Axiom Engineer Andrew Welker continues with his description of how to design an in-wall loudspeakers to avoid any problems with reflections and diffractions1.
Andrew: Part two, in continuation of part one. A couple of important details. One, many in-wall speakers that you’ll see on the marketplace actually are sunk into the wall so that the drive units sit below where the drywall surface or the wallboard surface would be. That’s actually a very bad thing acoustically, because the wall edges that stick out past the drivers cause reflections and what’s called diffractions around the drive unit. So instead of getting a nice even spread and a spacious sound, you can get a very localized and closed-in sound, which sounds very unnatural. Log in

One question that several of you have asked pertains to designing an in-wall speaker: how does it differ from designing a regular speaker? What factors do you have to take into account when you’re engineering it?
I caught up with Andrew Welker in our anechoic chamber (this time we put the floor in so I could turn the camera around!) and asked him about his strategy. Log in

You’ve ordered the latest Hollywood blockbuster, stocked the cupboard with popcorn, and invited the neighbors over for ‘the big demo’: what’s left to do before debuting your new home theater system? In a word, configuration. Setting it up properly can make all the difference between a polite “Isn’t that a lot of speakers?” and “Wow – honey you need to get us one of these for our house!” So what exactly do you need to do?

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
