Just picked up this pair of old cabinets with a single Jensen Special Design 12" speaker wired direct to external posts. Inside dimension of cabinet is 16 3/4" W X 23 1/4" H and 15 1/4" D. Numbers on the Jensen speakers - 220113 : 401-31-C6856 : Input 16 ohms. Looks like cabs have a cutout of about 10" X 3 1/4" for a horn? Has a bottom port of about 3"-4". If anybody has any info it would be appreciated. Thanks
