Jag Posted July 31, 2002 Posted July 31, 2002 I run the bipole in parallel to my direct rad for each surround side. So the bipoles are above me for that enveloping sound, but that cannot give me pin-point accuracy when jets fly from front to back left. That would give really muddy surrounds. So I supplement with direct rad situated at 45 degree back for each side. This then gives me pin-point accuracy when the jets fly to left back. But of course, no enveloping surround. Add them up and u get best of both worlds.

Add them up and u get best of both worlds. My concern is the load for the amplifier when running speakers in parallel. The current drawn for the amp increases as the load increase. Wonder if my yammy 800 would do when played loud. You're using the Yammy 2200 rite? Do you play them loud?
Jag Posted July 31, 2002 Posted July 31, 2002 I play at about -40db for easy listening, -33db for movies and -50 when its late at night. For that special movie, -25db and rock/trance at -20db. Anyway, since the RX-Vx95 series, yammys have been tested and spec-ed for 2ohm load. But my impedance load is about 4 ohms (2 x 8ohms paralleled). So far, I've not had a cause for concern. The impedance switch is set for 8 ohms load, so if there is indeed a problem, the amp should have blown by now. That means you are using 8 speakers? 2 front, 1 centre, 2 bipoles, 2 direct rad surround, 1 rear centre? Actually 2 rear centres. I know I'm trashing my yammy, but it says alot for its reliability and design! I wouldn't try that for Denons or Onkyos given their heat problems I read on the net previously or unless they have a 2ohm spec.
chucks Posted July 31, 2002 Posted July 31, 2002 newbie qn: wat do u mean by running in parallel? one reply seems to suggest running spks in parallel while another seems to be talking abt placing the bipoles parallel to each other? Miscommunication? Also, wat is direct rad and/or how is it achieved? thanks.

Miscommunication? Also, wat is direct rad and/or how is it achieved? thanks. Slight miscomm here. Running parallel means running two sets of speakers from a single channel out of the amplifier. In Jags case, he is running his bipole and direct rad from a each channel rear. If both of his speaker is 8 ohms, this would effectively duble his load to 4 ohms, which can be very taxing on the amp. As demostrated by Jag, the Yammy has the juice to take it...
Lancelot Posted July 31, 2002 Posted July 31, 2002 Direct rad means direct radiating, e.g, front speakers that you are using are direct radiating, i.e the sound is directly firing towards you. Regarding how it is achieved, you have been experiencing it all the while. When the speaker is facing you and firing the sound towards you, it's direct rad.
Jag Posted August 1, 2002 Posted August 1, 2002 Bipoles spkrs = speakers with speaker cones pointing in 2 different direction. Both spkr cones move in-phase with each other Dipoles spkrs = similar to bipole but one of the spkr cone wired opposite, thus one spkr cone out-of phase to the other. Direct radiating spkrs = Monopoles = spkr cones point in the same direction, projecting sound in one direction only. Pretty much the conventional spkr.
Phil1624705739 Posted August 1, 2002 Posted August 1, 2002 Heavy man... how do u connect ya speakers in parallel.. 1 set in banana & another in spade?? Phil
Jag Posted August 1, 2002 Posted August 1, 2002 Screw onto avamp then parallel using banana plug. Dun like spade coz "dirty" the signal path. Besides, they cost money for practically no increase in performance. Onli look nice.

I'm using spade for my stereo setup, and I find them offering more surface area contact than banana plug.
Jag Posted August 1, 2002 Posted August 1, 2002 Oh no, given between spade, banana and raw, I'd go for 1)Raw 2)Spade 3)Banana But the problem is not the surface contact area, but the quality of solder/joint. Silver solder joints are good. Normal solder joint can impede signal flow. V. important esp for video connc. Look out for shiny and clean solder joints. Anything else is a poor joint. Best are cold weld joints or crimped. Next closest are screw-in pressure joints. These 2 are quite good.

Dun tell me u use another set of binding posts 4 ya bananas?? Phil

Onli look nice. hi, have u try to connect them in serial other then parallel...its can reduce the load of u yummy amp and also allow u to connect the spk cable direct from ur amp... i know the Wattage is going to reduce by 1/2,but i gress ur two pair of rear spk after cobim perhap end up dont need so maney wattage to adchieve the same SPL.. might get worse or might get better....who know right? :)

Didn't want to damage a perfectly good amp. But I read that series connections can affect the sound quality as the first speaker cone movement can induce a secondary EMF which will alter the original signal. Thus the second spkr will produce a slightly altered signal in contrast to the original. This interaction can degrade the sound; by how much i dunno coz i never tried. So I ran them parallel, since the yammy spec their AV amps to 2ohm load. Besides, now no motivation to series them now. Anyway, my SL, SR & SB each all have 2 spkrs in parallel, so if the amp is weak, it should have exploded long time ago.
Ender1624705735 Posted August 1, 2002 Posted August 1, 2002 Wah, so many speakers around. Must be kinda of difficault to arrange them. I also trust the yammy to be able to handle the load. My HT has always been yammy from the DSP 595a, 995 and now the 800.
