To round out the sound of small and medium-sized 2-way systems, use our 30 cm subwoofer sphere. Small and unobtrusive, it blends harmoniously into any room. No more sharp edges, just a perfectly rounded design! The new grille is significantly more stable than the perforated metal mesh and can be carefully removed.
As early as 1951, Harry F. Olsen determined that spherical enclosures least affected the frequency response of the loudspeaker: Link to the document
The sphere is superior to all other loudspeaker cabinet shapes due to its static stability and acoustic neutrality. Stability is further enhanced by six internal braces. Only the speaker diaphragm of our built-in D-165 subwoofer chassis It is designed to vibrate. The 16 cm aluminum diaphragm generates high alternating pressure without "bending" itself or the housing.
All RECKHORN subwoofer amplifiers provide powerful drive. With the A-409 Subwoofer Amplifier Even more deep bass can be extracted electronically. However, the low-bass roll-off can only be compensated for with this closed-back design using other equalizers. It is particularly economical. A-2.1 stereo amplifier With its variable electronic crossover and 3-channel power for stereo satellites plus a mono subwoofer, this amplifier is suitable for other subwoofer amplifiers with an adjustable low-pass filter. If you have an AV receiver with a built-in crossover for the subwoofer range, you can also use a standard amplifier.
The cable connection is duplicated to allow for connection to a second subwoofer. For amplifier impedances of 4-8 ohms, connect in series (8 ohms) and in parallel (2 ohms) for amplifiers with a 2-ohm impedance. Our subwoofer amplifiers, including the A-2.1 subwoofer channel, are 2-ohm compatible.
