Driver facing backward ???

My 2 channel setup (without bass management) which I cannot move around,prevents me from easily changing the configuration of my subwoofer Sealed F15. For audio, switch is at 50 hz and for HT viewing at 80 hz, I normally for bump up the gain when watching movies.
Right now, its very diffcult to adjust the settings due to space contraints. I was thinking of facing the subwoofer to the backwall. All walls are concrete and floors.

I was wondering if there was any disadvantage to this configuration

I'd be more concerned about the mains in the corner like that than the sub. Other people will chime in, but I think 6" is ok for clearance to the driver, but maybe try a bit more if it looks ok.

Just watched a couple movies and I'm really loving the FV15HP, it seems to disappear until required then delivers in spades. The whole sound is improved because the sub is so tight and doesn't colour the upper frequencies. I won;t have time to set it up properly until late March (will do a brief review then) but even with only trying a few locations and not gettinginto the PEQ it integrates far far better then the vtf-3mk2 did after hours of trial and error. Without hesitation I can recommend this sub. For the record I'm in a sealed 14'x18'x9' room. I was torn between this or two lesser subs and I'm very happy with this choice.

I run at volume right at around -10 , which is about 70% of volume.

If your getting port chuffing get with Brian and make sure they installed the "port cap' (which I am sure they / he did).

+ The only other reason why you may be getting clipping is your room may big too big for the sub and not pressurizing. I am in a closed in HT room, so my bass is tight and clean.

Good luck.

Worked like a charm! I rocked my system out this weekend for some family that was in town and had no port chufflin. I'm a happy camper!

Hi Brian/Rythmik

I am an owner of F15 which is in my basement with Bowers Wilkins CM9. I have a few questions regarding Audessey settings. I mostly followed Dave's recommendations at Ascend forum.

Once I run the audessey I am chanign the following and want to know if this correct

1. change front LCR to small from large
2. Change the cross over setting for front LCR to 60Hz. Audessy sets this to 40 HZ
3. change the cross over setting for rear speaker ( BW DS3) to 80Hz
4. Bass setting to LFE and not LFE+Main
5. LFE cross over to 80Hz ( I was reading somewhere to leave it at 120Hz)

Also my sub is located 1 feet behind the listener position. But when I see distance in Audessey setting it is set to 4.8 feet or something. The least number I can set it to is ZERO. Is this alright.

I am using LINE IN and not LFE IN as suggested in the quick guide.

Finally do I have manually turn the cross over knob on the sub to around 80 to match it with the setting I changed at step 5?

Thank you very much

1. I think you typed that backwords, LCR + surrounds should be set to small
2. that's fine, you may experiment with 80 to see if you like it better
3. should be fine, what did audyssey suggest? it's ok to raise but not lower
4. yup
5. Change that back to the highest possible setting, prolly 120
6. Distance. Trust in the Audyssey distance measurement unless you have measurement gear to improve upon it. It will commonly be greater than physical distance dues to the delay caused by electronics. (eq, crossovers, processing, and such)
7. Input: You should probably use LFE in since you are using audyssey and your AVR bass management. Line in enables crossover and phase which your AVR is doing for you so the sub doesn't need them active.
8. Crossover on Sub: Set this to as high as possible since the AVR already crossed over, however if you use LFE in it does nothing.

hope this helps

4. Bass setting to LFE and not LFE+Main
Bass setting should be LFE+Main. That means all the bass frequencies from the LFE channel and the main channels are re-directed to the subwoofer.
If the bass setting is set at LFE, the bass from the main channels are also re-directed to the subwoofer if the main speakers size is set to small.
So, both will work fine.

Agreed, so it depends on the mains. I don't want mine doing anything below 80Hz and do not want double bass turned on so I am LFE only.

Another note, after some of these things you may change (Line In vs LFE, crossover on sub) you should rerun audyssey then re-tweak those things audyssey re-set

Are you talking about the foam plug or is the port cap something different?

That was not my understanding of LFE+Main. I thought that this setting was to direct the LFE channel to just the sub ("LFE") or to the sub and the left/right channels ("LFE+Main"). And that this could not be set to "LFE+Main" unless the left and right channels were set to "Large" (not bass-managed). Someone please correct me if I'm wrong.

Please use "briand" and then our company name. It is not a good practice posting email address. It will lead to a bunch of junk emails.

That is something else. Let us just say that is an experiment that we want to see how much more port noise is there if the port is only flared on one end. The answer is quite a bit. All of our ported subs should have flare on both ends of the port.

This is my first time using Audyssey, but I was able to set my front speakers to small and the subwoofer to LFE + main.

Still haven't figured out if I've gone and borked the whole thing, though...
post #8327 of 15139
^^ I think each AVR company has its own terminology. So check the user manual. The key is to set front speakers to small and make sure bass only come from sub. There is another mode that bass will come from front speakers and the sub. That one is problematic because the same frequency is replayed via multiple speakers with dissimilar characteristics in phase and roll-off.
post #8328 of 15139
Well I've definitely borked it; on my Marantz SR5006, I set the speaker size to small, but the speaker config still shows them set to large and the crossover shows the front speakers set to full band. I'm getting very little bass output from the sub, so something's not working right, but the manual really doesn't go into detail on how to alter the Audyssey settings.

I have the younger brother to your AVR, the SR5007. You can change your settings in the AVR's menu. Using the AVR's remote control, hit menu and go into the speaker or audio menu selection and go from there.
post #8330 of 15139
If the 5006 is similar to my 6003 - and from a quick glance at pgs. 94-95 it does appear to be - you run Audyssey, store the calibration, then go into "Speaker Setup" and set:
- all speakers to "small";
- subwoofer to "yes";
- bass setting to "LFE"; and
- crossover to 80Hz (or as desired).

If that's not working, you may have an issue with your AVR.
post #8331 of 15139
I've gone back and changed everything to those settings, but the Speaker Calibration still shows the speakers set as large rather than small, even though I changed them to small manually after. I'm thinking that's just showing the results of Audyssey and not the actual manually-changed specs? I also enabled the dynamic EQ and that made a big difference. I did notice there's two places to change the crossover frequency...I've got one set to 80Hz and one to 120Hz, which seemed to produce the best results, but I'd have to check tomorrow to see where each was. I know the sub crossover is set to 120Hz, and the other is just labeled "Crossover" under speaker settings somewhere, but I can't remember anything more specific at the moment.

I think I may be sitting in a null spot - I don't have a whole lot of room until I can move things around this weekend, so I pretty much plopped everything down where I had the space - and that may be one of the major problems.

Still, the LV12R kept up beautifully with some very aggressive double bass in music, so it's probably just fine-tuning from here.

Sounds like this is the case as I see the same under Parameter Check on my Denon, although all my speakers are set to small. Best to look at Manual Setup or something similar with your AVR to view your actual settings.

Just got my FV15HP today. Haven't had much time to play yet nut I thought I ordered the spiked feet but apparently I didn't because they they weren't included..Anywhere else to get them(link)? I know I could order from Rythmik but just wondered if there are any other options since I see they are a custom size..Thanks.

Both of you are wrong.

Quote from Denon manual:
Quote:
Bass Setting Subwoofer Mode : Select low range signals to be reproduced by subwoofer.
• LFE : The low range signal of the channel set to “Small” speaker size is added to the LFE signal output from the subwoofer.
LFE+Main : The low range signal of all channels is added to the LFE signal output from the subwoofer.
Select “LFE+Main” if you want the bass signals to always be produced from the subwoofer.
post #8339 of 15139
Just saying, if all speakers are set to small, the setting is moot. Having been declared an official incompetent, I feel comfortable with my LPF on mains and center channel being set to 40Hz but at the same time, I'm using LFE+Main as all the speakers are set to small. The point, the definition and use of the two settings is user dependent, on how the user has individually set up internal menu settings as to the definition, for their purpose, being valid or not. Again, just saying.

It is M10 thread. You can still place order and we will ship via priority and you should get them before weekend.
