Thought I'd drop in and post a picture of my 2155CF. I upgraded to the Eminence APT80 tweeter and really like the mids that Faital 5" adds. Nick said "Once you hear those mids through that 5" Faital you won't want to move that switch back to 2-way". He's right. That Eminence 3015/Faital M5N8-80 match is stellar. The lows are really tight and punchy for a box loaded with two 15's and this sounds great with my Streamliner 900. I did the NOS 5751 tube swap in position 1 which tames the bloom and improves the mid balance of this amp. This cab can get L-O-U-D and I run the master volume lower than with my other cabs. It's got solid and percussive lows with good articulation and sweetness to the mids but can snarl if you want it to. Loving this matchup with both my Valenti PJ5 and Carvin SB5000 basses.
