Abstract
Various implementations include loudspeakers. In some particular cases, a loudspeaker includes: a high frequency (HF) driver; a low frequency (LF) driver coaxially arranged with the HF driver; and a waveguide overlying a sound radiating surface of the LF driver, the waveguide having a hole pattern such that a sound radiation pattern of the LF driver matches a sound radiation pattern of the HF driver at a reference location.
