Hi John,
I'm going to immediately point you towards DNA products. DNA is David Nordschow Amplification. David founded Eden in 1976 and designed all their amps and cabs until he sold Eden in 2008 and left in 2009. In 2010 he brought new products from his newly founded company, DNA.
First off, I'll point you towards his amps. He has only a couple of them. Both are Class D amps and are not only light, 4.8-lbs for the 800 watt rms and 7-lbs for the 1350-watt rms one, but sound spectacular. Really clear and full with lots of bells and whistles including an onboard compressor with adjustable threshold and ratio. He came out with the DNA-1350 first and the DNA-800 about 3-years later. The DNA-800 has most of the features of its big brother but only has the normal effects loop instead of both the regular and the side-chain loop the 1350 has. Street price on the DNA-800 is $799. Street price on the DNA-1350 is ~$1499.
I was expecting to buy a DNA-800 myself, but agreement with the wife is I only use gig money to buy gear and I haven't played a gig since early January. I'm using a much heavier Eden amp that is really sweet but weighs ~36-lbs in its rack. Once we get past this pandemic, that's the first thing on my list.
For cabs, I personally bought the DNS-410 in 2015. That was going to be my be-all, end-all of cabinet purchases. It will handle up to 1400-watts rms both mechanically and thermally and will produce a max SPL of 137db. You wouldn't want to be anywhere near it at that level. I found that my 800 Eden amp drove it easily to gig levels both indoors and at outdoor festivals. I tried to turn the master up once to 10:30 on my 800-watt amp at an outdoor festival and was told to turn it down. So, no need to ever bring an 810 out because my 410 is already too loud. When playing outside in wide open spaces I can run it at 10 o'clock. Indoors, 9:30 is the max or I will start pushing people out of the room.
Problem I ran into with that 410 was that it scared the owners of small clubs when I rolled it in. So last year I went back and bought the DNS-210 figuring I'd use that for small and medium venues. The DNS-210 will handle 700-watts rms (both mechanically and thermally) and has a max SPL of 134db. It's a surprisingly loud cab and has the same clarity, articulation, fullness of sound, and the same tight and even lower bottom end than my DNS410 does. I now use it for all my indoor gigs.
So I can give you two recommendations. If you are going to be playing indoors only, that DNS-210 will handle every small, medium, and large indoor room (outside of stadiums). If you're going to play outdoors, especially outdoor festivals, I'd suggest the DNS-410. The street price on the DNS-210 is ~$849. The street price on the DNS-410 is $1049. With your budget of $2000, you can get either set up with the DNA-800 and come in under budget. If you went for his big brother, you'd be about $350 over budget.
Below is a video from Bass Musician Magazine.com that I've cued up to the part where they are demoing the features of the DNA-800 amp. They are running it through the DNS-210 so that's a good idea of the sound of the two of them together. If you take a look at the
DNA Artists on DNA's web site (yes I'm on there), you'll see a surprising number of them that use the DNS-210. I thought that was weird until I bought mine. Now it makes sense.
