I know not all of you guys visit some of the other forums, so I figured I'd post this here too. Straight copy and paste from the other forum. In case you don't go through the threads I link, the power is a DD M2b @ .5 for both subs in my CRX. And the whole premise to this test was somebody was talking shit about how the Z would rape a little HD on the lows.
Let me first just say thanks to Murph and Jacob for being cool about this test. Neither had anything to do with it. It was all me. And actually... Murphy HATES comparison tests like this. He was quite uninterested in the whole thing.
Speaking of comparisons... I know it's inevitable that this will be viewed as a "head to head" or a comparison or whatever- but I'd like to think of it as more of a showcase of a couple bad *** subs. So... keep that in mind.
In case you're just joining us... these two threads should catch you up...

Now, some of you may notice a distinct lack of videos in this thread. Well... I videoing EVERYthing at first. But after about 20 minutes of vid on my phone, I thought to myself, "Why am I videoing all of this?" And I realized it was for "proof" of the results. I came to the realization that I'd never, ever get enough video to satisfy everyone about everything so I said **** on it. I think I've earned the right not to have to spoon feed y'all "evidence" of my results. If you want to write this test off because of the lack of video, I will understand. Doesn't make it any less valid or true. There was just entirely too much of it anyway.
Ok. That's enough of that. On to the results...
TSP's as tested...
Sundown Zv.4 10" Dual 1 ohm
- Fs - 33hz
Sensitivity - 81db
Tantric HD10 Dual 1 ohm
- Fs- 42hz
-Qts - .58
Round 1 - Slap some **** together.
Box - 1.8 @ 31hz. Why 1.8 @ 31? Because MDF remnant and full length 4" aero while waiting on the FedEx guy to deliver the Z. That's why.
Predicted response. You can see here the Z has a distinct advantage in this alignment.
Z- 141.5db @ 30hz
HD- 140db @ 30hz
Z- 145.5 @ 32
HD - 144.2 @ 32
Musical peak (same song).
Z- 145db @ 32
HD- 142.7 @ 32
The Z started pulling away from the HD on music in this box. This was a full tilt run on a pretty brutal song. This isn't an average. It's just a peak score on music.
Round 2- The burp warrior.
Box - SPL cubic feet tuned to loud. This is the box I use to test every **** 12" that comes through the shop. It's probably got over 100 burps on it. Even though it's for a 12", it's the only thing I had handy.
Predicted response - N/A
Z- 151.9db @ CRX
HD - 150.4 @ one cycle lower than the Z.
The peak frequency difference is most likely due to the added displacement of the Z. Full disclosure noob moment- I completely forgot that the CRX is setup for daily and that I'm crossed at the HU lower than the peak frequencies here. These scores could have been much higher.
Round 3- TaylorFail.
I've been wanting to try something with a tube enclosure so I decided, "why not?" I fabbed it up all ghetto and what not (like I do).
Tube failure. The wood to tube joints got blown out. I didn't even record the scores. I know... I'm lame. Fwiw... I did actually try both in it in case the first sub just didn't "like" the tube. The Z was louder.
