When I was considering new speakers, I thought about those utilized those in mixing and recording studios. It seemed a good idea to seek the same sound that recorders or professionals used. ATC has long history in what many professionals used to make the mixes and final cuts. I looked at the pro series and quickly realized they were designed for much closer distances (than my home) such as recording studios. Coming from ATC, this is stated of every model in the pro series:
- Ideally suited to:
– critical near-field listening applications in all control rooms
– LCR surround monitoring in small-to-medium control rooms.
– surround channels for immersive audio (Auro 3D, Dolby Atmos, DTS-X)
They may be better, but I choose the Entry series for my home. I saw many good reviews for the ATC SCM 40 and its accuracy. Their Mid 75mm ATC Soft Dome is the most incredible midrange driver I have ever heard. They are incredible accurate, I continue to hear new items in recordings listened to for decades. Crazy things such as distinct guitar picks or fingers, and more so, bass fingers resulting in immediate beautiful sound. Touching the drums with one's hands is another. With a sealed base design, they are extremely tight and mesh perfectly with my sealed pair of JL Audio F113 V2. I love tight deep base. The blending and separation of the bass drum and guitar become intriguing.
My input would be to consider the optimum distances for your application. The ATC Entry line for the SCM 40 was extremely impressive.
