Morel Enclosures by Size and Configuration
Every cabinet is a sealed down-fire build cut to one specific Ultimo model, across both the slim and reference lines. Match the model on the product page.
| Size | Configurations | Lines covered | Build |
|---|---|---|---|
| 10 inch | Single and dual | Slim and reference | 1.5 in double baffle |
| 12 inch | Single and dual | Slim and reference | 1.5 in double baffle |
Shared across every row: Langboard Elite MDF cut on ShopSabre routers in Tullahoma, Tennessee. Plush black carpet. A Proline X ABS and carbon fibre composite terminal cup with stainless hardware, pre-wired in 12-gauge OFC. Construction method varies by series and is stated on each product page.
Slim and Reference Are Not the Same Driver
Morel offers both an explicitly slim-format Ultimo and a reference Ultimo at these diameters. Their parameters and their mounting depths differ, so the cabinets do too. The model number on the driver is what decides which enclosure you need.
We Cut the Box, You Source the Driver
We do not sell Morel drivers and we do not represent the brand. Every cabinet here is built to the figures Morel publishes for a subwoofer you already own or buy elsewhere.
Performance Optimized Series
The build standard across the Morel range: a 1.5 inch double baffle cut to one driver's published alignment.
Cut to one driver
Slim-line cabinets
Cut for the slim-format Ultimo, which exists because the install would not take a standard-depth driver in the first place.
Sealed
Reference-line cabinets
Cut for the reference Ultimo, where the driver is the centrepiece and the cabinet has to stay out of its way.
Sealed
Baffle thickness and construction method vary by series. Each product page states how that cabinet is built and which Morel model it was cut for.

Which Morel subwoofers do these boxes fit?
The cabinets here are cut for Morel Ultimo subwoofers in ten and twelve inch, covering both the slim-format line and the reference line. Each product page names the exact model it was designed around, and that is the match to work from rather than the diameter.
Do you sell Morel subwoofers?
No. We build the enclosure, cut to the parameters Morel publishes, and you source the driver. We do not sell Morel drivers or represent the brand.
Can I use a slim Ultimo in a box cut for the reference model?
You should not. The two have different published parameters and different mounting depths even at the same stated diameter, so the cabinets differ in volume and in the baffle. Using the wrong one gives up the performance the driver is capable of and can cause a clearance problem.
Why are these all down-fire?
Because the orientation suits both Ultimo lines: it aims the cone at the floor so the floor becomes part of the acoustic load, and it keeps the cone where cargo cannot reach it. The clearance is designed in, on feet that set the gap rather than leaving it to the carpet.
Are these sealed or ported?
All sealed, and every one ships with polyfill already installed. A sealed alignment suits these drivers and preserves the control they are chosen for.
Can you cut a Morel enclosure in a size you do not list?
Possibly. Everything is CNC-cut to order in Tullahoma, Tennessee. Contact us with the exact Ultimo model and the space you have and we will tell you whether we can build it.
