Dali Opticon 6 Mark 2 Review: Dual Tweeters, Deep Bass, and a Fair Price

Introduction

The Dali Opticon 6 Mark 2 is a floorstanding speaker that sits at the entry point of Dali’s dual tweeter family. It arrives at around $2,500 per pair and is often available for less when discounted, which makes it one of the more interesting propositions in its price band. It is not a neutral speaker, and it is not built for every taste. It is built for listeners who want top end clarity, a warm midrange when the recording calls for it, and bass that hits hard when the music demands it.

This guide covers what the speaker does well, what it asks of you in return, and which listeners are likely to be happy with it over the long term.

Who This Speaker Is For

The Opticon 6 Mark 2 rewards listeners who care about detail. If you enjoy hearing the air around a vocal, the shimmer and decay of a cymbal hit, and the texture of a well recorded room, this speaker is aimed squarely at you. Rock, metal, punk, and grunge listeners in particular will find the presentation lively, dynamic, and punchy.

Two specifications matter before you buy. Sensitivity is rated at 88 dB with a nominal impedance of 4 ohms, so the speaker asks for an amplifier with genuine power on tap and one that is comfortable and stable driving a 4 ohm load. A modest amplifier will run out of headroom quickly once the music gets loud.

It is also worth saying plainly that this is not a neutral speaker. It has a distinct character, and that character is the main reason to buy it.

Main Strengths

The headline feature is the tweeter arrangement. A 1 1/8 inch ultra light textile dome tweeter sits below a 1 3/4 by 11/16 inch ribbon tweeter, and the two work together rather than one replacing the other. The ribbon contributes openness, detail, and a sense of air. The dome contributes natural tone and warmth. The result is treble with shimmer and decay but without the hardness a metal dome can introduce.

Below the tweeters sit two 6.5 inch wood fibre cone woofers in a deep burgundy finish that is instantly recognisable as Dali’s house look. The cabinet is MDF with dual ports on the rear, and the speaker runs a 2.5 way configuration with crossover points at 800 Hz, 2,200 Hz, and 14,000 Hz.

Vocals are a genuine strength. Rich, deep voices keep their weight rather than turning cool and thin, which is a common trade off in ribbon tweeter designs. Male and female vocals hand over without an audible seam, and sibilance stays under control even on bright recordings.

Bass, Dynamics, and Scale

Bass is the area that needs the most context. The rated low frequency rolloff is 49 Hz, which is high for a floorstanding speaker. If your music has meaningful content well below 50 Hz, or if you watch films with explosions, gunfire, and deep space rumble, plan on adding a subwoofer.

For rock, metal, punk, and similar material, the bass proved more than sufficient. It is clean, fast, and never muddy, and it hits hard when the track calls for it. There is one important caveat: these speakers benefit from a break in period. Out of the box the sound leaned forward in the midrange and the top end, and the low end filled in over the first few days of listening. Once that settled, the presentation became noticeably more dynamic and lively.

Things to Consider Before Buying

The character of this speaker means it will not suit everyone. If neutrality is your priority, or if you want a speaker that disappears entirely behind the recording, this is probably not the right choice. It has personality, and it makes that personality known.

The 49 Hz rolloff is a design decision rather than a flaw. It leaves room above the subwoofer range, which makes it easier to integrate a sub and tune the low end to your room instead of fighting a floorstander that already reaches deep on its own.

Physically, the speaker is a manageable size at around 42 lb, roughly 10 inches wide and 39 inches tall. It is large enough to read as a serious floorstander without dominating a normal living room.

Placement, Amplification, and Room Correction

Placement has a real effect on this speaker. Toed in directly at the listening position, the top end can become too much. Angling the speakers so they fire straight into the room, with the listener slightly off axis, brought the treble in line with the bass and produced a more enjoyable balance. Imaging survived that change well, with a solid centre image even without a centre channel in the system.

Room correction deserves a note. When automatic room correction was applied across the full range, it lifted the midrange too far and took away much of the punch at the bottom, which left the speaker sounding neutered. Switching it off restored the character. If you do run correction, limiting it to the lower frequencies is a more sensible starting point, though the outcome will depend on your room.

How It Compares With Other Floorstanders

Dali’s own Rubicon 6 sits above the Opticon 6 Mark 2 in the range and brings a more refined enclosure finish along with a substantially higher price, since the Opticon 6 Mark 2 costs less than half as much as a pair of Rubicon 6 speakers. The Q Acoustics 5050 is a strong alternative in the same price region, but the Opticon 6 Mark 2 holds the advantage on top end clarity and on the way its 49 Hz rolloff leaves room to dial in a subwoofer. Listeners who like this general character but want to spend less should also look at the Emotiva XT1, which offers a similar presentation at roughly half the price.

Buying Advice

At around $2,500 per pair, and frequently less when it is discounted, the Opticon 6 Mark 2 delivers a combination that is hard to find at this price: a dual tweeter array shared with Dali’s more expensive models, two wood fibre woofers, and a tuning that prioritises life and energy over flatness.

Before you buy, make sure your amplifier is comfortable with a 4 ohm load and has enough power to drive an 88 dB speaker properly. Decide whether you need a subwoofer for your listening habits, and give the speakers a few days of use before you judge the low end. If you value top end clarity, punchy dynamics, and a bit of character, this is a speaker worth shortlisting.

Conclusion

The Dali Opticon 6 Mark 2 is not a universal recommendation, and it does not try to be. It is a speaker with a clear point of view: open and detailed treble, warm and articulate vocals, and bass that hits hard without pretending to reach the bottom octave. Listeners who share that preference will find a great deal to like here, particularly at the price it sells for.
