Hi All,
I'm planning to make a small sub that sits below my TV as part of a 2.1 type arrangement.
The external dimensions of the sub are somewhat set by the size of the room and the placement of the TV within the room.
I have a 10" driver and plan to make the sub active with a TDA7293 based amp and an active low pass filter.
The cabinet will be 18mm birch ply and the ballpark volume is about 44 liters (not including the driver and electronics)
The driver is this one: https://cpc.farnell.com/mcm-audio-select/55-2981/speaker-10-die-cast/dp/LS04704
I was planning to front load the driver.
Is this a feasible plan and are there any design considerations or comments from members of the forum?
Many thanks in anticipation.

What are your plans? Music, HT?
Closed or ported?
Little unknown driver. Datasheet doesn't give enough parameters for a SIM.

The source material is mostly TV based, movies, then music. Because the amplifier is not very big (100W) I was thinking of a closed design. I can change the driver if it's not the right one.
The Qts = 0,54 sure fits a closed box.
For music you don't really need the range below 40-50 Hz, but for HT you will like to have the lower range. Will be hard to reach that low with a closed box.
With a port you can pump up the lows, but needs the volume to get real low.

Okay, it's not really a subwoofer driver. However, if that's the budget you're wanting to go with, I'd consider these: https://cpc.farnell.com/unbranded/55-1455/dual-coil-woofer-8/dp/LS00415
I used a pair of them when I was starting out, and the results were decent for the money.
