Why do you say you're leaving a few Hz and a little SPL on the table?
Any particular DSP you'd recommend over the minidsp (if that's the reason for question 2)?
In this application, I HAVE to be good to at least to 16Hz.
Since the cabinet is unchanged, more SPL means more power handling, which means a bigger coil and more throw. Right out of the gate, the SWS starts with nearly as much linear throw as the CVX, and has more than ample mechanical clearances too, though not quite equal to the CVX. The next step up would be the Stereo Integrity 15, they have a lot of throw, and plenty of mechanical clearance, but they're limited on the power they'll take, which is why I suggest the SWS to start with, cause they both end up making about the same amount of noise. Both of these drivers are a great fit with a 600 watt/channel amp, which is generally the second tier model in most pro amp lines.
If you need more? You get what you pay for - but you're stepping up to the $300/driver range. You're also heading into uncharted territory, as most folks are building with the SWS and SI drivers now, I'm not aware of anyone using the Fi Q or Sundown, and I'm concerned that the larger drivers may not even fit into the horn's mouth. I have not tested either, and have no direct experience with either.
I'm running a MicroWrecker currently, it is the littler brother to the LilWrecker. It is -3 dB at 18 Hz if I recall. Due to the limitations of the integrated DSP in my iNuke 3000DSP, I am highpassing at 20 Hz. That means that 18 Hz is now down more like 7 or 8 dB versus 3 dB, because my highpass is -3 dB at 20. The 20 Hz limit on the highpass (without the added filters trick that I can't seem to get to work) has cost me several dBs and several Hz of extension at the low corner.
My current situation is very temporary, so this is fine for me for now. For me, it really isn't worth fussing over at the moment. Sure, I could plug in my MiniDSP and set it up to get a proper highpass, and I could use my MatchBox II to get my signal levels where they need to be, but that stuff is all packed away in boxes somewhere. That will all happen when I set up the new theater. If things go to plan, I'll probably conjure up some more proper subs and speakers too. For now, what I have works well enough. Yeah, there are a lot of things I would like to change, but until the new house is finished, this is what I have to work with, and my money is all prioritized elsewhere.
I really like the MiniDSP. Not much can do what it does for the cost. Sure, it has its limits. Know, understand, and respect those limits and things should be fine.
According to the measurements I have, the LilWrecker is -3 dB at about 14 to 15 Hz, so if you can't get 16 Hz, it's not the sub's fault.
