Speaker Placement or Room


Speakers are Vandersteen 3A's. I've got them set up according to the placement instructions that came with the manual. In general they sound really good.

I've just taken some readings with my Radio Shack spl meter and the Rives test disc, using the frequencies that are corrected for that device. I know no room is perfect and a flat response will not happen, but for the most part everything is "relatively flat". However, I'm getting a huge dip between 80hz & 100hz. 80hz is -23db, 100hz is -12 db and 125hz is -15db. 160hz is back to flat.

Is this an issue of speaker placement or is it the room? If it's the room, where do I begin to minimize these dips?

Thanks.

There's no set rule on where to position your speakers. With the Vandys I'd stay close to what is recommended but you can angle them or whatever. EVERY room is different so you just do what you can.

Room treatments can help alot. At least two bass traps could help your room significantly. You can make them yourself for 50 bucks a piece. Email me if you want to know how. YOu also try the Acoustics Circle at audiocircle.com.

Another option is the Behringer DEQ 2496 digital equalizer. You can use this purely in the digital domain. It's only 300 bucks with a microphone, the ECM 8000, if you google around or buy used. The learning curve is very steep. The potential for a very large improvement in sound quality is likely.

Some people actually like the onboard dac in the Behringer but you can use an outboard dac like most of us so it's completely transparent. This thing is no toy and has way more features than you'll ever use. It even has an AUTOEQ mode where you can put in a room curve and it will do it for you!

Another nice feature is the spectrum analyzer. The Vandys are a pretty good speaker but any speaker needs good acoustics to perform as it was designed. The room just changes everything so much and treatments are such a bargain for the improvement in sound it's crazy to not do it.

Hope this helps you, Cheers
