The Mackie CR8-XBT is a pair of Creative Reference Series 8" multimedia monitors offering an affordable solution for powerful audio playback in home studios, production rooms, and gaming setups. With 160W of amplification driving 8" woofers and 0.75" tweeters, the CR8-XBT monitors deliver even more volume and bass than the smaller CR5-XBT. The pair consists of one passive speaker and one powered speaker that connect with an included speaker cable. Each monitor incorporates a custom-tuned rear port to smoothly extend the low end and a specially designed waveguide for clarity and proper dispersion of high frequencies. With plenty of I/O provided, the CR8-XBT can accept either a wired connection from your audio interface or computer soundcard or a wireless stream via Bluetooth from your mobile device.
