Hello All, Looking for some suggestions for a sub cab, maybe a 1 x 18, but one thats compactly constructed. Actually, the speaker size doesnt have to be an 18 .... as long as it handles low freq real well at 500w or higher without a hint of struggle. If any of you guys have experienced using one or seen one, pls let me know what any info you have on it. I saw one at a show once, it was an 18", roughly 24"x18x24" dimension. It wouldve been perfect, but couldnt tell what brand it was and didnt get a chance to talk to the owner. Your suggestions will be much appreciated. If you have one for sale, let me know too. Thanks.
