    It does look nice AND can double as a spot.....to keep your Glock....

     

    :unsure2:

     

     

    I just acquired one of those rotten things. It uses the same mags as a carbine I have.  Kind of a New West sort of thing. Despise the trigger.  🙂

  2. Gil and I exchanged e-mails, yesterday.  He said to say "Hello!" to all of you. 

     

    He is in a new facility in Chicago and finally getting PT.  He is able to do some walking with a walker and is getting more use out of his left hand.  He says it is slow progress, but I think it's grand!  His old phone quit working and BIL Joe has shipped him a new one, due this week.  Maybe he is a little harder on phones than some of us.  😉 

     

    I was getting concerned since he had been unreachable, but I think, now, that he's OK and getting what he needs.

  3. The K-700 makes for a nice sized lamp, nearly the same height as the ginger jar lamp that donated it's organs.  It is now on my nightstand and the extra area of the base is usable for some of the stuff I usually keep there.  A K-400, ..... hmmm?

  4. I would look at improving your room acoustics first (damp reflections and reverberation, the surrounds provide the intended reverberation).  Then, look at upgrading your receiver.  The RP-8000 speakers, at 98 dB/w/m will not challenge the power section of your Denon, so more power will only be noticed at very high SPLs.  The preamp and processor sections of your receiver make a large contribution to sound quality and clarity, more than the power amp, in my experience. 

     

    Adding a power amp to a receiver has become a fad, but I can't imagine why.  Seems like racing tires on a tired Yugo to me.

    For anyone who hasn’t heard about this, here we go.  The old cast aluminum K400 horns did indeed ring when struck, if it was out of the cabinet.  Once it’s secured to the motor board and supported by the bracket near the back end of the horn, the ringing disappears.

     

    I just tested a mounted K-700.  When struck there is a short duration "ting".  The K-700 is much shorter and has smaller wall surfaces than a K-400, making is naturally stiffer and less prone to ring. 

  6. At 21 years old, you probably do not need new/refurbished crossovers (maybe not even at 41 years, in my experience).  The sketchiest part is the replacement diaphragm and the skill needed to swap it out.  I've got a squawker that had an open voice coil and I paid a well regarded shop in Nashville (they had some of Charlie Daniels' amps in for repairs) to replace the diaphragm and it buzzes on piano after.  It was bought for backup, so I haven't tried to fix it again.  The work looks deceptively easy. 

     

    Your speakers only need regular use.

    Hello everyone.  Question, would Heresy IV's (Pair) make for a good center channel speaker or speakers?   I currently have the RC 64III and its beautiful but I have to increase the volume quite substantially for this center channel compared to the rest of my surround sound speakers to be able to hear the voices sometimes when watching a movie.

     

    Any input or suggestions welcomed....................Happy Thanksgiving to all.

     

    You should use the center speaker designed to match your front pair.  If your fronts are H IVs, use a 3rd for the center.  If the RC-64 III matches your front mains, get a sound meter and calibrate your system.  Sometimes movies are mixed so that dialog is not clearly audible.  That doesn't happen regularly in my system, but it does.  It must be a "style" for film makers. 

  8. On the floor and close to one, or more walls.  Distance to taste.  Most Heresies before the IV are a touch bright.  I think they need a subwoofer because the response below 70 Hz is weak.  I had 7 at one time.  Four helped me buy H IVs.

  9. Inspired by dtr20, I made a K700 lamp, of my own.  I used a die-cast K700 I'd bought for a stillborn monitor project.

    I had a friend turn a pair of adapters for the horn's throat and then cannibalized an old lamp a GF gave me 40 years ago.  The base is mahogany, bought in Chattanooga, planed in Huber Heights and finished with linseed oil at mi casa.  I could not see the figure in the grain until after it was planed and had to work a little to show it in the finished lamp.  The plaque was a gift from Hunter @JRH at the first pilgrimage, called "The Klipsch Fans Tour Of Hope".  I kept it in my Klipsch file folder for over 20 years until i found this use for it! 

     

    I hope Mr. Paul's soul gets a smile.

    I wonder what the odds are of finding some K-77-M's that haven't had their diaphragms changed out.  

     

    I can't tell, but it sounds like you are suggesting the K-77-F has the 5 watt rating, but it doesn't. Also, the K-77-F will only fit if the cutout is large enough. So, that would be anything where the Z-brackets were supported.

     

    K-77-Ms don't need the diaphragms replaced.  They came with the ribbon lead diaphragm that carries the higher rating. 

     

    Perhaps they were not -Fs, but the K-77-? I saw in the Lab would have fit my '81 LS.  The flange perhaps pushed the mounting screws wider, but wasn't definite.

    I currently have a Denon AVR that sounds great and does everything I need it to, but I've been seeinga lot of mention about having a dedicated two channel receiver. What's the benefit? also, is there an advantage to vintage 70's gear, which is all the rage these days, vs amps and receivers from the 80's and even now? 

     

    No.

     

    However, a good 2-channel amp/receiver will have a power supply with much greater reserve power capacity than your AVR.  The old Tanks of the 70's had to meet the FTC power rating procedure so the bits and parts were sized to handle more heat and the the PS was robust.  The old amps mostly had low Damping Factors and tended to sound soft similar to a tube amp.  I like the sound of modern amps with large DF better (crisper and with tighter bass).  To get both I went with all separates.  My power amps take a long time to go quiet when the power is turned off, demonstrating the depth of the energy reserves.  All that comes at a price, though.
