Why Choose the Double Gem
The Double Gem was conceived due to demand for a subwoofer that can fit in limited floor space, we have been told many times by customers that they would love the performance of the larger subwoofers in our range but only had a gap to fit either the Gemini or the XLS200. Whilst listening to subwoofer's in our test room prior to dispatch we are constantly reminded how good two of the Gemini subwoofer's sound. With this in mind it made sense to offer a Double Gemini in as slim a package as possible....the Double Gem was born

B.K. Electronics have been manufacturing subwoofer's for over 20 years making us one of the most experienced subwoofer manufacturers in the world today. Thanks to our extensive range of subwoofer's, whether using the low level input to add the all important LFE to today's blockbusters or to enhance or underpin the performance of a 2 channel music system thanks to BK's Hi Level input, we really have got all basses covered.

B.K. Electronics are pleased to announce their newest subwoofer the stunning Double Gem. Boasting a 300W RMS (600W peak) amplifier coupled to a 2 x 10" " drive units in a sealed enclosure to produce a deep, musical and dynamic subwoofer that can not only shake the room when required but can be subtle and refined, making the Double Gemthe ideal subwoofer for both Hi-Fi and movies.

The Double Gem comes fitted with high and low level inputs which have individual volume controls, a frequency adjustment that can be by-passed on the low level input for LFE use and a continuous 0 to 180 deg phase control. All these features make the Double Gemextremely flexible making it easy to integrate into any Hi-Fi system, home cinema system or even both at the same time.

Not only does the Double Gem have class leading control and connectivity it also comes supplied with an Auto On /Off feature, that switches the subwoofer into standby after 10 minutes of inactivity and instantly switches back on again when it senses a signal on any of its inputs. If you do not like the Auto-On / Off feature then this can be de-activated by toggle switch so that the subwoofer remains switched on until turned off by the main power switch
