Title: Bi-wiring the DM945's Post by Fireblade on 01/28/12 at 02:42:44 Hi! Has anybody tried to bi-wire (not bi-amp) the DM945's? Any tangible advantages? So far my experience has been with bi-amping non-Decware speakers and amps with good success. I've never tried bi-wiring alone though, so I'm curious whether I should try that configuration when my DM speakers arrive. I always thought bi-wiring per se was not useful, as it just by-passes the binding bridge, which should not make much difference (unless the bridge material/design is not a good conductor.) Any comments will be appreciated. |
Title: Re: Bi-wiring the DM945's Post by Fireblade on 01/29/12 at 18:57:21 In view of the excessive number of replies to this request, let me just quote a study I found which was set to check if there are bi-wiring benefits in general: Conclusions Some speakers may benefit from bi-wiring, particularly those which have a tweeter with a higher impedance than the woofer. Also, IF resonance in cables is audible through some secondary mechanism, biwiring may reduce this by creating an unbalanced transmission-line that will tend to damp the resonance. In order to ascertain that bi-wiring would be beneficial in my case (DM945's), I need to ask this forum what the tweeter (ribbon) and woofer (transducer) independent load impedances are. We know the overall nominal load impedance of the speakers is 4 Ohms. This may be a compounded average of the independent load impedances of tweeter and woofer, with the tweeter's usually being higher than the woofer's. Here's the ref on the study mentioned, which I found very well structured: http://www.empiricalaudio.com/computer-audio/audio-faqs/bi-wiring-speaker-cables Thanks ... |
Title: Re: Bi-wiring the DM945's Post by ZYGI on 01/29/12 at 23:56:58 FB, If you order the 4 ohm version, then yes your woofers impedance would nominally be 4 ohm. The tweeter is a 5 ohm load, which is a resistive impedance in its frequency range. Never tried bi wiring a pair, so i couldn't help you with that. Zygi |
Title: Re: Bi-wiring the DM945's Post by Fireblade on 01/30/12 at 01:25:59 Hi Zigy! When I spoke to Steve he said the DM945's were 4 Ohms. I guess that's the default spec unless you ask for them to be wired at 8 Ohms. Thanks for the information confirming a typical higher load impedance on the tweeters, relative to the woofers. According to this study then, there are benefits in bi-wiring the DM945's. If you're interested in the benefits, check them out in the article I linked in my previous post. My current SS setting is bi-wired by the designer, so I have double cabling and I'm kind of used to it (the setup is bi-amplified, BTW). In any event, I think I'm going to test both arrangements and decide with my ears. Thanks again and take care ... |
