SNAXO BMR and SNAXO BMR upgrade kits

Hi the S600's require the SNAXO BMR, which has a crossover suitable for the BMR in the Ovators. The Crossover upgrade kits before convert  the crossover frequencies of the Snaxo242/362 to make them suitable for use with the Ovators. They will not have the floating chassis of the Snaxo BMR however.

Thanks. Probably better to go with the BMR Snaxo then I guess. I know you can use 2 or 3 amps to drive them as effectively they are 2.5 way speakers but still not sure if it's a 2 or 3 way Snaxo, or am I missing the point?

Yes, you can use either 2 or 3 amps to drive the Ovators. The Snaxo BMR has 3 outputs 2 of which are identical for the bass drivers. You can choose to use two outputs one for the BMR the other for Mid/Bass, but will need to use the naim speaker cable adaptor to convert the single Mid/Bass cable to both Mid/Bass inputs of the speaker.

The BMR Snaxo is the way to go as it is an upgrade on the older models, and much heavier.

Did a bit of digging. Still confused as to why this information isn't on the Naim website, but I now realise that the converter is not for the Snaxo 242 or 363 but for the Ovator speaker itself and replaces the passive crossover if you need to convert from passive to active. I thought it was odd that the 242 converter was more expensive but that's because it includes the y-link to allow you to use one amp for both bass drivers. That  makes going active on the Ovator a fair bit pricier than on SBLs or SL2s.

well,those are regular two-ways.

This is what you need:

This is a pic of my S600 one - note the suspended sub-chassis - if makes a difference!

I now have the S800 version, which I have never opened, but it probably looks the same.

Now I'm confused, But as far as the Orator 800's goes:

Floaty Chasis only applicable for S 800's Correct?  Yes! 

But what about the next line!

I have noticed a gentleman on the Forum is using 3 500's to power his 800's! 

I thought!!!!

1 amp to power the Tweeter

1 amp to power the Mid Bass/A 2- way configuration 

or 

1 amp to power Tweeter

1 amp to power Mid

1 amp to power Both Basses/A 2.5- way configuration

Hence two or three amps could be used with the BMR for S 800's only! 

is my thinking correct???????  

Both Ovator S600 and S800 Active snaxo crossovers have floating sub-chassis inside, but have different crossover components required for the different speakers.

Both S600 and S800 are two-way designs. This means there is one low-pass filter and one high pass filter required to split the frequency bands to the groups of speaker drivers.

The two bass drive units are identical and can either be driven from a single Power Amp or each separately driven by a power amp to get better power-handling and linearity, if desired.

The single BMR drive unit requires one Power amp.

So you can use two Power Amps or three Power amps to drive the speakers, but they are still a 2-way design.

This applies to both S600 and S800 designs.

It's a shame that the Ovator design wasn't similar to earlier Naim speakers in respect of converting to active. It's expensive enough adding the extra active crossover/power supply/power amps and cables without having to pay to replace the speaker terminals with the BMR conversion kit after removing the passive crossover. Not a problem if you are buying active from new I know but another consideration on the second hand market where active speakers will probably be much rarer.

Mark you sound like an Active Fan Also, Speakers are a funny thing, if you like the way they sound, you like the way they sound! But this is exactly why Many were hoping that the Focal/Naim Merger would lead to More Active Home Speakers. But when Graham just recently visited the Naim Factory, there response was, Well you know the Ovators are up to the Task! 

So for us Active Fans it's Ovators 8 & 6 hundreds, and  Classics like the SBL's , DBL's, NBL's, IBL's, and the Isobariks!  

But remember, if one chooses the Classics, there's no Floaty Snaxo.  OH, Well!!!! 

But Thanks Mark, your inquiring confirmed that I didn't really understand the BMR Snaxo's, but I think I got it now!

The Ovators are indeed a two way Speaker, which can be operated Passively, or Active! 

Two Amps is all that is required! One Amp for the Bass Drivers, and the other Amp for the Two way Systems.

The BMR XO has Three outputs on it rear, where two our identical, which allows the 2nd and 3rd Amp to power the Bass Drivers Independantly!

I would Imagine, with the latter option, the Bass is surely kicking!  One Amp dedicated for each Woofer!  Wow!!!            

A lot different from My Briks, Which is a Three Way Speaker System!  

Simple!!

1 Amp for the Tweeters

1 Amp for the Mids

1 Amp for the Woofers

Well that's modern Technology for you!!!!

Indeed, very much an active fan. I've been striving to get back to where I was about 20 years ago when I last had active. At that time it was Isobarik PMS. That was the early version before the passive crossover was moved outside the speaker and into the stand. On that version using the Naxo 3-6 the split was bit different;

250 one to tweeter left/right

250 two to mid and bass left

250 three to mid and bass right

I loved that system, fronted by LP12/Ekos/Troika through Nac32.5.

In many ways they system I have now is so much better...BUT...my god, the old system was musical at an emotional level! And when you cranked up the volume it was visceral, almost scary sometimes but always thrilling. Guess I don't have to tell you that though

Also the S400, I think that can now be run active also. Although details on that seem even more scarce than the Snaxo BMR. A couple of dealers have suggested that they thought so anyway.

That would be good news indeed.

Google Snaxo BMR, there's a dealer website that clearly states that the S400 can be converted to active using the 362 BMR under it's listing for both the Snaxo and the S400. Absolutely no mention of that on the Nam website though so I can't verify the dealer site accuracy. I did have another dealer say they thought it could be done though.

DB - how did you get the suspended chassis - I am very jealous?  My 362 is at Salisbury now, and I had no idea this was an option.  Would love to hear more...
