This 5-Step supplementary post assumes you already own a home theatre system and want to improve the bass response for more impact and accuracy. This article also assumes that you’ve configured your AV receiver or processor’s bass management and made all of the required connections to your speakers and subwoofers.

If you just have one subwoofer, it might be time to update and purchase a second one that matches. Dual subwoofers are ALWAYS superior to a single subwoofer in terms of delivering consistent bass across a larger listening area and coupling very low frequencies for more depth and dynamic range.

Subwoofer Location

There are a variety of places that can work in your space, so putting in the time to identify the best ones will dramatically enhance sound quality and depth. Positional EQ (Listening Seat Location) – Not only does where you put your listening seats affect sound quality in the bass, but it also affects the whole surround envelope in your home theatre. If at all possible, sit away from the back and sidewalls. Back wall placement is a high-pressure zone where you’ll hear many basses, but it won’t be correct. You may assure more accurate bass reproduction by moving the sofas at least 1/4L of the room away from the back wall.

Positional EQ

You may equalize the sound of your speaker/subsystem by just shifting your theatre seats or sofas, believe it or not. The quality of bass you hear can be greatly influenced by where you sit. You should try to avoid seating against a back or sidewall as much as possible. To avoid excessive bass energy generated by standing waves, we propose placing the chairs at least 1/4L (L = length of the room) away from the rear wall. When a seat is near a sidewall, the sound balance is shifted to the closest surround speaker, and the stereo image of the front left/right speakers is significantly impacted. Instead, use symmetry and line-of-sight principles to place your sofas such that every seat has an unobstructed sound path to each speaker and the front left and right speakers are equally spaced for genuine stereo imaging.

Proper time alignment

If you choose an AV receiver or processor with two independent subwoofer outputs, you may change the delays and levels for each subwoofer separately. Variable phase on the subwoofer(s) can also help you dial in the relationship between the subs and the main speakers.

Level matching

To guarantee an ideal mix, make sure the levels between your subwoofers and speakers are appropriately balanced. Multi-sub uses subwoofers with comparable output capabilities and levels to average out room modes and produce a broader, more equal sweet spot in your listening area. Lowering the volume of a well-positioned nearfield subwoofer to address problematic room sickouts at the listening location might be useful in decreasing localization of that specific subwoofer’s pressure waves in some cases.

REW Kit Manual and/or Auto-EQ

It’s time to add the icing to the cake once you’ve correctly set up and incorporated your subwoofers into your home theatre. Once the seat-to-seat variation in bass response is reduced, EQ becomes a very useful technique for reducing residual modal issues at bass frequencies for the whole sitting area. Parametric equalization does this by removing that energy from the space to reduce the troublesome frequencies. You can actually increase the level a few dB higher for more impact than the rest of the speakers once the bass has been flattened without being unpleasant or boomy. See our Subwoofer Setup Article for more details, including samples of how to use DSP to equalize a multi-subwoofer setup. Remember that applying a single equalization correction curve to all subs at the same time is typically preferable. If auto EQ doesn’t help your system sound better, try tweaking its parameters like bass management, delays, and EQ (if adjustable). If it still sounds off, turn it off and use manual EQ instead.

Conclusion

For the most seamless mix, a genuine home theatre playback system should have consistent (level) bass for all listening seats, lots of dynamic range, and a smooth natural frequency response over the whole listening area. The best approach to get strong bass is to use passive room treatments, numerous subs, correct speaker/subwoofer and seating locations and configuration, and active equalization to reduce modal peaks and nodal dips. Don’t overlook any of these tools when it comes to equalization (OR) adjustment. The key is correct subwoofer placement and configuration, which eliminates guesswork and reduces chasing your tail to discover the ideal settings that produce the best-measured performance.

It’s difficult to go back after hearing a well-tuned home theatre with a smooth and equal basis across the listening area. The time and work it takes to effectively incorporate numerous subwoofers into your cinema room are well worth it. You can build a home theatre experience that surpasses even the greatest Cinemas with the right equipment, know-how, and patience. When tuning your theatre, it’s critical to be methodical and persistent.
