The starting point for the design of the AW-3 Aluminum model was its small size, but at the same time high-quality playback characteristics.
The bass reproduction capacity was wanted to be large enough for the speaker to work without additional bass, especially in smaller spaces. Back then, the natural choice for bass midrange size was 4 inches. Seas' selections include the high-quality aluminum cone model L12RCY / P, which operates in a small housing when playback reaches less than 60 Hz. As a long-lasting element, it also produces quite high sound pressures when required, taking into account the size of the element. In addition, the playback characteristics in the midrange range are also excellent.
A model 27 / TBCD / BG-DXT with a gentle guide was chosen as the treble from the Seas collection, the radiation pattern of which was easy to implant to work with the 4-inch element.
The case of the AW-3 model is a TransFlex case developed by Hifitalo. In a small speaker, the benefits of the TransFlex case come to the fore, especially in the bass range. TransFlex housing
reduces the movement deviation of the bass element by loading the element clearly more efficiently than, for example, a standard reflex housing does. This small four-inch element provides surprisingly good and clean bass reproduction, while maintaining the linearity of the bass reproduction even at higher intensities.
The distribution filter is simple in basic connection. The circuit next to the bass removes the resonance peak of the aluminum cone, otherwise no additional correction circuits are needed in the filter. In the treble filter, it is possible to influence the treble level by changing the value of the resistor R1.
The AW-3 Alumium is a speaker that is amazing. The playback is balanced and pleasant. AW-3 Aluminum sounds clearly larger in size. It works in a small room for listening to music without a subwoofer. In the larger mode, the subwoofer brings more power to low bass playback. The stereo image is accurate, but at the same time wide, as long as you remember that the listening distance cannot be very large due to the small directivity of the elements. Due to the versatility of the small size, as well as the excellent sound, the speaker is suitable for a wide range of uses, from listening to music, movies or even as a computer monitor for those who appreciate high-quality sound.

Note!
If you do not want to make the case yourself, you can order it ready-made. The pattern wood makes speaker cases from MDF or glulam according to the customer's wishes. The selection includes almost all the building kits sold by Hifitalo, and if necessary, you can also submit the speaker drawings yourself. See the link below for more information and prices.
