This is a complete kit for professionally replacing a pair of surrounds on all AR-LST/2 Speakers.

• Assembled from components selected over the years while replacing the surrounds on many, many AR speaker drivers. This is not a generic surround replacement kit. The components and detailed instructions were selected explicitly for Acoustic Research LST/2 speaker. 
• There are two key components ensuring correct woofer performance; the foam surround must have the correct flexibility and roll diameter. If this is not correct, the stroke of the woofer cone will be limited and thus, the low bass notes.
• Additionally, shimming is necessary to guarantee that the voice coil remains centered in the magnetic gap. If you don't get this right, you run the risk of the voice coil rubbing on the magnet pole piece and causing distortion. We shim every woofer we repair. We are very good at this but never take the chance of not shimming and later discovering the rub after all the work has been done.
• This kit was utilized on the LST/2 Restoration depicted.
• The kit includes; a pair of foam surrounds, a set of shims for centering the voice coil (if you are going to go through the trouble of removing the woofer, go the extra measure and center the voice coil), a container of adhesive (It is strong, fast drying and dries clear.), an adhesive applicator bottle, a pair of dust caps that you literally drop in place when done and a step-by-step set of instructions specific to the AR-LST/2. You may find the cabinet sealer in department OTHER SPEAKER SERVICE PARTS(don't try and reuse that old, dried up sealer that's under the woofer frame, a sealed cabinet is key to those low bass notes).
• If you would prefer to have us do the job, you may ship the woofers to us. Email us for packing and shipping instructions.

If you don't have the allen wrench to remove the Spectral Balance Control Knob, it is listed in Dept. OTHER SPEAKER SERVICE PARTS. Use the AOL shopping cart and receive one invoice. Oh, this LST/2 is not included with the kit!

The following is a recent comment from on of our customers. Greetings Larry:

Just a quick message to let you know that I successfully completed refurbishing my friend's beloved speakers this past Saturday.

As we had both suspected, the surrounds were shot on both speakers, but more so on the one that I had mentioned was buzzing.  The new surrounds cured the problem and we both want to say that the dust cap covers lend a classy finish to the woofer.

Needless to say, my friend is VERY pleased with the outcome.  I suspect things may not have gone as smoothly if it was not for your kind assistance.

Thank you for everything!

Best regards,

Ken
