Let's have a brief look at the main features of ELAC Varro PS350-BK and B&W ASW610 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 ELAC Varro PS350-BKand B&W ASW610 have a single woofer setup however the ELAC Varro PS350-BK's woofer is 12-inch whereas the B&W ASW610 features a 10-inch woofer.

Cabinet Type
The ELAC Varro PS350-BK 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 B&W ASW610 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 ELAC Varro PS350-BK's and B&W ASW610's external dimensions. ELAC Varro PS350-BK has external dimensions of 439.0 x 418.0 x 420.0mm (17-1/4inch x 16-7/16inch x 16-1/2inch) whereas B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm (12-5/8 x 12-1/4 x 15-1/2inch).
ELAC Varro PS350-BK is clearly the larger of the two speakers. Its body is 106mm wider, 118mm taller and 26mm deeper than B&W ASW610.
Below you can see the front view size comparison of ELAC Varro PS350-BK and B&W ASW610 in scale.

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 ELAC Varro PS350-BK is approximately 1755.6cm2 / 272.1inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Varro PS350-BK requires 43% more surface area than the ASW610 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 ELAC Varro PS350-BK weighs 21.86kg / 48.1lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the Varro PS350-BK 74% heavier than the ASW610.
