For a lively mid-sized pub, active speakers are often a great choice. They're convenient since you don't need separate amplifiers, which can simplify your setup and save space. Look for active speakers with built-in EQ controls, so you can adjust the sound to cut through the ambient noise effectively. Brands like QSC and JBL offer reliable options known for their durability and sound quality.
When it comes to inputs, most active speakers have multiple options, including XLR and TRS, which are perfect for connecting mixers and mics. For additional connectivity and control, consider a digital mixer that allows you to manage everything from one place. Also, look for speakers with a good SPL (Sound Pressure Level) to handle higher volumes without distortion, which is crucial in a bustling environment.
In terms of setup, placing the speakers on stands can help project sound better throughout the space. Additionally, it's beneficial to have one or two subwoofers if you want to enhance the low end, ensuring the sound is full and balanced even when it gets busy.
