Hi Folks,
I'm a Hi-Fi newby looking for some tips... here goes.
Current setup: NAD L75 AV Receiver, Aaron Octagon(Australian made) Floorstanders, 2x Energy Connoiseur XL bookshelf as rears, no centre.
I'm really very pleased with the sound quality of this setup as the Aaron Octagons are very revealling with a great mid-range and with the L75 in stereo mode create an amazing soundstage, from CD, DVD and FM sources. So don't want to change this too much.
What I have available from my first Home Theater setup is a Yamaha RX-V2200 AV Receiver with Mirage FRX-9 floorstanders (these have a built in 100Watt MOSFET 8" subwoofer each). This is a great HT setup, but now I have come to really appreciate the real musical soundstaging, depth, detail and clarity of the L75/Aaron combo.
What the L75/Aaron lacks though is a subwoofer. The Octagons have really good base down to 30Hz and are great with music, but with movies they are missing the deep thump; the really strong feature of the V2200/FRX-9 combo.
The easy option is to go out and buy a subbie, but here in Australia, good subbies are rather expensive, typically twice the dollar value of the same product in the US.
So I was thinking, how can I incorporate the subwoofer portion of the FRx-9's into the L75 setup.
The FRX-9 can be bi-wired/bi-amped and has a bridge that can be removed to separate the sub portion from the woofer and tweeter portions of the speaker. So I was thinking of using just the 8" subbie that's built into these.
I tried connecting an FRX-9 in parallel to the Octagons and the L75 went into PROTECT mode; won't be doing that again. 2x 8Ohm in parallel equals 4Ohm, which the L75 does not like.
I tried running an RCA Y cable from the L75's Sub output jack to the left/right terminals on the FRX-9, but didn't get any response from the FRX-9. I don't think the L75's sub out supplies enough current to run a normal speaker. Any ideas around this? Is there some other way to do this? Idealy I'd like to have at least one FRX-9, if not both running off the L75's subwoofer output jack.
I could try to connect the FRX-9 in series to the Octagon, but that would increase the speaker resistance from 8 to 16 Ohm. So the L75 will need to run harder/hotter to get the same SPL? The L75 is 45 Watts when running in 5.1, 60 Watts is Stereo.
I could connect the Octagon and FRX-9 via a Speaker Switch Box and select the appropriate speaker(s) for music or HT. This allows quick n easy swapping between the two sets of speakers.
Also, the L75 has a digital out. Can I use this to have the L75 as a pre-amp to connect to the V2200 and then have the Octagons on the A-Speakers and the FRX-9s on the B-speakers?
My concern here is that the V2200 is not a very musical receiver, very edgy, overly warm, so I don't want to degrade the current sound quality. Though the V2200 has a Processor Direct setting, so that all the gadgety DSPs don't alter the sound. Will this allow the V2200 to act as a clean amp or will the V2200 still "colour" the output?
Any ideas/suggestions will be graciously received.
Thanks so much! :biggrin5:
