Product Usage Instructions

Choosing the Correct Enclosure

Enclosure selection depends on the environment, desired performance, power input, size of the vehicle, and preferred bass experience. The Ultimo Titanium series subwoofers are designed to work optimally in both sealed and ported enclosures, but each type will produce a slightly different sound result.

Sealed Enclosures

Sealed enclosures do not have any openings or vents. They provide accurate and tight bass reproduction with a smaller enclosure size.

Ported (Bass Reflex) Enclosures

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

Connecting the Ultimo Subwoofer

The Ultimo subwoofer can be connected in different configurations:

• Voice coil wired in parallel (1-3 woofers): 2 Load, 1 Load, 0.7 Load
• Voice coil wired in series (1-3 woofers): 8 Load, 4 Load, 2.7 Load
• Voice coil wired single (1-3 woofers): 2 Load, 1 Load, 0.7 Load

Tuning Recommendation

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 if the subwoofer enclosure is designed properly.
4. After listening to the subwoofer, you may choose to invert the phase. It is recommended to listen in both configurations to determine your preferred mode.
5. Before adjusting your sound system further, try moving the subwoofer enclosure to different locations in the car trunk. Placing the enclosure in different locations may provide the desired solution.

FAQ

Q: Can I use the Ultimo subwoofer in both sealed and ported enclosures?

A: Yes, the Ultimo subwoofer is designed to work optimally in both sealed and ported enclosures.

Q: How do I connect multiple Ultimo subwoofers?

A: You can wire the voice coils of multiple subwoofers in parallel or series, depending on your desired impedance load.

Q: Do I need an equalizer for the subwoofer?

A: If the subwoofer enclosure is designed properly, you do not need an electronic acoustic corrective filter like an equalizer.

Dear Customer,

• Thank you for selecting Morel’s Ultimo to satisfy your demanding car audio standards.
• 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 Ultimo represents an extraordinary combination of audiophile bass quality, high power handling and ease of installation.

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 series subwoofers are designed to work optimally in both ported and sealed enclosures however, each of these enclosure types 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 results, we highly suggest using 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 Titanium series to produce best results in both sealed and ported enclosures.

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 powerful obsorption inside the enclosure, and reduced transient response at lower frequencies. In conclusion, sealed enclosures provide powerful bass resproduction and excellent dynamics with extremely low distortion.

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.

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.
