Description
Offered for your consideration is a pair of ADVENT 10 inch long-throw woofers removed from my ADVENT 4002 speakers, USA-manufactured in 1983. ADVENT designed these woofers to use a larger basket than the typical 10” platform for its greater depth and capacity for cone excursion. Its the same woofer that ADVENT used in the period 5002 and 5012 speakers. Earlier square-magnet versions were found on The Advent Loudspeaker, ADVENT/1, and others in the mid-to-late 1970’s, but this round magnet version should be perfectly compatible (as long as the basket/cone are the same). Regardless, the buyer is responsible for accurately verifying the suitability of these woofers for any application other than the ADVENT 4002. So, please see my large photos, the measurements, and read the remainder of the description to decide if these capable, hard-to-find ADVENT mid/bass woofers should be yours. These ADVENT woofers are in clean, very good-to-excellent condition. The sturdy, ribbed paper cones are structurally flawless and the voice coil dustcaps are dent-free perfect. Also, the steel baskets are in nice shape with no dents, just some blemishes to the flat black finish on the mount flanges as pictured. Plus, the sizeable magnets have no chips or oxidation. Most importantly, the aged original polyurethane foam suspension was just replaced with modern polyether foam surrounds in the correct narrow flange lip profile designed expressly for these ADVENT woofers. The main drawback to most U.S. and foreign-made speakers from the early 1970’s to 1990’s was the use of foam surrounds for woofer cone suspension. Though foam offers better excursion than coated linen and rubber, it invariably rots and/or disintegrates in 10-20 years no matter what climate you live in. These stalwart ADVENT woofers were no exception—the surrounds had dried out, fell apart, and sidelined the terrific ADVENT 4002 speakers for some 20 years. Some of you have replaced speaker surrounds before, so you know that it’s a time-consuming process that takes a great deal of patience and a steady hand. First, I cleaned the cone edges and basket flanges to remove the old gummy foam and stubborn factory adhesives, which also takes some time to do thoroughly, and then glued the inner surrounds to the cones. On this woofer design, the inner surround lip sits under the cone edge instead of on top the way most do. Since the glue must be applied first, stretching/tucking the surround under the cone, and adjusting to a precise fit, can make a big mess on the cone if not done with the utmost of care. Fortunately, I’ve had lots of practice. Next, I glued the outer surround lips to the basket flanges after careful voice coil centering to verify no rubbing or distortion during play. Now these woofers are in great shape once again; perhaps even better than new with the improved polyether foam surrounds of today! Most importantly, these woofers have been fully tested after the new surrounds were installed and sound great—very clear with fast, detailed midrange, and solid bass response. I also tested their DC resistance at a closely-matched 4.7 and 4.8?, respectively, consistent with a nominal 8 ohm driver rating. Lastly, the basket flanges measure 11?” across (12½” on the diagonal), they stand just over 5”, and the mount holes are spaced 8¼” adjacent / 11?” on the diagonal, c-t-c. These are a great find if your 4002, or other suitable ADVENT speakers, have been sitting idle due to decayed surrounds, a blown woofer(s), etc—your cherished speakers will be sounding their finest once again in no time! So, as pictured and described, this pair of ADVENT 10” woofers, with painstakingly refurbished surrounds, is offered at a competitive price.
