GAE’s uncompromising bass horn construction is called ETAMAX. It allows the reproduction of low frequencies with a minimum distortion and high sound pressure levels. State-of-the-art simulation programs and elaborated enclosures are the basis for the optimized horn contour and its folding. By the help of the backwards enclosure-chamber the parameters of the 18’’ driver are exactly adjusted to the acoustic situation of the pressure chamber and the sound conduction. The acoustical resistance thus obtained damps the driver optimally and produces a frequency specter largely expanded to the low specter without bothersome resonances.
By stacking several ETAMAXs this effect is redoubled, leading to a major horn construction unsurpassed in sound and power. ETAMAX reproduces low frequencies exactly, powerfully and with noticeable directivity. It is especially apt to back up far-ranging sound systems (as for instance GAE’s WaveLine) in the bass range.
The particular economy of this bass horn construction becomes apparent with big sound engineering challenges as the usual number of high power amplifiers can be drastically reduced. The operation of an "ideal" 30 Hz horn (6 pieces of ETAMAX) with a total impedance of 2x 2.7 ohms and an appropriate 2 channel amplifier is highly economic. As the complex parts of the impedance virtually vanish into thin air such an application offers a perfect resistance to the amplifier.
The toll taken by these special ETAMAX construction-characteristics rests with its dimensions, but the ingenious positioning of the 10 handholds simplifies the handling. Aluminum fixing bolts in the top and the bottom of the enclosure close to its back guarantee a save stacking. The enclosure is sumptuously built of high quality multi-layered birch-ply and sealed with a black structure varnish by standard. Different RAL colours are available. The loudspeaker’s baffle and it’s components are protected by a solid metal front grill which is backed with an opaque acoustic foam.
