Acoustic Research

June 24, 2004

To Jeff Fritz,

I read your review of the Acoustic Research Hi-Res system. I own this home-theater system and love it. Unfortunately, during my move to Hawaii recently, many components were damaged. I'm having a hard time finding either a "certified technician" or a store that can give me the price of grilles and other parts, either on the mainland or in Hawaii.

The AR website doesn't work anymore. Do you have any info that could help me?

Nathan Contreras

I hate to break the news, but the last I heard was that Acoustic Research was out of business. They were owned by the Recoton corporation, but even their website seems to be down. The good news is that there are several sellers on eBay that seem to have some parts and accessories. I'd contact some of them with the items you need and see what shakes out. Good luck....Jeff Fritz


InFocus issues?

June 18, 2004

To Wes Marshall,

I have just read your review of the InFocus ScreenPlay 5700, and you don't mention the projector noise, fan, color wheel, or whatever. I have a 5700 ceiling mounted and find it quite noisy when there is no loud dialogue or music. My first 5700 lasted 12 weeks, stopped and was replaced. The current unit has 210 hours up in eight weeks, but it seems a lot louder than the original. Any ideas? Is it possible to surround the projector with an acoustic enclosure leaving space for air flow? I agree with your review -- the picture is fantastic and we particularly like watching the local Australian-rules football on widescreen through a digital STB. Check out the DVD George Harrison concert, and the R.E.M. concert in Germany. I would appreciate any comments.

My setup uses the 5700 as a rear projector, about 26' from my viewing position with a solid wall between, so my main concern is to check and make sure the projector is not terribly loud. If it is, I comment on it; if it is not, I don't. My version of the 5700 has been adequately quiet. In fact, the color wheel is amongst the most quiet I've tested. In terms of reliability, if I had had any problems with it, I would have reported them. I have had the projector over six months and have experienced no problems whatsoever. If you go back and check some of the other reviews I've written, you'll see that that has not always been the case.

Regarding air flow, I have the review sample dead against the back wall, sitting at the exact level it requires under the screen. Again, the 5700 is amongst the most quiet of the projectors I've reviewed.

Thanks for the tip on the George Harrison. I'll check it....Wes Marshall


ATSC or NTSC tuner in JVC digital recorder?

June 9, 2004

To Wes Marshall,

I enjoyed your review of the JVC HM-DH40000U. I have a question that you may be able to answer. I downloaded the user guide for this model from JVC and read it from front to back and it does not address my question.

Is the tuner in this particular model an NTSC tuner only? Or does it tune into ATSC broadcast signals and decode them? I live in the Dallas/Fort Worth area and there are seven live HD stations that I would like to tune into without having to go the satellite route. I do have my eye on a couple of Motorola ATSC receivers, but if an ATSC tuner is already built into the JVC, I won't have to purchase as many components for this system. I would love to hear your thoughts on this.

Max R. Friz

I wish I could tell you that the '4000 has an ATSC tuner. If it did, given its price, it would be one of the great bargains in electronics. As it is, you still have one of the best modes of time shifting available (outside of the few new DirecTV/TiVo hi-def DVRs) and the only way to buy a Jack Valenti-approved high-definition film. Alas, the tuner is NTSC only. If you do want to time shift high definition, make sure your ATSC tuner has a FireWire output that will work with the '4000 and remember that anyone from Food TV to HBO might put a block on recording at some time in the future....Wes Marshall


Lotsa processors

June 4, 2004

To Wes Marshall,

I've literally been going crazy trying to find the perfect processor for my home theater for over a year now. Cost being the most important factor, it's almost impossible to decide between a brand-new Outlaw Model 950 and a used Sunfire Theater Grand II, Proceed AVM 2, Proceed AVP, Meridian 565, B&K Ref 50, Krell HTS, or a Lexicon MC-1.

I just came across a new name (Fosgate) and after reading your review of it published in Home Theater & Sound and watching someone trying to sell it for $1200 on the Internet, I thought I'd check with you again if you had anything to add to it. How would you compare it against all the other big boys in the same price range (used)?

N.S.

I'm a licensed therapist, and I can tell you there is no cure for upgrade-itis. If you look back at my review of the Fosgate, you'll see a comparison between it and the Sunfire TG III and the Lexicon MC-1. If price really is the most important object, I don't think you'd be unhappy with any of the choices you mentioned. All should sound great.

If I were you, I would concentrate instead on the features and how well they fit your needs. For instance, are you interested in DVD-A or SACD? If so, you'll have to have multichannel analog inputs, and I personally, would like to see some form of bass management for those inputs. Only a couple of the processors you list can handle that. Would you like to be able to make system changes without firing up your TV? Then the screen on the Fosgate would be a big help. Do you want maximum flexibility in connectivity? Then the Lexicon wins out. If your goal is simply great sound, all have their benefits and the only way you can tell which fits your life best is to try them out in your home with your associated equipment.

I can't make your decision for you. But, given your list, if it were me, I would spend a little more and go for a new Fosgate....Wes Marshall


Monopoles for back surrounds

June 2, 2004

To Roger Kanno,

I have a specific question about THX 7.1. If I decide to go for Definitive Technology speakers, their surrounds are dipole configuration. For 7.1 channels, I read that the back left and right speakers have to be a monopole design. It's OK if the left and right surround sides are dipole. Why the switch to monopole for the back surrounds? Is it because you want the user to localize the sound in the back? Why the confusion? First they tell us that dipole speakers should be used for surround, and now they’re telling us to switch to monopole for 7.1. Would it be OK to use dipoles for back surrounds?

Renante Barroga

THX is now recommending monopole back surrounds placed very close together because of the difficulty in placing dipole surrounds behind the listener, which would usually result in some listeners being directly in line with the radiating faces of the dipoles and not others. The configuration of two monopole surrounds is designed to be used with Advanced Speaker Array (ASA) processing, which is part of the latest THX Ultra2 specification. ASA processing in combination with this speaker setup is said to provide a wide sweet spot for the back surrounds for all listeners while maintaining a diffuse sound (one of the goals of THX for surround channels). For this to work properly, the monopole back surrounds cannot be too close to the listeners. Dipoles can also be used for back surrounds, but according to THX, to prevent the listeners from being directly in line with any of the radiating surfaces, they should be placed very high above the listeners’ heads.

This is of course an over simplification of surround speaker placement and THX specifications, as it depends a lot on the configuration of your room and your preference for how diffuse or localizable you want your surround speakers to be whether you use all monopole, all dipole, or a combination of both types of speakers....Roger Kanno
