Those connecters look a little stressed and exposed to me. I would not be confident at all that they are best connected, especially with NACA5. Sorry to say. I would remake them with proper soldered sprung type bananas. Naim SA8’s made up by a competent dealer for the Nova end. I feel sure that this will sort your bass issues out, in fact the whole presentation as a whole will lift way beyond your expectations i feel.
Here’s how i do mine and they sound great!
Mike, I feel you are very often thinking on how upgrade your amp, adding another brand ( class d), subwoofer…or 250 dr.
I am aware that in NZ a 282/250 is very very expensive.
Why not a Townsend Allegri with a Nap 250 dr. No need for a ps to the Allegri, around 3k in UK.
Just thinking…
It is correct that the sub is connected at the speaker end, just like @Richard.Dane pointed out. However, your dealer has connected the sub to just one channel, so it will only be playing bass from that one channel.
What you need to do is split the insulation from the lead from the rel so that you can separate the three wires inside. Connect the red wire to the positive and the black wire to the negative on the right speaker. Connect the yellow wire to the positive on the left speaker. That will enable the sub to play bass from both channels and hopefully will make everything sound a lot better.
As HH suggests above, if you have no sub lead connection to the other speaker then you’ll only be getting bass from one channel.
These will complement the bass drivers for high frequency reproduction.
Have you checked the Powerline Lite plug is firmly seated in the decoupled power socket on the Nova?
Is this correct.Both woofers seem to work. If I power of One of the woofers I clearly hear only the connected and powered woofer. Maybe this only applies if you have one subwoofer , but I have two of the same
in holland we only use one sort of powercable. Powerlite and such things In general are of no use in Holland.
I assume it still has an IEC power socket on the Nova end though - I only ask as in the past when I tried a different power cable I had not realised it wasn’t in far enough until I moved furniture beside the Nova away and thought the plug was sticking out too far - the decoupled socket can be deceptive.
I’m not a subwoofer expert but would imagine it’s a good idea to feed both channels to each sub. The advantage of two subs is not to have one for left and one for right, but to integrate better with the room. I may be wrong though and would defer to someone who is more of a sub specialist.
Maybe that’s your problem. You have too much sub-woofer!
I suggest disconnecting both sub-woofers and spend a few days listening with none. Then connect them again. You will probably find that is when it all goes wrong.

I’d missed the 2 x sub-woofer part, thought you generally only needed one due to the very low bass being less directional?
Sorry, I forgot you had two. Have you tried optimising the sound with no subwoofers operating, as I and others have suggested. Integrating one sub is tricky, let alone two. It’s quality of bass you are after, not quantity. Maybe a pair of larger speakers and no subs would be easier to get right in your room. For what it’s worth, when I had an nSub and nSats, the sub was on the back wall, and it worked really well. Get the sound right without the sub, then add just one, connected to both speakers.
Nothing to be sorry for…you have been a great help so for and cannot thank you and other posters in this thread enough . But first it is not a bad idea to wait till tomorrow when I post results to make a few things clearer.
I get the impression your tests did not reveal a simple overall change that worked unequivocally, or that there is a lot of detail which may help others in the future.
You’ll be pleased to know that I am now settled with where I’m at. The Class D power amps were a useful test but didn’t really work out - greater drive, but with a reduction in imaging and the soundstage. The subwoofer is mainly for the low frequency sound effects with movies in the media room via the Nova.
Now, with more time to enjoy the SN2/HiCAP DR/NDX2//XPS DR main system, thoughts of a 282/250 have evaporated. The system sounds great. Yes there is always more, but I’ve only had the full set up for just over a year. Anything significantly better will be at quite a big cost and well into diminishing returns. I’m heading into part time work pre retirement, so time to enjoy what I have and focus on some other priorities.
Very good Mike. You have certainly taken the good choice, regards of the stratospheric prices of Naim in NZ.
I had the feeling that you were often thinking of upgrading your amps, but now know that I was wrong.
Enjoy sweetie.
I was thinking about that, but have decided now that I don’t need to!
The standard Naim 2 pin plugs dont fit the Uniti range atall they have their own smaller version, which is a bugger to solder yourself as they are not right angled.
Only the Unitiqute and Atom take the different plugs with closer spacing. Yes, they are quite tricky to solder.
