In this roundup we look at a wide range of self-powered loudspeaker systems. Some of the products are aimed at applications where a temporary setup for events, meeting, and related activities is needed. (These are often referred to as speakers-on-a-stick). Others are installation oriented. Many can be used for either purpose, but be sure to avoid using portable systems for permanent installs. Each product is paired with an appropriate powered subwoofer to make it easy for you to look at complete full range systems from each company.
As you will see in this listing, an ever increasing number of manufacturers are now offering loudspeaker systems with self-contained/on-board amplification and DSP-based crossovers, correction tools such as Eq, delay and filtering.
The primary advantages of this approach is that the amplification and signal processing can be precisely matched to the specific loudspeaker components used in the products.
This is not always feasible with external amplification and signal processing, although many (but certainly not all) manufacturers offer model specific amplification and signal processing for their passive systems.
The other advantage this approach offers is that the often heavy, long runs of loudspeaker cabling from remote amplifiers to the speakers are no longer required. You do have to provide
