I use these large 18inch subs for mostly large venues and for club music also live music! These are heavy but although judging on their size it would seem like the adequate weight. Can't go too light ! That being said the large quality sub woofer drivers give an excellent amount of clarity and volume. A great thump when both actively working together, these passive are also a great buy for budgets or even beginners.
If you ask me behringer can be reasonably cheap but of high quality. 1600 watt peak is the sound size you need to make the improvement with top speakers that worth while especially if space for travelling is an issue when commercial vehicle not available. These fit very comfortable in a small van such as a VW CADDY.
For price very very good, but remember always keep middle of road at least when buying an amp! You must get the full potential from your speakers. Between 15inch tops anything over 1000w peak will and do work great with these for your large but mobile sound system that will suit most venues of small and large.
They are well built and have the carpet exterior which is always friendly with transport and the likes.
Overall if transport is not an issue and you have some sort of wheel board or second pair of hands to help you and also a decent amp maybe from such as crown or t amp will drive these to an impressive clarity. Then you are good to go, price is perfect, they look great, bigger the better as they look beastly and look to take a driving. Nice and very powerful, 10/10!
