Our exclusive refoaming and coil alignment process assures you of original performance. We have 49 years experience, including the design of the Infinity-Watkins woofers, which we have in stock. See below.
What you should know about refoaming: Proper refoaming is not as simple as one might think. The foam surround is attached to the cone, and the rear of the cone is attached to the voice coil of the speaker, making all three parts a single entity . Thus the outer part of the surround must be positioned correctly on the metal frame to align the coil in it's magnetic field, which is located between two metal pole pieces. There are two ways to do this in common practice: 1. Push the surround/cone/coil assembly around until you don't hear the coil scrape the metal poles. This is akin to blindly driving your car down the alley until you don't hear the fender scrape a wall, and does not center the coil in the magnetic field where it belongs for optimum performance. It can also leave such little clearance that the slightest shift during usage can cause the coil to rub a pole piece, requiring that the refoaming process be redone. 2. The other method of aligning the coil requires cutting out and destroying or mutilating the center dome in the cone in order to access and align the voice coil with shims. This requires replacement with a new and different dome, as original domes are not available for older speakers. The dome however, is a critical part of the original design, as it's stiffness, shape, and porosity (openness to air flow) are crucial to bass response.
OUR METHOD: We leave the original dome and it's attachment to the cone intact by aligning the coil electronically in the exact center of the magnetic field (centered between the metal pole pieces). This guarantees that after repair the speaker will sound the same as when new. Another advantage with our method is that it compensates for any rear suspension (the corrugated piece behind the cone) change of shape that might have occurred over the years. With our method of exact centering of the coil you are assured of both original and long-term performance.
Other advantages of dealing with Watkins: We use polyether foam. It lasts three times longer than other foam. Speaker repairs are refoamed with Airflex adhesive (it cures flexible). Speakers are refoamed and returned to you within three working days. In business 49 years, and all repair and speaker refoam is guaranteed. Woofer repair including dual drive is overseen by Bill Watkins.
