I had a lot of questions about the performance I could expect. I already know this is one of the baddest drivers on the planet. I've read everyone's reviews, the DIYers and commercially bought, the show reports and so I'm well aware of its performance, how dominant it can be, but, what will this do for me. How would this feel, sound, add to or subtract from the performance?
Like always, when I get close to the end, all heck breaks loose and I’m full on head first. How many of us are 95 percent done with our rooms and will always be 95 percent done. I want instant gratification. Nevermind that its takes months to fine tune picture and sound, I expected to plug it in, throw the switch and Bam, perfect bass. Nope. No sound from the sub. So I go through the process to remedy this, the amp’s second channel was unplugged, the second sub in the prepro was off and so down the line. I was highly stressed. Its late Saturday morning, I’m having a GTG and I’m insisting on cooking and still had number of things to do. Point is its less than an ideal day to test drive the new sub. I don’t recommend it. My thought was I’m fine with the front subs, their extremely tactile now and the Crowson’s will mop up whats left. I’ll leave it off and mess with it later. Can’t see it anyway.
Ding ding. One of my friends sends the infamous Back to the Future pic. Seems my son was at his house and bragged about the 24. Great. Back in the room. Ok, you know what? I’m gonna let Audyssey do its thing and hopefully get me close enough and I'll do the rest after. Audyssey has never let me down.
Audyssey let me down. At this point MiniDSP was in pass thru mode. Trying to set levels by ear proved difficult. Audy was worse. Trying to match gain at the start of Audyssey setup was impossible. One click on the amps rotary gain knob raised the volume from too low at 69db to 91db. One click. Something's wrong here. I ended up using the tone knob as a fine gain. That's what it works like. I finally got both subs balanced, though it was all front, no rear. While that was expected, 6 voice coils vs 1, I didn't expect the sound to be so different when compared to all previous sub configs. With both sub 1 & 2 in the green/75db range Audyssey finished and errored out, no subwoofer 2. Tried it 2 more times, same result. So I cranked sub 2, the 24 up to 92 db. Now it recognized sub 2, with a 17db advantage then added another 8db. Frankly it sounded like garbage. I checked distances and fronts were 16ft. They are 10ft and prior to moving the new sub in, Audy always set the front subs to 10ft.
The new sub, physically about 3ft, maybe a little less, was set to 43ft. I've never had this happen in the hundreds of Audy room corrections setups run. It's like the little minions inside Audy saying, " it looks like a sub, it's shaped like one but we don't have a clue what it is". Which should have been a sign on what was to come. I moved on to Omnimic. Here I was turning knobs up and down in a frenzy trying desperately to find a workable solution. I set the distances to physical distance and set sub gains to match at the peak and set sub 1&2 to -12db. Now it sounded right or in the ballpark at least.
After 2 hours wasted, demo time with Kong. I bounce around the disc while raising the volume thinking is this thing gonna boogie or what. Then Kong fists Jackson. And me. I got drilled. Caught flush. I’m not talking about the heavy pressurized feeling I get with the 18’s. The diving in the pool or popping the ears. No. This is getting punched in the nose! Much different than the hair tingling, pants flapping. But I have never felt the skin ripple thru my body. These sensations are easily explained scientifically. Having the sheer power to pull this off is another thing all together. This is what all you owners of the 24’s have been describing. Now I understand. It stunned me. My response was what just happened. Its takes about 3 to 4 shots to comprehend whats going on. It's speed, agility and tonality is shocking. Its crushing tactile but by way of a dynamic swing so large and quick that your left wondering what just happened. Whats dumbfounding is the scale of this thing. I’m use to x amount of SPL produces x amount of TR, PR
, etc. You can move the lines and ratios up and down various ways but they pretty much sound and perform as expected. Adding the Crowson really took mine up a notch. Then this 800lb Gorilla comes in, I unchain this bad boy and say do your worst big fella and it obliterates what I’ve had to date. Juggernaut is fitting. I’ve had 8x18’s nearfield in the past and theres no comparison. Theres more at play here that I need to figure out than just matching SPL.
Lastly is near field performance. If my 18’s are a shovel then this driver is the earthmover at the beginning of Avatar. It moved my seats forward an inch. Its effortless like Vince and dc mentioned above. Even with little cone travel it makes a big impression. Everything is near field with this sub. This is a UberSub. I’ve only watched the Guardians 2 and parts of Kong so I can’t comment on anything else but we’re off to good start.
