A cabinet design for Lii Song Platinum 10 from Decware

It's a bit difficult to say, since the published specs. appear to be inconsistent with themselves. Qts can't be 0.175 if the Qe and Qm values are what they are stated to be, and I can't see how the published Vas is consistent with the stated suspension compliance, B*L, Sd, Mms, Fs etc. & visa versa either. I suppose it may also depend on what you call a smaller horn too as these things can get relative. ;)

Just taking the Qt, Fs & assuming they're accurate (with the above caveat in mind & without attempting to recalculate), then with a voltage source amplifier you've a mass-corner of 526Hz, making it basically a midrange horn driver -that Q as-is is way too low for bass-horn loading as-is, since as an ROT, 250Hz - 300Hz is about the upper limit if you want to keep GD reasonable. In theory, you'd need ~6ohms of series R to just scrape the 300Hz, again with the above caveats about data inconsistency in mind, so YMMV. If we stick with all those assumptions, then in theory yes, if you're OK with potentially limited LF extension or a slightly different load scheme.

Indeed, though with HR's help, here's the reconciled specs (assuming they're not complete 'flooby dust').......

BLH wise, absent any additional series resistance, Fhm = ~330 Hz = too much BSC unless in 2pi space, so 8 ohm matching impedance SET amp is the way to go to put them up against the wall (~1/2 size) and 16 ohm taps for corner placement (~1/4 size).
