there not horrible, but u could prolly find something alittle better at the price..1 sub around the price of 3 of those ina decent sized box would prolly get louder...i guess it all depends on the sound ur lookin for too ur call lol just sayinno just trying to figure out why you wanted 3.. realize you have another.. they are very low end subs.. for 200+$ you could probably do better though.. hell my 18"btl was only 300 shipped
