Heights are the way to go,try playing a movie with rain or storms it really adds something to the movie imho,someone answer this for me, could I remove my 2009 triple 12 cd & 12 in woofer and replace it with a horn with the cd attached to it or would I have to change the x-over.Also would it be hard to find a horn to fit in the 12 in woofer space? thanks

Your only real option is to update your T12s to the current CD and XO. The BMS CD is a nice upgrade.

There is no horn I am aware of that would fit and you would have to change the XO if you could. It would be more trouble then its worth.
Good luck

edit: there appears to be a ground lift toggle on the rear of the A51 looking at the pics on Parasound's website.

Both the Halo amps have the ground lift and both are turned on. I still have a tiny bit of "noise" you can hear when you get close to the speakers. The A23 has a gain dial and if you turn it down from max the noise dissapperas for those two channels totally. That makes me think when I put the attenuators on the 5 channels from the A51 that their noise will dissapear as well. Thats my story and I am sticking to it.

Although I only have a very slight buzz still that you literally need to be within 4ft to hear with nothing playing I'm still trying to get rid of it. So last night I switched out my RCA to RCA's going from my receiver to my Sherbourn amp over to RCA to XLR cables. The buzz was reduced even more, now you need to be within 2ft to hear it. Next week a buddy is going to bring over his Sherbourn receiver that has XLR output so I'll use XLR to XLR cables to the amp to see if this completely gets rid of the buzz.

If it does I see a new receiver in the very near future smile.gif

Awesome. I was just busting chops, if you're happy with the AVR then maybe you don't need an amp.

On a serious note though, I ran across a maintenance manual for your AVR in case you decide to keep it long term http://www.wikihow.com/Care-for-Gerbils biggrin.gif

Most people don't know this but the leading cause of ground loop hum and other unwanted noise are AT screens tongue.gif

LOL.... oh is that what it is, in that case you definitely don't want the awesome feeling of the sound rushing threw the screen at you. Stay well away for an AT screen then!..lol biggrin.gif

Oh Rich has the masking panels coming out for his Falcon screens in the next week or two, looks like they're going to be almost a $100 less then what SeymourAV has too.... just sayin tongue.gif

I wouldn't expect anything less wink.gif I am thrilled with the sr7008...my ONLY logical reason to get the 8801 would be for the 4 ohm rating on the 212...even though marantz did confirm the sr7008 supports 4 ohms...ok, 2 logical reasons...I've always been partial to having separates if possible to keep power and processing away from each other, and the overall theoretical approach of minimizing interferences in these area. I'm not afraid to admit I'm guilty of wanting bigger toys in the HT/music department...been waiting for 20 years, so why not, right? cool.gif

Thanks for the manual!

Thought I'd share...Amazon is having a sale on lots of blu-rays for $5-$10, with lots of popular ones around $7. Just picked up a bunch, including even a Led Zepplin concert: List of Titles

i was able to convince myself that the LG was in the need category to drive the 215RT's. It was uncomfortable thinking that I might not hear all they have to offer due to power. If it works out, I will probably sell the W4S and bring in something else for the surrounds.

No doubt. The 215's are clearly in the need category as far as I'm concerned. No need to to lean on theoretical headroom arguments with those. biggrin.gif

But I have ever so briefly considered the 215's, so in that case I would need my amp. So Archea, on second thought I won't be needing that switcher. tongue.gifbiggrin.gif

Are the LG's as loud as the clone amps as far as fan noise goes?

Interesting discussion about height speakers. I haven't tried the heights yet, but I did find that adding wides was simply amazing! I use audyssey DSX and it's like sitting in a bubble of sound. Pacific Rim is by far the best sounding bluray I've watched. By far.

It could be that in my narrow 13' room, the wides make a bigger impact.

Of course, source material is important. I'd be interested to know what impact the heights make to pacific rim.

For what it's worth, I like audyssey dsx better than neo x.

Yes they are. I think RMK made the right choice to go with the best right from the get go. Same reason I got my crest 7.5. Jeff said these need some power to rock.

Thanks for the heads up man.. I've been wanting to pick up some concert blu's but always end up buying movies. I'm ashamed to say that I've NEVER listened to a SINGLE song on the JTR's unless it's in a movie..

Rob told me he hooked up his new LG to his alarm clock until his 215s arrive. Told me it woke him up this morning like nobodies business and he actually "did his business" by accident because it was so loud. The alarm clock speaker came dislodged from the clock and shot through the window.

Lol. There is nothing consumer about these amps. They are designed to be "behind the stage" with maximum longevity and reliability. What it lacks in heat sinks it makes up for in air flow. I'll never get rid of this amp.

Yeah, this amp will probably out live me. As to the noise, I have a separate equipment closet so I'm not worried about noise. However in the current config (powering the alarm clock) on the nightstand, it is very annoying.

A little off topic here, but I know some of you guys have went with an AT screen. As some know I am trying to have a theater built, but it has not been easy getting someone to do the build. I now finally have a quality builder and the ball is finally rolling and hopefully next week I may have some progress.

My question is, I have decided to go with an AT build with a front stage. I was originally going with no stage with a fixed screen, but have decided to go AT with a small speaker room behind the screen and simple stage. I might as well just do it while I am doing the build because I will just wish I had one 2 months down the road. If I do go for it, I will have about 9' to 10' viewing from my chairs, will this be to close?? 10' will be about the best I can do and I am worried it may be a bit close. Anyone sitting that close??? Will the projector work that close?? Yeah, noob theater questions, but I know most of you guys are all set up already. I appreciate the feedback.

JTROSmeasurements.pdf 937k .pdf file
Hello All, after selling my Submersive HP I ordered an OS in December and received it a couple of weeks ago, I have it located in the center of the wall underneath my big screen, I have a Marantz AV8801 so I ran some measurements old school style via a RS analog SPL meter, a test tone CD that i had burned in 2008 and recorded to an excel subwoofer spread sheet that Ed Mullen emailed back then when I had dual PB13 ultras. I purchased a new laptop at Christmas so i will download some software and purchase a mic maybe next month but that's a whole other subject. My main question is that the difference that Audyssey XT32 made was substantial. I have attached the graphs via a pdf file that I scanned to my computer, after seeing and most of all hearing the difference it made I am a believer,problem is I may sell my AV8801 Marantz to possibly purchase a Krell foundation pre/pro as the reviews are phenomenal and I may want to try it out, it doesn't have Audyssey however so I am looking for opinions as to what I can purchase that hopefully would make as big a difference as the XT32 has, I have read good things about minidsp and the anti-mode 8033 but again if I go the Krell route I would want something to help the bass hopefully similar to or even better than XT32, any advice would be great, thank you all.

Hello All, after selling my Submersive HP I ordered an OS in December and received it a couple of weeks ago, I have it located in the center of the wall underneath my big screen, I have a Marantz AV8801 so I ran some measurements old school style via a RS analog SPL meter, a test tone CD that i had burned in 2008 and recorded to an excel subwoofer spread sheet that Ed Mullen emailed back then when I had dual PB13 ultras. I purchased a new laptop at Christmas so i will download some software and purchase a mic maybe next month but that's a whole other subject. My main question is that the difference that Audyssey XT32 made was substantial. I have attached the graphs via a pdf file that I scanned to my computer, after seeing and most of all hearing the difference it made I am a believer,problem is I may sell my AV8801 Marantz to possibly purchase a Krell foundation pre/pro as the reviews are phenomenal and I may want to try it out, it doesn't have Audyssey however so I am looking for opinions as to what I can purchase that hopefully would make as big a difference as the XT32 has, I have read good things about minidsp and the anti-mode 8033 but again if I go the Krell route I would want something to help the bass hopefully similar to or even better than XT32, any advice would be great, thank you all.
My advice is that I would take minidsp over audyssey if I had to choose one. I actually didn't like what audyssey did on my sub and fixed it with the minidsp.

My question is, I have decided to go with an AT build with a front stage. I was originally going with no stage with a fixed screen, but have decided to go AT with a small speaker room behind the screen and simple stage. I might as well just do it while I am doing the build because I will just wish I had one 2 months down the road. If I do go for it, I will have about 9' to 10' viewing from my chairs, will this be to close?? 10' will be about the best I can do and I am worried it may be a bit close. Anyone sitting that close??? Will the projector work that close?? Yeah, noob theater questions, but I know most of you guys are all set up already. I appreciate the feedback.

9-10' sitting distance being close is relative to the screen size. For this distance, 110" 16:9 screen would be my max...but I would personally go 90-100" at this distance. it's nice to have immersion with a bigger screen when there's enough distance, but when you're that much closer, being able to see pixels come into play and how much do you want to turn your neck instead of just your eyes.

The best advice I can give you is to do what I am doing now in my room...experiment (this is why some of my speakers are sitting on cardboard boxes as seen in pics I've posted). Then measure twice, and cut once. Don't start construction until you have tried all of your options in your room. Take your projector and place it at distances you think you may hang it...every projector has variable throw, zoom, brightness, which will make a difference in your room and placement...Don't trust any calculators or specs you may have seen online...Verify for your implementation. For the screen, put nails on the side walls at different distances you're considering and make a clothesline basically...and throw a white sheet over and put some weight on the bottom corners to make it taut...then see what size looks good to you. You may be comfortable with something bigger or even smaller. Rinse, lather, and repeat if desired. Then order or DIY the screen size you want.

Btw, what projector are you considering or have? And are you limited in where it can hang?
