Monoprice Alpha 6.5 Inch 2-Way In-Ceiling Speakers (Pair) - Carbon Fiber Woofers, Paintable Magnetic Grille, High Efficiency for Home Theater & Background Music - Black/White - Perfect for Living Room, Bedroom & Home Audio Systems

Used 4 of these as Dolby Atmos height ceiling speakers in our Home Theater project. Everything about these speakers is what you'd want in a project like this: Good value, good quality, easy installation, great sound.The Audyssey speaker calibration in our Denon AVR showed these able to handle down to 40hz, and the EQ curve was surprisingly flat. Since they are Atmos speakers, I set the low-pass to 60hz and let the AVR apply the measured EQ curve. All 4 speakers had practically identical EQ curves and volume levels to each other, which should be expected but unfortunately is not always the case with value-priced speakers.The magnetic grills are a great design that hold in place tightly, but remove very easily with no forcing or drama.There's a treble attenuation switch that remains accessible behind the grill without removing the speaker that lets you tone down the tweeter by a few DB if you need this for your application.The very sturdy terminals can take any kind of wire, spade or banana plug you care to use. They have very strong springs and are gold plated.No rattles, no flatness, deadness or punchiness - just clean Atmos height goodness that makes overhead sounds come to life.Very pleased - I would buy these again without reservation.
