Test & measurement
The B452-AIR bookshelf speaker may be the little brother to the larger B652-AIR bookshelf speaker, but it packs a sonic punch! Try it on your desk, or as part of a compact, discrete yet impressive-sounding surround sound system. Like the B652, the B452-AIR is all about giving you the most performance for your money while offering a little something extra from the fantastic AMT tweeter.
What is an AMT?
AMT is short for Air Motion Transformer, which stands tall as a unique style of transducer in the world of speaker drivers. The AMT found in the speakers from Dayton Audio utilizes a folded Kapton ribbon diaphragm. This allows more air to move through the diaphragm with less effort and distortion. This creates a purer and satisfyingly dimensional sound as compared to a traditional dome-style tweeter.
Dayton Audio B452-AIR 4-1/2" 2-Way Bookshelf Speaker Pair with AMT Tweeter
Don't judge a speaker by its size! The Dayton Audio B452-AIR 4-1/2" bookshelf speaker is the smallest in the Dayton Audio family, but the sound is big. A newly-designed 4-1/2" polypropylene cone woofer with 4-layer voice coil achieves excellent balance and listenability when combined with the 1" AMT tweeter, for exceptionally rich and detailed sound from a small speaker. While cheap speakers use plastic enclosure parts to cut costs, the inexpensive B452-AIR uses a sturdy wood-composite cabinet that minimizes resonance and enhances warmth without sacrificing clarity.
The B452-AIR bookshelf speaker fits into a space only 5.5" wide and less than 6" deep, making it the perfect choice for desktop listening, or compact surround speakers in a home theater surround-sound system. A built-in keyhole wall hanger bracket makes it a breeze to wall-mount the B452-AIR in any desired location. For a room-filling listening experience with deeper bass that rivals larger full-sized speakers, the B452-AIR speaker also pairs perfectly with any of the excellent Dayton Audio powered subwoofers.
Anywhere you enjoy music, the balanced sound of the B452-AIRs add a new dimension of affordable enjoyment.
