The SRX818SP from JBL is an 18" subwoofer system featuring controllable DSP, ergonomically designed handles, and DriveCore technology to ensure that its 3" voice coils can deliver a 1000W peak power rating. It offers a frequency range of 29 to 150 Hz and Class D amplification. The SRX818SP also provides HiQnet network integration, which allows you to automate the control interface via many compatible apps. Wired control can be achieved through Ethercon connections. Many localized controls are easily tweaked via the back-panel LCD screen, allowing you to access DSP presets without connection to networks. 

The system accepts inputs from both XLR and 1/4" connection points, and outputs to male balanced XLR jacks. LED indicators for Power, Link, and Data notify you as to the unit's present usage, making it clear whether or not the SRX818SP is on, linked to other speakers via the network, or sending/receiving information to/from other points of access. This subwoofer system can be used for various purposes, including in live performance, mobile and fixed DJ systems, sound system rentals and tours, and permanent installations.

Q: 3. Would two of these JBL SRX815P 15" Two-Way Bass Reflex Self Powered System (tops), together with two of these JBL SRX818SP (sub-woofers) suffice for a DJ event (EDM or Hip Hop) with 50 people IN AN OPEN SPACE? Or double it up? Also, how would I connect the tops to the subs? (Model number?) Also, any competitor model which you could recommend instead of the JBLs?

A: Although speculative when estimating how well a speaker will fill an open space, each JBL SRX815P 15" Two-Way Bass Reflex Self Powered System offers 2000W of power on its own, which seems significant for a small crowd of 50 people. When paired with the JBL SRX818SP 18" Self-Powered Subwoofer System, source audio would feed the subwoofer, and the subwoofer would feed signal to the tops with standard 3-pin XLR audio cable.
