Hello, I am a long time Klipsch heritage speaker owner in my 2 channel set up but trying to get my first HT set up in my familyroom. I am thinking of going with RF-7ii and RC-64ii across the front but because of the room and WAF I think I'll have to go with in ceiling speakers for surrounds and/or rear. Is this going to work? Any help is much appreciated. babadono

Cool thread Cask05. Great idea. I have been a long time Klipsch Heritage 2 channel owner/listener, but unfortunately don't have multi channel HT set up yet. But I'm working on it. Pleae everyone keep the reviews coming. babadono

I can't find the "ANY' key

DrWHo/djk, Please do not take offense by my questions and comments. I am not in any way trying to be obtuse only trying to understand this. It looks like by your graphs DrWho that in the audible band the 2.2k resistor doesn't make as PWK used to say a "dimes worth of difference". Especially with the 100 ohm output impedance. Am I interpreting the graph correctly? babadono

DrWho, In both graphs there are two sets of curves, excuse my ignorance but one is amplitude and one is phase? Ok that's cool. But 1 Mhz, even the dogs in my neighborhood can't hear up there and I'll be lucky if I can hear 15 kilohertz. But thanks very much for anaysis. I still don't understand the original claim by djk that loading down the input of an amplifier magically cancels the effect of cable capacitance. I do understand of course that measuring or listening to an amp that has its input unterminated is noisier than an amp whose input is shorted to ground through 2.2k. babadono

Dr Who?/djk I'm getting confused. The lower input resistance is still getting even lower at higher frequencies because of the capacitve reactance (of the cable) isn't it? Maybe that is what you mean by a non elegant solution. This sounds like hocus pocus to me. What's the difference if the 2.2 k is at the output of the driving circuit or the input of the receiving circuit? It still attenuates the signal because of the non zero output impedance of the driving circuit.

djk, When you say terminate what do you mean? 2.2K right across the input signal to ground? Or in series with the signal? babadono

Coytee, BTW what subs are you getting to go with those jubs? babadono

Coytee, Only 2 feet! Just about any wire configuration should work. It sounds like you have confirmed that you are talking about unbalanced equipment (I own a 3BX also, I know it is unbalanced). The chassis of the 2 pieces of equipment must be tied togrther some how. Otherwise there is no circuit. But at a length of 2 feet it is not going to matter if is the shield or the white conductors or both that are connecting the chassis together. BTW if your 3BX is as old as mine, which it probably is since they only made them for a few years long ago, make sure you give those RCA jacks a good cleaning.[] babadono

Coytee, What are you wiring? Unbalanced equipment? If so you should always use the shield for the ground connection, otherwise why call it a shield? Whether you also use the white conductors is a try it both ways and see. Adding the white conductors will lower the resistance of the ground connection (good) but also increase the capacitance the signal on the blue conductors see to ground (bad).How long are the wire runs? Remember both resistance and capacitance go up the longer the wire runs. babadono

Maybe he is so blown away he can't respond[] W.C. we are all waitng with baited breath. Seriously, we hope nothing bad has happened. babadono

Are we talking about bi amping (active crossover before seperate amps) or bi wiring (seperate wires from same amp to different drivers in speaker)? babadono

Murphy was an optimist[]

Dave, Thanks for jumping in on this topic. Looks like the mini DSP could/would do everything necessary for the Jub 2 way and at a reasonable cost. I have looked at these guys website before, now I will revisit more intently. Eric

Hi All, Thanks for all the responses but I have to go with the opinion of miketn since he owns both and has used both. In my situation a new DC 1 has a much higher WAF then a used DX 38. I also think but of course cannot prove that the algorithms from one EV product to another cannot be all that much different. From an EV to an Ashly or DBX yes but EV to EV? Probably the same engineer or team is responsible for both, ah but I am speculating so I think I will shut up now. babadono

Hi All, I asked this question in another thread and never got an answer or opinion so I am starting this thread. To go to a Jubilee set up 2 way an active crossover and bi amplification is recommended. Since the EV DX 38 is a goner (no longer produced) does the EV DC1 do all that is required? Any other makes/models that have the requiered number of filters? babadono Yes, Richard I am still thinking about coming over to the dark side.

heli001, Will your friend in Burbank be wanting to get rid (sell) the TADs? babadono

Michael, Bob Crites has a tutorial on his website on the rebuild of an AA crossover (using the parts he wants to sell you, of course ). But methinks all his instructions and points should translate into what you are doing. IMHO always SOLDER --- if done correctly it lasts forever. babadono

Dandoyen, I sent you a PM. babadono

EZ, I am running Dave's Eliptrac (with his adapter down to 1 inch) with the stock K55 driver in my Khorns. The sound is much improved over the stock K400 horn. Don't know if I will ever upgrade to 2 inch driver. babadono

My 2 cents: Your circuit is increasing the output impedance of the DAC so keep the cable length distance from the output of your volume control to the input of your amp as short as possible. The higher the impedance the more high frequency rolloff effect of the capacitance of the cable. And just a silly question: Do the monoblocks have level controls? If so this circuit is superflous. babadono

Coytee, I've had an Imperial Kamado ( ancestor of the Green Egg ) for going on thirty years now. Cooks anything and everything once you get the hang of controlling the temp. There ain't nothing like a 22 pound bar b q 'd turkey on Thanksgiving. Get one of those charcoal chimney type starters to get your coals ready quickly without starter fluid. babadono

Dave, This looks good and is probably more than most would take the trouble to go through. An RTA with a calibrated microphone would be the way to go instead of a SPL meter although I trust some of those are quite good (and more common). Being meticulous (scientific) about placement of the microphone (i.e. a tripod or microphone stand) when changing from one speaker to another would be in order. Maybe this is off topic but it seems once you have the drivers balanced and an RTA handy the next step is to EQ the entire system from the listening position. Eric

Hi All, OK I'll jump. What's a miniDSP? babadono

railtycoon, I think you will like Dave's horns. I know I sure do. babadono
