Citronic LOSUB-15 Low Profile Passive Subwoofer — 15", 600W RMS, 8 Ohm

Citronic  |  SKU: 178.136

Serious Low-End Power From A Cabinet That Doesn't Get In The Way

Most subwoofers capable of genuine 600W handling come in cabinets deep enough to become a physical obstacle at ground level — something to trip over, something that won't fit under a stage riser or beside furniture in an installed space.

The LOSUB solves that through its cabinet geometry rather than by compromising on power. A downward-angled baffle creates a pressure zone at ground level and ports it forward, meaning the driver doesn't need the large rear air space that conventional sub cabinets require. The result is full 600W RMS handling from an enclosure just 360mm tall — low enough to sit under or alongside furnishings, tuck into narrow install spaces, or simply take up less floor space at a gig without giving up any of the low-end authority a proper subwoofer needs to deliver.

Description

600W Of Genuine Low-End Power From A Cabinet Barely 36cm Tall — Citronic LOSUB-15 Passive Subwoofer

The Citronic LOSUB-15 is a low-profile passive subwoofer built around a 380mm (15") driver, using a semi-directional ported design with a downward-angled baffle that creates a pressure zone at ground level and ports it forward. This geometry allows the driver to operate effectively without the large rear air space a conventional subwoofer cabinet requires, keeping the enclosure's overall height to just 360mm — low enough to sit under staging, alongside furniture, or in narrow install spaces where a taller cabinet wouldn't fit. The MDF enclosure is finished in durable polyurea coating, with routed carry handles and a 35mm pole mount socket for adding a top cabinet above the sub.

Input from a power amplifier is via two Speakon connectors, with a built-in passive filter (120Hz low pass, 12dB/octave) removing unwanted mid and high frequencies before they reach the driver, keeping the LOSUB dedicated purely to low-frequency reproduction. Power handling reaches 600W RMS (1200W maximum) at 8 ohms, with a maximum SPL of 127dB and a frequency response of 40Hz to 2kHz. Whether deployed for space-saving transport and storage, or built into a discreet installed space, the LOSUB-15 delivers a strong sub-frequency response without demanding the floor space a traditional subwoofer cabinet would need.

Really happy with the PC and the service received. Communication was excellent throughout the build process. All delivered in good time and received with plenty of helpful advice, especially from Kieran after delivery to help me set it up.

Will definitely recommend. Many thanks

Ordered guitar strings which arrived in two days, inside package was an offer for a guitar tuner which also arrived in two days. Excellent customer service.

Terence Hamilton

At the offer price this was very good value for money. I have generally found Snark tuners to be very good although with the low tunings I use I often find they can take a little time to give an accurate reading moving from string to string. Otherwise, Great!

Jason Davey
Snark SN1X Clip On Guitar Tuner - Blue

This is my second Snark Tuner, there are various versions, this one is for use at home the other is RF shielded and has rubber protection incase dropped. Both work excellent and are the best clip-on tuners I have used. The service given by Audio Direct was first class, Dave even telephoned me to discuss a query I had not something many online traders would do so overall 10/10

It sounds like it's supposed to sound, easy to shape the tone on each of my electric guitars. Yes, each of the amplugs is a one (or two) trick pony, but they do what they're supposed to well, and they each sound like the amp they emulate.
