Mid-woofers from Deaf Bonce: Technical highlights and purchase incentives

If you're looking to buy the Deaf Bonce AP-M67AC 6.5 woofer online at a great price, Masori.de not only offers a lowest price guarantee, but also a comprehensive selection of impressive technical features. With a frequency response of 100 to 15,000 Hz, a maximum power handling of 600 watts, and a sound pressure level (SPL) of 101.70 dB, this speaker promises exceptionally clear reproduction even at high volumes. The innovative ribbed and star-shaped paper cone structure not only increases rigidity but also supports the powerful 1.75-inch voice coil, which enables up to 300 watts RMS power. Your ideal companion for powerful sound!

Properties of the 6.5-inch paper membrane structure

The engineered design of the diaphragm is based on a novel ribbed and star-shaped paper structure. This design solution significantly improves the diaphragm's rigidity, resulting in reduced distortion at high sound levels. It also allows the diaphragm to optimally adapt to the increased magnetic force of the ferrite core. Compared to conventional paper diaphragms, this structure offers significantly better control and precision in the sound stage. An even stiffer diaphragm structure could further improve dynamics at extreme volumes, but at the expense of sensitivity at lower volumes.

Frequency response of the Deaf Bonce AP-M67AC

The frequency response of 100 to 15,000 Hz ensures broad coverage, encompassing both low-mid and high frequencies. This range makes this woofer particularly versatile and allows for integration into a wide variety of car hi-fi systems. An extended frequency response could allow for even finer reproduction of very high frequencies, while a more restricted range would limit its versatility. This wide range allows for seamless combination with subwoofers and tweeters in a multi-way system.

Ferrite magnet and its acoustic advantages

The AP-M67AC's powerful ferrite magnet provides a pronounced magnetic force that further maximizes the efficiency of the woofer. Compared to smaller or weaker magnets, a ferrite magnet offers greater efficiency and thus better sound conversion. A lower magnetic flux would reduce the speaker's energy efficiency, potentially resulting in weaker sound. The aforementioned ribbed paper cone works synergistically with this magnet to create impressively clear sound reproduction.

Voice coil for precise performance: 1.75-inch construction

With a diameter of 1.75 inches, the voice coil in the Deaf Bonce AP-M67AC is extremely robust and is made of CCAW, a copper-wound aluminum wire. This allows this woofer to deliver an RMS power output of 300 watts. A smaller voice coil could potentially increase power dissipation, while a larger one could make the design more complex and heavier. Choosing this size provides an optimal balance between performance and compactness, expanding the application range in various vehicles.

Impedance and its role in the sound

The speaker's impedance is 4 ohms. A lower value would increase current flow, which could result in higher output power, but at the expense of controllability. A higher value would result in reduced power, but amplifier stability could improve. 4 ohms is a common value and allows for diverse system compatibility and efficient use of common amplifiers designed for 4-ohm speaker systems.

Technical data: Resonance frequency and quality factors

The resonant frequency (Fs) of this woofer is 110 Hz. This frequency is particularly evident in its ability to reproduce midrange tones with greater clarity and definition, making it ideal for use in two- or three-way systems. The overall quality factor (Qts) of 0.32 indicates high audio reproduction quality and allows for flexible adaptation in open or closed enclosure styles. A higher Qts could improve subwoofer applications but would be less suitable for a wide frequency range.

Efficient sound pressure level: 101.70 dB SPL

With a sound pressure level of 101.70 dB, this mid-woofer from Deaf Bonce demonstrates exceptionally high efficiency. This characteristic indicates that immense volume can be achieved even without additional amplification. An even higher SPL value might require less flexible positioning, while a lower one might make the speaker unsuitable for large rooms.

Elegant design: cast aluminum frame

The stylish cast aluminum frame not only offers an aesthetically pleasing appearance, but also contributes to robustness and vibration dampening. This type of frame ensures that the speaker's structure remains stable even under heavy loads. A less stable frame material could lead to increased mechanical vibrations, which could negatively impact the sound.

Optimal vase volume of 4.50 liters

The equivalent volume (VaS) is 4.50 liters, which influences optimization for enclosure systems. A lower VaS may favor use in more compact enclosures, while a larger volume increases space requirements but could produce a richer sound profile. This specification aids in the design and development of specially adapted loudspeaker enclosures that further optimize the sound.
