audio technica / AT-SP3X

audio technica / AT-SP3X is a 3-inch powered bookshelf speaker.

■Powered bookshelf speaker

■Dedicated tuning realizes rich full-range audio
A 3-inch (φ76mm) woofer and a 1.1-inch (φ27mm) tweeter are combined, the enclosure's acoustic design is added, and the sound quality is specially tuned using the built-in DSP. Delivers a flat, clear sound with excellent balance. Especially when used with an Audio-Technica record player, the sound of records can be reproduced faithfully.
■Impressive sound beyond imagination from a compact bookshelf speaker
Despite its compact size of 125 mm width x 200 mm height x 136 mm depth, it achieves an output of 30W, which is comparable to its size.
■Tweeter grill that leads to well-balanced sound
Adopts a tweeter grill that spreads sound in highly directional frequency bands. It enhances the acoustic effect and provides well-balanced sound throughout the room.
■Bass reflex duct that produces high-impact bass sounds
The bass reflex duct on the rear side of the speaker is designed to have optimal dimensions for the enclosure. This duct produces impactful bass regardless of the playback device, such as a record player or smartphone.
