Default JBL K140 Enclosure Design??

Hey guys,
I have 4 Jbl K140 Professional Series Woofers(15") With a Pair of Jbl Professional Series Horns. I also have a Pioneer Reciever (solid State) pre amped to a Mcintosh MC2300 (2 x 300 Watts RMS @ .00001% THD) Very powerful and clean amplifier for those who don't know about it, it was $1500.00 back in the early 70's.
Now on to the question at hand, I need to know what would be a great enclosure for these woofers with the power at hand and the type of music I like to listen to...(Rock, and some Rap)

You ain't lying! I used one to drive a pair of modded Altec 210 theater midbass horns for a couple of decades till I had to sell off some stuff to keep the medical community wealthy.

Anyway, these are more midbass than LF drivers, so a good prosound alignment would be ~2.213 ft^3/53 Hz Fb. For Hi-Fi you'll have to trade efficiency for BW, so from ~4.25 - 10.63 ft^3/28 Hz Fb and boost as required to get the desired in-room response.

Or stick them in some JBL 4560 front horns to go 'live'.

Loud is Beautiful if it's Clean! As always though, the usual disclaimers apply to this post's contents.
