When I got my 70's Ampeg V4B I was frustrated with it's 26.5 inch width. I like matching heads and cabs and I don't like to see the head hanging over the sides of the cab. Most Ampeg cabinets are 24 inches wide. Here's a list of all the Ampeg bass cabinets that are at least wide enough for the V4B to sit on without hanging over the sides. Edit: the following list has been updated to include additonal cabinets discovered in thread discussion. Vintage, period-appropriate cabs: V4B - a folded horn 2x15. 48"H x 26.5"W x 24"D V6B - a direct-radiating, ported 2x15. 41"H x 27"W x 15"D B25B - a direct-radiating, ported 2x15. 40"H x 29"W x 12"D B40 - a direct-radiating, sealed 4x10. 30"H x 27"W x 14"D Cabs that were made after the original V4B head was discontinued, early SLM-era cabs without white piping: SVT-18E (not the SVT-18) - a direct-radiating, ported 1x18. 24”H x 27”W x 16”D SVT-410E - a sealed 4x10 (no horn like the later 410HE has). 24”H x 27”W x 16”D SVT-1510E - a direct-radiating, ported 1x15 with a sealed 1x10 27" wide, height and depth unknown at this time Cabs made after the orginal V4B head was discontinued, SLM-era cabs with white piping: V4B (V4BH-era) - a folded horn 2x15. 48"H x 26.5"W x24"D SVT-412HE - a direct-radiating, sealed 4x12. 29.25"H x 27.5"W x 18.25"D There may be some MTI-era cabs. Maybe the same ones as the three early no-piping SLM-era cabs listed above. If you think I missed something, please say so.
