Hi all,
I have builded a small boom box with two full band small speakers from dynaudio, but I am not satisfied. The bass response is bad.
I was thinking: would it be possible to use just one wooofer and two tweeters for another stereo boom box Design?
I would need two crossovers, but my question is how can I connect the low frequencies in mono?

Hi, would you be more precise? The pair of tweeters you are referring to, are in reality two fullrange, like the ones you are using now, right? The design can accomodate a dual coil (sub-) woofer for easyness. Or even two ( single coil) 😗
WHat you need is something like two 5 to 10 mH coils and...wait, how much is the power ? usually the full range drivers are not high-passed ...look for crossover (passive) for subs, might come for cheap.
On the acoustic side...well, the best (optimal) would be: all pieces should be detatched from each other and aiming at the listener, this one's easy as a boom box is small but conflicts with rule 1 as is overly integrated, as it does not allow the separation of L and R speakers.

Thanks for the reply.
I meant instead of the full band speakers, using a single woofer for the low and two tweeters for the high ( for the stereo).

A 3-channel (dedicated) amp is best.
Left full, right full, (or filtered highs only) and blended center bass only.

The problem is not to have filtered highs, but filtered midbass ( and high freq...) because the body of the sound is there.
Of course someone will span ( and...pan) from 1 speaker for all ( classic cheap but powerful BT boombox) then allow blending between the two channels up to certain frequencies where separation becomes necessary for ecolocalization 🤐
The context would allow for that but it doesn't meet some criteria

2.1 amp, subwoofer and two fullrangers is what you want. You can build it all in a single box with 3 chambers, 1 for sub and two for fullrangers. The amp already has a frequency knob to tune the sub and the fullrangers can be highpassed with 1st order filter (bipolar caps should work just fine). You can get a tpa3116d2 2.1 amp for about 20-30 bucks
I put this one together to keep me company at work

There are lots of options with this. As previously mentioned a TPA311D2 is probably the best way to go. It will yield about 30 watts from 12v. Boom-boxes are generally about efficiency so a CLASS D amp is a good start. Another general rule-of-thumb is that bigger drivers make more noise using less watts.
A 5" woofer (not subwoofer) and a couple of mylar tweeters should do the job.
