What size room are the DALI Opticon 6 II and DALI Opticon 1 II 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:

Listening Environment* DALI Opticon 6 II DALI Opticon 1 II
Near-field Bad Average
Small Room Poor Good
Mid-size Room Good Average
Large Room Good Poor
Very Large Room Poor Bad

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. 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.)

In the following sections, we will get into more detail in order to better understand how the DALI Opticon 6 II and DALI Opticon 1 II 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 Opticon 6 MK2 is a 3-way design whereas the Opticon 1 MK2 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.

Opticon 6 MK2 features a 17 x 45 mm ribbon + 1.125" Soft-dome + ribbon Hybrid Tweeter and 2 x 6.5" Wood Fiber Woofer with a Crossover frequency at 800Hz, 2200Hz and 14,000Hz. On the other hand, the Opticon 1 MK2 features a 1.125" Soft-Dome Tweeter and 1 x 4.75" Wood Fiber Woofer with a Crossover frequency at 3000Hz.

Frequency Response

Opticon 6 MK2 has a frequency range of 49-30k Hz whereas Opticon 1 MK2 has a frequency range of 62-26k Hz. With a minimum frequency of 49Hz, the Opticon 6 MK2 can go significantly deeper on the low side and provide stronger bass compared to the Opticon 1 MK2's min frequency of 62Hz.

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 Floor-standing 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

Opticon 6 MK2 and Opticon 1 MK2 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Opticon 6 MK2 sensitivity is rated at 88 dB and the Opticon 1 MK2's is at 86 dB. This 2 dB difference makes the DALI Opticon 6 II a more sensitive speaker compared to DALI Opticon 1 II, hence will play louder with the same amount of watts.

One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Opticon 6 MK2 and the Opticon 6 MK2 can provide this impedance level.

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.

Opticon 6 MK2 can handle a max power of 200 watts RMS from the amp the whereas Opticon 1 MK2 has a max power handling value of 100 watts RMS, 100 watts less than the Opticon 6 MK2.

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

Opticon 6 MK2 features Post posts which make bi-amping or bi-wiring possible. Opticon 1 MK2 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position

Both Opticon 6 MK2 and Opticon 1 MK2 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 DALI Opticon 6 II's and DALI Opticon 1 II's external dimensions. DALI Opticon 6 II has external dimensions of 1010.0 x 195.0 x 340.0mm ( 39-3/4 x 7-5/8 x 13-3/8inch) whereas DALI Opticon 1 II has external dimensions of 254.0 x 153.0 x 235.0mm ( 10 x 6 x 9-1/4inch) .

DALI Opticon 6 II is clearly the larger of the two speakers. Its body is 42mm wider, 756mm taller and 105mm deeper than DALI Opticon 1 II.

Below you can see the front view size comparison of DALI Opticon 6 II and DALI Opticon 1 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 DALI Opticon 6 II is approximately 663.0cm2 / 102.8inch2 and base area of the DALI Opticon 1 II is approximately 359.6cm2 / 55.7inch2. The Opticon 6 MK2 requires 84% more surface area than the Opticon 1 MK2 which gives it a small disadvantage on placement in tight spaces.
