I just purchased a pair of speaker cabinets at a local pawn shop. Each contained a JBL D-140R 15 inch woofer and an le5/2 midrange. My questions pertain to the woofers. What does the R in D-140R stand for?Next, are these woofers usable in a home stereo application? I was thinking maybe a large bass reflex corner cabinet, a University Classic corner horn, a Pi cornerhorn or ????. I would really like to use these woofers as they are well made, in excellent condition and I got them cheap. However, I do not want to spend a lot of time and money building cabinets if they only perform well in a pro audio environment. I really would appreciate any information or opinions and offer my thanks in advance.

Thankyou, Andrew

You betcha. Those drivers can be used as they are, or you can recone them if you like.

That is good news! Now some more questions. I have no idea what the T/S parameters of the D-140R is, so I do not know what size/type of enclosure to put them in. I am open to any and all suggestions, however they do need to be placed in a corner. I have two really nice corners in an approximately 500 square foot living room. Got any ideas?
Thankyou,Andrew

The D140 T/S specs are similar to the JBL 2205, so you can use it in cabinets designed for JBL 2205. If you're interested, send me your E-Mail address and I'll send you some plans.

Vas 10.5ft3
Qms 5.0
Qes 0.22
Qts 0.21
Fs 30Hz
Sens 98dB/W/M
Max Power 150Wrms

You might want to confirm these specs though, as there are no JBL D140/E140/K140 recone kits available and so any repairs would have required a substitution or aftermarket kit.
