May be you have a smaller room.

That could be and I only thought that after I posted. One thing I forgot was to ask the room dimensions and how the speakers are palced in teh room relative the listening position.

 

[3db]

I beginning to think you have an issue with your Denon. My room is 10' feet wide for a lngth of 12' and then opens up wider to about 25'. My speakers are placed against the back of the 10'wide wall, centere 7' feet aprt and 2' from the back wall. My listening postioning is 7' away. My celiling consisting of drop tile is between 6' and 7' (haven't measured it) and I can get easily into the 90s.

That aside, your approach of cranking your PSBs to get sound into the other room is flawed and hard on your speakers. Get another pair of speakers like a pair of B15 or B25 and mount them to the wall using this..

If thats spouse unfriendly, get some celing or in wall speakers and save your PSBs at all cost.

Sorry about not getting back to you guys sooner, I took the HTIB recevier from the bedroom and tried it with the PSB's, there was a difference I took a reading and it came in at 90dB's @ volume 10 and this was with the same speaker wire that was hooked up to the Denon. So I reset the Denon and nothing changed it's still not delivering the way it should so it looks like the issue is with the Denon.

I can't see how a HTIB receiver has more ability to drive his speakers then his Denon, unless its defective...notwithstanding the room.

I agree and thats why I think the Denon is either defective or is configured to.........


wait a sec.. Ares....

What do you have the impedance selector switch set to? Leave it at 8 ohms, not 6 or 4 ohms.

 

[Ares]

I have never switch it, still set @ 8 Ohms. I think we have a misunderstanding here I'm not trying to pump music through the whole house just loud enough for me to hear it in the kitchen which is right next to the HT room where I am right now typing this which is an additional 7ft away from the listening position to the chair I'm in now without the receiver at +0dB. My wife has used the HTIB to listen to music before and I can hear it from here and my bedroom is on the 2nd floor. It's a sad state of affairs when my HT isn't loud enough to hear one room over and the little HTIB can be heard from the 2nd floor.

You checked the switch? Maybe it was inadvertently bumped into the other position. Maybe you have a faulty Denon... I don't know anymore.

I understood most of what was stated had to look a few things up to make sure I understood the weight of your point, so in essence there is nothing wrong with receiver, it just has limitations correct? So stepping up from a $500 receiver to a $1500-$2000 receiver would offer the improvement I seek correct?

It likely will. However you need to look at the specs clearly. I would never buy any amp or receiver that only quoted its power into an 8 ohm resistive load. If you do you have no clue how it will drive real world speakers. If you want to be certain you need to look for something that gives you 100 to 150 watts into 8 ohms and 200 to 300 watts into four ohms. That way you know you will get the job done.

Hey Ares...have you tried using the Denon in the other set up just to make sure you eliminate all the angles. Fwiw what are the specs on that system since it seems to boiling down to that?

Not necessarily.

You went to a cheaper HTIB receiver and got a SIGNIFICANT increase in volume in the same room with the same everything else.

Just make sure your NAD dealer has a nice 30-day return policy just in case.

Hey, wait a minute. Are you just trying to make excuses to your wife so you can get a new receiver?

 

[AcuDefTechGuy]

I understand completely.

I do the same thing.

I crank up the volume in my HT room and listen to music while I'm cooking in the kitchen or eating in the dinning room or folding clothes in the bedroom.

I think A LOT people do the exact same thing.

I also like to place my hands on the walls in the kitchen, family room, and bedroom just to feel the walls shaking when my BP7000SC is playing in 2.0 Pure Direct.

 

[Ares]

I thought about that but those little speakers are 4 Ohms which might be the last nail in the coffin for the Denon. Here are the specs 70WPC @ 4ohm @1kHz,THD 10%

Hey, wait a minute. Are you just trying to make excuses to your wife so you can get a new receiver?

Shhhhhhhhh.......you type to loud my wife might hear you. It all seriousness at this point my only hope here seems to be an upgrade and the question remains which route to take.

You checked the switch? Maybe it was inadvertently bumped into the other position. Maybe you have a faulty Denon... I don't know anymore.

No I didn't, it's still the same way it was when it left the factory, I have no clue how to change it and I have read through the manual it doesn't state how to do this either.

It likely will. However you need to look at the specs clearly. I would never buy any amp or receiver that only quoted its power into an 8 ohm resistive load.

Thanks TLS I will keep that in mind while I'm shopping around.

What little speakers? If you referred to the T45, they are 6 ohms nominal, 4 ohms minimum with sensitivity of 90 dB 1W at 1m anechoic so they are not that hard to drive. Still, the AVR1910 is not going to get you good performance on those speakers unless the room is really small.

As others have pointed out, if your other HTIB receiver can get you 90 dB SPL at volume position of 10, there is no way the 1910 should get you only 75 dB at position 0. Either the 1910 is defective or you have set something wrong.

Did you check your speaker level settings and make sure they are all set at 0 and not -6 or something? I can't download the manual from the Denon site right now. It was really slow when I tried earlier. I just wonder if there is something in the settings that would mute the output. Do you know how to do a reset to factory default settings and go from there? I am not disagreeing with TLSGuy but I do think a 1910 in good operating condition with the correct or factory default settings should be able to do much better than a mere 75 dB in your room, driving those PSB speakers when the volume is set to '0'.

I was referring to the speakers that came with the HTIB they are 4 ohms nominal. I posted somewhere a page back I think that the Denon was reset to the factory default settings and still was having issues with it. I can't remember what the read out was I think it was either 80dB or 90dB, I would have to do it again to be sure.

Sorry I missed that post. If you were getting 90 dB after a factory reset then it could be normal. Those HTIB speakers most likely could not get you much more than 90 dB unless they are in a small room. You just can't expect to get quality sound at mega SPL from some low cost 4" drivers in their mini enclosures. By the way, I think most of them are 4 ohm speakers. That does not automatically mean you need to push them with a big NAD power amp. In fact, 4 ohms or not they are typically powered by HTIB receivers that weigh less than 20 lbs soak and wet with built in DVD/BD players.

Feed the 1910 with your T45 and play your favorite 2 channel CD, and I guarantee you will get your 90 dB at volume 0 from 7 feet away. That is, after a factory reset.

 

[Ares]

That's what I got with the 1910 and T45's after resetting the Denon, Billy made a suggestion.

Hey Ares...have you tried using the Denon in the other set up just to make sure you eliminate all the angles. Fwiw what are the specs on that system since it seems to boiling down to that?

I would have given it a try but the HTIB speakers @ 4 ohms had me reconsider and the post with the specs and so forth that caused some confusion. I'm just a little disappointed that it take's the receiver to hit 0dB with default settings to even come close to hitting 90dB's.

 

[PENG]

I think I should get some sleep and then re-read all the posts before suggesting anything else.

No worries, I'm glad to hear all ideal's from you guys since my experience is very limited in this field, even if it's repeated it's still good advice thanks Peng.

If you can get the NAD T775HD from your local dealer for only $1,400, then run as fast as you can and buy it STAT because the listed price is $3,000:

or if he really feels his Denon is inadequate he should look into that Yamaha rxv1900 on sale at newegg for $599.00. It would easily drive those speakers and later if still not happy use it in a pre/pro set up.

My 2 cents....Bill

I can vouch for that as I have the RX-V1800 which is identical from an amp/powersupply set-up
