EDIT: BLOWOUT PRICE REDUCTION! FREE SHIPPING! (lower 48 US states only) I [del]have[/del] had a total of five Acme Low B cabinets for sale: The two 8-ohm B4 SI and S1 box/SII internals are still available. Pics are below - All cabs are in great functional shape without any known issues and sound fantastic. There are some basic cosmetic issues, scratches and stuff, a little pilling on some of the carpet, particularly the older ones but not too bad. Nothing glaring our really obvious, visually. I have no prob with these cabs and am not selling them because I dislike them, I just need the cash as soon as possible, not to mention I have too many Acmes. And yes, I have used them all at once before and Low B4's availale: Acme Low B4 Series I - 8 Ohms - $299 USD Free Shipping! w/Castors, 1/4" Inputs only Acme Low B4 Series I - 8 Ohms w/Internals converted to Series II (crossover, woofers, tweeter) - $349 USD + Free Shipping! (no castors but Speakon inputs only!) Both of these B4's sound almost identical. I've always noticed very little, if any difference sonically between Series I and Series II Acme cabs to my ear and I've heard and owned several. I've even interchanged them simultaneously depending on the gig and couldn't notice a difference. The one with castors is a little older and sounds a little more mellow overall than the newer one, but I attribute that with age compared to the replacement components in the newer one. As I understand it, Andy Lewis @ Acme created the Series II initially because he could no longer source the tweeters on the Series I. So he took the opportunity to update the crossover and the appearance of the cab to an all black appearance.
