Crafted for Your Ears and Your Eyes
As you would expect from a French company that is into design, the Theva models have more choices than basic black on every speaker except for the surround models. You can choose from: gloss black with a matching gloss black front faceplate, a light wood finish with an ivory front faceplate, and a darker wood with a gray-colored front faceplate. Each speaker includes a magnetic grill that covers most of the front.
If you choose to go with the grills off to show off the really cool slate driver material, you’ll find the Focal logo screen printed around each driver ring to display your choice.
In a change from Chora, Focal moved the ports to the rear of the speakers. In our opinion, this created both a pro and a con.
Pro: It allowed them to change the cabinet design to make them skinnier, which could be a big plus in some rooms.
Con: With a rear port, you will need them further away from a wall, as they will interact negatively with being close to a rear wall or cabinet.
Innovation in Every Note
Innovation abounds in the new Theva models.
If budget and space were no object, an ideal home theater system would comprise identical full-range speakers throughout. This would ensure all the surround effects sound the same, providing an immersive movie-watching experience. However, in reality, this is not practical. The next best option is to use speakers with the same type of drivers, crossovers, and cabinet construction to ensure a consistent sound. The new Theva speakers have identical tweeters and varying sizes of Focal's cutting-edge slate midrange/woofer, offering unparalleled audio quality.
The Theva employs Focal's renowned TNF tweeter, which was previously used in the Chora series. This exceptional tweeter is also found in more expensive Focal models, thanks to its proven performance and use of aluminum and magnesium. Focal has been utilizing inverted tweeters in its designs for over two decades and has been able to fine-tune this design to deliver the best possible sound.
During the development of their luxury Grand Utopia series, Focal devised a groundbreaking method of using Poron - a material with shape memory - as the suspension between the dome and bracket. This ingenious application of Poron significantly reduces distortion in the 2-3K range, by a factor of three, and can be found in the new TNF tweeter.
While there's no definitive "right" or "wrong" way to design a tweeter, it's hard to argue with Focal's decades of engineering expertise. With over 20 years of experience utilizing inverted domes, Focal continues to refine and improve this technology, making it a trusted and innovative choice for audiophiles worldwide.
They also had a goal with the TNF tweeter of improving how linear the sound is off axis. This is especially important for home theaters in media room situations where the viewers may not be in the sweet spot. Focal improved the waveguide to give them a very wide and linear dispersion pattern.
When you first see a Theva with its grill off, you will be struck with a very unique-looking woofer. The history and tech behind this is pretty interesting. Focal, like a lot of great speaker companies, has been experimenting with combinations of materials to improve performance. They decided to use an idea from the aviation industry and combine carbon fiber with plastics. After lots of trial and error, they discovered a magical combination of recycled carbon fiber held together with a thermoplastic polymer. Instead of weaving the fibers, they got better performance with them all going in the same general direction and held in place by the polymer. Can you imagine what it was like testing all those materials? Quite loud, we’d imagine.
Focal then had to design special machines to create these unique drivers at their factory in France. The random nature of the way the strands are put into the polymer creates a look very similar to slate, which is where they came up with the name Slatefiber for this new driver material. It is very light, extremely rigid, and highly damped, which are all things you aim for in a midrange or bass driver. No two are exactly alike, which is why we love these with the grills off. These first came out in the Chora models and are in the updated Theva series as well.
While the Theva shares the same drivers as the Chora series it replaces, Focal did make improvements to the internal crossovers and cabinet bracing for even better performance.
