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 A7 is a 2-way design whereas the Kendall is a 3-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.

A7 features a 0.87" Tweeter and 1 x 7.09" Woofer with a Crossover frequency at 3,700 Hz. 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
A7 has a frequency range of 32-25k 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 A7's min frequency of 32Hz.
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
A7 and Kendall have the same Impedance of 8 ohms but where they differ is the sensitivity levels. A7 sensitivity is rated at 88 dB and the Kendall's is at 96 dB. This 8 dB difference makes the KLH Kendall a more sensitive speaker compared to Spendor A7, hence will play louder with the same amount of watts.

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. A7 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 Spendor A7's and KLH Kendall's external dimensions. Spendor A7 has external dimensions of 934.0 x 177.8 x 304.8mm (36.77 x 7 x 12inch) 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 clearly the larger of the two speakers. Its body is 34.2mm wider, 87mm taller and 75.2mm deeper than Spendor A7.
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.
KLH Kendall needs about 49% more floor or shelf area. KLH Kendall is 75mm deeper, so it stands that much further out from the wall. KLH Kendall is 87mm 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 Spendor A7 is approximately 541.9cm2 / 84.0inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The A7 requires 33% less surface area than the Kendall which gives it a small advantage 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 Spendor A7 weighs 18.00kg / 39.6lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the Kendall 23% heavier than the A7.
Here is a comparison of how A7 and Kendall's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Spendor A7 costs roughly 4.2x 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 32Hz. A subwoofer would even that out. |
| Amplifier needs | B | KLH Kendall is more sensitive (96dB vs 88dB), so it goes louder on the same amplifier. |
| Size | depends | Spendor A7 is easier to place; KLH Kendall is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | KLH Kendall: bi-amping. |
| Price | B | KLH Kendall is cheaper - $1,500 against $6,300, about 76% less; arguably a different class. |
A Spendor A7 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 Spendor A7 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 32Hz anyway, so judge these on the other rows instead. In a large or open-plan room, KLH Kendall has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Spendor A7 is the easier speaker to get right.
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.
