mini speaker with D-class ampli

[argouno]

Hello Everyone, I have just joined this wonderful forum, I'm Following some time, because I find it very interesting and complete.

I'm venturing into the construction of a small portable powered speaker with 4 full band 1.8 "of the k-tone for the upper middle section, and a driver TB Speakers, for the low.
I would like to ask if any of you have already experienced some solution of this type.
I'm trying to identify the amplifiers to be used (1 stereo for mid high + 1 for the mid low).

I would use the amplifiers d-class because they are compact and do not use heat sinks, dispose of lithium battery pack from about 12V and 4.5A which reaches a minimum voltage of 8.5V before intervening guards, and that I would have at least 4-5 hours of music, which amplifier modules would you use?

I tried to watch Pam8610, but have a minimum voltage of 9V .... what do you think of the TPA3110 ?? also they work to 8V and for me would be fine, but just do not know them .... help !!! ;-))

Thank you


Enrico

TPA3110 filterless board from sure-hifi sounds great.
I built one into an active speaker.

I do not miss the PAM8610 i gave to a friend a while back.

All chips from the TPA311x-series should work with a min of 5V.

I think I will try PAM 8610, I need a little power, and I found a form that uses two of these chips to get 2x10W + 1x 20W ..... I would say that for me would be fine.

thanks for the help
