Product Summary

The DALI ALTECO C-1 is a highly versatile loudspeaker designed for multiple uses in both hi-fi and home cinema systems. This listing is for a pair of DALI ALTECO C-1 speakers, making it ideal for Dolby Atmos height effects, surround channel duties, discreet stereo wall mounting or even nearfield desktop listening.

Each speaker is built around a 4.5-inch low-loss wood fibre woofer and a 21 mm ultra-light soft dome tweeter. This combination delivers clear dialogue, precise effects placement and a detailed, open sound that works equally well for music and film soundtracks.

The distinctive angled cabinet and DALI’s Dual Sound Mode give the ALTECO C-1 impressive flexibility. In 'UP' mode it can project sound for height-channel use, while 'DOWN' mode is designed for more direct listening when used on-wall or closer to the listening position. This makes it an excellent solution for systems where space, placement and flexibility all matter.

Its compact wedge-shaped enclosure also makes it easy to position on top of existing speakers, mount on a wall or integrate into smaller rooms without sacrificing the spacious, wide-dispersion sound DALI is known for.

Our Trustpilot reviews

★★★★★
What an amazing company. Anna in the Glasgow branch has been so informative and helpful with my order. Sam in the Aberdeen branch has an incredible knowledge of older amps and speakers.
Alan

★★★★★
I bought a full system from the Aberdeen shop. Christian was very attentive throughout the whole process. I found that all the staff in the shop were both knowledgeable and helpful. I would strongly recommend Holburn Hi-Fi to anyone thinking about buying a full or part Hi-Fi system.
Peter

★★★★★
Jesse is very professional and always happy to help in the Glasgow Audio store. He is very knowledgeable about the products. Highly recommend.
Kyle

★★★★★
The guys at Holburn Hifi were fantastic from start to finish. Explained everything clearly and in simple terms which I really appreciated as I was lost amongst all the info I had seen online. There was no hard sell and certainly an understanding of my budget. I can’t recommend Holburn Hi Fi highly enough. Thanks to Ian, Sam and Christian.
Richard

★★★★★
Dropped in not really knowing what I wanted. Sam was most helpful, steering me towards a solution, and avoiding going over the top. From that we moved on to updating our wifi coverage towards a network. Here, Alain was equally helpful.
