Aim: SYSTEM-1 from the outset was always going to be an active 3-way DSP speaker.

Amplifiers: The amplifiers are the latest generation Hypex n-core OEM modules. There are a pair of dedicated 100 watt amplifier for the tweeters, which have incredibly low distortion in the milliwatt and single digit watt region where a tweeter often operates.

Code Acoustics ha scritto:Cabinet Principle:

In small rooms, the speakers often have to sit close to the rear walls or in a corner. The problem with this is the speakers can easily excite room modes. These are specific frequencies predominantly in the bass region that relate to the physical dimensions of the room.

When a bass note in your music is around the frequency of the room mode (there will be several at varying frequencies) it will sound particularly pronounced and can literally sound like a ‘BOOM’. This is a rather annoying and obvious distortion, as it can completely take over the listening experience.

Sealed vs. Ported cabinet:



Ported speakers are particularly bad for activating these modes and the problem is exacerbated by these speakers needing to play at reasonable volumes to correctly activate the ports and sound neutral.

Various types of room modes:



Sealed speakers in contrast sound fairly neutral irrespective of volume and don’t cause booming anywhere near to the same extent. This in combination with good transient response, a gentle bass roll-off and limited re-radiation of energy, makes it the preferred choice.
