Andrew Welker: In this video we’re going to discuss positioning our LFR1100 omnidirectional speakers – both placement and how to wire them up; in particular, some of the settings on the DSP unit.
As many of you know the LFR1100 is omnidirectional, and that just means it radiates sound in 360 degrees – in all directions. To achieve that, there is a complement of drive units – two midranges and two tweeters – on the back. Because of that, the relative placement of the LFR1100 to the back wall, and the angle at which you’ve got it to the back wall, influences the soundstage, and the way that the sound is going to blend at the listening position.
So one of the things that we recommend – if at all possible – is to allow a couple of feet from the rear of the speaker to the back wall. In this setup here, it’s about 2 feet. If however you need to get the speaker closer than that, there is a boundary compensation switch on the back of the unit.

Okay, I admit it’s the skinniest video ever made! But you try to get these speakers in a frame with Axiom’s Andrew Welker, who designed the Omnidirectional LFR1100s together with Ian Colquhoun. Watch the video (filmed in Axiom’s anechoic chamber) or read the transcript below to find out what challenges are faced when you are designing loudspeakers with drivers on the front and rear panels of the speaker.
Andrew: Omnidrectional speakers are probably one of the more challenging types of designs that a loudspeaker designer can undertake. Part of the reason is that you have to deal with a lot of factors in terms of how the speaker interacts with the room, and how the different parts of the speaker interact with one another. Log in

I recently spent a lot of time with the new LFR1100 omnidirectional speakers, and something had me curious. If you’re like me, you may have been thinking to yourself Sure, I know that the intials DSP stand for Digital Signal Processor, but what the heck is the audio DSP doing to those speakers anyway?
