The New and Awesome Monolith Plus -DF + Subwoofer 500W RMS (1000W Peak) 12" Ported Reflex

Introduction:-  We are pleased to announce the introduction of the latest version of the Monolith Plus subwoofer. Working with our speaker manufacturer we have designed what we think is a better more dynamic loudspeaker that will improve the overall performance of the Monolith Plus. We have kept the specification as close as possible to the original loudspeaker so as not to lose the musical qualities but have beefed up the speaker to enhance its home cinema pedigree. One of the major upgrades was to reduce the power compression to the voice coil, the engine room of the subwoofer which now has a 3.5" Diameter voice coil and a larger vented pole piece enabling to easily handle whatever content is thrown at it

The Amplifier:- At the heart of the Monolith Plus is our B.LAT Amplifier, starting it's life in the original REL Studio and Stentor subwoofers this amplifier has been continuously refined and now includes an array of features and controls not found on any other subwoofer in this price range. Controls include volume adjustment for both high and low level inputs, low pass frequency contour 40 to 120Hz and a continuous phase adjustment. With all these functions available to hand the Monolith Plus amplifier will allow the end user varied connection options and ease of fine tuning. This amplifier is built here at our UK factory and is rated at 500W RMS and 1000W RMS peak dynamic.

The Cabinet:- Out of necessity the cabinet has to be large after all we are designing a high SPL and low distortion subwoofer. The cabinet has to be strong, rigid and not colour the sound. So, it's made from 25mm MDF and critically braced. The port has a 100mm internal diameter and is flared both ends to further eliminate port noise.

Drive Unit:- A 300mm / 12" twin magnet drive unit to increase linear excursion, a cast basket for a solid uncoloured projection of sound without ringing and vented pole piece to help reduce power compression.
