Tune enclosure to 16hz, should be crazy.
I never said ported was bad, or low dynamic range high distortion things. I just said horns were more dynamic and less distortion within designed bandwidth intentions. Different. I like ported. I've said all along that ported is my backup plan if I fail with my horn experimentation.
Actually I'll go a step further and throw you a major compliment. Of all the systems I've ever seen here on AVS if I could choose just one for myself it would be yours. Please don't think I have some disrespect for ported
I generally like them a lot. For good output and extension it's almost always a solid choice.
But horns do have advantages in output, dynamic range, efficiency, and suppression of distortion compared to ported and a well designed horn is louder, more dynamic, and cleaner sounding within it's designed bandwidth than a well executed and designed ported subwoofer. Ported sound best within the octave of tune but typically this is lower and so in the upper bass and mid bass a horn sounds cleaner and has lower distortion often by design, that's not necessarily a problem with ported as much as it's a benefit of a horn.
But if I look at your system in my situation a few things jump out at me that worry me that probably would not if I was you in your situation.
First, I can't do (8) LMS at $993 each, nor can I afford the amplification you have either. So lets just cut the amount of subs in half, the amount of amps in half, and for good measure lets cut the price of the subs also in half, same with the amps/power. Ok perhaps I could swing 50% of your watts, 50% of your drivers, and 25% of your budget spent. Now my space is a bigger - so that is lost output. And- that means I'll be pushing cheaper amps and cheaper drivers harder using half the amps and half the drivers to achieve the same level of sound in a bigger space. Doing this means I'll likely distress the drivers more than you do, introducing mild distortion at times of high output, and I'll be stressing lesser amps and heating them up more also introducing slightly more distortion, and I won't have the headroom and dynamic range you do with all those drivers and watts and my bass will compress sooner and at a lower SPL than yours.
It's still "enough" though. But I'm just wondering can I do better for $2000 in drivers? If I can't I'll end up porting some subwoofers.
