Our guide to the JBL install compact subwoofer range

Subwoofers are an integral part of an audio system, they help deliver a better sound and experience to the listener. A sub's job is to produce the lower frequencies, they give music depth and warmth. Subs can also be a good way to give your system a bigger sound whilst using small-format, easily distributed and less imposing high frequency speakers (see our specific guide to JBL sub/sat systems).

In this guide we'll look at the JBL install compact sub-woofer model options - floor standing, ceiling and pendant - and take a look at some of the issues to be considered when positioning a subwoofer. 

So first up, the JBL compact install subwoofer range ...

Compact JBL Install Subwoofers

JBL ASB6112

Personally, my favourite of all the JBL install subwoofers is the ASB6112. It's extremely compact but packs a hell of a punch for such a small 12" Sub. It is lightweight, with a large vent area for high output. It can be suspended using the M10 points or ground stacked. It really is a fantastic solution when you need to have a high impact sub that can also be hidden away.

JBL SB2110

The SB2210 is a dual 10" subwoofer and can be placed on the floor or can be mounted using the optional U-Bracket. It is a great choice for a variety of applications, it can be made IP rated when used with the rear input terminal covers (MTC-PC2 or MTC-PC3) so is a great choice  indoors or outdoors.

JBL Control 50S/T 

The Control 50 Sub is a fantastic compact sub. It gives small systems a much fuller sound, it can be utilised as a stand alone subwoofer or as a SUB/SAT system where you can mix and match with our Control 52 (surface mount) Control 42 (ceiling mounted) or control 62 (pendant form) speakers. You can use 2 or 4 satellite speakers when using the Control 50- sub system. The Control 50 comes with a wall mount bracket and its neat compact design fits in with most decors (it’s also available in Black or White and paintable!)

JBL Control 60P/S

Like the Control 50 sub the Control 60 pendant subwoofer has the unique feature of a built-in crossover so can run as a sub sat system, you can therefore use the 4 outputs for other small satellite speakers. With a built in Low Pass Filter (LPF) set to 125Hz all you need to do is send a full range signal to the pendant sub and the crossover will distribute that to 2 or 4 of the satellite speaker. Great for applications with open ceilings.



JBL Control 19CS/CST

The Control 19CS and 19CST are the same unit but the CST comes with a built-in transformer with tap settings of 15W, 30W and 75W @100v. It has an 8’ driver and has a Unique Nested Chamber™ design and Linear Dynamic Aperture™ port design that deliver high output from a compact enclosure, the units come with tile rails and C-shaped backing plate for fast easy installation. The Control 19CS can be connected into a system in a number of configurations: In parallel with full-range speakers resulting in a bass-overlap configuration (which is often acceptable) with an electronic crossover and separate amplifier channel, or in conjunction with an active or passive high-pass filter on the full-range speakers, thus taking advantage of the Control 19CS’s natural acoustic low-pass character.

JBL Control 40CS/T

Like the Control 19CS the Control 40CS/T is an in-ceiling subwoofer. It uses a high impact, 8" subwoofer with a built-in passive crossover network enabling the Control 40CS/T to be used as part of a subwoofer-satellite system when combined with the Control 42, 52 or 62 satellites.



Issues to consider when positioning subwoofers

Subwoofers are pretty much omni-directional (equal sound output in all directions). With high frequencies the sound waves are directed by the horn flare (and waveguide) of the speaker.  We don't have this control with Subs and low frequencies. Low frequencies also have longer wavelengths, so generally travel further. That’s why you will often hear the low frequency thump outside a club but not the higher frequency content until the door opens.


Most people want speakers hidden out of the way so they don't interfere with the decor or theme of the room. So what do they do? They put them up high in corners and put subwoofers in the corner out of the way. But is that doing more harm than good? Giving a subwoofer a boundary to work with could change the Subwoofers behaviour greatly.


If we place a speaker floating in midair away from all surfaces this is called free space and adds 0dB.

If we place a speaker next to 1 boundary whether it be a wall or a floor this will add 3dB and is called half space. The reason you would use half space is that instead of putting the sound out spherically (360 degrees horizontally and vertically), you are now only throwing the sound out in a 1/2 sphere so you are using the same amount of power but not wasting any energy where you don’t want it. The sound waves are now being put out into effectively half the amount of space this is how you increase level by 3dB. You also have 1/4 space as an option, this is two boundaries and will add an additional 6dB to the subwoofer.

You can go one step further and add 9dB by putting a sub in a corner this would be using three boundaries (2 walls and the floor). Some people will think ‘’wow that’s great you would be silly not to do this” and that a 9dB  corner solution should be the selected positioning due to it giving higher output levels and more LF.  

This does not always come as an advantage! Sometimes you just need to put the sub or the sound where it needs to be, you may find by putting the sub in a corner you are actually putting the speaker twice as far away as it needs to be (doubling the distance from the audience area or the listener means you're losing around 6dB in loss over distance).

You may also find that by adding the 9dB and placing your subwoofer in the corner of a room you might be exciting the room too much with your low frequency content. All rooms have resonance, frequencies that get reinforced by the physical shape and materials of the space and generally lower frequencies are what cause acoustic issues,so it's crucial to get your speakers in the correct position. It's always good to experiment with subwoofer positions and simply using your ears to listen will generally give you the best results.

So in a nutshell use boundaries to help with performance but do be cautious as sometimes less is more. Flying subs can waste energy and by simply placing them on the ground you could also save on installation costs as you won't need any additional bracketry.
