In addition, the original Linkwitz approach yields comparably poor sound pressure levels as well. The used chassis, however, massively consumes electric power and must be capable to perform very high displacements. In addition, the Linkwitz Transformer maintains the appreciated flat phase response of closed designs. Applied to a closed enclosure design the so-called Linkwitz Transformer shifts the cutoff frequency to a considerably lower frequency. How to Design a Micro Speaker Enclosure Arrow + CUI Some common methods for creating the front cavity of a speaker enclosure are to use a screen or to create round or slotted holes in a solid plate. Siegfried Linkwitz encountered the aforementioned issue with his well known zero point/pole shifting method. In comparison to a non-augmented design, the phase response of this design still suffers some actually unwanted changes. An alternative is the passively augmented sealed enclosure.

Typical bass chassis for this application are comparably expensive. To achieve deeper bass reproduction sealed enclosures must comprise chassis with high dynamic mass, high compliance, large linear displacement and a strong and heavy magnet. Due to this delay, vented designs suffer from worse phase response compared with sealed enclosures. However, the commonly utilized resonator ports cause other issues, such as flowing noise and delay differences between driver and port. One approach to overcome this shortcoming is the well-known vented enclosure. Either he achieves a small volume enclosure or he achieves a low cutoff frequency. Loudspeaker enclosures for low frequency reproduction face the developer with a goal conflict.
