I've enjoyed active speakers as my exclusive choice to live with for 23 years now. For the first 11 years I did the diy conversion of passive speakers. Using my own choice of amplification and active crossover. So my choice of amp. I tried lots of different amps because different amps made a difference. I tried a few different active crossovers because active crossovers make a difference. It was a good sounding system that impressed everyone who heard it.
Then 13 years ago I had a mishap with my active crossover. In a pinch with no music I resigned to buying a cheap pair of KRK Rockits to tide me over while i got my Accuphase active crossover repaired. I managed to find a used pair of KRK Expose E8B for a couple of hundred more than the Rockits i was looking at buying. For sale 20 miles from where I live. For sale at 20% of the retail price for the pair. I bought 'em. Not knowing whether I'd be convinced by a 8 inch woofer after living with a 15 incher for 11 years.
Got the Exposes home. Positioned them just to the outside of my diy activated Altecs. Never played the Altecs again. Not one song. Not one second of music.
I've used the Exposes for the last 13 years and I have never experienced a speaker which mirrors(or Exposes wink) the components which precede them in the chain so faithfully. After living with them for 13 years I still couldn't tell you what they sound like because they sound like everything you put in front of them. The same way that the image in a mirror faithfully reflects what is put in front of it.
I'd love to have better speakers than the Exposes, but I think that any complaints I'd have about the Exposes reflect more on the rest of the system. By the way, I'm completely won over by my system. No complaints. My last upgrade was a new cartridge(Audio Technica ART20) and that launched my system into another circle of satisfaction. The KRKs are far from the limiting factor. They blossomed with the introduction of the ART20. Just grew wings and took off.
So to go active you can diy. Choose the amps. Select amps which suit the drivers. Choose the active crossover. Experiment. The results can be excellent. Or you can find a well thought out pair of off the rack highly accomplished studio monitors which redefine your understanding of high fidelity. Or have none of that and hope that your amp plays well with your passive speakers. I was on the passive speaker and amp merry go round for 30 years. I'll never go back to passive. If I ever wanted to upgrade from the Exposes I would diy active (no DSP) using the Accuphase active crossover and some of the great amps I have lying around. There are some incredible drivers around now and I would start from scratch. Choose all the drivers myself and diy activate.
