Agreed. When I got mine home that first night I just used my AVR and listened for a few hours. I loved them from the get go even though I knew I would be boosting the bass when I got them hooked up to my inuke dsp.

I see people saying the 215's are more laid back than the 212's. I have not found that to be the case but we might be talking about 2 different things. I feel like the 215's have more energy way up high, like above 8- 10khz - the frequencies that I like that give a more sparkly/sizzle sound.

The 215's do measure higher above 10hz but I'm not sure I trust the accuracy of the omnimic that high up.

The 215's also just seem to have more "presence" to them. Since I got them I turn up my 212 center channel a couple of db's which subjectively seems to match the 212 to the 215's in volume. When I had all 212's up front keeping the center the exact same volume as the l and r speakers seemed perfect.

I can sure understand a pair of 215RTs for a 2 channel music setup. Should be incredible!
For myself, in a combo movie music all purpose room, my 228HTs and Submersives work nice and were super easy to implement with no special amps or other hardware needed. Would think the 215RMs with equal quality subs would be ideal in my case and no special effort to get up and running.

Wish there was posts from others here with a front of RMs and subs to get some comments. Would like to know the benefits and possible negatives of the RMs as they are a sealed design as I understand it. Would like some comparisons to the 212HTs and 228HTs in use. Very few here using the RMs it seems other than as a center channel with 215RTs.
Thanks.

My daughter got confirmed today, so not much time to fool around. Went out after for a big Italian dinner and I feel like a blob. I am going to head out there in a bit and light it up.

I only fooled around a little bit last night, but they do seem laid back to me compared to the 212's, but it was late and I really did not push them. My AVR was also shutting down for a little bit till I figured that out. They defiantly are not bright, the 212's seem much brighter to me. I will add something is holding back my highs and I don't know what it is. Do you bypass the PEQ Carp? right now mine seem like they have bag over them. I need to unleash the fury LOL

Why is your AVR shutting down if you are running them off an iNuke?

No peq I only use the dynamic eq. Hmmm something is weird. Hook them up to just your avr and see how they sound. Like Jonathan said I don't understand why the avr would shut down when you aren't even using the amps in the avr...

I have no idea? I must have something set wrong. I think I had the gain to low and the AVR was running to hard? It did once tonight. When the AVR does shut off, I notice the fan on the inuke is racing? I have only had the Denon shut down once and that was because I put a hurting on it.

I did figure out the hiss, it was the PEQ. I shut it off (bypass) and silence. I reset it and made some adjustments, but it seems the more you gain on the PEQ the more hiss you get. I have a tiny bit right now, but nothing like I did earlier. With that I have to say I used the graphic EQ in the 4520 along with the PEQ in the inuke and these speakers are downright fabulous. I am in love. Going to need some more bass, but I have that covered I'm happy. I have yet to watch a full movie, so that is going to be the other test.

Well I spent a good portion of the night listening to music and the 215's just do music so well. The one thing I noticed is they need to be played loud! They don't seem to shine like the 212's at lower volumes and rightly so. Overall I am very happy with the way they do music, but not so happy with movies. I don't have my surrounds up yet as I have not had time to get them mounted, but just listening to the front 3, something does not seem right and again I could have something not set right, it could be a million things. My AVR is acting up also, I was having problems last night with it not accepting commands. I had to unplug it twice. I will explain the best I can. It seems for me to get the dialog of the movie to sound good I have to crank it up, but when any LFE hits, it is just so loud and overpowering, it sometimes is to much, actually it is to much. It also does not have that sparkle, like in WOW, the glass does not seem crisp and life like, but more dull. Going to work on getting some stuff done out there today, surrounds are #1 and panels are right behind and then some more tuning later in the day. I am really hoping I can get this worked out. Again music is incredible with the 215's, I did some Pink Floyd later in the night and I was smiling, that good.

You really should bring over someone who has a lot of experience with DSP's / Receivers/ Amps to help you. Everything you feel is wrong with the 215RT's is likely setup issues.

Please reset your micro processor in your receiver a couple times then try again as well. Read the manual on how to do this.
(this will delete any Audyssey calibration you have done as well.)

Wish I was closer to you and I would come over to help, but any others in or near Florida willing to help?

I was going to do a hard reset and go back to factory new and just start all over again. I will be the first to admit that I am really new at the dsp thing. I have to say I feel like I have it set well with music, it is just the movies that seem flat. The word around the campfire is that these are not movie speakers, but I am hoping for better than this. I am going to run just the AVR today at some point and see how that goes. I don't live in FL, I was just fooling around with my location. That is where I want to be, however you are still very far from em, but thanks for offer anyway.

Sounds like your receiver may be source of your troubles with movies. Seems odd that it keeps shutting down and/or needs to be reset.

Seems like it is always something. I rewired my system last week to clean up the massive tangle of wires. Instead of helping I now have a hum that I did not have when the cables were a mess. Opposite of what one would expect.

While I am not a 215 owner (I have the 212s), I doubt very many people would express it this way. A good speaker is a good speaker and should be able to excel at both movies and music. I think the reason we see the 215s being mentioned with music is because you can run them for 2 channel music at full range and don't need a sub..whereas a speaker like the 212s needs subs to run full range 2 channel music.

Actually can we get some feedback from 212HT user who upgraded to 215RT's.

When you "upgraded" do you feel it is:

Not as good as the 212HT for Movies

About the Same as the 212HT for Movies

Better then the 212HT for Movies?

Just to add, Jeff was the first person to tell me that the 212's were more dynamic and would be better for movies. But yeah, user feedback is defiantly the real answer here. There is also a few other people that have the 215's and I have not seen or heard from them in awhile. Would like to hear from them also.

Umm, that would be a BIG negatore. If anything, the opposite is true due to the larger image the 215's throw. I feel the sound is a little better across all of my seats with the 215's. Actually, the 212's with well integrated subs are the equal of any system I have heard for movies at the main LP. For music, the 215's run full range (in the right room) from the LP are something special. If the dynamics are less with the 215RT's, it has gone unnoticed by me .... I think Jeff might be trying to discourage some from going with 215's due to setup complications. They are not plug and play speakers and it takes s little more work and setup to get them optimized.

There are many factors at play here and getting the speakers setup properly is job 1. There should be no hiss or hum coming from the speakers. Have you (Reef) tried the 212's with the current setup to see if you have the same or more hiss/hum?

Update, I do find that I run the 215RT's 2 (+/-) db louder than the 212's for action movies. That may be due to a slightly softer top end ...

I feel the 215's are better than the 212's in every single way. My experience is very different from Reef's. I do agree they are a bit more laid back than the 212's but IMO that makes them that much better. I found the 212's bright at high volume but the 215's are much easier on the ears at high volume.
As for movies, again, I like the 215's better than the 212's as they seem to have more presence, like the wall of sund they emit seems epic at times .

It sure seems like Reef is having other issues in the chain. The good with music and not with movies thing never sits well with me, like Forlich says, a good speaker is a good speakers, if it does one thing well, it will do everything well.... until it's limits of course.

Complicated? Only for the uninitiated.

I first did bass management on the rear surrounds with 24 dB/octave slopes (I think) on the high and low pass. This mixes the redirected bass with the LFE and maintains proper levels.



Then I added the LFE to the Left, Center, and Right speakers. When you split a signal to 3 coherent sources, you get a 9.54 increase in dB. So, by adding the LFE to the LCR, you almost increase the LFE by the 10 dB amount that is required. I added an extra .5 dB when mixing the LFE to each speaker for a 10.04 dB total increase. Close enough. This was then verified later with the Omnimic measurements.

All that was left was to put a 16 Hz High pass on the LCR, mute the sub output to not cause any downstream headroom problems in the receiver, and add a single PEQ filter. I think I had to pull the output down a little at 20 Hz, but I'm not sure.

All of these settings are realtime and changes can be instantly viewed with Omnimic.

I can't remember if we did level/delay settings in JRiver or just left the settings in your receiver.

PEQ will add hiss anytime you run a plethora of filters. The more you add, the further up the noise floor creeps. What are you filtering to begin with? It doesn't appear to me you have run sweeps yet, so what are you even basing these filters on?

Dave did you switch back to the 4520 for power yet? When having ANY type of issues, eliminate as much complexity and as many variables as possible. If you insist on keeping the inuke in the chain, disable ALL of the PEQ/DSP functions. My guess is you either have some conflicting filters or crossovers engaged.

What filters are you using? If you add any gain in iNuke without first reducing overall level you can clip the signal. Digital PEQ doesn't change the noise floor unless you are modifying the entire signal which nobody does. The noise floor always stays at the same level and some frequencies that have been modified by the PEQ can now be closer to the noise floor. The A/D and D/A conversion can increase the noise floor and improper levels within the DSP. I have an oscilliscope and an iNuke nu6000DSP here and may post some stuff if I get around to it. I haven't even opened the nu6000DSP yet.

So, by adding the LFE to the LCR, you almost increase the LFE by the 10 dB amount that is required. I added an extra .5 dB when mixing the LFE to each speaker for a 10.04 dB total increase. Close enough. This was then verified later with the Omnimic measurements.

All that was left was to put a 16 Hz High pass on the LCR, mute the sub output to not cause any downstream headroom problems in the receiver, and add a single PEQ filter. I think I had to pull the output down a little at 20 Hz, but I'm not sure.

All of these settings are realtime and changes can be instantly viewed with Omnimic.

I can't remember if we did level/delay settings in JRiver or just left the settings in your receiver.

Trust me on this one DD, compared to the Rane, it's complicated and for now it is essentially unusable. How about (I'll compensate you for your time ) you remote desktop in and fix whatever it is I broke?

I need a quick primer and it would be worth it to me.

If you allow spare headroom for DSP, that would raise the noise floor.

I don't have any audible noise with my 212s, even at a couple inches, through either the Parasound A51 or the Hypex NC400 amps. I'm running balanced XLRs from the pre-amps. The difference could also be environmental.

As for movies, again, I like the 215's better than the 212's as they seem to have more presence, like the wall of sund they emit seems epic at times .

It sure seems like Reef is having other issues in the chain. The good with music and not with movies thing never sits well with me, like Forlich says, a good speaker is a good speakers, if it does one thing well, it will do everything well.... until it's limits of course.

I agree with Nathan, I think the 215's are better at everything - EXCEPT - for those that have a very well treated and large room. In that case you might run into limits of the 215 if you like to watch movies over reference.

Looks like I'm the only guy that thinks the 215's have MORE energy in the upper frequencies, I'm not talking about the harsh stuff around 2-4khz, but the frequencies above 8-10khz which to me sound pleasing not harsh. It's the same CD so it makes no sense but that's my impression when I compare the 212 and 215. The highs on the 215 are more pleasing to my ears and seem to have more sizzle (sorry, don't know how else to describe it). This is why I'm surprised that Dave is hearing a muffled sound with the 215's for movies, the opposite is true for me.

For music it's a bigger difference in favor of the 215 IMO.

I still love the 212 though, don't get me wrong it's a great speaker.

Actually, the 212's with well integrated subs are the equal of any system I have heard for movies at the main LP. For music, the 215's run full range (in the right room) from the LP are something special. If the dynamics are less with the 215RT's, it has gone unnoticed by me .... I think Jeff might be trying to discourage some from going with 215's due to setup complications. They are not plug and play speakers and it takes s little more work and setup to get them optimized.

There are many factors at play here and getting the speakers setup properly is job 1. There should be no hiss or hum coming from the speakers. Have you (Reef) tried the 212's with the current setup to see if you have the same or more hiss/hum?

Update, I do find that I run the 215RT's 2 (+/-) db louder than the 212's for action movies. That may be due to a slightly softer top end ...
The hiss is from the PEQ. I shut the PEQ off last night and reset it and the hiss disappeared, the speakers were silent. I also have no hum.

I have not done sweeps yet. I have been short on time and have just been fooling around trying to get an idea of the Inuke DSP. I was adjusting the PEQ by ear in the 10K range to get a little more top end. Just boosting the DB's in the PEQ gave some more top end. I find these speakers with the inuke with no eq and the PEQ off sound dull and flat. But yes I will agree the PEQ will add some bad hiss.

Not to sound sappy but I took all 3 of my pooches to the vet yesterday for test and shots and my older dog had a reaction to one of the shots. Around 4pm yesterday I was walking out the door and the dog was on the floor screaming in pain. We have been dealing with this all night and this morning. I cannot even pick the dog up and move her with out her screaming, it is really messed up, my wife is freaked out. So I got her to the vet this morning and she got a shot and she is now sleeping it off. I am really hoping to get out there today and sit down and just get some sweeps and some tinkering done. Not to mention my finishing work in the room. I also did a bone head move. I added the amp without putting the AVR amp into Pre out. Thats was my shutting down problem.

As said just tinkering with the PEQ a little to get some more highs. Being new to the DSP there are million buttons and just trying to get a feel of what they all do.

Dave, do you have acoustic treatments in that room yet? If I were you I would drag those 212's into the room and see if it's just a different room that's got your ears off kilter.

Yeah at some point, I gotta get some other stuff done first and complete the room. I was excited to hear the 215's, but I want to get the work out of the way and then I play.

I know this it OT, but it has bass I have been thinking about a Mustang build and came across this. There is quite a few videos of this car, but man do I ever want a stang now. There is a black GT sitting at lot right now I have been drooling on. Hmmmmm

Reef,

I am anxiously following your adventures with the 215's as in a month I'll have mine. I think one good thing I have going for me is that I don't know what the 212's sound like so I have nothing to compare them to (even subconsciously) except the Mac's I currently have and I've gotta believe the 215's will blow them away. My plan is to insert them in place of the Mac's and change nothing else and see what they sound like that way....well I will run them 2 different ways....full range and x-over'd @ 80hz....just like I have now. When I run them full, my processor will route LFE and all bass below x-over to them. (the 215RT's). So that will be my plan and I'll go from there....and I also plan on buying an Omnimic as I have nothing now to tell me what's going on in my room. I'm really interested in FR and decay in my room.

Keep sharing.

Yeah it is pretty sad, my wife is really upset over it. We are unable to touch her. I have had her up walking to go outside a couple of times but mostly she has been in her bed enjoying the drugs That is an improvement over last night as she was just screaming all night, I thought when I took her to the vet this morning they might put her down, it was that bad. But she is home safe now, doing a little better.

You may have yours by the time I get mine figured out . Problem around here is everybody makes it seem easy


Anyhoo, I have been out working on my mounts for the S8's. I have been at it awhile as I just cannot get the keyholes lined up. I have measured and measured and yet when I look at the screws they all seem to be short of the stops. Me and my daughter did a stencil with wax paper and I did a dot with a sharpie and then transferred the stencil to the back of the S8, but they still seem like they are all not on hitting the top of keyhole I am afraid they are going to come crashing down. I thought about doing two screws. I used 1/4 ply with 1" #12 screws. When I hold the S8 in the air it feels solid, but again the screws don't feel like they are lining up. What do you guys think.
