Presonus StudioLive 18sAI Active Subwoofer

Presonus have been making a name for themselves marrying innovative DSP with quality analogue products. Their new range of PA gear brings studio quality to the stage, not relying purely on raw power it's the clarity of the StudioLive speaker range which sets it apart.

How low can you get?

With the StudioLive 18sAI, you can get pretty darned low! And it delivers those low frequencies with plenty of muscle, thanks to its 1,000 watt (bridged), Class D power amplifier. Connections are straightforward, with stereo line inputs (XLR/¼-inch 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. Options include a mountable Sub Dolly and pull-tested Sub Pole to mount a full-range system atop the 18sAI. These features are important but what makes the StudioLive 18sAI special is its amazing accuracy and control features—the result of PreSonus Active Integration technology.

You’re in control—here, there, and everywhere

Every Active Integration product—including StudioLive AI-series speakers—includes both wired and wireless communications. The included USB Wi-Fi LAN adapter enables wireless networking. Wired communications are provided via an installed option card with an Ethercon port that connects to your Ethernet-based LAN network. The master control center resides in SL Room Control, a 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.

The future is Active Integration

Products that sense each other, interact and work together via wireless and wired communication, feature 32-bit floating-point DSP and seamlessly integrated software, and run on CPUs far more powerful than competitors’ current audio products—PreSonus has realized this dream with its new Active Integration technology. Active Integration incorporates communications, wireless networking, and huge amounts of DSP into a specialized, custom chip. Essentially, we’ve put a computer into these speakers, with enough processing power to handle not only the specialized algorithms for tuning the system to near-perfection but also providing extensive remote control over system performance, the variable low-pass filter, and much more. As with the full-range StudioLive AI-series systems, the StudioLive 18sAI offers the benefits of Active Integration, including remote control—including wireless control—over output level, user-adjustable contours, and more and uses 32-bit floating point DSP for the variable crossover, dynamic limiting, and excursion limiting.

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
