JBL JRX 115 Trapezoidal 15” Speaker System (Single) Reviews


Such clarity, such punch

I bought these speakers a while back now with the Yamaha EMX212S powered mixer, which is a little under the minimum rms for the speakers.

THESE SPEAKERS POUND!! seriously, if you are looking for CRISP clean highs, CLEAR fruity mids and HARD hitting punchy lows this speaker is what you want. Amazing throw capibility, it can be heard clearly everywhere in a venue.

I am currently only powering these speakers (pair) with 200Wrms each, which is 50W under the minimum recomended amplifier power. Yet still on a test i did one day to see how loud the setup could go, the bass vibrated the bolts on the door open, my vision went blurry and the lights all dimmed!!!!

The ported enclosure is tuned to around 32-35hz which is perfect for hard hitting bass, from the deep lows to the punchy higher end kicks.

The carpeted finish gives a lovely feel and look, with stong handles for lifting.

On the rear there are jack connections for parallel wiring etc.

And finally, its JBL!!

and i cant wait to get an amp to PROPERLY power these beasts...

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.

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.).

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.
