In this review, we will be comparing RP-1400CSW and MiniVee X, two Powered Subwoofer speakers from Klipsch and Velodyne. 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 RP-1400CSW and Velodyne MiniVee X 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 Klipsch RP-1400CSWand Velodyne MiniVee X have a single woofer setup however the Klipsch RP-1400CSW's woofer is 14-inch whereas the Velodyne MiniVee X features a 8-inch woofer.
Frequency Response
RP-1400CSW has a frequency range of 15-180 Hz whereas MiniVee X has a frequency range of 32-180 Hz. With a minimum frequency of 15Hz, the RP-1400CSW can go significantly deeper on the low side and provide stronger bass compared to the MiniVee X's min frequency of 32Hz.
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.

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 RP-1400CSW's and Velodyne MiniVee X's external dimensions. Klipsch RP-1400CSW has external dimensions of 444.0 x 421.6 x 421.6mm (17.48inch x 16.6inch x 16.6inch) whereas Velodyne MiniVee X has external dimensions of 300 x 290 x 290 mm ().
Klipsch RP-1400CSW is clearly the larger of the two speakers. Its body is 131.6mm wider, 144mm taller and 131.6mm deeper than Velodyne MiniVee X.
Size, drawn to scale
Both speakers 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 surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Klipsch RP-1400CSW needs about 111% more floor or shelf area. Klipsch RP-1400CSW is 132mm deeper, so it stands that much further out from the wall. Klipsch RP-1400CSW is 144mm taller.
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 RP-1400CSW is approximately 1777.5cm2 / 275.5inch2 and base area of the Velodyne MiniVee X is approximately 841.0cm2 / 130.4inch2. The RP-1400CSW requires 111% more surface area than the MiniVee X 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 RP-1400CSW weighs 27.08kg / 59.6lbs and the Velodyne MiniVee X weighs 15.00kg / 33lbs. This makes the RP-1400CSW 81% heavier than the MiniVee X.
Here is a comparison of how RP-1400CSW and MiniVee X's weights compare with the average, max and min weights in Powered Subwoofer class.

Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | A | Klipsch RP-1400CSW goes deeper - 15Hz against 32Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | Klipsch RP-1400CSW has the bigger amplifier - 500W against 350W RMS, about 1.5dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1400CSW moves more air: 14" against 8" is 3.06x the cone area, not the 1.75x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Speaker-level inputs | B | Velodyne MiniVee X 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 | Velodyne MiniVee X is about 68% 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. |
| Price | A | Klipsch RP-1400CSW costs less - $1,100 against $1,299, about 15% less. |
A Klipsch RP-1400CSW B Velodyne MiniVee X
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?
Klipsch RP-1400CSW is the easier recommendation: it leads on most of the measured areas and costs less. Take Velodyne MiniVee X if one of the "depends" rows describes your room. Check your amplifier first: if it has no subwoofer or preamp output, Velodyne MiniVee X is the only one of these two you can connect at all. If placement is the constraint - a corner, behind a sofa, under a desk - Velodyne MiniVee X is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
