The subwoofer features dual 4-ohm voice coils, which can be wired to 2 ohm (parallel) or 8 ohm (series). Dual 2-ohm version is also available for 1 or 4 ohm loads.

What amplifier power should I pair with this sub?

An amplifier delivering 800–1200 Watts RMS at the chosen impedance is ideal.

Does the subwoofer require a break-in period?

Yes, a gentle break-in of 20–30 hours at moderate volume is recommended to loosen the suspension.

What is the mounting depth?

The mounting depth is 6.9 inches (175 mm). Make sure your enclosure has adequate clearance.

Can I use this subwoofer for home audio?

Yes, but it is designed for car audio. For home use, ensure you have a suitable enclosure and amplifier.

Introduction

Dear customer,

Thank you for choosing Morel's Ultimo subwoofer to satisfy your demandingcar audio standarts. The award winning Ultimo series was engineered with a combination of tight, controlled musicality and life-like deep bass reproduction.

Consistent with Morel's philosophy, this handcrafted subwoofer will satisfy those who like to "crank it up". The new Ultimo represents an extraordinary combination of audiophile bass quality, high power handling and ease of installation.

Technology features

Morel's Ultimo is the ultimate in subwoofer technological innovation and performance. Designed to perform as well in sealed or ported enclosures, the Ultimo's gigantic 5.1" (130mm) Hexatech™ voice coil delivers powerful,accurate,dynamic,and musical bass notes.

1. Octopus Grille

innovative design to provide protection and maintain acoustic transparency.

1. One piece Hybrid Cone

An integrated cone made from a composite of paper and carbon fiber for improved musicality.power handling and low distortion.

1. PFS ^TM

Progression field symmetry engineering for longer linear excursion and optimized performance at high power output.

1. Titanium Voice Coil Former (Ultimo Titanium)

Rigid and lightweight it provide a tonally balanced and accurate driver, with exceptionally fast transient response.

Choosing the correct enclosure

Enclosure selection depends both on the environment and on the desired performance. The power input and size of the vehicle play an important role in correctly installing the subwoofer, as does the preferred bass experience.

The Ultimo Titanium and Ultimo SC subwoofers are designed to work optimally in both ported and sealed enclosures however, each of these enclosure type will produce a slightly different sounding result.

As a rule of thumb, the bigger the enclosure, the lower the bass frequency response will be but it will have less control and definition. On the contrary, as the enclosure volume gets smaller, the bass frequency response is higher, but the bass reproduction is faster and tighter. For those of you who are looking to get optimal SQ result, we highly suggest to use sealed enclosures; for those who are seeking high SPL, we suggest using ported enclosures. The table below specifies the required volume range needed for the Ultimo series to produce best results in both sealed and ported enclosures.

Ported (Bass reflex) enclosures

Ported enclosures have a circular or rectangular tube or duct leading to an opening in the enclosure structure. If tuned properly, a ported enclosure enables greater bass extension from a smaller enclosure, as well as better power handling, efficiency, control and faster bass reproduction.

Sealed enclosures

These completely sealed enclosures are not affected by air pressure changes inside the enclosure due to cone movement. Acoustic suspension and cone movement linearity are improved, resulting in lower distortion and higher power levels. The drawbacks of the sealed enclosures are lower efficiency due to power absorption inside the enclosure, and reduced transient response at lower frequencies. In conclusion, sealed enclosures provide powerful bass reproduction and excellent dynamics with extremely low distortion.

Tuning recommendation

Once the proper enclosure has been constructed, please follow these tips to optimize the performance of your new Ultimo subwoofer. It is always suggested to consult your Authorized Morel Dealer for more specific guidance, if necessary.

1. Set your gain level control to ensure stable amplifier operation without distortion or saturation to prevent subwoofer damage.
2. Adjust the cut-off frequency according to the enclosure design and subwoofer specifications to ensure optimal performance.
3. Electronic acoustic corrective filters (e.g. equalizer) are not required, as long as the subwoofer enclosure is designed properly.
4. After listening to the subwoofer you may choose to invert the phase. doing so will affect the acoustic performance of the subwoofer. It is recommended to listen in both configurations in order to determine your preferred mode.
5. Before adjusting your sound system further, it is suggested to move the subwoofer enclosure to different locations in the car trunk. Placing the enclosure in different locations may provide the solution you seek.

Cone replacement procedure

The Ultimo Titanium subwoofer was designed using Morel's Trademark Accucenter™ technology, which enables easy, quick replacement of a damaged voice coil cone assembly by simply dismantling the magnet motor system and bolting it to a new chassis and cone assembly.
