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 MartinLogan 600X weighs 15.91kg / 35lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the SPL-100 6% heavier than the Dynamo 600X.
