Well, all of my band-mates have returned from their various vacations and I finally got a chance to use my new NV 425. I, and my band-mates, was very impressed with the cab! Gear: Amp: Aguilar DB 728 Pre: Demeter HBP-1 Bass: Reverend Rumblefish I bought the NV 425 to replace my Mesa Powerhouse 2X10 and 1X15 cabs. The speaker configuration, 3X10 +1X15, I thought was a perfect match for a replacement to the Mesas and a compliment to my Whappo Jr. I was right. This is a completely different animal than the Whappo and I couldn't be happier! I thought I was going to have to spend a lot of time re-EQing my rig for the new cab since it does not have a high-end driver (tweeter as the kids say these days). I was wrong. The cab sounded great with my normal settings. With just a little tweak here and there I was able to immediately establish a very cool tone. The sound is. . . . . incredible. The lows were so full and rich I was stunned. Now, we practice in a large warehouse and the 425 literally filled the place with sound. I may be a little touched in the head, but I was getting this really awesome 3-D sound from the cab. It's a little difficult to describe, but it was producing a sound that radiated in a way I have never really heard from a bass cab before. This may be do to its sealed design, but I am not sure. I was very surprised at the smooth, rich high-end that the cab produces. There is no need for a "tweeter" as the 3X10 configuration reproduces upper frequencies very well. The 425 is a remarkable cabinet in every way. It seems so simple in design, but the tonal qualities are anything but simple. It impressed people who have very little idea of what a good bass tone is, and impressed me to no end. I recommend this cab to anyone that wants to work with a vintage vibe but from a 21st century approach. Now I want to try the 2X15! I want to thank Juan Ortiz and his Basses Electric & Acoustic for bringing this great cab and me together. Juan has a full line of Bergantino cabs and is a great guy to deal with. Of course, I must give Jim Bergantino a tremendous pat on the back for his awsome design. Keep up the good work!
