This 5-Step supplemental article assumes you already have a home theatre system and simply want to improve the bass response for better impact and accuracy. This article also assumes you’ve properly set up the bass management in your AV receiver or processor and made all of the necessary connections to your speakers and subwoofers.
If you’re running only one subwoofer, it may be time to upgrade and get a second matching sub. Dual subwoofers are ALWAYS better than a single subwoofer for distributing uniform bass across a wider listening area and also coupling very low frequencies for greater depth and dynamic range.
Here are the 5 Steps Towards Better Bass in Your Home Theater Room:
- Subwoofer Location (preferably multiple subs) – Follow our pictorial guidelines in our Subwoofer Setup Article for suggestive placements or our Subwoofer Crawl. There are multiple locations that can work in your room so finding the right spots is worth the effort to greatly improve sound quality and depth. Positional EQ(Listening seat location) – where you place your listening seats also determines sound quality NOT just in bass but for the overall home theatre surround envelop. Keep your seating away from back and side walls if possible. Backwall placement is a maximum pressure zone where you will hear very loud but not accurate bass. If you can move the couches at least 1/4L of the room away from the backwall, you will ensure more accurate bass reproduction.
- Positional EQ – Believe it or not you can equalize the sound of your speaker/sub system simply by moving your theater chairs or couches. Proper seating location can have a huge impact in the quality of bass you hear. You generally want to avoid placing your seats up against a back or side wall. We recommend locating the seats at least 1/4L (L = length of the room) away from the back wall to reduce excessive bass energies caused by build up of standing waves. Locating a seat to a sidewall will shift the balance of the sound towards the closest surround speaker while also severely impacting stereo imaging of the front left/right speakers. Instead, apply symmetry and line of sight principles when locating your couches so that every seating location has a direct unobstructed path of sound to each speaker and the front left/right speakers are equidistant for true stereo imaging.
