Quatuor 40th features a 1" Magnesium dome Horn-Loaded Tweeter, a 6.5" Midrange and 3 x 6.5" Fibreglass sandwich Woofer with a Crossover frequency at 350Hz and 2500Hz. On the other hand, the Kendall features a 1" anodized aluminum Tweeter, a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer.
Frequency Response
Quatuor 40th has a frequency range of 33-30k Hz whereas Kendall has a frequency range of 25-23k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the Quatuor 40th's min frequency of 33Hz.
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
Quatuor 40th and Kendall have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Quatuor 40th sensitivity is rated at 91 dB and the Kendall's is at 96 dB. This 5 dB difference makes the KLH Kendall a more sensitive speaker compared to Triangle Magellan Quatuor 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.
Quatuor 40th can handle a max power of 260 watts RMS, whereas Kendall has a max power handling value of 250 watts RMS, 10 watts less than the Quatuor 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.

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
Kendall features Binding post posts which make bi-amping or bi-wiring possible. Quatuor 40th has a Binding post which doesn't 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 Triangle Magellan Quatuor 40th's and KLH Kendall's external dimensions. Triangle Magellan Quatuor 40th has external dimensions of 1280.0 x 250.0 x 340.0mm (50-3/8 x 9-13/16 x 13-3/8inch) whereas KLH Kendall has external dimensions of 1021.0 x 212.0 x 380.0mm (40-3/16 x 8-5/16 x 14-15/16inch).
KLH Kendall is 38mm narrower and 259mm shorter than Triangle Magellan Quatuor 40th but it is also 40mm deeper.
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. KLH Kendall is 40mm deeper, so it stands that much further out from the wall. Triangle Magellan Quatuor 40th is 259mm 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 Quatuor 40th is approximately 850.0cm2 / 131.8inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The Quatuor 40th requires 6% more surface area than the Kendall 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 Triangle Magellan Quatuor 40th weighs 47.00kg / 103.4lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the Quatuor 40th 112% heavier than the Kendall.

These sit in different price classes - Triangle Magellan Quatuor 40th costs roughly 14.7x what KLH Kendall does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | KLH Kendall digs deeper - 25Hz against 33Hz. A subwoofer would even that out. |
| Amplifier needs | B | KLH Kendall is more sensitive (96dB vs 91dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (260W vs 250W). |
| Size | depends | KLH Kendall is easier to place; Triangle Magellan Quatuor 40th is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | KLH Kendall: bi-amping. Triangle Magellan Quatuor 40th sits in a wider range (4 models), so a matched surround system is easier later. |
| Price | B | KLH Kendall is cheaper - $1,500 against $22,000, about 93% less; arguably a different class. |
A Triangle Magellan Quatuor 40th B KLH Kendall
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
KLH Kendall is the easier recommendation: it leads on most of the measured areas and costs less. Take Triangle Magellan Quatuor 40th if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 33Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, KLH Kendall is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
