Centre speaker sounding 'boxee'?

With some tho not all source/programmes the centre can sound a little 'boxee'. Can I reduce this by adjusting the eq and if so what frequencies need increasing or decreasing? My experiments have not yet proved useful.
Cheers
PS. Speaker position also fails to solve the issue.

RE: Centre speaker sounding 'boxee'?

It depends at what frequency/frequencies the boxiness is occurring. That's assuming the EQ could tame it somewhat. You may find that it is something that is inherent in the speaker itself and can't really be eridicated.

RE: Centre speaker sounding 'boxee'?

Generally the yamaha peq should be set at flat,so stopping any spikes in freq.The problem you are experiancing is as you say down to the audio source,have you tried any of the yam's dsp on such occasions Robin?

When listening to a music broadcast,from either sky or dvd i use the dsp to give me a ''live club feel''.

Usually avoid dsp/processing like the plague. However, I am finding 'spectacle' and 'drama' improves rhe balance on some DProLogic broadcasts. Sometimes I think the state of my ears or state of mind fools me to a greater degree than tweaking. Just too many variables in the listening equation.

An avr is all about tweaking things,for stereo and 5.1 broadcasts i always use the dsp...mainly the drama/sci-fi:)

RE: Centre speaker sounding 'boxee'?

Hi Rob,

Are the pics in your sig still current? If so, and your centre speaker is still mounted inside your wooden AV cabinet, that is most likely the reason your centre sounds 'boxey' because you have placed it essentially . . . erm . . . in a box.

You have done a fair bit of reading (and work) on treating your room, so I'm sure you already know that speakers radiate sound in all directions - its the main reason that many poeple (including the manufacturers) advocate standing them in free space - to avoid reflections of the sounds that aren't radiated directly at the MLP being reflected back towards the MLP within a 20ms time period. The alternative for us mere mortals with normal sized listening rooms, where such placement isn't practical, is treating the room to try and absorb or diffuse some of the non-directional or reflected sounds, which can work wonders as you have found.

Exactly the same applies to your centre speaker as it doesn your FR and FL speakers. Sounds radiating from the speaker in any direction other than forwards, will be bouncing around inside that cabinet like pinballs before making their way out the front, creating that 'boxey' sound and also inteferring with the direct radiated sounds.

The best thing you can do (if practicality allows) is do away with the cabinet and mount the centre channel on a dedicated stand. In addition another of your acoustic panels on the wall behind the centre channel will aid clarity and separation also.

An alternative, if the cabinet has to stay, is to line it with mini rockwool panels (filling as much of the open space as possible - up to, or even touching, the speaker) - it won't be as good as a dedicated free-standing speaker stand, but it may help. This is what would be done in a studio where speakers are often soffit mounted.

Hope that helps.

Cheers,

Gareth
