    Hello my Klipsch family (Been awhile since my last post)

     

    Another receiver has bit the dust 😞…. So I’m back researching. I have always really liked pioneer elite Mcacc but, i’m now reading about this new Dirac Live.. all opinions are welcome.
     

    good to see you all! 

    Cornwall IV Bass Issues

    Home-sized rooms are not concert halls.  The difference is volume--dimension.  The reason for the "X" curve used in cinema (which itself isn't a correct curve to use, as it turns out) is due to the absorption of acoustic energy by the mass of air in these venues.

     

    I think it's good to have these kind of conversations online, but you really need to read and understand the engineering/physics body of knowledge on the subject of interior acoustics for live performance (i.e., generally very large venues) vs. very small home-sized listening rooms. 

     

    At the frequencies below the room's Schroeder frequency (which is dimensionally dependent on the linear dimensions of length, width, and height of the listening room, as well as the damping ratio of the sum of interior surfaces), the acoustic energy behaves like you're inside a chamber that is smaller in one or more dimensions than the wavelength of the acoustic waves, so the effects of toe-in, etc. have essentially nothing to do with the toe-in of the speakers below the room's Schroeder frequency.  So worrying about which way the loudspeakers are pointed means nothing below the room's Schroeder frequency as it turns out, only the distance of the loudspeakers from the mouths of the horns or the face of the woofers to the room's boundaries count, and if that spacing is less than 1/4 wavelength, it means that the way that the bass bins are pointed has no effects.

     

    However, at frequencies above the room's Schroeder frequency (generally around 200 Hz for most peoples' listening rooms), toe-in/pointing of the loudspeaker is very important.  So in general, the frequencies affected by tow-in and other aiming of the front baffle of the loudspeakers are the midrange and treble frequencies only--but not the bass frequencies well below ~200 Hz that the OP is talking about in this thread.

    Every time I read one of your posts Chris I learn a ton of stuff of course (thanks 👍).... And I’m also reminded of just how little I know (thanks 😉).

    Which is an interesting observation considering virtually all venues have as a minimum a concrete floor. And large concert halls/rock venues are concrete all around, and we tend to compare our listening experience to live music.

    This is true... But for bass in my experience in a home setting (with those rooms being much smaller then a venue). Bass IMO is humongous pain in the ***. The Cornwalls that I had on concrete (even in corners) compared to the living room 1 floor up on wood framed floors (not even in corners) was extremely different. 
     

    Others can chime in but it would be my guess that a room in a home setting might have more acoustic overall affect than a large space like a venue where the walls, ceilings and floors are normally a large distance away from the speakers?

    Reference line versus the Klipsch Pro Cinema line 🤔.  
    Theres another member on here that awhile back in describing the difference between a certain musician and another (can’t remember who he/she was) but his quote was something like (of course using speakers in this analogy). the reference line would be like someone painting a portrait using watercolor paint.... compared to that of the Mona Lisa (which would be the pro cinema line) IMHO 


    There’s a lot of things to consider. Where do the speakers go? How much does size and visual appeal based on one’s personal preference matter? Etc etc, 

     

    But performance comparison... it’s water paint versus Mona Lisa. But ignorance is bliss. If someone’s coming from something nowhere near what a top end reference line will give. I can’t imagine anyone being disappointed. Even coming from something better I still actually can’t imagine anyone being disappointed. Even though one is worlds better. 
     

    7s are no joke!

    Klipsch...50% off sale?  🤣

    The guy on eBay that sells the plaques (Klipsch and others). I sent him a message and asked him if he could make me one that said “effortless”..... to my surprise he sent me back a picture back “ like this?” 👍👍

    Hello all, my pioneer elite sc-55 has died so I need a replacement. 

    Budget 300-500 used probably best option Of course. But any gems that are popular in like a clearance on a online outlet store currently could work as well. I’ve been out of the loop as far as keeping up with gear and what’s what so any tips on the good values would be very helpful......

    Im in the Minnesota Minneapolis/stpaul area if that’s helpful

    Hello my Klipsch brothers been awhile 😊

     

    looking for a replacement for my sc-55 (may she rip). Would like something in the same class of quality and function, as well as Bluetooth would be nice addiction.

     

    My budget is around $500 tops. But 300-400 is about what I’m looking to spend.
     

    Also I’m not really up on what’s what over the last 5 years on gear. So basically even if you have nothing to sell please all tips and info are very welcome to post here .....

     

    I’m in the Minnesota St. Paul area
     

    thanks

    Yes, that's the one.  Highly recommended.  I have yet to have to install any extra gasket, but every situation is different.  I think you will enjoy the new woofer. Give it just a little time to break in, and it will surprise you with it's excellent speed and tone.

    Claude seemed confident the 15kappa c was la scalas best upgrade behind fresh caps of course. ( comparing to other low budget upgrades). 

     

    You agree?

    Grabbed a couple new pieces for my cabinet! Any Code 3 fans out there?

    I know Code 3 no longer has Star Wars rights but that is a real shame, these things are beautiful!af1868832e741ae55c346268212ad0f8.jpg856ed3f235432163beffe5384be652fa.jpg
