As one of the best floor standing speakers on the market, the Divine Alpha is an absolute jewel in every way. The ceramic midrange driver we use originates from the German high-end manufacturer Accuton and is one of the best worldwide. In combination with the ceramic dome tweeter also made by Accuton and the two SEAS Aluminum bass drivers, its sound reproduction is a perfect balance of harmony, smoothness and accuracy. Due to the unbelievable performance of the drivers, the Alpha can play at inconceivably high sound pressure levels while still maintaining high precision and control. Convince yourself by listening to this masterpiece of loudspeaker construction!
Drivers
The Divine Alpha is built around the fantastic C173-T6-090 midrange driver, one of the best midrange drivers from the German high-end driver manufacturer Accuton. It is usually used in only the best and most expensive high-end speakers in the world. The tweeter is also made by Accuton and is one of the best ceramic dome tweeters available today. These two high-end drivers are supported by two excellent 10” customized aluminum bass drivers from SEAS.
Sound Tuning
The highly-complicated frequency filter network provides the ability to adjust the level of the tweeter and the two woofers and in this way, adapts the entire speaker not only to the listening space, but also to personal preference. Further adjustments can be made by using the two supplied plugs for the bass reflex tubes that can be used to close the housing of the Divine Alpha for even better precision. Divine Alpha can also be adapted into an active speaker. This is done by by-passing the passive crossover and using it as a three-way active speaker system.
Cabinet
The housing of the Divine Alpha consists of several layers of MDF with a thickness of up to 90mm so it achieves a highly rigid structure. Additional support is achieved with the use of convex sidewalls to keep resonances inside the cabinet to a minimum. Furthermore, the effective damping material that is used helps the Alpha to achieve its unique superiority. The housing consists of several chambers to provide the respective drivers with optimum working conditions. Divine Alpha includes four very stable chrome plated aluminum spikes that are adjustable to enable the finetuning of the angle of the speaker to optimize the sound according to the listening position. The curved sides are designed to reduce the formation of internal standing waves that can occur in traditional speakers having a rectangular design.
Surface
Divine Alpha is covered in a perfectly polished piano black lacquer. This multilayered paint is a real work of art and emphasizes the perfect proportions of this outstanding speaker. The convex form of the Alpha beautifully reflects its surroundings.
Terminal
The connection terminal of the Divine Alpha includes chrome tri-wiring connectors to provide a perfect fit for the speaker wire. Butterfly nuts made of brass ensure a perfect signal transmission. The internal cables are from Supra in Sweden, produced for XTZ and consist of 99.99% pure copper.
Front Cover
All drivers of the Divine Alpha are protected by metal grills to avoid potential damage. The covers for the tweeter, the midrange driver and the bass drivers are permanently installed and optimally matched to the drivers.
Tweeter
We have chosen an ultra-fast ceramic tweeter (Cell C25-6-158), made for reproducing crystal clear sound, even at high sound pressure levels without any distortion. The tweeter is produced by the German company Accuton, and is an absolute reference class unit. It is shielded, with an internally damped cavity and a ventilated voice coil. The tweeter offers an extremely flat frequency response and a low resonance frequency.
Midrange Driver
XTZ Divine Alpha uses the Accuton C173-T6-090, one of the best (if not the best) midrange drivers in the world and can only be found in extremely high end loudspeakers. The C173-T6-090 is a ceramic driver with a light cone, equipped with a neodymium magnet. The driver is extremely stiff and at the same time light, which contributes to its high sensitivity. The two black dots are far from a design gimmick. Accuton (Thiel & Partner) has put them there for a reason as they suppress a resonance from the cone. The Accuton driver offers the highest quality and highest resolution; this is the reason that this driver is used in the best speakers in the world.
Woofer Driver
For the woofers, we selected two aluminum 10” drivers from the Norwegian company SEAS which has been producing drivers for the last 60 years. These woofers were further developed in partnership with SEAS and this led to a perfectly customized version which is optimized exactly for the Divine Alpha’s cabinet. We have added a heavy copper ring above the T-shaped pole piece and a solid aluminum chrome plated phase plug to reduce the non-linear and modulation distortion and increase the overload margin. The woofer has a cone made from pure aluminum. The molded metal basket is a “high flow” type that is acoustically transparent that reproduces sound with great precision due to how it is formed in the molding process. This ensures that the basket is very stable and that it efficiently reduces resonances. The basket is completely non-magnetic, which contributes to the higher efficiency of the driver. A strong magnet combined with the light cone yields high efficiency and a good transient response. The gold-plated terminal reduces contact resistance and serves as an anti-corrosion coating. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonances.
High Quality crossover
When XTZ produced the Divine Alpha a great deal of effort was put into designing the crossover filter. All passive components are of the highest possible quality to minimize any influence on the signal. We use an optimal selection of air wound coils (with low internal resistance) and coils with steel cores (these accept a high level of magnetic saturation), MKP capacitors and MOX resistors. The Divine crossover is basically a 3rd order filter for woofer and 4th order for the tweeter. The exceptionally good Accuton midrange driver led us to this solution. With its chosen roll-off, it contributes to both the low distortion and high power handling characteristics of the speaker.
Sound Tuning
The Divine Alpha is equipped with XTZ’s Room Tuning concept which with simple settings can alter the speaker’s sound character. Inserting the two bass plugs into the vented holes opens up different options that will create three different bass variations in the sound. The terminal is equipped with switches that allow adjustment of the tweeter and the bass in two ways or levels.
Alpha is also prepared to be actively driven. You can by-pass the passive crossover and build up to a 3-way active speaker system.
