The Borderland MK IV is their most popular loudspeaker. It combines the unique carbon fibre DDD driver with a downward firing 12–inch woofer and a sophisticated new crossover network. Housed in an extremely rigid octagonal cabinet, it sets standards for stereo imaging, transparency and musicality.

The DDD driver has two key distinguishing features:

1. It is omnidirectional, radiating the sound evenly around it.

2. It has an exceptionally wide operating range. It covers the range from 190Hz up to 24kHz – almost 7 octaves.

The bass driver is located at the bottom of the cabinet and works in a “sealed” enclosure. This enclosure is linked via a small opening to a smaller cavity located at the top of the cabinet. This cavity acts as a Helmholtz Resonator and is tuned to the resonant frequency of the main bass enclosure and ensures a smoother bass response.

Adjustable High Frequency Output

Jumpers on the rear panel allow the high frequency output level to be adjusted in 4 steps: -2dB, flat, +2dB and +4dB. This allows the user to easily compensate for the variations in the absorption of high frequencies that occur due to different types of furnishings and room constructions.

All products on Hi-Fi Disposals are sold with a 12-month warranty covering parts and labour.
