Aperion Intimus 4B

The Aperion Intimus 4B are small 2-way bookshelf speakers at the low-end of the Aperion lineup. They feature a 4" woven-fiberglass mid-range woofer and 1" silk-dome tweeter. They are sold individually for $130 each with the step-up models Aperion 5B ($225 each) and Aperion 6B ($345 each) featuring larger mid-range woofers (5.25" and 6.5" respectively) and, thus deeper bass response. The frequency response form the 4Bs only go as low as 120 Hz (+/- 3dB), but not much more can be expected from a speaker of this size; it only measures 8.75" H x 5.33" W x 5.5" D. They are made from the same High Density Fiberboard (HDF) as the other speakers in the Intimus lineup and are available in glossy black and medium cherry. The 4B bookshelves can be paired with the Aperion Intimus 4C center channel ($160), or can be used as a rear-surround in a more powerful setup.
