Islander Posted January 16, 2011 Share Posted January 16, 2011 Looks cool, but I hope you don't notice too much comb filtering from the horizontally separated horns. Quote Link to comment Share on other sites More sharing options...
o0O Bill O0o Posted January 16, 2011 Share Posted January 16, 2011 cool, but you need a Lascala as a center. You've now go a host of acoustic issues to overcome. Anyways, you should be using an acoustically transparent screen or placing the TV ontop. Don't mess with the Center speaker Quote Link to comment Share on other sites More sharing options...
Wrench722 Posted January 16, 2011 Author Share Posted January 16, 2011 I dont understand? My RC-7 has two bass speakers. I set it up to match my two Hhorns. Quote Link to comment Share on other sites More sharing options...

TV will be on the wall over the speaker and the screen will droped down to the top of it. Don't mess with the Center speaker? Quote Link to comment Share on other sites More sharing options...
psg Posted January 17, 2011 Share Posted January 17, 2011 Interesting solution! I simply put my screen higher, over a regular La Scala. What's the circle cutout for? A roundHF horn? I wouldn't worry too much about comb filtering (even though I made that figure). The issue occurs listenning to music with left and right speakers as well when they get a mono bass signal. You can always disconnect a bass bin to see if it sounds any different to you. Quote Link to comment Share on other sites More sharing options...
psg Posted January 17, 2011 Share Posted January 17, 2011 LaScala are too big for a center. Debatable. I initially thought the TV would be too high and planned the joist spacing of the center front wall to accomdate moving the mid and HF horns over the TV. Didn't need to. It works for us, even more so when I add a second row of people watching a movie. Then the extra few inches of height are a plus. Of course a 50-inch display looks like it's 25 inches on such a wide angle picture! Quote Link to comment Share on other sites More sharing options...
Wrench722 Posted January 17, 2011 Author Share Posted January 17, 2011 The holes are for a JBL 2404 and a Trac Horn/Atlas Sound PD-5VH and Extreme-slope network. Quote Link to comment Share on other sites More sharing options...
Islander Posted January 17, 2011 Share Posted January 17, 2011 I wouldn't worry too much about comb filtering (even though I made that figure). So that's where it came from! Nice work, and it makes comb filtering much easier to visualize. Quote Link to comment Share on other sites More sharing options...

Nice work, and it makes comb filtering much easier to visualize. Thanks, glad someone uses it! A big part of my job entails making graphs, so coding that one up took minutes as opposed to hours.

chuckears Posted January 17, 2011 Share Posted January 17, 2011 Wrench722, It will be very interesting to hear about how this turns out... I have developed a hunger for a fully horn-loaded home theater, and have always come up with the center channel/height issue; I have thus far been leaning toward more of a "Cornscala" theory (with front-firing cone woofer/bass boxes sandwiching the mid/tweeter section), but this design intrigues me. Are you planning to bi-amp (or even tri-amp) this center? I have my doubts about an amplifier being able to handle two 15-inch woofers, along with the midrange and tweeter... I would tend to try a separate amp for each bass module, and one for the midrange and tweeter horns, but I am no designer or engineer.

It didn't use 15"s, but more like 10"s if I remember correctly.Bruce Quote Link to comment Share on other sites More sharing options...
IndyKlipschFan Posted January 18, 2011 Share Posted January 18, 2011 I use two of the doghouses left n right for the Center as well... With a split top between them.. It added a little more punch to the center, which was needed.,..I Love it.. And PS... A lot of Klipsch people have been to my house on here... and the "others" seem to as well, that have been over... Sometimes in HT it is a try it, see if you like it, deal.. I did, and STILL do. Stuff a lot of insulation around that horn in your cabinet to separate it all...from any vibrations to, or from, the Bass cabinets is my only suggestion... And IMO you will be set! The only issue might be the amp can it handle it? I use/have Sunfire.. never a problem there... RELAX>>> It will sound awesome! Just a thought too... "Comb Filtering" will occur where two loudspeakers are playing the same signal at different distances from the listener. Comb filtering occurs in acoustics. In any enclosed space, listeners hear a mixture of direct sound and reflected sound. Reflected sound, taking a longer path, constitutes a delayed version of the direct sound and a comb filter is created where the two combine at the listener.http://en.wikipedia.org/wiki/Comb_filter#cite_note-1'> So as a center channel, left n right of the separated top end in your case... They will be at the same distance to you... So not so much a problem. (If I understand this at all?) Quote Link to comment Share on other sites More sharing options...

If passive what is the impedance? I am interested in doing this. Quote Link to comment Share on other sites More sharing options...
IndyKlipschFan Posted January 19, 2011 Share Posted January 19, 2011 I split it at the top end.. sent same length spaker cables to the bottom right n left dog houses... + to + right n left... - to -....right n left.. Like I said it just added a little more punch but was in no way Boomy... Said to myself.. Sounds good to me.. so I left it there! Quote Link to comment Share on other sites More sharing options...
IndyKlipschFan Posted January 19, 2011 Share Posted January 19, 2011 I am a BIG TIME beleiver in the getting the La Scala tops about a milk crate above the doghouse though... Try this too... Quote Link to comment Share on other sites More sharing options...
