How do you personally shop for Hi-Fi speakers?
I'm not referring to just general principals of what to look for, I mean specifically what do *you* personally do when looking for speakers for recreational listening? Do you regard the listening rooms at Best Buy to be useless or do you think they're good enough to evaluate speakers/amps? Or is there nothing at Best Buy you feel is worth having?
Or do you just use studio monitors? |

I might start out thinking about a particular speaker manufacturer, then go look for a dealer that handles that line. But once I got there I would also listen to whatever other lines they had. And I would consider going to a stereo show, like the Stereophile show or the Rocky Mountain Audio Festival or the Capitol Audiofest in order to listen to a whole lot of different systems at different price ranges in a small time period. You can walk down the hall and see twenty rooms set up by twenty different dealers with twenty totally different philosophies. And then... whatever I am interested in, I would get on evaluation to try in my own room before buying anything. Or do you just use studio monitors? I might... but then it comes back to the same question, how do you choose them over all the studio monitors out there? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Several mastering studios use really expensive "domestic" speakers like Wilsons, though some have moved on to "pro audio" mastering speakers, some more expensive, some less expensive, most just as big and heavy. -- For a good time, call http://mikeriversaudio.wordpress.com |

The main speakers in one of the world's most famous recording studios are equally domestic hi-fi speakers, albeit a little on the expensive side. Exactly. Although one can make some generalizations, that studio monitors tend to be designed to be analytic rather than to hide faults with recordings like some home speakers. And they tend to be designed to be difficult to damage, as they are more apt to be abused by someone mispatching lines or sending blasts of feedback in the studio than they would be at home. Also, these days, studio monitors tend to be powered more often than not, and home speakers tend not to be, although there are plenty of exceptions to that rule too. I'm mixing on speakers intended for home listening and I have a pair of speakers sold for studio monitoring in my bedroom at home. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Or is there nothing at Best Buy you feel is worth having? ** Listen to demos in a shop is the WORST way to chose any hi-fi component. Many high quality speakers for home use exist, but none are cheap. There are also any number of genuinely famous or "classis" examples that can be bought on the used market - via Ebay etc. All depends of your budget and what you expect and need. ..... Phil |

Some requirements are that the speaker be fairly compact, suit being placed against a wall, accommodate a close listening position, be very rugged plus able to produce high SPLs when needed. This generally means having a good dB per watt rating. Studio monitors have to cope with uncompressed, live signals coming from microphones plus all manner of mishaps that create momentary huge levels. None of these necessarily apply to domestic hi-fi listening, so hi-fi speaker makers have a much freer hand their designs. The maker can trade off ruggedness and high SPL for higher accuracy and wider response range. The speaker may not suit wall mounting or close sitting positions. The only high quality speaker I am familiar with that is suited to home and studio monitoring use is the now classic Yamaha NS1000. For around US$2000 or so for a pair in good condition, it's the biggest bargain you will find. ...... Phil |

FYI: The only commercially made speaker I ever bought were purchased without a demo. There is not need to PERSONALLY to "demo" amplifiers, CD players or any piece of modern hi-fi electronics. And no point. The idea that a novice ( or anyone) can TELL with a quick, uncontrolled listen which audio item is best is 100% ABSURD. However, if you would like to own a *very* good pair of hi-fi AND monitor speakers - search out some Yamaha NS1000s. If you say you cannot afford them, you are not really serious. Go buy some ****-box, powered monitors made in China. ..... Phil |

So back to the original question - how do *you* demo speakers you haven't bought yet? I sort-of agree with Phil about this, in that you can certainly not make a final decision that way. But I think you have to listen to demos in the shop in order to get a sense of what is out there and just how wide the range of different sounding speakers is. And I do think that letting the salesguy take control of the demo is a bad thing. Bring your own material, make them play it on as many speakers as possible with everything else controlled as much as you can get them to do it. But in the end auditioning them in your own room is still needed. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

It had plenty of bass ripple, and the mid horns had plenty of resonances too. A waterfall plot would be very revealing I imagine. In fact I would have said that was a good example of the "wow factor". So effortless in producing a huge dynamic range, but far from "uncolored". OTOH I've heard many "uncolored" speakers that had no dynamic range and no bass that I wouldn't want to own. Trevor. |

Fraid I was singularly unimpressed. Sounded like an oversize stereo-gram to me. At the time, contraptions like the Bose 901 and Sonab's "omni" speakers were all the rage. I disliked them cos they were all *sound effect* producers, not hi-fi speakers. The marketing puke that backed them up was an insult to one's intelligence. ..... Phil |

First I decide how much I want to spend. Then I look over the literature for speakers in that price range, see what's been reviewed in a magazine or two that I trust, decide on two or three possibilities, and then try to find a store that has at least one of those available for listening. I'll bring in a couple of CDs, take a listen, and if it sounds OK, buy it. It's really not important to me to try to compare a few speakers.

It is amazing seeing how far we have come in the loudspeaker world. Frankly I don't think we've come any where near as far with speaker design as with most other areas of audio, excepting perhaps microphones. As you say the Paragon was pretty good, as was the Hartsfeild before it. Mid horn design and horn drivers have definitely improved since though. Now, by the seventies people were starting to power those things with solid state amps and discovering that when you put incredibly efficient speakers on early solid state amps that were biased way down into class B, that the crossover distortion swamped almost every other character of sound, and that gave a lot of these high-efficiency speakers a bad reputation. Listened to the Paragon *many* times, always powered by the JBL SA660, which was pretty good for it's day. But... the Paragons were one of those speakers that got used as home speakers, as studio monitors, and even in small PA rigs. The narrow angle of radiation reduced room reflection issues in bad rooms. However any corner horn relies on the rooms walls to complete the horn mouth. Unless your room was 9' wide, the Paragon had a far too small horn mouth for anything like flat bass response, nor even a steady roll off unfortunately. Still impressive however, but at a fairly substantial price for the day. Most new cars were cheaper here than the Paragon at the time. Hard to imagine it was more expensive to build. Trevor. |

I brought some of my own stuff with known problems. I heard those about right and bought them. I'd have rather had a nice 2.1 Blue Sky setup, but this was 1/10th the price and good enough. The only thing I don't like about them is that I am guessing what many car systems will make the material sound like in the mid bass. But I can work around that. Ideally, I'd put a sub on but I can't quite get to adding a sub just to simulate bad car audio. -- Les Cargill |

Looked at the whathifi links. Not a fan
of this trend toward lower impedance in home speakers these days. A couple 8s in their listings, but mostly 6ohm or lower. My 1995 JVC receiver specifies 8-16ohm, but it sounds alright to me, has Pro Logic surround, and is likely the last main listening room receiver I will ever own! I just hope down the road - knock on particle board! - I will still be able to find 8-12ohm speakers for it. |

Contemporary POPULAR(top-40, Hip-Hop, Country) music is so heavily processed it will sound like mush, whether played on a nice new pair of floor-standings, or my 26-yr old dB Plus 880 mains still in factory condition. And contemporary releases in niche genres, like acoustic, jazz, or classical, are exhibiting the same symptoms, more subtle, of such abuse, so, thanks but no thanks. If something sounds good, and everyone you have over the house says it sounds good, y'don't F with it, right ol pal? |

A given amplifier can put out only a specific maximum amount of voltage. This is limited by the power supply. A given amplifier can supply only a specific maximum amount of current. This is limited by the output transistors or (if it has one) the output transformer. For a given voltage, the current is a function of the impedance. Power is voltage times current (or voltage squared divided by impedance), and for a given speaker efficiency, power is what determines loudness. Efficiency can cover a pretty wide range. A 1940s Altec Voice of the Theater speaker can fill a movie theater with only 25 watts of power. A modern, highly damped, closed baffle speaker might require 100 watts to achieve the same SPL. The "lower impedance plays louder" alternative fact comes from the world of low power mobile devices. Your 1995 amplifier likely has a maximum output voltage of 30 to 50 volts, but your phone, which is powered by a 2.5 volt battery, has a maximum output of 2.5 volts. If you have a 100 ohm earphone, the maximum power you can get into that earphone is a bit over 60 milliwatts. If that earphone is loud enough for you at that power level, fine. But you'll probably want it louder than that. But if you have a 16 ohm earphone, you can deliver 400 milliwatts to it. In practice, you may not actually be able to do that because the output current of the phone's headphone amplifier is likely to be limited, both to preserve battery life and protect your hearing (and your earphones). However, there's a happy medium in there somewhere and, in practice, with a modern low power device, a low impedance earphone will play louder than one with a significantly higher impedance. As far as phones/updates go, I just don't do them - until a specific app no longer works on the device - which for me has been an almost nonexistent occurence. How old is your phone? I think the reason why most people don't have the problem that I'm having is that they're on a wireless plan that gets them a new phone every year or two, and they happily take advantage of that opportunity. I'm on the AT&T GoPhone (pay as you go) plan and my last "upgrade" about 2 years ago was a refurbished low-end Android smart phone phone for $35 that was already 2 years out of date. It worked great for a couple of years, but now there are many apps that, when I open them, give me a pop-up saying "There's a newer version of this app. Do you want to update it now?" When I say yes, more often now I get the message "this version is not compatible with your phone." I suspect that it's looking for a newer version of the operating system (like some Windows programs require Windows 7 at minimum and won't run on XP), and phone manufacturers rarely bother issuing OS updates other than security patches, because they expect their customers to get a new phone before they really need a newer OS. At least amplifiers and speakers don't constantly nag you to upgrade. -- For a good time, call http://mikeriversaudio.wordpress.com |

How do you personally shop for Hi-Fi speakers?

Efficiency can cover a pretty wide range. A 1940s Altec Voice of the Theater speaker can fill a movie theater with only 25 watts of power. A modern, highly damped, closed baffle speaker might require 100 watts to achieve the same SPL. I think you might have missed a zero there. Altec VOT a *lot* more than 6dB more efficient than any small "highly damped, closed baffle speaker". 100W ain't gonna do it. Trevor. |

Small AR style sealed box speakers rarely exceeded 86dB/watt. 20dB = a power ratio of 100:1. ...... Phil |

My post was just an illustration of one reason why the "general rule" is too general. But a good example of what many people do think regarding wattage requirements. They do not understand one speaker can put out less SPL with over ten times the input power. Or that it may not even be able to handle that power anyway, so can never match the 25W speaker. Trevor. |

The only thing most people understand is the angle the volume control is at when it starts to get loud. The further anti-clockwise, the more powerful the amp. Face palms all round, but that is the way it is. d --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Don Pearce:
I've heard of clockwise, counter-clockwise, but never heard of "anti-clockwise". What the heck is that? |
