Just sharing yet another project I designed for my brother-in-law this time
Basically it is about building two sealed cabinets (baltic birch plywood) with Markaudio CHN110 drivers and accompany them with a sealed DOS (dual opposed subwoofer) sub using 2x Beyma 8BR40/N drivers.
Here is how the front cabinets will look like:
They will each provide 85dB at 1m at 24Hz with 25W load (which is the xmax limited max load) --> 91dB for stereo + room gain
They will be cut at 80Hz where the max SPL will be 99+6 = 105dB
The DOS sub:
This one will provide 96dB at 24Hz at 1m + room gain (with 95W being the xmax limited max load)
This is his first speaker project so the aim was to keep the costs to a minimum
CHN110 costs 60 EUR each and the Beyma 70 EUR each so I guess we have managed to achieve that
The Markaudios will be driven by a Loxjie A30 amp (the 2x25W max required power at 8ohm shall be fine with this amp)
A Sabaj A20A in bridged mode will be connected to the sub out of the A30 driving the Beymas
I know that this way there will be no HPF to the fronts but that is a compromise that is fine for now - the upgrade path is to use a multichannel DAC (e.g. Universal Audio Volt 4) and connect the amps to it (fully independent 3 channels basically)
Source will be a PC with heavy DSP - initially based on REW but Dirac Live 3.X will be considered too as an upgrade path
Will post pictures and measurements as the project progresses
Stay tuned!
EDIT: pictures as per the below
