The only active speaker I heard that I really liked was the MBL101s. In second place, the Legacy Aeris. I have listened to Avant-garde and active Klipschorns previously, but they did not make me want to jump into the active speaker lifestyle. Note, I stated that the Legacy Aeris and MBL101 were the best active I heard, but not the “BEST” I heard. That testament goes to my recently acquired non active Classic Audio Loudspeakers T1.5 reference. While looking for my next big speaker splurge, and with a substantial budget to help, I listened to everything. To my ears, the T1.5 reference brought to my attention, the immediacy, delicate voice, and instantaneous snap of drums that to my ears, made music sound more realistic and live. To my ears, I could sense the artifact of DSP used with the Legacy Aeris and it just seemed to me that it needed more work and tweaking to get the sound right. This was with the Wavelet DSP device.
Like all things in this hobby, such as tube rolling, subwoofer integration, cartridge and tonearm matching, it takes some work to optimize your system. Going active may have its merits, but it also requires a certain amount of work to get it right. Some people may feel more comfortable at measuring each driver for latency and delay, roll off, phase etc., while others not. Simply powering each driver in a speaker without actually measuring the in-room response could cause other problems. So, it does take more time and effort initially to get active setup in a way that would overcome room speaker artifacts as described above. But, one must do the same with non active speakers as well.
I don’t know if spending time going active, researching amps and/DSPs, measuring each change is worth my time and effort when I have such really great satisfying results with my non active speakers. Granted, I have measured in room response and treated frequency anomalies with appropriate diffusers or absorption material as needed. I would suggest anyone serious about this hobby to at least take the time to measure the room to identity problem frequencies. My room is also built to soundproof specs which also increases my listening pleasure.
At the end of the day, I can’t say that I would disagree with anyone wanting to go active, it would be different in other ways. If it works for you, go for it. It’s not for me, for the reasons stated above, I am out.
