We have a small quantity of these wonderful speakers available. They’re brand new. Once they’re gone, they’re gone!
Typically known as ‘Earth Mover 2’ (EM2) speakers in the UK, these powerful units have taken on a somewhat legendary status with the railway modelling community in recent years.
There is nothing quite like them for getting that near authentic howl of a Deltic, the growl of a Class 37 or the whine of a Valenta turbo as your HST pulls away from the station. They shout quality!
Their bass response is unmatched by other similarly-size products, which is achieved to a large extent by their special sealed design, with a passive radiator working in tandem with the driver.
YouTube is awash with videos of fabulous LokSound DCC sound conversions featuring these products and no DCC sound layout is complete without at least one loco fitted with an EM2 speaker!
Note: these speakers do not come with a connector/flying lead. The on board connector is a Micro JST 1.25mm Pitch male plug.
The speakers pack a punch, but are slightly larger than many of the other ‘mega bass’ or similar alternatives. A small socket is provided on the side of the speaker for hooking up or, as is more common, wires can be soldered directly to the contacts (see diagram below).
While they can be dropped into some Hornby and Lima models with relative ease (particularly with many Hornby Railroad and Hornby/Lima ringfield), most Bachmann, Heljan, Dapol and newer Hornby models will require varying degrees of adaptation.
With an impedance of 4 Ohms, these speakers can be used directly with all Loksound 4 and 5 decoders and some Zimo decoders (please check Zimo’s manuals and website for compatibility).
If you wish to use them with other decoder types (incl. Hornby TTS decoders), you must wire another 4 Ohm speaker in series (bringing the total impedance up to 8 Ohms), otherwise you risk damaging or destroying the amplifier on the chip.
These speakers are not compatible with LokSound 3.5 or earlier decoders.
