    Sorry, I don't know how to do the KP7 trick.

    I purchased a set of Klipsch KG4 loudspeakers at Tweeter etc. They
    list for $600.oo for the set, but you can buy them for about $500.oo
    For the money, I believe they are about the nicest all around speakers
    available, however, your ears may prefer something else. I also
    looked real hard at Celestion, Boston Acoustics, B&W, A.D.S., Polk
    Audio, DCM Time windows, and a number of others. For overall sound
    quality I prefered the Celestion DL10 but they cost about $700.oo
    (list price). The two main selling points on the Klipsch are the
    cabinets (choice of several different veneers, No vinyl veneer on these
    babies), and also the components (drivers and crossover networks)
    can stand up to any of the competitions' components. One other selling
    point on the Klipsch speakers is the efficiency, and with only 35
    watts rms power, this may be your most important concern.
   
    As was mentioned in .1 you should check through the audio notesfile
    for more information, but also go out and listen to as many different
    loudspeakers as possible, and do A B tests by comparing them with
    other speakers on the fly, in the same listening room. Just for
    fun try comparing different speakers with your eyes closed, so that
    you are not influenced by cosmetic appeal. Above all, don't make
    a rush purchase. Take your time. Shopping for speakers can be fun,
    unless you find that everything you want is way out of your pricerange.

    I am considering buying a new amplifier (Seymour Duncan), and it
    comes with a choice of speakers by different manufacturers.
    Unfortunately, there aren't many stores in this area which carry
    these amps, so I won't have an opportunity to compare them. I'd
    like to get some feedback from other noters who might have some
    experience with these speakers in this or other amplifiers. The
    options are:
    
    	Seymour Duncan		(no additional charge)
    	Celestion G12K85	($80 extra)
    	JBL G-125		($160 extra)
    	EVM 12L			($165 extra)
    
    The amp I have tried has the Seymour Duncan speakers, and I was quite
    impressed with the sound. I was told by the salesman that he had heard
    the amp with the JBL speakers in it, and didn't observe any significant
    difference in the sound. The thing is, if I am going to put out big
    bucks for this amp, it's worth a little extra to get the best possible
    sound.  But if there is no significant improvement over the sound of
    the Duncan speakers, why go with anything else?

    Ram,
       Electrovoice and JBL speakers have always been known for their
    clarity. EV's have a higher (at least they used to) power rating
    than your standard JBL-12". Most EVM-12" can handle 200 watts easy,
    although (to my ears), tend to have a slightly flatter sound if you
    compare them to a JBL. It all goes to the sound you want. Fenders
    used Jensens and JBL's. Ampegs had Altec speakers as an option
    many years ago. Great clean sounding speakers, but would crank well
    when you wanted a cranked sound. Electrovoice speakers seem to be
    used more and more these days. I use EV's and I think they're great!!!
    Very heavy (1 ton) speakers, but great sounding plus the fact that
    it takes alot to blow them. Come to think of it, I haven't heard
    of anyone blowing an EV speaker. Celestions on the other hand, have
    a totally different type of sound. You want a R&R sound with a touch
    of metal ? Celestions are the way to go. They crank easier
    than any of the others mentioned here. They also have a very nice
    sound without the distortion. A much smaller voice coil than the
    EV's can make these speakers sound great clean, BUT add a bit more
    volume to them and look out. To say they crank is not the word.
    To say that they are good only for R&R would be incorrect here though.
    I have a friend on N.Y. who plays jazz in different clubs and plays
    with celestions. His sound is very clean. I guess you could say
    that celestions have a singing type of distortion that a bit easier
    to get when you want it compared to the EV's and JBL's. 
      Just MY opinion here. What tone I may hear is one thing, you might
    think differently, but it's just my opinion. I don't know what speakers
    S.Duncan is using as a standard speaker, so I can't help you there.
    I've however used JBL's, Altec's and EV's so I felt I could comment
    on this note. Your own ears are again your best judge.
    
                                     Have fun Ram,
                                                   Fred

    
    Celestions come in various wattage ratings now. From their 25wt
    speakers to their 150wt sidewinder series. The sidewinders are very
    reminiscent of the JBL's, and it takes a lot to overdrive them.
    they're also very transient-efficient...they'll rip your head off
    if you're not careful. For real rock n roll, the trend is the 25
    and 35 watt celestions with a powerful (100WT or so) amplifier.
    The speakers distort and flap in the breeze and you get *the* sound
    of rock n roll!
    
    

    Celestion is now selling a Vintage 30wt guitar speaker that is
    supposed to spec closer to the original 60's G12 speakers.
    Anyone hear these yet?

    I went ahead and got the Seymour Duncan with the Seymour Duncan
    speakers in it. According to the sales rep this is actually made
    by JBL, they just OEM it. They used to get them from Celestion,
    but he says they had a QA problem so they switched vendors.

    On the question of sound, he claims the Celestions are great if
    all you ever want is a straight ahead rock sound, but if you ever
    want to do anything clean you are out of luck, because they tend
    to "flap in the breeze". I din't get the opportunity to compare,
    so I can't say.

    	I have a question concerning speakers for guitar amps. I am
    in the process of installing a Celestion G12M-70 in my amp. The
    current 12" speaker is an 8 ohm and the Celestion has a 16 ohm
    impedance. I have a switch on the back of the amp for switching
    to 4, 8 or 16 ohms so installation should be no problem. The 
    question I have is, will changing from an 8 to a 16 ohm speaker
    have any effect on the output of the amplifier? (ie. volume, signal
    to noise levels, etc.)
    
    Thanks,
    Don

    No it doesn't usually have an effect. Changing impedance is usually
    required for tube amps (I assume this is a tube amp). Tube amps
    are very sensitive to the load impedance, if it's wrong the output
    transformer usually begins to melt/burn due to reflected power.
    The output transformer has multiple taps to allow speaker combinations
    of different impedance to be used without damaging the output
    transformer. The output power to the speaker is the same.

    Well, I have noticed that if you are running a half stack @ 16 
    ohms, and you rewire the cab to 4 ohms (changing the amp imp, of
    course) you get more low end rumble out of the cab it seems.
    i also have friends who run their marshall heads at 8 ohms into
    a 16 ohm cab and they say they like the sound.  In my mind, it seems
    you'd get relective power if the resistance was greater on the cab
    than going out the head, but what if you were running 16 ohms out
    of the head into an 8 ohm cab?? I know any mismatched imp will not
    be functioning at 100%, but would it have any adverse effects on
    the head?
    
    wjb

    if you run 16 ohms at the head into an 8 ohm load, you'll try to
    drive more current into the load than the amp was designed for.
    Tubes are essentially voltage transforming devices (gross simplifiction
    here) so when you 1/2 the load impedance you increase the current
    into the load for the same output voltage.  The most likely result
    will be a fried output transformer from too much current in the
    windings.

    Does anyone in here use the BOSE 801s (The black Pro versions of
    the 901s)?
    
    I'd like to hear some opinions on using them for guitar applications.
    
    Thanks,
    Mike

    
    I've used them for PA applications, amplifying acoustic instruments.
    They sound very clear and more detailed than most PA speakers, but
    they require more power and for heavy bass you need a couple of
    pairs of them.

    If what you want is to reproduce *acoustic* guitar, they would most
    likely sound good to you.  For *electric* guitar?  Well, maybe if
    you were using some sort of hi-tech rack setup to drive them, I
    doubt the tone would be too pleasing when used with a typical guitar
    amp head.

    Re: .11
    
    Bose is also now marketing a new AcoustiMass speaker which is self
    powered by a 400 watt digital power amp.  The entire thing is in
    a molded enclosure roughly 18" cube.  

    I should be getting a demo soon, my next-door neighbor just was
    put in charge of all Bose pro audio engineering.

    For sure Brian!  I have an old friend that works for them.  He helped
    me get my home speakers at their employee discount.  Too bad they
    won't let employees buy pro products unless they are in a band.
