The full NX-Otica has better upper/mid bass.  But it needs subs you really don’t want to run it without subs.

Yeah makes sense. That is how I think of it as well. I would not think of it as 2/3rds speaker. It is like the old V1, to my thinking...

I definitely would want the ob subs with either version. So the mtm version allows me to have a smaller footprint and I guess give up a little bit of the upper midbass.

Can you explain in what way it is not?

Is a full Nx-otica alone (no subwoofer) better sounding than a Nx-otica MTM + dual ob servo subs?

What is missing on the mtm with dual ob subs combo?

Thanks

I think the point for Danny it’s that it is not a complete speaker if just the MTM section is used. For example, the MTM double trouble combination is basically the same type of speaker as the Super 7 with different midrange drivers. However, the Super 7 has both parts combined in one cabinet so it is full range in one cabinet while the MTM/Double Trouble set up is two separate cabinets that work together and because they’re separate, somebody could build just the MTM section and try to call it a day. That won’t work though. Both parts are required to make one speaker.

For my part, I understand that and would never consider the MTM section as a stand alone option. The one cabinet solution is neater but for me, the two piece solution works better. That is because I have to wrestle the speaker up a flight of stairs that has a 90 degree turn at the bottom of the staircase with the first three steps at various angles and tread depth then another 90 degree turn at the top of the stairs into the music room. Getting the 100 pound sub section up the stairs and into the room is enough of an issue without having to contend with the added height and weight of the MTM section. If the system was set up on the first floor of the house, the single piece version would be easier to deal with. This is why I can see the benefit of both approaches depending on the situation

I think there would be a decent demand for Otica MTMs. Potential buyers would understand they're designed to be paired with OB servo subs. Of course, I'd be interested in MTMs with the new 8" drivers which would likely produce a more gutsy midrange.

I think the main 'issue' with the Otica MTM on top of the subs is visual/aesthetic.  They just don't look like an integrated design.

I'm mostly talking visually speaking. A wedge shape speaker on top of a large, rectangular box isn't exactly a "cohesive" image in terms of design.

There are benefits to having the 4x 6.5" woofers vs a pair of 12" subs, as from 150-50Hz the 4x 6.5" woofers only have to move a tiny amount for the same level of output, plus they're also much lower in mass, so all of that combined offers better speed and clarity in the mid-bass, plus rolling off the bottom end of the Mids improves their clarity as they aren't trying to reproduce anything below ~200Hz
So the large 12" subs only have to play the lowest Octave.

It's not to say you cant still get great sound out of the MTM+dual combo, because you definitely can, but there are trade offs.

But they were also designed for different applications.
The MTM was designed for smaller or more moderately sized rooms, where 4 full towers isn't a realistic option.
It's the same reason we offer both the ~7' tall NX-Tremes and ~5' tall NX-Otica, and not just the NX-Tremes only.)

It's why were working on a version with 3x 8" servo subs built into a single physical tower.

I have the NX-Studio kit and an NX-Otica MTM kit.  I just bought 4 Rythmik F8 subs... 8 x 8" servo subwoofers.  I don't have them yet, but I expect them to play well with everything, and probably fit with the NX-MTM pretty well. I do plan to put the NX-MTM on top of an F8 subwoofer, and I have an idea for how to finish them off to make them look like it was designed together. We'll see.

[Denton J]

Does anyone have an image of the MTM's?  I'm trying to picture what this would look like.

Side question, I don't have much space for the amp box.  I'm probably going to get the sealed servo sub unless I can run a 7-10 ft cord from the preamp to the amp box & back to the sub.

Is 7-10 ft too long of a run?  The other sub will be fine.

I really enjoyed hearing Danny's open baffle subs.

I like the idea of MTMs because I enjoy full effortless mids.

7-10 ft from the preamp to the sub amp is fine. For the OB subs, it's the distance from the sub amp to the speaker that is important. That needs to be close. The recommendation is to only use the wire that comes with the sub amp. you put one end of the connector on the sub cabinet and the other end on the stock wires. That gives about a 2 ft cable from the sub amp. For the sealed servo sub, you connect the stock wires directly to the driver since the amp is built into the cabinet.

Thanks, I know what you guys mean now when you say wedgie.

[Hobbsmeerkat]

The "Wedgie" was an even more narrow model using 4 of the old 3" LGK 1.0 drivers instead of the NQ woofers.

Actually, these are the Wedgies. They use the LGK 1.0 instead of the M165NQ for the midrange drivers with the Neo3 tweeter in a much shallower waveguide. This was Danny's first wedge shaped open baffle speaker.





Here they are on their wedge shaped base with triple 8" servo subs





The Wedgies actually image better than the 'Otica MTM due to the narrower baffle. However, the larger 'Otica MTM has a more robust and full bodied sound, especially in the midrange.  Also, two 12" servo sub drivers outperform three 8" in bass response. That said, for a small untreated room, the Wedgies are killer. I had them in an untreated room that was 11'x10'x8'. While most people I've been around who have heard both, prefer the presentation of the 'Otica MTM over the Wedgie, some have preferred the laser like imaging of the Wedgies and the Wedgies will work in rooms that are too small for the 'Otica MTMs.

As Danny and others often say, there is no best speaker. It comes down to application and preference. This is true for any speaker design.

If high passing the NX-MTM via amp input, what is the ideal target frequency for the high pass filter?  Assuming blending with Rythmik F8 8" servo subs.

This thing of the 8" tower ottica as being going on for a while with no great updates. I've been on the fence on upgrading my speakers for a while and sometime I come back to this forum to check for updates on that but these seems still to be just in the air... perhaps in the meanwhile it would have been nice to have the MTM on offer.

Another thing that is not clear to me after reading many threads here is if the nx-ottica without subs are a viable speaker. Things like: how low they would reach in room and what's the -db figure for the 50hz stated on the site (would be nice indeed to see in room measurments). So one could build a plan to get to the full system with subs one piece after the other, can one start with only the speakers? Would a single double trouble put horizontally work with the ottica (the horizontal orientation should diminish the effect of cancellation a bunch)?

A new all in one 8" would really make the entry point a no brainer.

On their own, the Otica-MTM section is good to between 150-200Hz, so it must be crossed to a pair of dedicated subs that can play up to meet them. Its typically been done with dual 12" woofers as both the subs and as stands.

The main struggle with the full tower with 8" subs has been getting the cabinets cut due to the limitations of our CNC machine and the programing time it will take to design what we have planned, plus we have several other projects we're working on that are taking up machine time. The custom amps are currently in production thankfully, so we'll be able to offer the 8" subs as dual or triple woofer stands once those come in.

A single-Double would work okay for the standard Otica in a smaller room, but will not work for the MTM version, as the subs need to be much closer to the speakers for proper integration.

The only in-room measurements we have have a high-pass filter in the system, so it's going to be lower than would really be accurate for most people.
being open-baffle, extension will depend on the room and their placement. Smaller rooms may get -3dB at 45 while larger room may be -3dB at 55-60Hz.
50Hz is the -3db figure.

This is a REW measurement of my MTM in my room at the seating position. My room is 16x24 and is pretty well treated. Speaker is 5' from the side wall and 7' from the front wall. This is 1/3 octave-no crossover on the lower end

[Hafgrim]

Has gr ever experimented with ripole bass? They are much more compact than h frames and theoreticaly provide more output. The 12 inch servo woofers should be able fit in the oticas near perfectly.

Great news!!!  Got any idea what that might look like?  Sealed or OB, both?
