Paradigm Owners Thread - Page 727

I agree with you 100%. When I had DF surrounds, I frequently caught myself looking back at them during a movie.

I went from direct to ADP's for the same reason and wouldn't go back. ADP's work much better in smaller rooms where some seating positions are close to the surround speakers. I currently have ADP-590's on the sides and ADP-390's in the back. Eventually I'll upgrade to ADP-590's in the back to match everything up. Works very well as is though.

It is funny, because I went from ADPs to Directs for that exact reason...I want the added punch directs give.

I got Paradigm Sub 15 and MRX 700. I connected through 50 feet Monoprice RCA cable. I set subwoofer to auto off. After turning off my receiver, I can still hear low rumbling sound. I waited for more than 20 minutes.

Does anybody had similar problem?

I contacted Anthem support and they wanted to try buying audioquest or monster subwoofer cable. Do you have any experience it? Need to find if I can buy from Best buy. Appreciate any other brands or any suggestions.

I have an UltraCube 10 that does the same thing. I believe it's normal operation.

I'd suspect something wrong with the amp or the sub. I'm leaning towards the sub as it sounds like something wrong with the circuitry not shutting it down as it should.

Thanks for reply. How many minutes it takes sub 15 to shut off automatically after receiver is turned off?

While I'm not familar with that sub I do have an HSU VTF-1 that I also set to automatic. It takes about 30 seconds for it to shut down (green light turns to red) after I turn off my receiver and I never hear any hum or anything out of it. I forgot to mention that it is connected via single LFE cable at a length of about 20 feet.

Have you tried disconnecting the input and seeing if the sub's amp shuts off any quicker? My thought is to confirm there isn't a signal coming from the interconnect that is keeping the amp from turning off.

Yes. When I try disconnecting cable, it immediately getting turned off. Does it mean sub 15 is fine. right?

Anthem recommended to buy audioquest or monster. I just ordered this cable.

I will try first with this cable before ordering monster or audioquest. It is difficult to get them in 50 feet.

So, after doing some more research I came across some interesting specifications:

ADP-190
Bass / Midrange Drivers - Two 140-mm (5-1/2 in) M-ICP cones,
25-mm (1 in) voice-coils, GRIP chassis

ADP-390
Midrange Drivers - Two 115-mm (4-1/2 in) M-ICP cones,
25-mm (1 in) voice-coils, GRIP chassis


I say interesting because the midrange and bass drivers on both my Monitor 9's and CC-390 are 6-1/2". I understand the ADP-390 has a single 7-1/2" bass driver, but on a whole the size of the ADP-190's midrange drivers match my front speakers better than the ADP-390.
Does this mean I should look at the ADP-190 over the 390 now?

Pretty much. I personally would get myself to 100% certainty by inserting a 'shorting plug' into the sub's RCA input when testing to see how quickly the amp shuts off. A shorting plug is just an RCA with the center pin, and outer ring connected. If you don't have a problem with the shorting plug in place, the problem is definitely upstream from the sub amplifier.



Since you ordered it, try that cable; but be aware that is not the correct type of cable for your application. The cable you link to is a coaxial digital cable/component video cable. You want an analog audio patch cable Preferably a twisted-pair design, or as I prefer, IXOS Gamma geometry cable (like this one). Good luck!

First, I don't think length of cable has much if anything to do with this issue. That stuff Paradigm/Anthem customer service is feeding you is total BS. Buying a $1000 cable or even a $500 cable is not going to solve anything. A correct Monoprice cable is just fine.
I still think it's something with the sub or the amp. In fact, judging by what customer service told you, I'm almost convinced it's the sub or amp itself (still leaning towards the sub, probably it's built in amp) and they are just trying to avoid having to service it.

I've had the Sub 15 for almost two years and the auto on/off function works perfectly. It takes 30 minutes of the sub receiving no signal for it to shut off, this is the normal operation for this sub.

Really? That's odd. I wonder why such a long time? Anyway, the person who is asking about this also mentioned that he is getting a loud hum as well, if I recall correctly. Is the hum normal as well?

Hi, new to forum. I have an Onkyo TXNR3007 with Paradigm 100v5/cc590 setup. No subwoofer as yet but think about HSU ULS15. What are the best settings for the 100's. Audyssey doesn't run to completion, so I have to manually setup. It fails on 2nd stage, can't find the right speaker.

Does it means power is consumed for 30 more minutes and all Sub's circuitry is still functioning unnecessarily?

The link says "it is subwoofer cable" also. I will test it. Otherwise, I will try the cable you mentioned. I need to check if they have in 25 feet long.

Looking past your cynicism…
It is (very) basic troubleshooting to prove if the problem is in the sub. I may have missed some of the details, but he seemed to imply the sub worked as he expected when he disconnected the input.
Now, let’s get a new “correct” (i.e., not coaxial-digital) cable and try it out. True the cable doesn’t have to be $500, but we are talking about a $3000 subwoofer. A $9.42 cable sure feels like a disproportionally cheap cable to me! How about a nice $100-150 cable? Geez.
BTW… There is definitely a (what you may find surprisingly short) limit on the maximum length of the common RCA interconnect. That is why Paradigm Reference Series and Signature Series subwoofers also have balanced input capability.

I would assume at that point it would just be consuming idle power, I don't think it's really anything to worry about. If your that concerned about it you can always unplug it.

Mine does not hum.

You'll get a little more bass out of the ADP-390's with the LFE at 70 Hz compared to 80 Hz for the 190's and the 390's can handle more power too. I went for the ADP-390's first for those reasons. But recently I upgraded the fronts and center to Studios so I'm upgrading the surrounds as well.

Personally, I'd go with the ADP-390's.

I find the ADP's have plenty of punch, they just don't make it so obvious as to where it's coming from. When I was using directs I could tell exactly where the speakers were. Now I only notice the surround sounds, not the speakers.

You might pick the 190s because of their lower price, and/or smaller size; but performance is definitely better with the 390s.

I know performance is better in terms of lower bass due to the included 7-1/2" woofer on the ADP-390.....but technically speaker don't the 5-1/2" midranges on the ADP-190 match better with my speakers since they are closer in size than the ADP-390's midranges?

First, my position is that the comparison you present is flawed. We aren't just listening to the mid/tweet in the 390. You need to compare the 190 as a product, against the 390 as a product. The 390 is much more capable.
What is the concern/obsession over matching midrange sizes anyway? Paradigm voices their products extremely well; so it isn't like the sonic signature is going to vary between the different models. The 390 just gives you more!
If your that concerned about a seamless match between channels, I would consider direct radiating speakers anyway...

That's odd that audyssey is failing in the second stage. Have you confirmed your hookups?
HSU subs go with anything.

Price of cable has nothing to do with construction or material...well unless it's pure gold wire or something, but then that wouldn't be a very good conductor. At the end of the day it's all in whatever the person wants to spend and it's entirely up to them. I just like to suggest ways to save money, take it or leave it type of thing.
I spent all of $48 on my speaker cables I made myself for my Studio 100 v5s and they are the same ones I would have otherwise paid $1k for. But that's a whole other subject and not pertinent to the case.

Yes, I know about max lengths of cables (speaker, IC etc), but what I was not seeing or maybe missing is what that would have to do with the sub not shutting down and making noise. Would length effect that dramatically? In other words, would it cause long delays in shutting down?

My room is 21 feet long. The receiver is placed on the back and I placed subwoofer at the front since it is recommended. I need at least 30 or 35 feet cable. I can only find at most 26 feet. Here is the link.

http://www.accessories4less.com/make...-26.5ft/1.html

I don't mind spending $100 to $150 for 35 feet cable. I am not able to find. I went to Best buy and they have 15 feet audioquest for $99. Whoever has home theater needs long wires. I am surprised the wires are available in short length.

There is one more input balanced xlr. Do you think I can use it? I don't know if my receiver Anthem mrx 700 supports it.

I was merely bringing up the difference I saw in the two speakers. From studying the specs, the price difference between the ADP-190 and ADP-390 is merely because of the addition of a single 7.5" woofer (while also losing 1" on the midranges).
My assertion was if it is worth paying more for this single woofer addition over the ADP-190, considering they are surround speakers, thereby making the extra 10Hz of lower end bass somewhat....unneeded.
I understand that the ADP-390 "gives you more"....but it's a single woofer, for which you are only gaining 10Hz. Sensitivity doesn't change. Max power changes, but obviously due to the addition of a large woofer in the speaker.
Again, just my observations/opinion.


I do have a more thoughtful observation which can be discussed without turning into an argument:
Doesn't the addition of a woofer (no matter it's size) that fires directly out into the center of the room negate the spatial effects of a dipole speaker. I am referring to, of course, the ADP-390 and it's 7.5" woofer that is positioned to fire directly into the room (since it is on the front of the speaker). Doesn't having the woofer in this position in effect create the sense of a direct radiating sound, thereby calling attention to the speaker?
