In this review, we will be comparing SB-1000 Pro and SPL-150, two Powered Subwoofer speakers from SVS and Klipsch. 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 SVS SB-1000 Pro and Klipsch SPL-150 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.Both SVS SB-1000 Proand Klipsch SPL-150 have a single woofer setup however the SVS SB-1000 Pro's woofer is 12-inch whereas the Klipsch SPL-150 features a 15-inch woofer.
Frequency Response
SB-1000 Pro has a frequency range of 20-270 Hz whereas SPL-150 has a frequency range of 18-125 Hz. With a minimum frequency of 18Hz, the SPL-150 can go slightly deeper then the SB-1000 Pro's min frequency of 20Hz.
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 SVS SB-1000 Pro has a Acoustic Suspension type cabinet. 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. On the other hand the Klipsch SPL-150 have Bass Reflex type enclosure. 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.
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 SVS SB-1000 Pro's and Klipsch SPL-150's external dimensions. SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm (13-1/2inch x 13inch x 15-13/16inch) whereas Klipsch SPL-150 has external dimensions of 547.0 x 496.0 x 604.0mm (21-1/2 x 19-1/2 x 23-3/4inch).
Klipsch SPL-150 is clearly the larger of the two speakers. Its body is 165mm wider, 204mm taller and 202mm deeper than SVS SB-1000 Pro.

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 SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2 and base area of the Klipsch SPL-150 is approximately 2995.8cm2 / 464.3inch2. The SB-1000 Pro requires 56% less surface area than the SPL-150 which gives it a small advantage 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 SVS SB-1000 Pro weighs 11.82kg / 26lbs and the Klipsch SPL-150 weighs 34.27kg / 75.4lbs. This makes the SPL-150 190% heavier than the SB-1000 Pro.
Here is a comparison of how SB-1000 Pro and SPL-150'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.
Klipsch SPL-150 needs about 125% more floor area. Klipsch SPL-150 stands 202mm further into the room. Klipsch SPL-150 is 204mm taller.

A sealed subwoofer against a ported 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 (20Hz vs 18Hz). |
| Amplifier power | evenly matched | Much the same amplifier (325W vs 400W RMS) - under 1dB apart. |
| Driver area | B | Klipsch SPL-150 moves more air: 15" against 12" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | SVS SB-1000 Pro is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch SPL-150 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Speaker-level inputs | A | SVS SB-1000 Pro takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Cabinet size | depends | SVS SB-1000 Pro is about 72% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Warranty | A | SVS SB-1000 Pro carries 5 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 | SVS SB-1000 Pro costs less - $600 against $1,399, about 57% less. |
A SVS SB-1000 Pro B Klipsch SPL-150
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?
SVS SB-1000 Pro has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Films or music? If this is mainly a home cinema, Klipsch SPL-150 will hit harder for the money; if it is mainly for music in a normal-sized room, SVS SB-1000 Pro is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, SVS SB-1000 Pro is the only one of these two you can connect at all.
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.
