The product price includes a one year warranty and 30 day money back guarantee.

However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

StudioLive's Active Integration 32-bit 96 kHz DSP gives the groundbreaking new 18sAI subwoofers studio-monitor accuracy and delivers a wireless and wired control of all setup, tuning and monitoring functions using the free SL Room Control software for Mac, Windows & iPad.

The StudioLive 18sAI delivers low frequencies with plenty of muscle thanks to the 1000 Watt bridged Class D power amplifier.

Connections are straightforward with stereo line inputs (XLR and 1/4" combo) and full range, switchable stereo/summed-mono line outputs (XLR).

The lightweight plywood enclosure includes ergonomic side handles, an integrated pole insert and interlocking stacking provisions for use with a full-range system such as those in the StudioLive AI Series.

What makes the StudioLive 18sAI really special is the amazing accuracy and control features courtesy of the PreSonus Active Integration Technology.

Active Integration technology realises the dream of products that sense each other, interact and work together via both wired and wireless communication, featuring 32-bit floating point DSPs and seamlessly integrated software.

Active Integration incorporates all of this into a specialised custom chip that can handle not only the specialised algorithms for tuning the system to near-perfection, but also providing extensive remote control over system performance, the variable low-pass filter and more.

Wirelessly control output level, user-adjustable contours and more using the 32-bit floating point DSP for the variable crossover, dynamic limiting and excursion limiting.

The included USB Wi-Fi LAN adapter enables wireless networking, with the master control centre residing in the SL Control Room: a feature-rich, easy to use system-configuration software application for Mac, Windows and iPad that offers individual or group control of all StudioLive AI-Series speakers on the network. SL Room Control gives you control over most onboard controls and lets you monitor key performance indicators.
