Hi,
If this should be posted in another area please feel free to do so. Or post everywhere. I am not getting any help on audiogon's home theatre area. This might be deep waters... don't know.
I have a Dynaco / Kenleigh QD-2 and would like to know if it is worth setting up ? I am at a couple of sticking points which are really annoying me so the overall worth of the journey would be nice to have in view.
Issues that I am having:
1. subwoofer control. I have a passive subwoofer made by the same designer as my fronts center and rear speakers. the designer knew that I would be using a power amp separately for the subwoofer (even suggested the ampl) . Apparently, the subwoofer miay have been designed in error such as the two drivers wired in series / parallel when they should be the other way - as the subwoofer is laughably loud compared to the fronts which the designer also made for my particular use in this system. The QD=2 seems to have no way of attenuating the subwoofer ? Right now the subwoofer is running with the fronts only. Perhaps hafler matrix systems get louder when in 5 -way setup so the sub would sound normal then ? Again, right now it is LOUD. The fronts are 4-ohm. I have no information about the subwoofer impedance or sensitivity. The fronts are rated at 94 ohm but I do not know if specs from the manufacturer are letitimate. ... so the subwoofer integration is problem one. I was told by some folks to buy an attenuator to put inline. I also have a good Onkyo receiver tha I could use as the subwoofer amp and gain a volume control in the deal. Your input on those 2 choices ?
2. If the front speakers are run directly from the amp, bypassing the QD-2, will the center channel have the information that it needs to the do the mojo of ambient or out of phase information manipulation? The mnufacturer seems to put this arrangement as the peon of setups, but I am wondering about this. (Perhaps referring to the Kenleigh audio website www.kenleighaudio.com then "enter here" > "electronics" > "surround sound processors > QD-2 connection / manual might help) It is spartan...
3. my QD-2 is not the original model by Dynaco but apparently a modded version made by kenleigh audio. Please refer to www.kenleighaudio.com then "enter here" > "electronics" > "surround sound processors" You will see that the center and subwoofer outputs been changed on the back panel. I do not think anything else is different from the Dynaco QD-2 except several hundreds of dollars of price were added : ) The manufacturer, Kenleigh audio, told me that there are 3db of separation between the right and left speakers in the design. That might be an upgrade or mod from the original Dynaco ?
3b. The subwoofer and center outputs on this unit are no longer binding posts but RCA. I have no idea why the manufacturer would do this knowing that I have a passive center built by him and a passive subwoofer built by him. Any way to hiook this up ? The rear panel diagram at the website might be helpful.
4. My rears are in a kit form. I have the drivers, the cabinets and a big capacitor. I have no idea where to go from here to get the rears finishes. The original designer has passed away. I am stuck. If anyone knows how I can figure out how to turn the kit into a finished product that would be great. I was told by Kenleigh audio that the rears in a Hafler matrix have a particular sound signature when done right, not flat. If I remember correctly, they are supposed to tilt up in the upper mids then fall sharply in the treble. I could not find documentation for this so far on the website.
- I would be happy to post what drivers I have for the rears and the capacitor value if helpful. I was told by a guy who has a similar system that the capacitor is inline with two of the drivers in parallel, I think. A VERY simple crossover if that is al there is to it.
Thanks
Ray
