated at 90 dB and the Duetto 40th's is at 88 dB. This 2 dB difference makes the Triangle Magellan Cello 40th a more sensitive speaker compared to Triangle Magellan Duetto 40th, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
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.
Cello 40th can handle a max power of 200 watts RMS, whereas Duetto 40th has a max power handling value of 80 watts RMS, 120 watts less than the Cello 40th.
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.
Which plays louder on your 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
Cello 40th features Binding post type posts and Duetto 40th has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Cello 40th and Duetto 40th have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
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 Triangle Magellan Cello 40th's and Triangle Magellan Duetto 40th's external dimensions. Triangle Magellan Cello 40th has external dimensions of 1080.0 x 250.0 x 340.0mm (42-1/2 x 9-13/16 x 13-3/8inch) whereas Triangle Magellan Duetto 40th has external dimensions of 460.0 x 250.0 x 350.0mm (18-1/8 x 9-13/16 x 13-3/4inch).
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Near-identical footprints. Triangle Magellan Cello 40th is 620mm 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 Triangle Magellan Cello 40th is approximately 850.0cm2 / 131.8inch2 and base area of the Triangle Magellan Duetto 40th is approximately 875.0cm2 / 135.6inch2. The Cello 40th requires 3% less surface area than the Duetto 40th which gives it a small advantage on placement in tight spaces.
