99 Series Active & Passive Sub-Woofer for XTZ 99.26 mkII & 93.23 BookShelf Speaker。






99 W10.17P / Flexible High End Passive Subwoofer

(For XTZ 99.26 mk II & XTZ 93.23 BookShelf Speaker.)

99 W10.17P is a very flexible passive subwoofer in an elegant piano finish. You can now have more control of your sound as you are free to select any amplifier for the subwoofer (suitable power is 100 - 400 watts).
A good example of a competent external amplifier is the Sub Amp 1/Sub Amp 1 DSP. An advantage using an external amplifier is that you can connect two subwoofers, thus reducing the problems with nodes/modes in the room.
  • 10" long stroke aluminium driver from SEAS
  • Stable and bar reinforced cabinet with 25 mm MDF
  • Selectable bass reflex- or sealed construction
  • Non parallell walls to minimize standing waves
  • Heavy terminals accepting banana, fork etc
  • 8 layers of piano paint
  • Room Tuning


Technical presentation
The cabinet is built from 25 mm MDF with several internal bars for a robust and rigid construction without resonances. The idea is that the 99W10.17P can be used together with for example 99.26, but of course it can be used with other speakers as well (as a separate bass module). Together, these form a potent 2.2 system.
After evaluating several drivers, the choice fell on the SEAS units. Norwegian SEAS is today a world leading speaker/driver manufacturer. Their drivers can be found in several upper High End speakers. With their 60 years of experience, they possess knowledge that usually puts the competition behind.

The driver has a high flow type solid aluminum cast basket, acoustically transparent. The membrane is extremely rigid, and in combination with the soft rubber suspension the usual edge resonances are effectively eliminated. The magnet is a 3 kg unit. This together with the very powerful magnet, low weight membrane and stable suspension provides both power and precision to the sound.
99W12.17P has got rubber feet to reduce vibrations. These can be replaced with spikes if preferred (M6). The rubber feet are adjustable.

Why use two subwoofers?

We recommend using two subwoofers as there are several advantages this way. First, the system can play louder, and another reason is that more excitation points will cause fewer phase cancellations in the room. The result is a clearer soundstage. A more thorough study in wave distribution in a room can be found here. Read more >
Another advantage is that you can use a smaller amplifier but still reach the same sound pressure level.

Goals 99 W12.16S is a compact yet powerful subwoofer suitable for both HiFi and cinema setups, with power for those who want to feel the ground shaking and finesse for the epicure.
The following goals were set for the XTZ 99 W12.16S:
  • Flexibility with several tuning possibilities
  • High End quality
  • Capacity for high sound pressure levels
  • Relatively small cabinet
  • Quality at a competitive price
  • Timeless and clean design
Quality
  • Just like any other speaker we have used reality as our starting point trying to preserve a sound as natural as possible
  • Cabinet, amp and driver all offer a very high mechanical quality level
  • Finish and detail quality is very high, for example the high gloss black paint that presents an elegant impression
Power and Control
  • The high effiency driver and amplifier together create a powerful combination
  • 12" driver paired with a 300 watt amp is sufficient even for demanding customers
Flexibility
  • Using the tuning options the sound reproduction can be adjusted as far as you want to go in any room
Cabinet Design We have chosen 25 mm MDF offering a low level of internal resonance, and a cabinet construction reinforced using internal bars for maximum stability. The relatively small cabinet also adds to the stability.

Bass Driver We selected a 12" long stroke driver weighing 6,5 kg, with good transient response and capacity for loud SPL levels. The driver is constructed with a solid aluminum cast basket, a high flow tyoe that´s acoustically transparent. The membrane is a NPP type offering superior robustness and low weight. The magnet is a 100 oz unit.
The combination of a powerful magnet, low weight driver membrane and high performance suspension ensures both power and presicion.

The Amplifier The 99 W12.16S uses a 300 watt (RMS) amp to ensure good sound pressure capabilities and still maintain the precision. The amp is well equipped with a toroidal transformer and balanced input. A large heat sink makes sure the heat is dissipated safely. This amplifier offers tuning possibilities that passive filters cannot, phase, adjustable crossover frequency and level. There are two EQ-switches and a selectable highpass filter. The use of an active subwoofer also means the main amplifier just have to drive midrange and tweeters, which effectively reduces the load, often resulting in less distorsion.

Sound Characters And Settings By using the adjustments and included bass reflex port bungs, you can alter the sound character in many ways. This provides you with options to achieve exactly the kind of sound you want.

Level Adjustment The listening volume can be adjusted in respect to the rest of the speakers thanks to the active amplifier.

Crossover Frequency The upper crossover frequency can be adjusted between 40 - 250 Hz. Thanks to this you can alter the bass character from deep to "light" for a optimal integration with the rest of your speakers and the room properties.

EQ-Switch EQ 1 Raises the level around 50Hz with 7dB.
EQ 2 Raises the level around 25Hz with 7dB.

Highpass Filter The high pas filter cuts the lowest parts of the bass region. This can be useful in some cases when the room amplifies the lowest frequencies a lot, resulting in boomy bass and poor precision.


Phase adjustmentThe phase can be adjusted without steps from 0 - 180 degrees.

Room Tuning - Mechanical boundary frequency adjustmentUsing the included foam bungs you can alter the bass character of the subwoofer by plugging the reflex ports.
The picture below shows three different bass characters. By adjusting phase, crossover frequency and level the character can be further adjusted.
