FAQ - 360 Passive with Aktiv Bass
Linn 360 common FAQ's to both PWAB and Exakt variants
The 360 has two 8” bass drive units just like the Klimax 350. How does it produce more bass?
- The bass drivers in the 360 loudspeaker have the same surface area but are capable of greater than twice the excursion of the units deployed in the Klimax 350. This means they can move more than twice the amount of air.
- This is equivalent to the Klimax 350 with four bass drivers.
What is the Linn Power DAC?
- Linn Power DAC is a new amplifier technology specifically designed for bass systems that require high performance, high power, and high efficiency. The Linn Power DAC is a true digital amplifier combining DAC and amplifier into a single process.
- At high playback levels the Power DAC reduces distortion by over 10 dB compared to conventional designs.
Is the 360 bass system servo controlled?
- No. In 360 we have taken a feed-forward approach.
- The response of each bass drive unit is measured, and individual compensation filters are calculated. These filters are then applied in a feed-forward fashion to achieve the same result as the feed-back servo system.
- The 360 bass drive units are also far more linear than those previously used, so distortion correction is no longer required.
Linn 360 PWAB FAQ's
Why is 360 PWAB not a purely passive speaker?
- The compact size of the 360 bass system requires electronic compensation to achieve an extended bass response. This compensation cannot be implemented passively, so active amplification is required.
Why is the bass signal digitized in 360 PWAB?
- The analogue signal supplied to the 360 PWAB is digitized and fed into the new Linn Power DAC.
- The Power DAC has been designed from the ground up to drive the 360 bass system. It offers the lowest distortion and greatest efficiency of any amplifier class for this application.
Why can’t you bypass the internal lower bass amps on 360 PWAB to use Klimax Solos externally?
- The bass extension system in 360 requires an extraordinary amount of power and voltage gain, far more than even the Klimax Solo can provide, so performance would actually suffer if external amplifiers were used.
Do you still require 2x Exaktboxes for an externally Exakt 360 PWAB?
- No. The active bass system contains its own ExaktEngine, so a pair of 360 Arrays (tweeter, midrange and upper-bass) can be driven by a single 6-channel ExaktBox.
