There are several relative terms in this sentence. More punch that what? More bass than what? More sensitivity than what?
More than my current speakers
Some, maybe many, studio monitors (and powered passives too) boost bass and have a sub-bass roll-off. So not only do most actives play louder than equivalent passives with the same amplifier power (partly due to actives not having a power-sapping, dynamics-limiting passive crossover) they often have a stronger, deeper bass than equivalent passives. You yourself named one - the KRK Rokit RP5. This particular speaker surely meets all your requirements - and you don't have to concern yourself with sensitivity. The latest generation have fancy EQ controls to play around with too. From audio clips I've heard on the Internet, the tonal balance of the KRK sounds more like a stereotypical passive hifi speaker than most active monitors. The Mackie MR5 is also reported to have a strong bass.
The lastes version are not that good
Yes, yes and not usually. I am aware that users of
some of the cheaper active monitors have reported hiss and I can appreciate that sitting close to a hissing speaker would irritate, but I use cheap active monitors and there is barely any hiss. I have to get within a few inches of the tweeter to hear any hiss. I've heard a few other cheap actives that didn't hiss either. In general, there's no more hiss than a budget amp + passive speaker pairing.
Theres not hiss at all using passive spakers and a amp
What's this about a control unit? If you had passive speakers you'd need to use an amp so do I take it that you already have an amp you wish to deploy? If not, capable cheap switch boxes with a volume control are available:

I would like to keep it, can change it with my all in one nad system i use for my tv and sell that, non of them have preout for a power amp or active speakers (was there a link to something ? embedded media ?)
Guess you would need a phono amp stage too, unless your turntable has one built-in.
I have what i need for my turntable, no problem when buying active speakers, what i need is a control unit for my tape deck,turntable and out put from my dac transporter and pc)
You mention the M-Audio BX8 D3 as a possible option. Really? Do you realise just how large this speaker is? Why not determine the maximum size of speaker that you would accept on the desktop - try to visualise a pair of M-Audio BX8 D3 sitting on the desk. Are they too large or an acceptable size? If they're acceptable, you will be able to afford a few similarly sized designs that have big, extended bass. If they're too large, as I suspect, then you've instantly narrowed down your options, allowing you to better focus on your requirements.
Yes i did, as the behringer, they don't cost to much, they have more than enough power (spl) and deep bass so theres more deep bass at low levels and more clean power (spl) when it gets loud. M-Audio doesnt make an alternative that are bigger than the BX5 D3 and smaller than the BX8 D3. Would i miss adjustemts for the highs, that they have a smooth volume knob not one with indentation, do the amp has to much hiss,white noise ?
If buying active studio monitor 1/3 of my budget would go or a control unit, i have a tube buffer,preamp and a input selector but i think it's fare from good enough to use with something that has a studio sound, analytic,neutral,revealing,dynamic (bi amped,no passive crossover) + tubes, not my thing, also the volume knob is small, so it's not possible to adjust the volume in small increments do to the size difference of the volume knob and indentations on the tube buffer
