Acoustic Research AWSBT4BK Portable Wireless Speaker with Bluetooth
This wireless speaker from Acoustic Research offers solid, affordable performance. Although the AWSBT4BK cannot match the versatility or performance of higher-priced models, this portable speaker can be used both indoors and outdoors, using eight AA batteries as well as the AC adapter. The AWSBT4BK uses Bluetooth streaming to play music from Apple and Android devices and has an AUX input. Its two-way design uses a three-inch woofer and 1.5-inch tweeter, delivering reasonably good sound output.
This speaker is not actually rated to be specifically used outdoors, as it is not weather-resistant. However, its portable design makes it well suited for small backyard events. The AWSBT4BK is less effective for very large space as it simply doesn't have the necessary volume output. If you don't need a permanent outdoor setup and would prefer a simple, affordable option, the Acoustic Research AWSBT4BK is a good choice.
