Subwoofer Calculator & Recommendations by Room Size

There is a distinction to be made between attempting to pressurise a place to a specific pressure level and achieving strong bass performance inside a specific listening region. And you\'re presumably here for strong bass performance in a certain location.

When selecting the best 10 inch subwoofers for your room size, factors such as room volume and concept, subwoofer size, power output, frequency range, and explosiveness must all be considered. It\'s not about having the cleanest bass; it\'s about having the greatest bass for you.

Because there are too many variables to make this a precise science, no one has come up with a general rule of thumb for subwoofer size by room size.

However, our test results should assist you in establishing how much output you\'ll need in your room to reach reference levels.

We hope that the approach we used to define subwoofer room size capabilities would prove to be a useful subwoofer room size calculator for anybody trying to figure out which subwoofer is ideal for their listening location.

These calculations are "rule of thumb" calculations that allow you to make rapid judgments based on a few numbers. Let\'s get started!

How Did We Categorize Rooms and How Did We Determine Room Size?

When it comes to subwoofers, cubic feet is far more useful than square feet as a measurement of room size. It could be simpler to drive a 2515 room with a 10-foot ceiling than a 2010 room with a 30-foot ceiling. If your room opens out into another room, the volume (in cubic feet) of that new area must also be considered.

length (ft) width (ft) height (ft3) = cubic feet (ft3) (ft)

We\'ll be using cubic feet in this post, so if you\'re using the metre, divide the amount of cubic feet by 35.3 to get cubic metres.

1000 ft3 = 28.3 m3 is an example.

Room classification

In comparison to designated listening facilities such as music arenas or commercial movie theatres, most rooms are considered tiny.

The goal for a tiny listening environment, on the other hand, is no less important than for a vast hearing space.

We\'d like to be able to achieve reference levels with little distortion and compression. To reach reference levels, the speaker or subwoofer must work more in a bigger environment.

Based on comments from industry audio pros, we\'ve split room sizes into five groups that appear to be the most appropriate

Extra-small: less than 1200 ft3

1200 – 2000 ft3 is a small size.

2000–4000 ft3 is a medium size.

4000 – 6000 ft3 is a large size.

Over 6000 ft3 is considered extra-large.

Extra-tiny room (under 1200 cubic feet)

If your room is tiny – less than 1200 cubic feet – your listening position is likely just 8.5 feet from the television. You can\'t go wrong with subwoofers in that little area, whether you\'re searching for one for gaming, listening to music, or watching movies.

Similarly, for less than $300, you can acquire a budget-friendly Jamo C912 and have the subwoofer sink into the area rather than producing earth-shaking bass.

A small room (1200 – 2000 cubic feet) 

is a room with a limited amount of space. In an area of 1200 – 2000 cubic feet, a pair of sealed subs would produce great results. With just my PC12+ in sealed mode, I can pressurise a room that size.

​​If you\'re on a tight budget, a pair of Klipsch 12" speakers are hard to match.

If money isn\'t an issue, a pair of MartinLogan Dynamo 10s would be ideal. Even when attempting to chuff, it appears that the MartinLogan subs have the least amount of reported chuffing.

Several of my college students who tested the MartinLogan said it was the greatest 10′′ sub they\'d ever heard in terms of extension and minimal distortion, as well as the most difficult to chuff. If not properly set up and/or pushed to their limitations, all ported subs will chuff at some time.

In this room size, I\'m not sure you\'d get any benefits from buying more powered subs, and it might possibly have some drawbacks, such as possible port noise.

A pair of HSU VTF3, VTF15, or one of the 15′′ PSA subs, for example, would have a lot of headroom, and I don\'t think any of them will ever chuff provided the placement is good and the response at the listening location is optimal.

Medium-sized room (between 2000 and 4000 cubic feet)

My friend was completely free to undertake acoustic treatments, install bass traps, and purchase new subs when he bought a property with his own decent-sized man cave (about 15 by 14 by 12 feet).

He wanted to have multiple music and movie subtitles. He also wanted the system to be able to provide respectable levels at frequencies below 20 Hz.

He also didn\'t know much about subs and preferred the sealed over the ported model because it was smaller.

I suggested he get two good ported SVS PB-2000 Pro 12′′ subs, which can play loudly while also smoothing out the frequency response better than a single huge sub in a well-treated environment.

Get two Rythmik F12 sealed subs if you want sealed subs for the form factor. They can achieve 20Hz at -1dB (14Hz at -2dB; the SB16 can reach 16Hz at -6dB), but their large output and integrated DSP make them expensive.

Large room (between 4000 and 6000 square feet)

To begin with, if you want extreme bass, you\'ll need a lot of subs to pressurise a space larger than 4,000 cubic feet.

Second, with such a vast space, you should consider room proportions in terms of bass modes.

If your space is square and the height is evenly divided by the other dimensions, for example, you might expect a lot of variance with boomy and lifeless areas all over the place.

That means you\'ll need at least two excellent subs to produce a decently equal response throughout the listening area.

If you\'re on a budget, skip the whole room and go for a nearfield approach, which will cause your bottom to jiggle for less money.

If your space is typically shaped and you aren\'t on a budget, a pair of 15" REL Acoustics HT/1508 Predator speakers would be ideal.

Concentrate on the highest-performing, biggest subwoofer you can find for the greatest bang for your budget. The largest fantastic sub, not the biggest cheap sub. I\'d rather have a set of 13-inch SVS or HSU speakers than a 15-inch Klipsch. While "big" is significant, "great" is far more vital.

Room with plenty of space (over 6000 cubic feet)

I also have a large living area with 12-foot ceilings (about 25x35) (an open floor plan is excellent for us but terrible for listening to music and home theater).

If you want deep bass and prefer frequencies below 20 Hz, quad subwoofers may be the way to go. Two is a decent number, and four is fantastic.

I have a pair of SB16 Ultra speakers that cost roughly $4500, but I wouldn\'t suggest them for a space this large. For around $4500, you can acquire four SVS 13" SB-3000s.

A miniDSP 2x4HD and calibration mic are available for an additional 350 dollars. Then, greater than anything your receiver can do, you\'d tune each subwoofer independently.
