The influence of the large voice coil design on sound quality and power handling

The Accuton C220-6-222 is equipped with an outstanding 55 mm titanium voice coil capable of handling 150 watts. The large coil provides the woofer with an excellent linear excursion of +/-6 mm. This enables precise bass reproduction, even at high volumes. The use of titanium as the coil former material guarantees stability and heat resistance. A smaller coil would inevitably limit excursion and thus low-frequency reproduction. A larger coil, on the other hand, could reduce efficiency. This design achieves an optimal balance between precision and performance.

Features and advantages of the neodymium magnet system in the Accuton C220-6-222

The underhung neodymium magnet system, measuring 120 mm in diameter and 49.5 mm in height, significantly reduces distortion. Neodymium is known for its powerful magnetic energy, ideal for minimizing unwanted harmonic distortion. By keeping the voice coil under control, it improves overall sound quality. A smaller magnet system could compromise voice coil control and lead to higher distortion. With a strategically optimized magnet structure, this woofer delivers highly precise sound reproduction.

Thiele-Small parameters of the Accuton C220-6-222 and their meaning

The C220-6-222 boasts Thiele-Small parameters such as a resonance frequency (Fs) of 29.5 Hz and a total quality factor (Qts) of 0.26. This optimization allows for precise design for closed or bass-reflex enclosures. The equivalent volume (Vas) value of 74 liters demonstrates the driver's ability to cover a large acoustic space. Compared to higher Qts values, the value used here delivers tighter and more controlled bass response, while a lower Fs enables deeper bass. These parameters allow designers to meticulously adapt the loudspeaker to individual applications.

Possible uses in different housing configurations and their effects

The Accuton C220-6-222 offers various enclosure recommendations: Sealed enclosures with a volume of 11.5 liters deliver a F-3dB cutoff frequency of 74 Hz and a Q value of 0.71. For extended bass, you could also use a 24-liter enclosure. For bass-reflex enclosures, a volume of 29 liters is recommended, with a passive radiator achieving a low frequency of 23 Hz. A sealed enclosure can deliver a more precise sound characteristic, while a bass-reflex design enhances the bass range. This flexibility makes the speaker suitable for a variety of acoustic requirements.

Mechanical design and its impact on acoustics

The mechanical design of the C220-6-222, with an overall diameter of 220 mm and a height of 112.5 mm, ensures structural stability. The ceramic diaphragm promises razor-sharp sound performance while being resistant to modal resonances. The mechanical Q factor (Qms) is tuned to 5.61, which minimizes energy loss due to friction. Audible stability in low frequencies is ensured, and concert pitch imaging is significantly improved. A different mechanical design could adversely affect the frequency response; in this case, a perfectly coordinated interaction has been achieved.

Precision through special connection options for advanced sound settings

The 6-ohm impedance allows flexibility in amplifier selection and contributes to efficiency. The 7.23-ohm resistance ensures stable current distribution. The BL force factor of 11.7 N/A indicates the speaker's motor strength, which supports the powerful drive of the diaphragm. A lower BL value might reduce the efficiency of this force transfer and thus produce a less precise sound. These specifications combine control with efficiency, resulting in exceptional sound.
