Triangle Signature Theta Bookshelf Speaker

The Triangle Theta Bookshelf speaker is part of the newest range from Triangle, Signature.

Offering amazing musical quality thanks to a 16cm driver with half roll suspension with excellent power and speed for a bookshelf speaker

The signature range also makes for a great home cinema experience. The Theta uses the same technologies as the other models within the Signature range meaning if you are setting up a home cinema system with this range they offer a great balance and are perfectly adapted for all types of movies. The Theta would make a suitable rear or for smaller systems a great compact front speaker with the matched Gamma as a centre channel. For a larger system you could match the Alpha or Delta Floorstanders.

The Signature range is manufactured in France and carries the same luxury craftsmanship we've seen from the Magellan range. The cabinets for the Signature range are made up from 7 high-density fibreboards, bent with a press, resulting in a thickness of 21mm. This high-density cabinet helps reduce the vibratory behaviour resulting in a much better sound quality produced.
