Yes, but 1200W is a must for better dynamic headroom in the bass region. That said, both UcD400 and DS4.0 sub-amp is enough for most subwoofers out there. I managed to almost destroy a SEAS L26ROY driver in a 40 litre cabinet with passive radiator using a Hypex DS4.0. 400W is plenty - to some degree 🙂)

dimensions ?
Hi Bruno,
what are the dimensions of the nc400 and the smps ?
no need to be accurate. I understand if you'd rather wait till the final released versions.
I only ask as I'd like to source an enclosure, but don't want to get something too small.
Fantastic work, thanks so very much for making a DIY version !
I look forward to building a pair of these amps. i assume the smps is for a mono-block.
please take your time to get everything right, I'm happy to wait for any extra month or two. Will give me more time to same some money. (we'll see if i need to use euro's or dollars or francs or .....)

(i'm not sure if i should get a new pre-amp too, the one i have is not balanced. I have seen the musical fidelity a1-bpa being sold off in the uk. )

I suppose nc400 (400 watts) will be the minimum of the series? There wont be any 180 version like ucd to people that wanna go active multi-way?
400 watts for my tweeters is way too much 😉

Your woofer excursions, thermal power handling, and frequency dependant sensitivity are your determinants of bass headroom, unless you're chasing flatness to 5hz with .8 Q sealed subs. At VLF your best bet is to throw more surface area at the problem, not more heat.
I run a sub with a linkwitz transform and some additional EQ.
After that it's barely 15dB headroom. And I need that. 😛
no but i have really power hungry speakers.
the ucd700 is the minimum but they are happier with ucd2k.
I guess ackcheng's point was that for a sub a ucd2k might be the better choice, as you don't really need the ncore technology in a sub.
yes and i answered him that i want them for speakers not subs.
it may seems insane that speakers need that much power but they do.
not 2kw but 1kw to give the maximum they can.
