Upgrade your purchase with these options:
The metal face plate on your speaker’s dome tweeter can cause higher frequency reflection. Fit our oval Focus Rings to your speakers to help reduce this reflection to give a clearer and more focussed sound!
Made from felt for effective absorption, they are supplied in pairs and have a self adhesive backing for easy fitting. Designed to be used without speaker grills.
HI-FI WORLD March 2011 Review
A small item with a big impact seems to be the conclusion of the latest review of our Focus Rings. In their March 2011 edition, Hi-Fi World tested the rings on a number of speakers and found that “they made a difference in every case” What’s more, in the case of Adam Smith’s (the reviewer) own Ferrograph SI speakers, “the effects are quite ear-opening”.
He clarifies this with more detail, such as “the speakers’ entire top end seemed to snap into focus” and “the soundstage itself seemed better locked into place and, even in direct sonic terms, there was a delicate hint of extra crispness to everything”.
In conclusion, Adam states that “these seem a bit of a bargain” and that “for a simple but non-permanent change that gave a surprisingly vivid effect, I would strongly recommend giving them a go”.
1. To determine the correct fitting of the Focus Ring (either vertical or horizontal) simply place the oval ring around your tweeter without removing the backing paper. For loudspeakers with a wide front baffle vertical is preferable.
2. Gently peel the backing paper and carefully fit the focus ring around the tweeter ensuring the dome of the tweeter is central to the oval. It is important that you do not deform the oval shape.
3. Once in place, gently press to ensure a secure fit. Since the adhesive is formulated for a strong bond you may find it difficult to remove once fitted. Note:
With speakers placed close to hard reflective surfaces you may hear a reduction in high frequency energy, due to a reduction in early sidewall reflection. At first you may feel that the sound has become 'dulled'. Don't panic! Once you become accustomed to the change, you will hear a noticeable improvement in clarity, depth of image and soundstage focus. The degree of improvement will vary depending on the design and quality of the tweeter.
