Technical description jamo sub 250, 300, 550, 650
General description with this dedicated subwoofer line up from jamo we wanted to achieve several goals. We wanted a subwoofer line up with the best ever performance per $ and we wanted it to be able to match a variety of different speaker solutions on the market, including jamo of course. Making a d...
Because of the flat frequency response all the way to 150hz, sub 250 is the ideal match for small satellite speakers, since it allows you to integrate it seamlessly without missing the important middle bass area. Many subwoofers fall of very drastically above 100hz (or some even under, see picture 2...
Since sub 550 reaches very low, it features a boundary gain compensation switch, which further helps to keep a flat frequency response, as bgc compensates for the room influence at low frequencies. The level control is placed on the front of the subwoofer, elegantly integrated in the design, with a ...
Electronics the important things on subwoofer amplifiers are the ability to deliver high power – especially peak burst are important to reproduce e.G. An explosion or a bass drum with full fidelity. This has to be done with a minimum of distortion and a very tight control of the woofer. Due to the n...
Most of today’s subwoofers have an auto on/standby feature whereby the subwoofer switches itself on if it senses a signal and switches in standby mode again a certain time after it has last sensed a signal. However, in movies (or typically classical music) with relatively quiet passages the subwoofe...
In/outputs all the subwoofers features speaker level inputs if there is lack of a line level/lfe level output on the amplifier/receiver. All subwoofers also have both left and right line level input in case of stereo sources and a loop through capability, i.E case the signal needs to be routed throu...
In normal setup, the port is radiating towards the rear wall, giving an even higher efficiency at very low frequencies..
