Speaker Comparison

When it comes to filling your personal space with lush, nuanced sound, few contenders rise with the prominence of the Audioengine A2+ Wireless Bluetooth Speakers and the MartinLogan Motion 15i Bookshelf Speakers. Both sets boast attributes that appeal to distinct facets of the audiophile community and even the casual listener. But how do they stack up against each other?

In contrast, the MartinLogan Motion 15i embodies the high-fidelity listening experience with its signature Folded Motion tweeter.

The Motion 15i's dedicated woofer ensures that the midrange remains uncolored, while also delivering a tight and responsive bass. It is, without question, a speaker that caters to the audiophile who demands a truthful representation of the music.

Design and Build

The Audioengine A2+ champions a minimalist design, with clean lines and a size that fits unobtrusively on most desks and bookshelves.

The MartinLogan Motion 15i, meanwhile, is a statement piece that carries a certain gravitas in its presentation.
