For the NAD 326BEE what would be the best way to integrate a subwoofer? I am considering to buy a single powered sub for my purposes.

the simplest would be an RCA Y-splitter at the preout, 1 to sub & 1 back to amp in. but an active crossover between preout and amp in would be the best. bale preout to XO, then mid/high out back to amp in. tapos XO low to sub. there might be pictures sa web that shows this.

EDIT: i just saw a picture of the c326bee rear showing 2 sub outs. same sa yo? if yes you can use either or both to feed your sub.

The suggestion by Markcrenz is correct and effective. And as far as I know using a Y-splitter gives a deeper bass sound. I met a Yamaha salesman and he demonstrated that the Y splitter gives better bass. And also another way may be to use the SUB 1 SUB 2 out to an active subwoofer at the back panel of the NAD. I have this amp but never bothered to connect a subwoofer as the 2 front speaker already gives out adequate bass without a sub. This is up to one's personal preference though.

Thanks so I can use both subouts for one powered subwoofer? If I have two subwoofers one LFE each?

If the sub has two RCA inputs.

these figures give you an idea of how big the power traffo of this amp was and what was the relationship between loaded and unloaded rail voltages......

the narrower the difference between these 2 sets of data, the bigger the power traffo used was....

a fully regulated power supply will have 0db headroom as far as power goes....

a 2ohm continuous rating tells you the amp is really robust.....

so when comparing amps, you can bear this in mind.....

Cause for my concern coz the NAD hooked up with PSB6 gives me reasonable bass just wanted some assurance sq won`t be compromised with a sub.

Yep subwoofers enhances the sound quality in integrated amps. It may be advisable to have the subwoofer "blend in" with your main front speakers. Just have the right amount of bass and not too much. There was a time when I was listening to my friend's amp with a subwoofer. The settings of the sub was too dominating that listening to the music for many hours became "painful to the chest" and tiring.

Imho noticeable difference nila, pero mas magkalapit sila than C375 vs. C356.

i really wanted to get the 375 kasi but i ended up with the rotel a1520 due to money constraints. but the 1520 sounds really, really good. I wonder how it compares to the 375.

If you're happy with the RA-1520, then there is no need to worry.

The sonic signatures are very different so it's hard to compare. The gaps in terms of output capacity and SNR are also quite sizeable. The RC-1580 + RB-1552 may be a closer competitor for the C375BEE, performance-wise.

armymanhaha · « **Reply #102 on:** Apr 10, 2012 at 08:08 AM »

sayang, konting dagdag nalang pala naka 375 na sana ko. 4ohms kasi 'tong speaks ko eh kaya i always felt that it needs more than 100w to drive it properly (Audience 42). Although I'm thinking of getting an easier-to-drive set of speakers too.

Where can I audition a 375 ba? Nangangati ako ah..

The RA-1520 should drive an Audience pair without a problem.

You can contact Watt HiFi, Audible Illusions, Spectra or HiFi Plus to demo the C375BEE.

But what happens when I use the 2 sub outputs on the NAD 326BEE? Can I just connect a pair of subs powered by an external amp using the Y configuration and just ride the output without a crossover? Hope someone can educate me on this TIA

markcrenz · « **Reply #105 on:** Apr 10, 2012 at 09:02 PM »

afaik dumaan na sa mixer/crossover yung mono sub out. di mo na kailangan ng external crossover. just connect sub out to sub amp in. a single rca cord would be enough if you're using a mono amp.

Doesn't your subwoofer have an onboard crossover?

Granting I don't use a crossover just 2 subs which are powered by an external stereo amp? will the Nad take care of the frequency distribution?

Afaik, the C326BEE has full-range sub outs. The sub outs in this model are merely mono pre-outs (I think).

JojoD818 · « **Reply #109 on:** Apr 10, 2012 at 10:41 PM »

If they're called sub outs then there should be a crossover to take care of the higher frequencies, but if it's called a pre out then it has got to be a full range signal.

I am inclined this is so but I don't have the means of finding out yet

. Hope somebody with a 326 BEE who has tried it can share the experience.

interesting master. haven't auditioned the c375 though, i thought there is going to be a difference in sonic characteristics seeing the heft of the 375's guts are massive compared to the c356.

easy way to find out:
1. set volume to minimum and turn off nad.
2. disconnect preout/amp in connection.
3. connect sub out to amp in.
4. turn nad on.
5. set bass to minimum.
6. play something. no, not your guitar!

7. slowly increase the volume and listen to the sound. at this point it would be easy to determine if the sub out is filtered or not.

JojoD818 · « **Reply #114 on:** Apr 11, 2012 at 09:53 AM »

yep, easiest way to find out is to check it.

I agree. I just based my statement from the sub outs of current HK and Onkyo 2ch gear which are full-range mono pre-outs. What I said was purely an assumption, since NAD didn't indicate any cutoff / bass management info in their product literature.

dvdspike · « **Reply #116 on:** Apr 12, 2012 at 03:57 PM »

The manual just states for connection to powered passive subwoofers?

I have the 326bee sir Matt. It has the subwoofer preout at the back where you can use your subs. My subs has a crossover adjustment so that's what I use to filter the frequency coming into my sub. But I prefer no subs in my music. I saw that you are upgrading to a floorstander. I'm using the same, now what I do is just adjust the bass knob on the nad.

Yup subs are for queers hehe JMHO

Then again I decided for now to keep my PSB 6 it gives me adequate bass for my room. And it sings wonderful really!

I just got a NAD 3100 integrated amp through a swap. The amp makes my Wharfedale Valdus floorstander sing better than my previous amp. The mids and highs are perfect and the lows are loud enough but not boomy. May konti lang problem, yung led light na nakatapat sa soft clipping ay permanently lit! Is it normal? Di ba magli-lit lang sya kung may soft clippings just to give signal? Merong switch on or off sa likod para sa soft clipping, pag naka-off sya, di ba disable yung function?
