Default ~50W Class-T Amp with tone control?

Hi there,

I've got some old Beovox CX-50 loudspeakers that I'd like to use in the basement when doing sports.
Since their quality is not that good I thought I'll go for a cheap Class-T Amp.
I tried the Lepai TA2020+ I have in my car and it's almost enough power (although they are rated 50w/6 Ohm).

I thought about a TDA7492, 2x50W but I can't find any with tone control (probably need to increase bass with these small speakers).

Does anyone have a suggestion for me? Alternatives are the "Mohr SV 50" or SMSL SA 50. I need a finished built as I'm a noob

Thanks for your help,
Christoph

Thanks for the hint!

How does the TPA3116 compare to for example the TDA7492 or other Tripaths?

Thanks! Better than the Tripath 7492 or 2020?

I saw some TPA3116 with bluetooth, this might be useful in the car... from nobsound.

In general...
- TPA3116 usually sounds better than the TDA7nnn amps. Some boards sound good in OEM state, others "require" modding.
- 2.0 speaker output boards sound better than the 2.1 output boards.

Having written that, someone pointed me at this youtube: -

There is also a TPA3116 version of the board he uses for a few $s more.

Thanks a lot

As I don't have any experience, which oem boards of the 3116 with Bluetooth and bass control are suggested? There are so many brands.

Is it only available in 50w or lower as well? For the car I would only need a 20w amp.
