I used a Cerwin-Vega 1x18" bass-reflex (not folded horn) cab for a few months but gave it up. It filled small rooms with bass pretty well, but that's about all I can say for it. If you walked into the room and listened to the band, you could tell there was a bass player, but you couldn't necessarily pick him (me) out of the mix. It created more of a "bass wash" than separate, distinct notes. Tough to describe. Also that thing was a huge current sink. Watch out for that. Some 18s are very inefficient and need hundreds of watts to get anything close to dynamic/punchy. It will depend on the box, too. I drove that cab with a 220 watt-per-side Cerwin Vega power amp (1 channel) which routinely went into thermal runaway trying to feed that 18. A Sunn Coliseum worked marginally better but still wasn't enough to make it do anything meaningful. Half the problem was the driver was 8 ohms, so transistor amps were automatically at a disadvantage when it came to power delivery. Back then (mid-late 1970s) there were no transistor amps that could do more than maybe 150 watts at that impedance. And I didn't have the money or the hernia insurance for an SVT but that wouldn't have worked anyway because I would've had to buy a second cab to get the proper transformer match. Eventually I said come on, what the heck am I trying to prove here, and went to a different cab.
