Dynaudio Contour 25Ci Centre Channel Speaker at Vinyl Sound Buffalo, NY USA

The Contour 25Ci is a 2.5-way centre channel loudspeaker from Dynaudio (Skanderborg, Denmark), available at Vinyl Sound in Buffalo, NY, USA. Part of Dynaudio's Contour i series, it is the dedicated centre channel companion to the Contour 20i, 30i, and 60i, architecturally equivalent to a Contour 30i turned on its side with the 28mm Esotar2i tweeter with Hexis positioned centrally between two 18cm MSP cone drivers with large-diameter aluminium voice coils and aramid-fibre asymmetric spiders. Sensitivity is 87 dB, impedance is 4 ohms, IEC power handling is 300W, and frequency response extends from 35 Hz to 23 kHz. The 2.5-way crossover at (300)/2,200 Hz uses the same simplified second-order topology as the Contour i series, built at Dynaudio's Skanderborg factory to furniture-grade quality standards.

Esotar2i Tweeter with Hexis and Dual 18cm MSP Drivers

The Contour 25Ci shares the same driver and crossover architecture as the Contour 30i, with the Esotar2i tweeter positioned centrally in a horizontal configuration flanked by two 18cm MSP cone woofers. This layout keeps the tweeter on the acoustic axis regardless of whether the centre channel is placed above or below a display, maintaining the horizontal dispersion pattern that a vertically oriented centre channel compromises when tilted toward the listening position. The Esotar2i is the upgraded version of Dynaudio's Esotar2 tweeter introduced with the Contour i series refresh, gaining the Hexis inner dome for rear-wave resonance control, a larger rear chamber derived from the Core professional monitor range, and a more powerful neodymium magnet system. These revisions produce a flatter measured high-frequency response, lower harmonic distortion, and improved transient speed compared to the original Esotar2. Both 18cm MSP drivers use large-diameter, long-throw aluminium voice coils and asymmetric aramid-fibre spiders, the same updates applied across the full Contour i woofer family. The asymmetric spider design with varying-width corrugations provides more consistent excursion control across the driver's operating range than a conventional symmetric spider, and the aramid-fibre material improves acoustic response over the previous Nomex design. Ferrofluid in the tweeter's voice coil gap dissipates heat and absorbs mechanical shock, improving sustained power handling and extending long-term reliability under demanding cinema use. The 2.5-way crossover at 300 Hz and 2,200 Hz uses second-order networks and has been simplified for the i generation by removing impedance correction circuitry, made possible by the improved inherent linearity of the Esotar2i and updated woofers. Internal damping has been renewed using lessons from the Evoke and Confidence development programs.

Furniture-Grade Construction and Contour i System Integration

The Contour 25Ci cabinet is built to the same furniture-grade standards as the upright Contour i speakers, with curved edges and an inset aluminium front baffle consistent with the series aesthetic. New driver baskets, redesigned from the 2016 Contour generation, are built to tighter dimensional tolerances for improved driver alignment and long-term mechanical stability. The Contour 25Ci is specifically voiced to integrate tonally with the Contour 20i, 30i, and 60i, ensuring that dialogue and centre-channel content in a multichannel system shares the same timbral character as the front left and right speakers. Because the Contour i series is also used in stereo two-channel configurations, the Contour 25Ci meets the same performance standards as its upright siblings rather than being engineered to a lower specification as a supplementary channel. At 750mm wide, it accommodates placement on AV furniture below a large-screen display or on a shelf above one, with the horizontal driver configuration maintaining acoustic axis alignment in either position.

Frequently Asked Questions

What is the Dynaudio Contour 25Ci?

The Dynaudio Contour 25Ci is a 2.5-way centre channel loudspeaker built in Skanderborg, Denmark, as part of the Contour i series. It is architecturally equivalent to a Contour 30i laid horizontally, with a 28mm Esotar2i tweeter with Hexis flanked by two 18cm MSP cone drivers with aluminium voice coils and aramid-fibre asymmetric spiders. Sensitivity is 87 dB, impedance is 4 ohms, power handling is 300W IEC, and frequency response extends from 35 Hz to 23 kHz. It is designed to integrate tonally with the Contour 20i, 30i, and 60i.

Which Dynaudio speakers does the Contour 25Ci pair with?

The Contour 25Ci is designed to integrate with any combination of Contour i series loudspeakers as front left and right channels, specifically the Contour 20i standmount, the Contour 30i floorstander, and the Contour 60i floorstander. All Contour i models share the Esotar2i tweeter with Hexis and the same generation of MSP woofer, ensuring consistent tonal character across all channels. The Contour 25Ci can also be paired with Dynaudio's Sub 3 or Sub 6 subwoofers for additional low-frequency extension in large home cinema rooms.

What is the Esotar2i tweeter with Hexis in the Contour 25Ci?

The Esotar2i is Dynaudio's upgraded version of the Esotar2 tweeter, introduced with the Contour i series in 2020. It adds the Hexis inner dome, a fixed secondary dome behind the 28mm diaphragm that suppresses rear-wave resonances and smooths the high-frequency response. A larger rear chamber, derived from Dynaudio's Core professional studio monitor series, provides additional operating room for the dome at higher excursion. A more powerful neodymium magnet system improves sensitivity and transient speed. The crossover was also simplified for the i generation, with impedance correction circuitry removed because the Esotar2i's improved linearity manages this intrinsically.

How should the Contour 25Ci be positioned relative to the display?

The Contour 25Ci can be placed either above or below the display screen. Its central tweeter placement ensures the Esotar2i remains on the acoustic axis with the listener in either position without requiring the speaker to be angled. When placed below a display, the speaker should ideally be positioned so the tweeter is at approximately seated ear height. When placed above, a small downward tilt toward the listening position can improve dialogue focus. Dynaudio recommends at least 20 cm of clearance behind the speaker for the rear bass reflex port to function cleanly.

What AV receiver or amplifier channel is recommended for the Contour 25Ci?

The Contour 25Ci is rated at 4 ohms with 87 dB sensitivity and 300W IEC power handling, requiring an AV receiver or multichannel amplifier channel rated for 4-ohm loads. Most mid-to-high-tier AV receivers from Denon, Marantz, Yamaha, or Anthem rated at 100W or more per channel into 4 ohms are adequate. For the best performance, a dedicated multichannel amplifier with individual channel ratings into 4 ohms is recommended, particularly in large rooms where the centre channel carries a high proportion of the total output during film dialogue and action sequences. Dynaudio engineers the Contour i impedance curves to be more forgiving than the nominal 4-ohm specification suggests, making the Contour 25Ci compatible with a broader range of AV equipment than the rating implies.

Where can I buy the Dynaudio Contour 25Ci in Buffalo, NY or the USA?

The Dynaudio Contour 25Ci is available at Vinyl Sound in Buffalo, NY, USA. Vinyl Sound is an authorized Dynaudio dealer serving customers in Buffalo, Western New York, and across the United States. Contact Vinyl Sound Buffalo to arrange a demonstration or to discuss multichannel system configuration with matching Contour i speakers.

How does the Contour 25Ci differ from the Evoke 25C?

The Dynaudio Evoke 25C is the centre channel speaker for the Evoke series, using the Cerotar tweeter with Hexis and a pair of 14cm MSP Esotec+ drivers in a smaller cabinet. The Contour 25Ci uses the higher-tier Esotar2i tweeter with Hexis and a pair of 18cm MSP drivers with the full Contour i woofer specification, in a substantially larger 750mm-wide cabinet reaching 35 Hz at -3 dB. The Contour 25Ci's 300W power handling, 87 dB sensitivity, and 4-ohm impedance are matched to the Contour i series upright speakers, while the Evoke 25C is voiced and sized for the Evoke range. Buyers with Contour i front speakers should use the Contour 25Ci for tonal integration.
