mkrawcz, you have a serious speaker problem, and you have my full support. 

Who makes / made those original baffles?

Thanks for the support! Those baffles were made by Captainhemo.

I’m thinking about building a lower end for these consisting of 4 M165 woofers. Basically the  lower end of the NXOticas.

And if my memory serves, we still have a few on the shelf, as well as a tri-angler lower section that houses 4 drivers, I believe matches the mini’s width.

So I’ve been listening to these speakers blended with the double troubles and I’m having a difficult time listening to anything else. These speakers are amazing. Listening to “Hurt” by The Ghost of Johnny Cash, when the center vocal image starts, it is the most realistic sounding thing I’ve experienced from any speaker I’ve ever heard. The scary thing is they have much more potential in the form of a proper base using M165 woofers to take over below 200hz vs letting the subs fill in up that high.

Fellas... posts like this... they cost people money.  And sleep. 

mkrawcz.... COOL!!!!

Here are Danny's measurements. Worked out really well with just a low order filter. Working on getting a prototype wedge stand that will have 4 M165 drivers. It's going to be tough to beat.

Oh man that's looking like a fun speaker. I was thinking that on top of my Rythmik F8 would be pretty amazing in my small room. Not like my Studios are any slouch speaker...  Those Super Mini Deluxe would be like a headphone system for your room.

[HAL]

Yah, did that at LSAF2023 with two single LM10n planars and two 3x12 modular OB servo subs in a nearfield configuration using the dspNexus 2/8 with the AK4499 DAC's.   Sounded pretty good to me.

[mkrawcz]

You can see in the frequency response and the waterfall how ridiculously good the LM10N is.

[goggle1824]

Super cool project mkrawcz! 

~$700 for two LM10N drivers currently from Radian (just to add pricing context for historical relevance) 😇.

I’m curious how these might compare to the OG Super Mini’s and something like the MTM NX-Otica’s.

[Endo2112]

Having heard many BG/Radian 10 drivers, I think it’s important to give my 2 cents, and that is that as these drivers start playing lower, distortion goes up, particularly if only one is used. I would contend that, as Radian says a 500-5k range would provide max output, lowest distortion but ultimately that lower region needs to be augmented with an 8-10 inch driver before hitting the subs. This optimization can clearly be seen in Igor’s ( the gentleman who designed both BG/Radian 10’s) speaker as he uses a Radian3/10 to a 10 inch OB, followed by a 12 inch sealed where each driver is working its correct space. Even if you look at Danny’s charts above you can clearly see the 10 starts to fall off the table ~350, and I would also contend that there is a lot of mid-bass slam between 150-350, and I personally think that although the OB subs can play up too 200, that’s probably not optimal for a 12 inch driver. To go one step further, I completely understand that a lot of folks here like to use passive X-overs, and that adding another driver into the mix can get quite expensive so I completely get why folks like the simplicity of a small, 2 driver solution.

Sorry for the early morning ramble, at the end of the day it’s the sound that matters, and if you like the sound, great!!

Don, we totally hear what you're saying. The old adage "horses for courses" also reigns true in audio where asking one driver to handle all solutions is tough. I will say, looking at the graphs again it could be an awesome pairing to a set of F8 subs as they're both a few db down in that 200-300hz area which should be a smooth (and still punchy) handoff. Plus in my small room these subs benefit from room gain and still increase in output all the way to 16hz.


I need new speakers like I need a hole in the head, but here you guys have me scheming how I could pull off having another set around the house. Baby steps... I don't need new speakers......

[mkrawcz]

Yes, these drop off fast at 200hz and just having 12in OB servo subs doesn’t really cut it. Adding 4 passive M165 woofers is the way to go. I doubt even the 8in servos will be able to match the speed and clarity of the passive woofers. I will say without a doubt these surpass the NX-Oticas midrange and up by a good margin having both of them. It sounds so realistic it’s hard to distinguish the recording from someone actually singing in front of me and that’s just based on having them on top of the Double Troubles. I already have a good idea of what it’s going to be like configured like the NX-Oticas with the 4 woofers and I can’t wait to experience it.

[Endo2112]

I totally agree as I’ve owned both the Otticas & the Extremes, those 165’s truly fill in the gap!! I would say that the most important difference between the two is size and fullness, and further to that the Otticas can be the better speaker depending on the size of your room, they are a very confident, younger brother!

Cheers,

Don

I didn’t know these existed, the design is so unique and cool. Awesome project!

OK, which one of you guys is volunteering to design, construct, and test this speaker with the GR Neo tweeter, Radian 10, and a 10" OB midwoofer with a passive crossover that will eventually hand off the low lows to a pair of double troubles or triples?

Let's work on the name for this speaker -- how about Radi-OBie? Or perhaps the Ten-Ten Turb-O? Or maybe the OB-bligato? For some of you guys, a more suitable name is OBsession 10, followed up by the massive Obsession 15 which has a 15" OB midwoofer.   

[Tyson]

Yep, once you get used to planar midranges it's hard to go back. 

[HAL]

Radian has a LT3.2 planar tweeter that is a possible alternative from the BG NEO3PDR.  They fit the NEO3 waveguide with an adapter that I am testing. 

[Endo2112]

Tyson, unless one prioritizes dynamics as planar’s don’t move air, not saying I don’t like their seductive sound. There’s just a snap that missing in the range that I previously mentioned, the issue is how important is that to you, and your listening experience.
