You should build a test box also just to try them in the ideal enclosure size to compare the difference. Stoked for this review.
Morel Ultimo 12 - Review and Test Data
Hey folks,
As promised I am going to make a separate review on the set of Morel Ultimo Ti 12-2 subwoofers that I am fortunate enough to trial in my truck for the next couple of weeks. A big thank you to @clange2485 and @Nemesis87 for lending me the gear to make this happen. They have always been a sub I wanted to try out and I am lucky enough to spend some time with them.

I currently run a pair of Audiofrog GB12s.
![Product Rectangle Gas Technology Circle]()
Test enclosure:
2.5 CF net total, 1.25 CF each chamber
Fully treated with Resonix CLD
Polyfill @ (0.8/lb per CF)
Power:
750 Watts @ 2 ohm each sub from Mosconi Pro 5/30s. (Yes, I know everyone says they gobble up power but this should still provide me a flavor of their potential)
Testing I intend to try:
I will be posting up some measurements today/tomorrow.
This post is to focus on a review of the Ultimo 12, not necessarily a comparison to the GB12. Only comparisons I intend to review are measuring the subs against each other on equal power - aside from that, my focus is providing my subjective thoughts on the Ultimo as an SQ subwoofer.
Shoot me any questions or requests you have for this review. Looking forward to dropping them in later today.

Testing I intend to try:
- Replace both GB12s with both Ultimo 12s in isolated chambers - most of my time with them will be spent like this
- Run 1 GB12 in one chamber and one Ultimo 12 in another chamber - A/B test them with my DSP toggling each channel
- Drill out center brace in my sub enclosure to create common chamber and run a single Ultimo 12 - I believe this will allow the Ultimo to really show its low end capabilities.

You didn't ask but I can't help myself...
1st if you do decide to drill the brace then the Ti12 has 73 Square inches of Sd so you need, at a minimum 3 x 2" holes and I personally would like to see at least 4 or more to make sure there's no compression between chambers.
Model Comparison... you knew it was coming.
Transfer Function:
Green = GB12 (0.836 Qtc)
Red = Ti12 in 7.658 CuFt (0.703 Qtc)
Yellow = Ti12 in 1.25 CuFt (1.110 Qtc)
Teal = Ti12 in 3.340 Cuft (0.836 Qtc) - same alignment as the GB12
Straight to SPL prediction (excursion will take longer to explain) all on 750W - so the expectation will be that the Ti12 should be noticeably louder and even in 1.25 cuft the extension is better - drilled out or test enclosure and the extension really jumps out there...
Excursion Plots (for those of you that got past TLDR)
So even in the 1.25 cuft Hi-Q enclosure WinISD is predicting that you will be able to exceed xmax with 750 Watts so the "hopefully" expectation is that you will be able to tell whether the spider is limiting the cone more than WinISD is predicting or if you are able to exceed xmax and how audible the distortion becomes especially in the bottom octaves where the enclosure is also contributing to limiting the excursion.
Well won't have a ton to offer on feedback yet but we had a little subwoofer showcase today with @Nemesis87 and @teh_squirrel before I dropped the Ultimos into my box.

Then got the Morels dropped in - they were an easy fit as they are a slightly smaller diameter than the GB 12s. They are gorgeous subs.

So the suspension is still stiff obviously being new so I expect output to drop slightly over the next week (but also expect sub 30hz to become more potent) but this GB12 vs Ultimo on equal power....

Even if they lose 3db from break in, I am not sure I see the need for adding boat load of power to these things. My 5/30s are still on minimum gain as well.
This is what they look like on my current tune cross electrically at 65, acoustically at 50.

I won't offer up much more than that for now. Only have about 20 minutes with them but they sound excellent so far. Extremely subtle differences.
More to come.
We had a blast messing around with Max in the other vehicles.
