  1. I second all that. plus+++++++ I have lost count of the number of friends of mine who bought Heresy over the last 37 years after hearing my LaScala. They happily choose the babies of the Klipsch range. Place Heresy into corners and they are superior to a very many speakers of considerably larger dimension. My Dad had a stroke and to simplify things for Mum I removed my Marantz 1200B from their system and connected the Heresy to the speaker terminals on their TV @ 2 watts per channel. Along with the Blue Ray, I connected the CD, cassette deck, VCR directly to the TV and the Heresy make it all possible. I'm a Jub Owner and agree Here is a pic of a new 140db subwoofer during construction under a stage floor, that's in a system we finished last Thursday. While to some of my friends I'm a self confessed propeller head, I would have no reservation in having only a pair of any Heresy as my main system if that's what was most appropriate for my circumstances. Holy crap! The whole floor is a sub! Carl, are you seeing this?? This is inside the driver chamber which is a set of three 18" 800watt drivers on a triangular prism manifold which you can see in the other photo. The horn flare is 7m long with a 7m wide mouth.
  2. This is the mouth onto the sunken dance floor
  3. Your THT is a full Horn here is a set of three THT LP I modified a bit as a under floor experiment.

  5. Not your fault, the placement instructions were poorly written IMHO. This is a link to the BF site with photo's of my 1st experiment. It starts from the final installation and works backwards. You can see how the mouth is positioned 18" (out from the corner of the room), Note that there are 3 ways to achieve this. In this is case the speaker is wall mounted and pointing down towards the floor. The walls are brick and the floor concrete with carpet. http://billfitzmaurice.info/forum/viewtopic.php?f=5&t=17511
  6. You will get more out of the 684's when you relieve them of below 70hz. The 684's become faster as the ports are not doing anything. Be careful of your ears with the transients. Wearing ear plugs has become the norm at my friends hotel, lol. It's the feel of the music that blows people away and has them talking, though, I find it necessary to leave the room for a body break as continually being squashed make you tired.
  7. I'm using Chrome and I don't know what I'm missing if it's not compatible. I have not had any issues.
  8. Personally, I prefer the Dayton RSS390HF-4 15" aluminium cone driver. It's cleaner than the other recommended driver DVC385-88. The Rss390HF-4 was reproducing Cymbals rather well when I played music through it during breakin. I did not expect anything much above 800hz. The DVC385-88 is more sensitive but not as clean. The THT LP were all built in 24" wide 1/2 the width of a sheet of plywood except for a pair I built in 16" wide 1/3 the width of a sheet of plywood. For these 16" wide I used the RSS315HF-4 12" aluminum Cone Driver and they are also very clean. In 15", I have built a single a set of three and a set of two so as to experiment with the combined mouth sizes. The 7th & 8th were the pair of 12". The 12" pair are 16"x18" mouths, so you can add them together to create a combined 32"x18" mouth or a 16"x36" mouth. Currently they are set up as 16"x36" mouth and pointing at the ceiling with one wall on the 16" edge. When listening from the 16" edge performance is not wonderful. When listening from the 36" edge performance is fantastic. They are matched with my LaScala and I very much like the result. They have the LaScala clarity that goes out below you hearing when there is low bass in the recording. They don't invent there own bass like many other sub woofers that just woof woof woof. The THT LP are not boring they become essential. I like the shape 6' long as it's easy to place and point into a corner from any direction. I have finished my experimenting now and at the moment I intend for my Jubilee LFE to build a pair of 24"x18" with the RSS390HF-4 15" drivers and stack the along the back wall into the back left corner under the stair case 36"x24" mouth shape. The stairs are to be altered to be minimal and remove the risers having only the treads and stringers with two triangular treads in the corner then three treads to the floor. I trust this experience is useful in assisting with your choice.
  9. From my understanding this issue will be related to the location of the mouth in the room relative to the distance from reflective surfaces that cause certain wavelengths to cancel at certain positions in the room and only stopping the occurrence of the reflection can resolve this. Or move the mouth.
  10. Siri is two timing you, she takes shorthand for so many people no wonder she mixes things up, call me john the other day, how rude...
  11. In a friends hotel as an experiment, I built three THTLP with Dayton DVC 15" kevlar drivers to operate as subwoofers below four KPT-684. They are packed together to make a mouth 24" high 54" wide. The low end is now ridiculous. Just the way we like it. Using a bridged Yamaha P4500 nominal 12ohm. crossover 70hz to the 684 then 110hz to eight KP-362's.
  12. LaScala are visually striking and powerful. Then there is the Khorn and the Jubilee.
  13. In my opinion for when you must have a centre speaker the MTM format is a great option. Last year I set up a 128 seat cinema the room 40'by40' with a pair of cinema Jubilee for left and right and the KPT-4350 flying above the screen for centre. There is also a live stage in front of the screen so the LFE had to go on a shelf above the screen. I experimented with this setup for and entire day, learning, what was possible. In this case with 3way Jubilee, I used an Allen & Heath iDR8 10 channels in and out, with the OPPO Blue Ray driving the iDR8. For my home system, Jubilee 2way, I will be using an Ashly NE8800 8 channels in and out to drive the amplifiers with the OPPO same same. The point is:- I did not actually need the centre speaker. I created a "Virtual" Centre speaker in the centre of the screen by routing the centre channel into both the left and right Jubilee with a -3db gain reduction since there is two speakers rather than just one playing centre channel in this case. With the iDR8 and NE8800 and input can be routed to any output via the central matrix. Each configuration can be saved as a preset and recalled at the touch of a button for endless A/B comparisons. They include crossovers, time alignment, EQ, level matching, whatever. This was my plan for home and I had the opportunity to experiment with the Jubilee in corners 40' apart on either side of the screen. The result was simply "Exquisite". I blind tested all this on whoever was available and the virtual centre was the clear winner. Full Panavision Audio from invisible speakers. The soundscape extended out past the width of the Jubilee as if there were no speakers. I reckon proper corner placement of your main left and right and creating a virtual centre has the advantage of simple room treatments as there are less sound sources causing complex reflections and impeding your sound scape. I reckon a awesome home system does not need a receiver and has a speaker in each corner plus a LFE. That's 5 point sources which provides a completely effective triangulation for placing a virtual sound anywhere into the room. To include more channels causes more unwanted room reverb and diminishing the systems potential.
  14. lol.... Isn't this where Duke is supposed to chime in...? Miss that guy around here too. Bruce Super models in bathing suits would work just as well as children.
