This kit includes the module, the electronic parts and the speaker.
Neither the cabinet nor the plates necessary to assemble a cabinet are included.
This kit allows you to mount your own LeSUB HCFR, an active subwoofer designed and developed by the HCFR community.
It includes the amplification module, both speakers, wiring with full dressing and all the necessary connectors for its assembly.
Just mount the whole device inside a cabinet and you will end with a high-performance sub box. The kit is designed for isobaric charged bass-reflex mounting in a cubic housing that respects the Hi-Fi standards.
A flat box installation is also possible for a home theater-oriented integration, this format will fit elegantly into an audio / video installation ambitious.
LeSUB HCFR operates with a DSP-ICE250 PWR amp module used in bridge mode. In this configuration, the module is able to develop tremendous power with excellent SNR rating (121dB)..
The MiniDSP PWR-ICE250 embeds an integrated DSD (Proc SigmaDSP Analog Devices ADAU1445 28 / 56bit, 172MHz) ensuring excellent signal processing capability / digital filtering.
This amplifier / DSP is equipped with balanced analogue inputs (XLR) and unbalanced (RCA). Furthermore it is possible to use the I2S input / output. This broad connectivity allows leSUB HCFR to join almost any audio systems.
LeSub HCFR integrates two Low Profile subwoofer speakers 12 "Dual ceramic ferrite coil. This model benefits from an ideal 10mm excursion for deep punchy bass while allowing fixtures optimized in terms of space.
This model measures a sensitivity of 88dB 2.83V / 1m with a frequency response of 28 to 300Hz (put into perspective with the upstream DSP configuration) to a resonant frequency of 33.7Hz. These characteristics make it an ideal candidate for sound to a living room of reasonable size with enough reserve power for more ambitious listening rooms.
The plans and dimensions of the box have already been worked by members HCFR. The DIYeurs who wish to work on a project speaker / sub bypassing the package design box will be able to simply follow the plans made available by the community :
You are of course free to define yourself on the type of housing that best suits your needs. Moreover, electronics and loudspeakers used can accommodate different arrangements and different shapes, so you can follow the HCFR plan to the letter, use as a base to customize.
This kit includes the module, the electronic parts and the speaker.
