Dtqwt

[kingfisher]

First time posting. Have been registered for some time and using the forum to search for answers. Been a good resource! I do have questions now. I'm building a pair of DTQWT cabinets and will be using a pr of JBL 2152H as the front mains. I am looking for suggested woofers for the rear panel to shore-up the low end. Any tried and proven woofers in the 12" variety, maybe?

Thanks neskor
I've contacted Troels on this and was given direction on where to look for help designing the cabinet structure! I, however, was looking for help in sourcing woofers, mainly JBL, in a character sound type suggestion! I may look to the Pro-audio scene for drivers also!

It looks as though more information is in order here! The problem I face is in the spl of the jbl 2152H listed at 102dB. I figure I would need a single woofer with a matching 102dB or 2 woofers with a combined spl of 102dB! Given this data I do not wish to place any resistors in the path of the 2152H and choose to match the output with efficient woofers!

OK, I've got to ask; what does DTQWT stand for?
