From 31.5 Hz and up, the seven 215RT's can play at 150+ dB!

We're going to have some fun at Axpona this year.

I briefly looked at the NanoAVR DL manual and it doesn't look like it can combine channels, do bass management or set HPF/LPF like the regular version can. Might have to have a regular version sit in front of the DL version for it to work.

Sorry I am unfamiliar with your setup but I think some of this info from the DDRC-88A thread might be helpful. Basically you do not want any changes to the original signal before any decoder. That's why most use the DDRC-88 model.
**miniDSP DDRC-88A Official Thread**8-channel AI/AO Dirac Live in a box

I currently use 2 DDRC-88A's in my system and absolutely love the sound and control it gives me. I do not use the BM plug in add on but I believe it might be able to help add a high pass filter to roll off any ultra low frequencies. I'm pretty sure you can even route the LFE to any channels you want (for those who might be running say 7 215RT's . I'm sure those questions can be answered in that thread. FWIW I use Dirac on my 212HTR fronts, T8 surrounds,and slant8 atmos speakers. For the 4 S2 subs I route the combined sub channel out from the 88A into a minidsp 10X10 for time alignment.

Did a quick REW room sim however I couldn't add a center channel and couldn't make the room large enough. Also, we're not planning on having the speakers all way out to the walls. We'll see how everything measures and sounds once we get in there.

Wow, that will be freaking epic.

I am so pi$$ed that I won't be there to hear that setup.

JRiver Media Center will be used for all bass routing, high pass filters, and EQ. What is nice about a room this size is that the 1st-4th axial length and width modes are all below 40 Hz.

With Blu-ray concerts and movies, the non-LFE bass can be in the L/R channels, just Center, LCR, or any combination of LCR and surrounds. For example, The Art of Flight had some bass that just comes from the side surrounds. There are basically two ways to route the bass:
1. Reroute the LFE to all 7 channels. Each speaker plays fullrange whatever bass was originally routed to that speaker plus the LFE.
2. Combine bass below ~40 Hz (or whatever frequency) from all speakers with the LFE. Then route that to all 215RT's. All speakers play all bass below 40 Hz plus the LFE. This more like traditional bass management, but using all 7 215RT's as the "subwoofers."

I have used every version of audyssey including the pro kit for 3 years and Dirac Live with 88A and for last 4 months the Arcam AVR55O. In my opinion Dirac offers a far superior room correction software. Especially with tegards to voice clarity from center channel and lower frequencies. Nano does require pcm so source must decode and send pcm. I am not aware of any source that decodes atmos or dtsx so best you could get is 7.1 pcm. Also, if your source cant do BM, you will need to rely on your avr or pre/pro (so BM after DL filters) which in my opinion is not the best way to handle BM. You can get good results, but it requires more advance setup prior to running DL.

That's a fun packed day right there... wowzers. If I direct flew I would have to leave an hour before that, so I may still just do the night there.

What does it do then LOL!!!

I think I remember this from when they first came out a while back. It seems pretty dumb but it's not exactly the same but adding Dirac live. I suppose running two channel for the near future I could just get Dirac on my Mac.

It looks like it will apply Dirac to all 7.1 channels but all of the bass management is done in your receiver. I am not positive, but that is what I gathered by reading the manual. It will probably be wise to post a question in their forums to be sure.

If you have the 88a with the BM upgrade, bass management is done via the 88a...not the receiver.

Flying out of little Eugene airport is spendy. PDX is 2hrs north but still they want over $300 one way. Better way to search?

I do remember the 88a getting that update.

JP is thinking of getting the NanoAVR DL which i am not sure had th BM update.

Gotcha...wasn't sure which DL machine was being referenced...thought it was the 88a. Sorry.

Regardless what amp setup I go with it will be on a 15 amp circuit so I won't use the max potential. Not sure I ever would either. It sounds like utter blasphemy around here but I have never ran any of my measly systems off more than a single 15amp circuit. Now dual Submersives I had with each having a SP-2400 plate amp, 4520 running high efficient speakers, TV, Oppo, etc vs the monster DIY 21's, JBL 4722 stereo pair running off 4520, Oppo, TV, etc is the most power I have ever tried to run. One day I will need 20 amp dedicated lines and in multiples though

Ah yes, it's all coming back to me now...... I read a bit upon release of the Nano's as they intrigued me. I remember the whole "Bass management in the wrong place," and some despising them for that. If Jeff endorses it and others use it successfully and it reduces one extra DA/AD conversion then...? I will have to read more...

I do see on Dirac's site they offer 2-channel or 8-channel for PC or Mac. But same argumentative positions of bass management in wrong place right? And unless running all from the HTPC movies would not get Dirac

I think I will just keep Both Crest amps and Crown amps until I can sample them both. I mean for years people have used post processor DSP with an additional DA/AD conversion and it's never been brought up until the Nano release it seems.

I think ideally if the NanoAVR-DL can route LFE to mains along with the Dirac benefits combined with the Crown DSi amps setting the HP filter could be optimal.

But then there is the DL update for the cheaper NanoAVR-HD. So does it maintain all of it's benefits but add Dirac? Yea I'll go read

Pc version if you use jriver which will do bm before. If you rip your movies and music you only have to worry about cable/sat tv and 4k movies. Arcam avr 390 could work for you as a pre/pro and you avoid the extra AD-DA, you get DL on all sources and if you ever get atmos speakers you can have them calibrated as well up to 7.2.4 setup can be corrected.

I received a message from MiniDsp:

"Unfortunately the DL doesn’t run that bass management configuration you’re seeing on the HD and 88A/BM. :-(
Your option for the time being is using a DDRC-88A + BM (bass manangement + Dirac Live) or using a nanoAVR HD + DL in series."

The Nano-HD will give the highpass filter you need and allow you to run lfe to all three front speakers.

The NanoAVR will let you do bass management if you want and HPF/LPF, PEQ etc but once you add the Dirac Live download you lose these.

Each crest 4000 is on its own 20A circuit which were installed during my salt water tank days. 2 of the S2's are on their own 20A circuit but the other 2 share a 15A circuit. I got a great deal on the crest amps locally at Northern Light and Sound. Much cheaper than MSRP.

In my living room I have 4 Triax's all on a 15A circuit. I have gone up to reference with them and didn't trip the breaker. My 4520 is on the same circuit as well as the TV and lights.

Speaking of @rhed , where has he been? I haven't seen a post from him in a long time.

Well, you know it was my dislike of the sound I was getting from my Arcam AVR550 and asking questions that eventually led to markus767 giving me help with determining which REW measurements to take and interpreting the measurements that led to all the noise and eventually Arcam providing a fw update that is a workaround in my opinion. The workaround is that it now runs the calibration Measurements with BM in place which vastly improves upon their completely broken process before, but it still has issues that I doubt will ever get resolved and it rendered the stereo mode useless. Currently, my setup sounds very good and measures well so I am spending time just listening and not measuring, but will be back at it soon. My plan is to wait and see what new equipment comes out with the new version of Dirac Live, but if I had to do something today and I was running 215's full range I would go first with the Arcam and second 88ABM. Personally, I think there are too many limitations with the Nano's to be cost effective solution and requires at least 2 extra pieces of equipment.

Your option for the time being is using a DDRC-88A + BM (bass manangement + Dirac Live) or using a nanoAVR HD + DL in series."

The Nano-HD will give the highpass filter you need and allow you to run lfe to all three front speakers.
I will need one of these regardless to route LFE to the 215's. But the price is very nice. No Atmos for years...So if I want Dirac it's either 88A which adds another AD/DA conversion so definitely would want a non DSP AMP, a HTPC which require prob more cost than I can do right now, or chain a Nano-DL. If I can find a buyer for my trio of DSi amps I could finance a Nano team

Each crest 4000 is on its own 20A circuit which were installed during my salt water tank days. 2 of the S2's are on their own 20A circuit but the other 2 share a 15A circuit. I got a great deal on the crest amps locally at Northern Light and Sound. Much cheaper than MSRP.

In my living room I have 4 Triax's all on a 15A circuit. I have gone up to reference with them and didn't trip the breaker. My 4520 is on the same circuit as well as the TV and lights.

Speaking of @rhed , where has he been? I haven't seen a post from him in a long time.
Triax have SP amps? Super efficient! My two Submersives when I had them I tried to abuse on a single 15 amp circuit but never could pop the breaker!

Yes, they have the 4000w SP amps.

I'm thinking through my gear setup, amplification, and potential DSP for the 215RT's.

Option 1: Originally I was going to simply use my trio of Crown DSi1000 Class D amplifiers that would give me 1400 watts @4ohm s. I would think 1400 watts would be more than I would ever use on these mains, especially with three and room gain adding headroom. But I do like a rising house curve Then Harman's DSP program I would use after an XT32 calibration via Denon 4520 for the HP filter and PEQ. I had read people disliking Audyssey XT32 but I personally have always felt it has done a pretty decent job. I had considered that optimal until recently, see next option.

Option 2: Sell the DSi amps, buy a NanoAVR-DL and use my Crest Pro Lite 7.5 Class D Amplifiers (2-channel) to power the 215RT's. Too much power? I won't ever get the volume that high...They advertise at 7580 watts and I am pretty sure they have bench tested at 4480 watts or 2240 per channel but @beastaudio can confirm. I have the non DSP versions so no additional D to A conversion and the NanoAVR as we know is HDMI in the digital chain prior to the processor. I have two of these Crest amps and could modify my classified add of my DIY 21" subs to passive units only and keep the one amp I was selling in the subwoofer package. In the future I would still have one channel of the four available for subwoofer use. That doesn't cause anything funky does it using one channel for a main and one for a pair of SI18HT's?


Option 3: Keep the Crown DSi 1000's and still get the NanoAVR-DL and use it for DSP. Ignore the extra D to A conversion as it won't affect anything at all. Sell my one Crest amp with the subs then keep the other for the eventual quad pair of SI18HT smoothing/near-field subs.
IMHO, you should try the 215RT's run full range using XT32 setup. I'd add the 15Hz HP if your amp allows this. Listen to them with Audyssey EQ on, then use the L&R Bypass mode and finally no Audyssey. See how they sound best to you and of course measure the FR.

That will give you a baseline from which to tweak.

Just my $.02

Thanks Rob I like ease!

I have to admit in my researching thus far I am shocked at how many people did not know how to tailor the bass post XT32 calibration. I used to use an Open DRC-AN teamed up with XT32 with dual Submersives. I would take my raw response, apply PEQ to pull down peaks, set my low shelf house curve then simply click bypass. Run the XT32 calibration after the manual PEQ then get a much nicer Frequency response. Then simply 'unbypass' my low shelf and good to go! This could be done via the Crown amps DSP capabilities via Harman's Audio Architect software program. And set the HPF. For me this would be the by far easiest as I have the gear (Crown amps) already. And it's as easy as in plug in gear, run XT32, apply HPF, apply personal low end house curve to taste, done. Or if it has a bypass feature like the Open DRC use in tandem.

I don't know at this point where I will end up. I have more reading to do before making long term final decision. I want to find the best way out there and have come across the Motu unit's being discussed. Need to read moar!

But at this point my mind is swaying toward using Crest Pro Lite amps to power the 215RT's. I have a couple Pro Lite 7.5's I bought for subwoofer use. I would still keep one for subwoofer use and the other for LEFT and RIGHT 215RT's. This would give 2240 watts per L&R 215 then snag a Pro Lite 3.0 ($449) which bridged would give the center 3125 watts. I know a lot of power and 20 amps dedicated circuits needed. I most likely will never hit half of those numbers but we like to have a 900hp available right? Then possibly implement a Motu 16A in for LFE routing, HPF, manual PEQ of each channel and have EVERYTHING simplified to one box. Would mean no Dirac but let's admit even in the realm of non audiophilia we have been fortunate to buy our ways into with our gear we can still get "swayed" by snake oil arguments disguised. I'm not saying Dirac is not good and it is in fact easier as in plug and play and the saved curves are nice. But it cannot manipulate physics and really in an honest sense does no magic. The same benefits of achieving a good frequency response and time domain graphs (waterfall,Spec) can be organically effected by organic EQ aka absorption/diffusion properly placed.

A point to remember is I am doing a simple 2-channel setup next to my TV for now and for a time period after we move. We are having 2nd meeting with realtor a week from Friday and we have been looking at homes in the new location with either a bonus room or a garage I can convert/build my own room. I am leaning towards a garage as I would prefer 9ft ceilings and could build Atmos speakers flush/into ceiling above...

Will try the bypass L&R as my 4520 allows this. But in my horrible for bass response unsymmetrical living room XT32 was a must. I suppose the cheap cost of a Nano-HD would be a drop in the bucket considering I could keep XT32, route LFE and add a house curve. Could be a cheap and somewhat temporary solution

Audyssey for me was better than no Audyssey. However Dirac Live compared to Audyssey is night and day difference. Almost nobody goes back to Audyssey after hearing Dirac in their room. Add to that the ability to have any kind of house curve you can imagine and well no contest.

I've always wanted to try Dirac but it will have to be in my next processor. I've had the chance to try out ARC.... wasn't very impressed vs audyssey. The AVM60 was good but I felt the 7702mkii was equal. One thing I have to say is audyssey has the sub bass down pat over ARC, just much better.

I have no interest in minidsp's solution, so it would have to be into my next processor.

Blasting brown notes for 10 years and counting!

I assume you mean bass with a house curve added after yes? Or sub trim raised...

I truly felt my old XT32/Open DRC EQ system was pretty dang good! Set 4-6db house curve around 50hz give or take then bypass so Audussey doesn't pull it down, Pull down peaks of Raw sub response, feed Audyssey the manually PEQ'd response for a finer tuning the un-bypass for a smooth rising bass response.

You still use Open DRC's Nate? Don't wanna try Dirac because Mini dsp unit okay for subs but not speakers?

My original setup for the 215's (pre Atmos) was an Integra SSP with the LFE channel(s) routed to the LCR's via a Rane RPM88. The Rane also provided HP filters and PEQ capability in addition to or instead of Audyssey XT32. I was using an Lab Gruppen FP10000Q for LCR power. Like N8DOGG, I'd like to try Dirac but I'm not going there until it is a stabilized function of the AVR or SSP and supports Atmos/DTS-X). I'm guessing that's a couple of years out.
