More precisely, a “slow” subwoofer is one that has excessive overhang: the cone keeps moving long after the drive signal has stopped, which conveys the impression that the bass is “slow.”. For example, if you have a 20′-wide room, don’t put the subwoofer 10′ from each wall. Simply run in wall and/or in ceiling speaker wires to the central wall point of your system's components. Some speakers have optional wall mounting brackets. Connect the Dots. Unless the main speakers and subwoofer are identical distances from your ears, those two soundwaves will arrive at your ears at different times; that is, they will have a phase shift between them. One of the most common ways of connecting speakers to a receiver or amplifier is through the use of binding posts. Learn technology behind the award winning EVO-IP HDMI over IP system. In addition to a subwoofer, there is also the Tactile Transducer. Press Esc to cancel. Do not just drill a hole in the wall, that will look bad and crumble over time. You can also get more dynamic impact and clarity from your subwoofer by placing it close to the listening position. Connect the speaker wire or banana plugs to the front. On some older AVRs, a direct wire connection where the subwoofer's speaker wire connects directly to the AVR's "subwoofer out" speaker terminal is utilized. A full-range loudspeaker offers no such control. In addition, the electronics inside a subwoofer can create a phase shift in the signal. Now, connect the other end of the speaker wire to the speaker wire terminals on the subwoofer. Most modern Audio/Video Receivers (AVRs) have a dedicated subwoofer connection located on the rear input/output panel. Reference your AVR's manual for more information on its auto calibration feature. Frequencies below the crossover point are reproduced by the subwoofer; frequencies above the crossover point are reproduced by the main speakers. Fasten the insert to the wall plate with the shorter screws. The Tactile Transducer produces only the vibrations that come from low-end reproduction. Put simply, it is possible to greatly improve a system’s performance by adding a subwoofer (or a pair of subs). Crawl around the floor on your hands and knees (make sure the neighbors aren’t watching) until you find the spot where the bass sounds smoothest, and where each bass note has about the same volume and clarity. Adapted from The Complete Guide to High-End Audio (Fifth Edition). This problem of room-mode excitation can be ameliorated by using two (or more) subwoofers; each subwoofer will excite different room modes, substantially smoothing out the room’s low-frequency response.

If you're running cable through the wall to a flat-panel HDTV or projector, the HDMI wall plates from Outdoor Speaker Depot will give you a clean, professional look. Adding a line-level crossover and power amp turns the passive subwoofer into an active subwoofer, and also makes the system bi-amplified. The 7.2 Home Theater Connection Wall Plate from Vanco International is for use with speaker wire to Connect Audio Speakers and Subwoofers to a Receiver/Amplifier. The satellite speakers can be positioned for the best soundstage without regard for how that position affects the bass response. Excerpted and adapted from The Complete Guide to High-End Audio (Fifth Edition). Two subwoofers drive the air in the room more uniformly, with fewer standing waves. There are wall plates for just about any connector that's out there. Another factor that can make integrating a subwoofer difficult is matching a slow subwoofer to taut, lean, articulate main speakers. As with full-range speakers, avoid putting the sub the same distance from two walls. Similarly, don’t put the subwoofer near a corner and equidistant from the side and front walls. The Absolute Sound is the world’s preeminent source of expert reviews, features, and commentary on high-performance audio and music. Find low everyday prices and buy online for delivery or in-store pick-up Moreover, adding a separate power amp for the subwoofer greatly increases the system’s dynamic range and frees the main-speaker amplifier from the burden of driving the sub. Now, from a test CD or device app that offers pure test tones, select the track whose frequency is the same as the subwoofer’s crossover frequency. Cat5e wall plate socket designed to suit standard Australian New Zealand wall plates. hifibooks.com. If you have small speakers that don’t go very low in the bass and you set the crossover frequency too low, you’ll get a “hole” in the frequency response. It’s worth noting that the best integration results from adding two (or more) subwoofers to your system. For example, if you have a 20′-wide room, don’t put the subwoofer 10′ from each wall. Most of these products actually employ woofers that are simply driven by an integral power amplifier. Unless you later move the subwoofer or main speakers, you need to perform this exercise only once. The Absolute Sound team is proud to highlight Martin Logan and Paradigm, known for loudspeaker innovation. The two out-of-phase waves cancel each other, producing very little bass.

The right thing to do is … Sitting near the subwoofer causes you to hear more of the sub’s direct sound and less of the sound that has been reflected around the room. Now for the bad news: More often than not, subwoofers can degrade a playback system’s musical performance. Second, the subwoofer’s bass quality may be poor. It is much more cost-effective to build a subwoofer enclosure than it is to build the large enclosure of a full-range loudspeaker (to accommodate large woofers), which may have expensive cabinet construction and wood or paint finishes. Some subwoofers are designed to extend the system’s bass response without filtering bass from the signal driving the main speakers. Wall plate - use a Brush style plate and pull the cable through the wall without adding an unnecessary break in the cable run. FREE Shipping on orders over $25 shipped by Amazon. Passive Subwoofers Subwoofers come in two varieties: passive and active. If all these details are handled by the same designer, you’re much more likely to get a smooth transition than if the subwoofer is an add-on component from a different manufacturer. This is the most accurate way to set a subwoofer’s phase control, because it’s easier to hear and identify the point of maximum cancellation than the point of maximum reinforcement. Now, when you return your main speakers to their proper connection (putting them back in phase with the subwoofer), they will be maximally in-phase with the sub. Some self-powered subwoofers are able to take the speaker-level signals from the amp and extract the low-end sounds. To order call (800) 841-4741. Connect speaker cable from the front-left and front-right terminal outputs located on the rear panel of your AVR. This should give you a span of exposed cable at the conclusion of every segment. Copyright © 2021 The Absolute Sound. The reasoning behind this is that if you’ve paid good money for something, you want to hear what it does. This crossover frequency is adjustable to allow you to select the frequency that provides the best integration with the main speakers.

The active subwoofer’s internal crossover may not be of the highest quality. This simple guide assumes that you already have an Audio/Video Receiver, including home theater speakers, and discusses how to determine the type of subwoofer you own, how to connect it, and where it should be placed within a room. A passive subwoofer is just a woofer or woofers in an enclosure that must be driven by an external amplifier. Subwoofer Pros and Cons Adding an actively powered subwoofer can greatly increase your system’s dynamic range, bass extension, midrange clarity, and ability to play louder without strain. In one variation of the passive subwoofer, the same stereo amplifier driving the main speakers also powers the subwoofer. They deliver that room-shaking bass that can be found in most movies and are also versatile enough to deliver warm, smooth bass found in most musical tracks. The word “slow” in this application is not technically correct, but vividly describes how such a subwoofer sounds. A well-integrated subwoofer produces a seamless sound, no boomy thump, and natural timbre. The additional amplifier power and low-frequency driver allow the system to reproduce musical peaks at higher levels. Consequently, many subwoofers sound bloated, “slow,” and lacking in detail. Most modern AVRs come with their own version of an auto calibration feature which can get your entire home theater system, including the subwoofer, sounding optimum regardless of the subwoofer's placement. Some self-powered subwoofers are able to take the speaker-level signals from the amp and extract the low-end sounds. Achieving good integration between small speakers and a subwoofer is easier if you buy a complete system made by one manufacturer.
