A minidsp would be all you would need but I prefer the dsp of the inukes for the speakers so if it were me (and this is what I did) I'd get an inuke to power the 215's and a minidsp for the subs.

Well, then you also need a mic to measure the response and a laptop to have the mini and inukedsp hooked into. It makes it easy to watch in real time the changes you make to the dsp and how they affect the frequency response. 12 db slope crossovers and high pass filters work very well in my room.

If I get invited and get to attend...I should have my pro quality microphone and preamp/interface figured out by then and I'd love the practice of taking measurements. If not I know many have USB microphones or the Dayton Omnimic and I'm sure someone would take the measurements.

For measurement equipment I'd recommend either purchasing the Dayton Omnimic V2 system (includes SW and mic) or purchase a CALIBRATED USB microphone (UMIK-1 or UMM-6) from Cross-spectrum.com and use with the free Room EQ Wizard (EQ) software, which you can download from HTShack.com.

Find a link to the old system? And if you do, you could probably make a lot of money as I'm sure many would rather revert. But sorry, I just looked too and I couldn't figure out any way to do it. Another bit of lost functionality.

I saw those when searching eBay for a used JBL 2226H. They must be 8 ft tall.

No doubt. That top horn is perfectly aimed to nail the sweet spot on that couch you have mounted 6 ft. up on the back wall of your living room. .

I had dual Orbit Shifter LFUs. I was planning on keeping one just for movies, but so far I don't see the need. The 215s put out an incredible amount of bass. I will need a new amp, because the clip lights on the crown xti 2002(800 watts into 4Ohms) is flickering at times. I have been listening to mainly music so far, although I did watch the new Captain America the other night and thought the bass was more than adequate.

I thought the same thing when I saw them...they don't look so imposing. Your room must be big.


How did you mount the 215RM on the wall....I'm sure that's a beastly speaker as well?


What are you using for surrounds? JTR's?

Man, impressions are tough this early. Last speakers were 212HTs and dual orbit shifters, and like most here I have had a good amount of speakers through my living room: Infinity, Triad, JBL, Quintuple 8's, Yorkville Unity and a couple others. I also am using Audyssey on my Onkyo 5508, so that is another variable. Although the measurements on the Omnimic say I have the responses very similar at this point. I also am using the dsp on my crown xti 2002 for the first time. And if that isn't enough I installed GIK acoustic 242 ceiling panels, as you can see in the pic. I did listen to the 212HTs with the panels, however I did not rerun audyssey after installing them. I believe I'm at the point/speaker level where room, setup, and EQ to my preference will make the most difference. I think the 215s are quite different. Slightly less clinical and warmer would be my initial opinion. Maybe that is ever so slightly more laid back? Now the bass is quite different as well. This could be due to using the dsp to raise bass levels as opposed to raising subwoofer output. This allowed me to raise mid bass as well without the crossover to the sub being the limiter. The mid bass is better, but again maybe due to the dsp work. The interesting thing is the imaging is improved as well. This could be a result of the ceiling panels. So, not sure any of this was helpful to someone trying to decide between the two. I am very interested in your opinion of the M2s after you have had some time with them. I almost went that direction myself. After all two 212s and two orbit shifters is the same price as the M2s without amps. Although I would probably buy them with the amps.

When you have to fit a speaker as big as the 215RM in your living room, and your married, you have to be creative. I built a custom recessed shelf for the 215RM into the space above the fireplace. I also did the stone work, which she wanted, so win win. Surrounds are Single 8LPs.

Great job. I was going to say...there's no hanging the 215RM on the wall like that. Beautiful work!

I would take the advise of Mr Carp and just get the Inuke 6000. I ordered the 3000, but I think I am going to move up the the 6000 and put the 3000 away for a spare. Who knows.

Yea, it's not on the site yet. Essentially it's a chopped down 215RT. Big differences are it's sealed, and is not full range. Measurements show it goes down to 40 no problems. So far it proves to be very good for center channel duty.

Changing the subject here as I often do. I got a hell of a deal on a tv today. I'd been looking for something to replace our 42 inch lcd upstairs and it looked like to get a good non smart led lcd you had to spend around 700 for a 55 inch.

Well, I recently found a deal on slick deals for 499 for a 55 inch lg lcd 2013 model at microcenter. It was one of those things were microcenter doesn't advertise that price but if you click on email me the price the email shows 499. So I called microcenter today and of course they sold out in less than a week after offering 499.

I went to Nebraska Furniture Mart and they didn't have the 2013 model anymore so no go. I then went to walmart and sure enough they still had the 2013 model but for 599 instead of 499. I asked a worker if they could price match and he said only if it's a printed add from another local store.

So, I went up to the electronics counter and figured I'd ask there too. I asked and the girl said the same thing about how it has to be a printed add but she sounded unsure of her self. I told her I had the email from microcenter that showed the price and while I was showing it to her on my phone a lady in line behind me came over and quickly and confidently said, "oh yeah, I've done that all the time walmart always matches those emails". The young girl was already flustered and quickly said, "ok, yes we can match that". The lady in line gave me a big wink. The worker called a manager over to authorize the sale. I figured he would call bs but he looked all jaded and uncaring and quickly typed in what needed to be done and left.

So, I got the 2014 tv for 499. The kicker is when I got home I realized that it wasn't the 2013 model that was on display in the store and the one that microcenter put on clearance for 499, instead it was the new 2014 model (the girl had to go the back to get the tv there weren't any boxes left by the displays).

I just checked online and the cheapest I can find the 2014 model is 679 on Amazon. http://www.amazon.com/LG-Electronics.../dp/B00KVLT08G





I feel a bit guilty since it wasn't legit but oh well. The tv looks awesome, the picture quality destroys the LG 42" we had before. That one will be going on our screened in porch.

Ha Ha, thanks Carp. Quick question for you. When setting the gains on my amp do I want the input and output to clip at the same time. Right now the input is clipping about 5 db before the output.

You don't want any clipping at all on both the inputs and outputs.

I have it set up so that the output clips just before the input does, but the way I understand it they don't have to be that close you just want to make sure the input never clips so the output can clip long before the input clips.

So, I would change your settings so that the output clips first.

True, but eventually something has to clip if you are going crazy with the volume right? When pushing the limits one of 3 things happens.

1. You clip an amp.
2. You damage a speaker/sub.
3. Your ears give out first.

Ahhhh you must be referring to #3 !
