This listing is for a pair (2 surrounds) of 10" foam surrounds specifically designed for the NLA (New Large Advent) Advent

speakers. These fit the 2nd style 10" Advent woofer without the Masonite trim ring. These are the premium USA made foam surrounds.

 I have refoamed at least 20 pair of NLA's using these surrounds & they work great.

 If you need the surrounds for the OLA's with the Masonite trim ring, I have those available in a separate listing in my eBay store.
