Signature Sound and Performance
The smooth and extended frequency response of these Dayton Audio speaker drivers ensures that the entire audible spectrum is accurately reproduced, from the lowest bass notes to the highest treble frequencies. This well-balanced frequency response delivers a natural and immersive listening experience, allowing you to hear every detail and nuance in your favorite music or movies.
Meticulous Attention to Detail
The speaker drivers' design, materials, and meticulous engineering work in harmony to minimize distortion, ensuring that the sound remains clean and clear even at high volumes. By achieving low distortion, these speaker drivers provide an accurate representation of the original audio signal, allowing audiophiles to enjoy a true-to-life listening experience with exceptional clarity and precision. The Signature Series speaker drivers used rigorous Klippel testing throughout the design process, a state-of-the-art analysis method to provide optimal performance, consistency, and reliability by precisely measuring and optimizing the drivers' magnetic and mechanical properties.
Featuring the innovative use of aluminum shorting sleeves, our speakers deliver unmatched audio performance. These Faraday rings, expertly situated around the driver's pole piece, not only stabilize the magnetic field but also significantly reduce inductive distortion. The result? Consistent, high-quality sound in every note. Thanks to aluminum's superior conductivity, every audio signal is transmitted efficiently and without distortion.
Indexed Cone and Surround Junction
Diffraction caused by the abrupt edge of the surround is minimized by the use of an indexed junction. This design feature helps create a smooth transition between the cone and surround, resulting in improved frequency response while improving the rigidity of the cone further resulting in less cone distortion at high excursion.
Vented Polyimide Former with CCA Voice Coil Wire and Elevated Spider Suspension
The polyimide voice coil formers provide excellent mechanical damping and a smoother frequency response, and the copper-clad aluminum (CCA) wire reduces moving mass further enhancing the overall sound quality and increasing the efficiency of the speaker driver. An elevated spider and vented former increases airflow to the coils to keep the assembly running cool during long periods of use.
Concave Black Anodized Aluminum Cone
The aluminum construction of the cone is lightweight, rigid, and helps reduce distortion, contributing to a more accurate sound reproduction. The anodization process is optimized to contribute to the dampening of the cone and provides high aesthetic value to any speaker design.
Open Aluminum Cast Frame and CNC'd Stainless-Steel Badging
The aluminum cast frame keeps movement isolated to the diaphragm, increasing low frequency performance and providing additional thermal dissipation. Stainless-steel badging completes the sleek aesthetic of the Signature Series drivers providing a timeless visual appeal for every speaker designer.

Apart 120 Speaker Kit Es funktioniert immer wieder: Give a small box a little more level in the upper bass range and it willimmer voll und komplett klingen. That worked with our last Cheap Trick and thatfunktioniert noch viel besser bei der Apart 120. Okay, if you take it very precisely, you canSubstance in the lowest layers is missing, but when you just listen to music, the mini floorstander convinces.with power and dynamics in the bass, clean vocal reproduction and clear and precise highs that theFolienhochtöner dynamically and finely resolved reproduces. And yes, the small box can also handle volume.and then it also pushes a lot of air – you can and should let the small Dayton bass worklet. This does not just end in a short "Oh, the little one can be really loud" effect,but also works permanently, as the clean and dynamic sound is thoroughly suitable for long-term use.Good box! Thomas Schmidt / Sound & Tone 6/2023 Small Box, Big Impact! The new Signature Chassis from Dayton Audio are quite attractive and affordable. Astable yet delicate cast basket with 6 mounting holes offers more than enough support. Theinverse aluminum dome membrane is extremely robust and black anodized. The Apart 120 has proven itself as a small floor-standing and sideboard speaker. With its slim design andslightly angled positioning convinced them the most in our rooms. Initially, it was alonger and deeper tuned line planned, but for a bit more level stability, aAbstimmung omitted at 45Hz. This works absolutely satisfactorily, as we find. A -3dB-Point at 70Hz, which extends to 60Hz depending on room acoustics, ensures tight bass without excessivewummernd zu wirken. The frequency response shows a gentle decrease over the entire range, with abovefrom 12kHz there is still a slight increase to note, which, however, does not make a noticeable difference in sound.The crossover frequency is at 2000Hz with an 18dB slope, an impedance linearization, andVoltage divider before the tweeter, which works wonderfully with resistance values in a 12-series +1dB/-1dBcan be regulated.

When attaching the mounting frame for the tweeter, care should be taken becausethe frame is very delicate and can bend if too much screwing pressure is applied. The soldering of theHochtöners should be avoided, as excessive heat can damage the foil. With the SIG120-4, this isSoldering, on the other hand, is harmless as it is the safest connection.
