In this review, we will be comparing LX-10SUB MKII and KUBE 10b, two Powered Subwoofer speakers from Mission and KEF. 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 Mission LX-10SUB MKII and KEF KUBE 10b first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Mission LX-10SUB MKII and KEF KUBE 10b compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Mission LX-10SUB MKIIand KEF KUBE 10b have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
LX-10SUB MKII has a frequency range of 40-200 Hz whereas KUBE 10b has a frequency range of 24-140 Hz. With a minimum frequency of 24Hz, the KUBE 10b can go significantly deeper on the low side and provide stronger bass compared to the LX-10SUB MKII's min frequency of 40Hz.
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 Mission LX-10SUB MKII 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 KEF KUBE 10b 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
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Mission LX-10SUB MKII's and KEF KUBE 10b's external dimensions. Mission LX-10SUB MKII has external dimensions of 447.0 x 312.0 x 407.0mm ( 17-5/8 x 12-5/16 x 16inch) whereas KEF KUBE 10b has external dimensions of 372.0 x 356.0 x 397.0mm ( 14-5/8 x 14 x 15-5/8inch) .
KEF KUBE 10b is 75mm shorter and 10mm less deeper than Mission LX-10SUB MKII but it is also 44mm 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 Mission LX-10SUB MKII is approximately 1269.8cm2 / 196.8inch2 and base area of the KEF KUBE 10b is approximately 1413.3cm2 / 219.1inch2. The LX-10SUB MKII requires 10% less surface area than the KUBE 10b 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 Mission LX-10SUB MKII weighs 16.00kg / 35.2lbs and the KEF KUBE 10b weighs 17.50kg / 38.5lbs. This makes the KUBE 10b 9% heavier than the LX-10SUB MKII.
Here is a comparison of how LX-10SUB MKII and KUBE 10b's weights compare with the average, max and min weights in Powered Subwoofer class.
