Kendall features a 1" anodized aluminum Tweeter, a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer. On the other hand, the Opticon 8 MK2 features a 17 x 45 mm ribbon + 1.125" Soft-dome + ribbon Hybrid Tweeter, a 6.5" Midrange and 2 x 8" Wood Fiber Woofer with a Crossover frequency at 380Hz, 2200Hz and 14,000Hz.
Frequency Response
Kendall has a frequency range of 25-23k Hz whereas Opticon 8 MK2 has a frequency range of 38-30k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the Opticon 8 MK2's min frequency of 38Hz.
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
Kendall is a 8 ohms speaker compared to the Opticon 8 MK2 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 Opticon 8 MK2 can provide this impedance level.
These two speakers also have different sensitivity levels. Kendall sensitivity is rated at 96 dB and the Opticon 8 MK2's is rated at 88 dB. This 8 dB difference makes the KLH Kendall a more sensitive speaker compared to DALI Opticon 8 II, 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.
Opticon 8 MK2 can handle a max power of 300 watts RMS, whereas Kendall has a max power handling value of 250 watts RMS, 50 watts less than the Opticon 8 MK2.
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.

considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Kendall and Opticon 8 MK2 features dual binding post speaker terminals for bi-amping or 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 KLH Kendall's and DALI Opticon 8 II's external dimensions. 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) whereas DALI Opticon 8 II has external dimensions of 1150.0 x 245.0 x 459.0mm (45-1/4 x 9-1/2 x 18-1/16inch).
DALI Opticon 8 II is clearly the larger of the two speakers. Its body is 33mm wider, 129mm taller and 79mm deeper than KLH Kendall.
Below you can see the front view size comparison of KLH Kendall and DALI Opticon 8 II 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 KLH Kendall is approximately 805.6cm2 / 124.9inch2 and base area of the DALI Opticon 8 II is approximately 1124.6cm2 / 174.3inch2. The Kendall requires 28% less surface area than the Opticon 8 MK2 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 KLH Kendall weighs 22.14kg / 48.7lbs and the DALI Opticon 8 II weighs 37.10kg / 81.6lbs. This makes the Opticon 8 MK2 68% heavier than the Kendall.

These sit in different price classes - DALI Opticon 8 II costs roughly 2.8x 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 | A | KLH Kendall digs deeper - 25Hz against 38Hz. |
| Amplifier needs | A | KLH Kendall is more sensitive (96dB vs 88dB), so it goes louder on the same amplifier. |
| Amplifier match | A | KLH Kendall is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (250W vs 300W). |
| Size | depends | KLH Kendall is easier to place; DALI Opticon 8 II is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | KLH Kendall: bi-amping; DALI Opticon 8 II: bi-amping. DALI Opticon 8 II sits in a wider range (6 models), so a matched surround system is easier later. |
| Price | A | KLH Kendall is cheaper - $1,500 against $4,200, about 64% less; arguably a different class. |
A KLH Kendall B DALI Opticon 8 II
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 DALI Opticon 8 II 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 38Hz anyway, so judge these on the other rows instead. In a large or open-plan room, DALI Opticon 8 II has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KLH Kendall 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.
