In this review, we will be comparing SPL-120 and Sub 1000 F, two Powered Subwoofer speakers from Klipsch and Focal. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of Klipsch SPL-120 and Focal Sub 1000 F first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Klipsch SPL-120and Focal Sub 1000 F have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
SPL-120 has a frequency range of 24-125 Hz whereas Sub 1000 F has a frequency range of 24-200 Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type
The Klipsch SPL-120 has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the Focal Sub 1000 F have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Klipsch SPL-120's and Focal Sub 1000 F's external dimensions. Klipsch SPL-120 has external dimensions of 450.0 x 375.0 x 540.0mm (17-11/16 x 14-3/4 x 21-1/4inch) whereas Focal Sub 1000 F has external dimensions of 421.0 x 401.0 x 474.0mm (16-9/16 x 15-3/4 x 18-5/8inch).
Focal Sub 1000 F is 29mm shorter and 66mm less deeper than Klipsch SPL-120 but it is also 26mm wider.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Klipsch SPL-120 is approximately 2025.0cm2 / 313.9inch2 and base area of the Focal Sub 1000 F is approximately 1900.7cm2 / 294.6inch2. The SPL-120 requires 7% more surface area than the Sub 1000 F which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The Klipsch SPL-120 weighs 20.45kg / 45lbs and the Focal Sub 1000 F weighs 21.36kg / 47lbs. This makes the Sub 1000 F 4% heavier than the SPL-120.
Here is a comparison of how SPL-120 and Sub 1000 F's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
Near-identical footprints. Klipsch SPL-120 stands 66mm further into the room. Klipsch SPL-120 is 29mm taller.

A ported subwoofer against a sealed one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (24Hz vs 24Hz). |
| Amplifier power | B | Focal Sub 1000 F has the bigger amplifier - 1000W against 300W RMS, about 5.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | Klipsch SPL-120 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; Focal Sub 1000 F is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Wireless option | depends | Only Klipsch SPL-120 offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Warranty | B | Focal Sub 1000 F carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | Klipsch SPL-120 costs less - $499 against $2,099, about 76% less. |
A Klipsch SPL-120 B Focal Sub 1000 F
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Focal Sub 1000 F measures better, Klipsch SPL-120 costs about 76% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Klipsch SPL-120 will hit harder for the money; if it is mainly for music in a normal-sized room, Focal Sub 1000 F is usually the easier one to make sound right. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $499 each, two Klipsch SPL-120 cost about $998 against $2,099 for one of the other, which is worth a thought.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
