My apologies, I am refering to analog XLR (AES48), meaning one can use any traditional preamp with analog, balanced XLR outputs.

Hello, yes the main tower speakers still contain the built-in Analog x-overs. I guess I haven't found the courage to physically remove/replace them yet for an exclusive all Active x-over configuration. I suspect my courage would increase greatly if by some chance Magico stops selling parts for broken components (God forbid)
.In my case I chose the compromise of using Digital x-overs baked into the signal using Convolution files which are created using Audiolense software. The Convolution files are then used against the Digital source music files coming from my NAS by the Roon music server and processed there, all in the Digital realm. Lastly, my 5 Digital channels are then forwarded to my 8ch DAC by way of Ethernet where it is converted to Analog and then sent out to each Amp in the chain.
There is only 1 DA stage in the whole path. Once the signal goes Analog it remains there for the rest of its journey despite all the above activity having occurred before I got to hear the first note.
Breakdown is as follows:
Channel 0 = Left Main speaker see's only 60hz on UP, is Phase/Time Aligned and Vol matched to all other speakers
Channel 1 = Right Main speaker see's only 60hz on UP, is Phase/Time Aligned and Vol matched to all other speakers
Channel 2,3 & 4 are Mono Sub Channels and are Phase/Time Aligned and Vol matched to all other speakers.
The signal from both Channels 0 & 1 between 10-60hz are sent out to Ch 2,3 & 4 equally.
The output level adjustment of all channels is simultaneously done with DSP Vol control within the Roon server and the Roon App on my phone is my primary remote control.
A large studio (Velvet recording) close to Oslo in Norway went full Sigberg Audio this spring. We installed Mantas and dual 10D subwoofers in their control room, and SBS.1 with dual Inkognito subwoofers in their mixing/mastering room. We also did an additional SBS.1 + dual Inkognitos in the home studio of one of the owners. In connection with this we did an interview of the master engineer.
Here are a couple of short clips from that, talking about the Mantas:

I am happy to share that we've received a product of the year award from the Norwegian magazine Stereopluss for our Manta speaker system!
INCREDIBLY IMPRESSIVE!
There is a lot that can be said about tonal balance, tightness in the midbass and the openness in the midrange and treble, but what I am really left with after the test is the almost shockingly precise and three-dimensional soundscape. It’s like sitting in a studio with excellent acoustics, listening to a couple of studio monitors or even better, being present where the sound originates. With an ensemble, band or orchestra at an appropriate distance from you.

We do of course recommend using our own subwoofers, as then you are guaranteed the proper bass quality and response. Also the crossover is preset out of the box. You can however of course also use competent subs from other brands like JL Audio as well.
As you already have a setup with an active crossover (the MiniDSP) in place, you have a good starting point. The Mantas are high passed by default, so they don't necessarily need to be connected via the MiniDSP at all, unless you want to use that to EQ the speakers. They also have built-in EQ, so it can be done directly in the speakers as an alternative.
Just leave your subs connected to the MiniDSP as they are now, and configure the crossover to 100hz 24db/octave. If you have already used REW to tune the subs, that can probably also just be left as is, depending on what your current crossover is.
Is the Mantas high passed at 100 hz? I currently have subs and speakers at 167hz suggested by monitor manufacturer. It seems high but makes a huge difference to the sound. I’ve used 80hz for years but can never go back.
The Mantas were designed from the ground up to be mated with our subwoofers, and were designed to blend well with the subwoofers running a 100hz 24db/octave crossover. The Mantas roll off naturally with an anechoic -3dB point at around 90hz. In-room it will be a bit lower. This means there is some overlap between speakers and sub by design.
If you control the crossover point externally for both speakers and subwoofers (with for instance the MiniDSP), you could cross them higher as well. But with the 12" midbass driver they have plenty of capacity to be crossed at 100hz.
Which speakers/monitors do you have currently?
Manta anechoic response:
Unity Audio Boulder MkI’s from the Uk. I’ve had active speakers for years with active subs.
Are you in the UK yourself by any chance? If that is the case, the Mantas can be auditioned in London.
Those look good. The difference from that and to the Mantas (and our SBS.1 monitors as well) is the fact that they have no intention of playing bass at all, so they use different drivers. The woofers are high power midbass drivers, not bassdrivers. So they have a different suspension, lighter cones and higher sensitivity. They can simply play louder with less compression / distortion than anything of comparable size.
Hi NZ market very small. Would be good to read more reviews of Mantas. Keith at Purite UK puts them slightly ahead of 8c but down plays it somewhat. I prefer the active sub option which you have designed for. If I get to UK next year I will have a listen. But I bought my UK monitors unheard from UK. I find the ribbon tweeters on the bright side. They are not “Cardioid” either.
Keith retails both the 8C and the Sigberg Audio speakers, so it would make sense for him to try to be quite neutral. My understanding is that the Mantas are currently his main and daily speakers.
The Mantas are not bright, but still have an open and detailed sound.
You also have plenty of opportunity to adjust the overall tonality to your taste and/or room:
* The top end can be changed between 0dB (reference), +2dB or -2dB at the press of a button
* Since it's designed for sub you of course have the option of adjusting the gain of the sub as well, which will change the perception of the overall tonal balance.
* With the included software you can access advanced EQ including tilt functions, that will allow you to adjust the tonality further.
With regards to reviews: There will likely be more reviews down the road, but we simply don't have any to send out at the moment - will reserve a pair for reviews when we get more back in stock in a couple of months. In the mean time, you may find the review of our SBS.1 speakers from Jay's Iyagi interesting. The SBS.1 is founded on the same basic concept with the ground-up-designed-for-sub, and uses the same coaxial driver.
Jay comments on both the concept of it being a speaker system consisting of speakers + sub, and on the overall tonality and sound quality of the speakers. There are many similarities between them, except the Manta takes everything a few steps further.
Finally got around to writing an article about designing and developing the Manta. Gives some interesting insight in why these speakers were created, design choices along the way, and how they work.
The Manta will now soon be available in satin white as well, get in touch if you're interested in this color!
The Manta speaker system together with 10D subwoofers have now been reviewed at hifi.nl!
"These Manta’s including the 10D subwoofers from Sigberg Audio are impressive performers. Whether I play classical, rock, metal, dance or music of the electronica genre, this set of loudspeakers offer a most immersive sound experience. Thanks to the precision and nimbleness with which this active system plays my albums, you are treated with a maximum experience track after track. Thanks to the punch, slam and bass extension, live recordings feature an unmistakable live vibe."

"I couldn't be happier with Sigberg Audio’s Manta loudspeakers and 10D subwoofers offering a full-range experience. These loudspeakers are in financial reach of a larger group of music lovers and do outperform most similar priced conventional solutions. My experience with these Mantas can be best described as unforced, neutral and most precise to the ears. The sound spectrum is nicely balanced-out and voices have the correct weight to portray the artist in the room with realism."
