Question 1

Can two LD Systems CURV 500 TS subwoofers be used connected in link with an FBT speaker instead of the original satellites?

Accepted Answer

No, it is not recommended to replace the original satellites of the LD Systems CURV 500 TS with a third-party FBT speaker, and here’s why. The CURV 500 TS system is designed as an integrated set where the subwoofer contains the Class D amplifier and the DSP processor that manages signal distribution, frequency allocation, and multiband protection.

Connector and power incompatibility: The satellite outputs of the subwoofer are Speakon connectors specifically designed to power the CURV 500 satellites. A generic FBT speaker likely does not have a compatible Speakon connector, and the required impedance (16 Ohm for standard satellites, 8 Ohm for duplex) must match exactly. The subwoofer allocates 300W RMS out of the total 1,000W for the satellites, a power optimized for CURV 500 satellites only.

Loss of DSP optimization: The CURV 500 TS includes 6 DSP presets specifically calibrated for 1, 2, 3, or 4 CURV 500 satellites, with tailored equalization and level management. The DSP processor will not be able to optimize the sound with a third-party speaker, resulting in poor frequency distribution and sound imbalance.

Regarding two subwoofers in link: The CURV 500 TS is a standalone system without an option for subwoofer expansion like the ES/SE models. Only the ES (Entertainer Set) and SE (Subwoofer Expansion) variants can be linked via a dedicated 5-pin XLR cable to form a stereo system with two subwoofers.

Recommendation: To maintain the integrity of your CURV 500 TS, exclusively use the original satellites (standard or duplex) provided with the system. If you need a different setup, consult LD Systems to explore compatible options or consider another system suited to your specific needs.

Question 2

Can the LD Systems CURV 500 TS subwoofer be used with an external speaker instead of the original satellites?

Accepted Answer

Yes, it is possible to use the LD Systems CURV 500 TS subwoofer with an external speaker connected in place of the original satellites. However, it is important to consider several factors to ensure optimal and safe use:

Impedance compatibility: Make sure that the impedance of the external speaker matches the specifications of the system to avoid any risk of overload or damage.
Power handling: The external speaker must be able to handle the power delivered by the subwoofer without distortion or risk of deterioration.
Sound quality: Replacing the original satellites may affect the overall sound quality. It is advisable to test the system to ensure that the output meets your expectations.

In summary, this configuration is possible but requires careful checking of the technical specifications of the external speaker. This will ensure good performance and the durability of your audio system.
