Has anyone hear used the 8" servo subs danny used to sell.does anyone have some they want to sell. I have the super minis and right now my wedge cabniet uses the 165x woofers 4 per side and side fireing. I have moved into a large house with a much larger space of 27x29 ft and im missing some puch in the 100 to 200 hz range. I want to build the nxtreme cause im sure they will solve the problem in that range but since danny is out of the drivers right now i got to thinking aboit how else i can solve this problem. Im pretty sure that 3 of the 8" servo subs per side would solve that problem. What do you guys think.

[Hobbsmeerkat]

I've heard from several users here that Dual 12s are better than triple-8s. Tho I do appreciate the smaller form factor of the old 8" subs, and I wish Rythmik sold a single 8" sealed sub, instead of dual 8s. But with most recommending the 12" drivers for its better performance, thats what ill probably end up going with.

[Ryan0348]

I have have dual 12s and the sidefiring m165 base. Theres still something missing. Dannys shop pair of super minis use the side firing 8" servo subs up to 200hz i beleive. I have tried running the 12s up higher at my old house and it did help a little. Maybe ill try that in my new room

[Keithh]

I have 3-8's in a wedge and the output in a 14'x21' is barely adequate and I am being kind
with that description. They were in 9x11' room and did much better but the output was still below par.
So I would say forget about trying to use them in a room your size.
Rythmik was little help with them, but when talking to Danny he said the 12's go a whole lot louder
so that makes me believe the 8's just don't have much output.

[Ryan0348]

Ok. Thank you very much. My system goes down into the 10s pretty easy with my dual 12s and rear room rhythmic subs. Its just that 100 to 200hz range where drum whacks and hits are. That range the freq starts to become directional and the sidefiring woofers dont help in a room my size. Looks like i should go ahead and build the nxtreme as soon as dannys gets the woofers in. 8 woffers front mounted will really help in that range dont you think

[mlundy57]

Have you thought about building your stands with the four M165s front firing, like they are in the NX-Otica?

Ok. Thank you very much. My system goes down into the 10s pretty easy with my dual 12s and rear room rhythmic subs. Its just that 100 to 200hz range where drum whacks and hits are.

You said you had dual 12's. Are they Rythmik servo subs? If so, your subs should be set to cover most of this range. 

[Jonathon Janusz]

You might want to try the nx-otica monitors as a direct swap-out for your super minis.  It reads to me like you are describing the main subtle difference Danny has mentioned when folks have discussed comparisons between the super-7 and the nx-otica; the super-7 has a little bit more finesse/detail in that range where the nx-otica trades that for a little bit more body.  As long as you're happy with the SPL you are getting with the super minis in your room, you might not even need to go higher than the nx-otica monitors and your OB subs. 

Also, the monitors make a relatively inexpensive way to dip your toes and and see if the nx-series speakers get you where you want to go, and you could reuse your drivers to build out one of the bigger models if you end up wanting to scale up from there.

Mike;

The reason that the 165's are not front firing in that bass unit is that the length of the Neo 10 is too long and would push the tweeter height to high.

Jonathon;

It really comes down to personal taste, yes he would gain some mid range fullness with the NQ-MTM's, but he would also loose some imaging and focus to the presentation that the Super Mini's have, which is quite special.

[Ryan0348]

Yes don is right. The sidefiring makes the base stand shorter for the correct tweeter height.

You said you had dual 12's. Are they Rythmik servo subs? If so, your subs should be set to cover most of this range. 

the dual 12s are gr research h frames 2 per side. In the rear of the room i have 2 rhythmic lv12s ran in the oppsite phase of the fronts. They pull as the h frames push. I messed with setup more last night using rew to get the phase closer between the h frames and the minis bases. Its a little better. I also raised the h frames low pass point to 125 hz and that helped also. All my subs are connected to a xilica xp3060 active crossover then i use it for the crossover points. I mostly use it just for its 6 linelevel outlets cause my schitt freya would proly short out with 6 amps on its outputs. I guess im proly also trying to compare theses to much with my large fastrac horns with dual 15" drivers which are awsome in the 100 to 200hz range for the hit of a drum or whack. They are nowhere near the detail and soundstage of the super mini.

If your 12” OB servo drivers are 16 ohm, you can add a 3rd driver to each side and take them up to 200Hz. Triple 8s covering from 40Hz up to the Neo 10 would be optimal if they were still available. Since they’re not, the third 12” driver would be my next choice.

Do you have the A370PEQ XLR3 sub amps ? I believe they have the ht input which bypasses the internal c/o.... if you  are using  an active cross over anyway, just   cut out the   M165's totally  and    let the   12's play up    to the  point that   gives you  a flat reponse between them and the  Super Mini's

And yeah ,  the  NX series do have more body than the Super series  , the  Super  series   is more  ana litical/detailed l.. not that  the  NX  doesn't have detail,  they are  just  different.

I have the hx300 amps. I turn the crossover point on the hx300 as high as it will go which is about 200 and then do all the crossover in the xilica. The speakers are 8ft off the front wall and 9 ft apart. I am 9 ft from the speakers. The closest side wall is the left wall and it is 9 ft away from the left speaker. The wall behind me is 10ft away from me. My setup is kinda messy right now till i can strighten out the wires. The amps and dac what not will remain on the floor though to keep out of the imaging

[Ryan0348]

How do i turn the image lol.

[Early B.]

I have moved into a large house with a much larger space of 27x29 ft and im missing some puch in the 100 to 200 hz range.

Prior to responding, I should have focused more closely on this statement in your original post.

Geez, man -- that's an enormous room to pressurize! You need more subs!!!!! Stack 'em high, dude.

I’ve found file size to be the determining factor to orientation. If the file was too big, the picture posted sideways. When I saved a copy of the file as a JPEG at 50% or so (low to medium quality), the picture posrs right side up.

Part of the problem is the amps. The HX-300 does not have anywhere near the adjustibility of the A370 series amps.

Another issue is positioning. Woth OB you want the speakers to be closer to each other than to you. Also, the closer the speakers are to each other, the more midbass coupling you will get. This is a balancing act because the farther apart the speakers are, the larger the soundstage. You are looking for the position where the speakers are closer together than they are to you but as far apart as possible without diminishing the midbass.

Try positioning your main speakers 6ft apart Instead of 9, then start moving them away from each other about 6” at a time until the midbass starts dropping off.

That is a rather large room for the Super Mini's.  Mine are in front of the short wall about 8' apart.  Mike's suggestion of bringing the mains closer together is a good thing to try.

Since you are using a Xilica xp3060 XO to setup the system, have you done the time delay for the mains, so the dual 12" servo subs signal arrives at the same time as the mains?  The subs look to be a good distance behind the mains, so delay adjustment will help with system integration.  Have done that many times to great results.

I use the HX300-12OB amps with my 2x12" H-Frames and digital crossover with my Super Mini's and they sound very good to me.

The HX300-8OB servo amps are the only ones for the 8" OB servo subs.

 

[Ryan0348]

I think the room is just to big for super minis. I think once danny gets the woofers in for the nxtreme ill go that route. The super minis and the bases dont run through the xilica only the subs Front h frames and rear room ported lv12s. The h frames are 1.5ft behind the mains. Shouldnt that be close enough at those low freq. Ill try bringing the minis closer though. Thanks

[HAL]

It is a time delay of 1.3mSec from the servo subs to the Super Mini's due to the distance.  Even at low frequencies, it is a mismatch of the two wavefronts.   

The good thing about this type of setup is that you can find the best spots for the mains and the servo subs in the room. 

I use my DSP XO for both the Super Mini planar drivers and the servo subs, so the time delay offset is easy.
