I have a pair of volt 4504's (the non-horn loaded ones.) Currently loaded into a 180l or thereabouts ported box. Effectively the Volt recommended design. And they sound very nice. However, I keep wondering if there was a design that could squeeze a few more dB's out of them. I know a bigger box would be one way. But I'm interested in maybe trying in a cube-type design. Or can anyone suggest anything else?

Actually, if you were willing to give up a bit of LF extension, the smaller, higher tuned suggested designs from Volt do give a little more SPL.
That's in part because tuning higher gives more reinforcement further up into the passband, and because it also helps suppress excess excursion in the passband, allowing you to use slightly more power.

Herewith the 3 suggestions from Volt, all driven to Xmax in band with a 100Hz, 24dB Butterworth crossover:

Thanks Dmorrison, that's very kind of you. It is quite an increase if I lose a few hz off the bottom end with a smaller cab. Could be worth a try. Rather hoping that another pair of drivers will pop up for as good a price as my existing ones, could be a long wait though! Cheers.
