Uniti2: PMC24/Ovator S400 in Edwardian Terraced Home Living Room?

Posted by: Marthinus Bester on 04 April 2016

Hi all

Time to upgrade my B&W 685 bookshelves which have served me well.  I'm trying to get rid of my REL Series 5 Sub so am keen to find floor standers.  Do anyone here have experience with these speakers in a similar environment? The room size is roughly 2.6x3.8x with a height of 2.8m.  Unfortunately Naim doesn't support room correction (yet) and am quite weary about having a boomy sound.  I'm renting and thus can do little in terms of acoustic treatment and at least one of the speakers will have to live right in a corner

The forum praises both speakers, and I hope it would match the Uniti2 & NAC A5 for some years. 

Q1:  Does anyone have experience with the same kit in a similar environment? The PMC24's are rated 90dB, 8Ohm and the Ovators 88dB, 4Ohm.  The Uniti2 can go down to 4Ohms so I should be good there.  I have a rather large music collection and need the low end but am most interested in sound separation and dynamics - would the impedance difference impact this significantly? 

I'd appreciate your opinions before I (try to) find a dealership that will allow me to home demo these for a couple of days before the hunt starts for a decent 2nd hand pair.

What is your view on the uniti 2 ? Is it something you want to keep or something to bide by with your intended upgraded speakers until something else ?

sure the pmc and Ovators will make an improvement, but to get the best out of them... They are big speakers... They will need a bigger system behind them for sure.

I have the PMC 23s in my study, which is a larger room (approximately 4m x7m, with a lower ceiling, the speakers firing across the width of the room) and I would certainly hesitate to put anything bigger in that room. It might be worth trying the 24s in your room though, as the PMCs are not fussy about room placement. I suppose it also depends on the type of music. Not terribly helpful, I'm afraid.

Hi Toby

Thank you for the reply.  At the moment the Uniti2 definitely goes loud enough - volume is running around 35% into the 8Ohm B&W685's, so it has some go left in it - the power output will also increase if I switch to 4Ohm speakers - Naim Support confirmed this and as far as I remember the S400's were actually paired to a Uniti2 on Naim's older website as a recommendation.

The Uniti2 currently does everything I need (London-houses are small) So won't upgrade before I buy my own place (still a couple of years away most likely!).

Guru Audio speakers love being backed up against the wall and for bookshelf speakers they have plenty of bass, I also live in an Edwardian terrace and also like lots of low end and Guru QM10's ticked all my boxes.

I'd get some s400s then definitely ! Before they stop being available brand new. Keep them until you get a bigger system and they will tell you all about it - and I'm not talking volume levels . If not you can sell them on at a profit in the future as availability / pricing could go right up through the Edwardian Terraced roof.

It is absolutely not on to borrow speakers from a dealer and then to buy second hand elsewhere. It's cynical and underhand.

I absolutely would not use either of the speakers you mention in such a small room. The PMC twenty.21 might work, but whether it's any better than what you have now I'm not sure.

+1 on both points!

Hi

i own 24s and there is no way I would try them in a room that small - they would be over powering both sonically and visually. Gurus would be a good idea, likewise nSats or small ATCs.

I have a living room similar to yours and while I do not have a PMC 24, I think it is too big a speaker for this space. Like HH has said, I am guessing a PMC 21 should sing well and the 23 maybe.

Yes, but the OP uses a sub with his B&W speakers already in a small but high room and is keen to change both, so is obviously a fan of bass or such a sound works in that room I'm guessing.

+ 1.    I'm sure there's some dealers who can let you demo a s/h pair and sell them to you for a good price if you haggle a bit.

A good idea if you intend to buy more Naim in the future from said dealer.

That would be entirely different, and a very good way to go.

I suspect that using small speakers and a sub is the best way to go to get deep bass without boom in a small room, as the bass can be adjusted to suit, whereas a big and bassy speaker will always be just that. My room is twice the size of the OP's and I'd find S400s too big - they might work but they'd look far too large and instrusive - unless that's the look one wants, of course.

Morning all.

Thanks for all the replies - I'll have a look around for some PMC 22's maybe to demo.  

My apologies as well for any confusion regarding a home demo & buying elsewhere - there's absolutely NO CHANCE that I'll try something as silly as that!  I really appreciate the value of having a good relationship with a local dealer and would not in any way jeapordize that!  

The REL 528 does allow me to be more flexible in terms of sound management (compensating for the lack of Room Correction). Maybe I should consider rather keeping it with some smaller PMC 22/3's...

I think you might be surprised at a pair of PMC 20.23 and what they can do.  Put it this way I have a larger (4m x 4.5m ish) room and while I'm not into excessive bass don't feel I need to step up from the PMC 20.23 and they offer (to my ears) better bass than the B&W CDM7NT I had before.

Posted on: 05 April 2016 by hungryhalibut

I had the 23 prior to my current speakers, and they are extremely good. I would certainly try them in comparison with the 21 and the Rel. The 22 is very deep and may not be ideal in a small room. 

Thanks for the clarification about buying from the dealer - you'll see how I thought you meant otherwise!
