@MrGrey

In addition to my question above where is your sub located? Up front next to your mains? If so, you should not be getting localization. I have both of my FV's next to my towers using a crossover of 100hz and I cannot tell where the bass is coming from.

Receiver - Denon 4311CI
Speakers - Klipsch RF-82 II's, RC-62 II, RB-61 II's

with the LINE-IN i can go all the way up to 120hz without any localization but with the LFE i can tell easily. if you recommend 80hz ill keep it that way.

Yes right next to my mains, the funny thing is that only with LFE-IN i can localize it but not with LINE-IN, with LINE-IN i can go all the way up to 120hz easy.

If line-in sounds better then stick with that and an 80hz crossover. Run through some material and make sure you are not getting any localization. I wonder if this is something wonky with your receiver when you use lfe-in?

I was trying different crossover frequencies last night. With LFE I start to localize the bass at 100Hz, and that's with 2 of the best music subs located at the center of the front and back walls, so if you drew a line between them it would go right through me. I ended up sticking with 80.

I haven't tried line in.

i am running The Dark Knight Blu ray right now and its insane allot better than lfe in with no localization. idk maybe but after all it is a $200 Sony STR-DH550 so how much can you expect from it?. i will wait for the onkyo TX-NR747 that receiver looks like a great buy that will last for a very very long time.

MrGrey, the fact that line in sounds a whole lot better tells me your Sony Avr set sub distance/phase wrong when you use LFE in. Theoretically, line in is a bit cleaner but not from what you are describing. If you don't crossover more than 80 or 90hz, I would keep it as is especially if is sounds like 'heaven'
The reason it was more localized with LFE v.s line in when you had the 120hz xover was with line in, your FV rolls off at ~90hz which is why you can't tell where the bass was from (you were missing bass range between 90-120hz). With LFE in, the FV rolls off ~200hz and if your Avr does not filter it out at that frequency, your sub was playing up to 200hz, definitely localized. Most Avr has an LFE bass setting default to 120hz. Not sure how Sony does it.

I use the rubber feet on carpet so the sub will not move at all. I have bulldogs that like to play and when I had the VTF15's just sitting on the carpet I would walk into the room and one would be aiming at an angle lol.

I have found no difference between LFE and Line In in my setup. I just use LFE and cross all my speakers at 80hz in the preamp.

my Sony avr doesn't even have a LFE setting to mess with. i honestly dont see a reason to crossover more than 80hz and if i am getting great sound/ proper sound then ill keep it. it may be the receiver but there is no way of knowing, i could mess with the sub distance in my avr to see if it comes close but i have no faith in it. and if i will be keeping the LINE-IN then i will recalibrate my avr to make sure its doing its best.

You have nice speakers and a great sub. Next on your list of upgrades should be a new receiver.

Yeah, get into an entry level or better Denon and I think you will like the control of settings and audyssey results.

Bang for your buck refurbished stuff from accessories for less is a great deal. You can usually find a model with XT32 for excellent pricing.

Then we don't know what frequency range your Sony outputs up to. Perhaps, it is mentioned in the owner manual? If you can post your sub graph between LFE in and line in, we can definitely tell why there's such a big difference. I suspect your FV was playing up to 200hz with LFE in which explains why it sounds bad and VERY localized.

I bought my Denon off of here about a year ago for around $700. Don't be afraid to go used, but do your due diligence and research before buying used or refurbished gear.

^^ then your LFE and line in discrepancy will go away one you replace your Sony. Everyone I knows here can't tell the difference between line in and LFE in if xovered at 80hz especially for movie.

Thank you. problem solved it would be nice if sony could issue a firmware update since its such a massive issue, it makes using a subwoofer with such an input kinda useless might as well be without.

I agree with tvuong. The only significant difference for you is a bit more delay/phase shift using line in. My guess is your Sony is not handling the delay properly and that is why such a large difference. In any event, if you like line in, stick with it and move on, no problem using it.

That's your sub trim level. Yes, that is safe and what you are essentially doing by moving that value to 0 is running your sub 6db hot. I have mine boosted 6db, so nothing wrong with that.

wow i have learned allot in the last 24 hours from you guys. i never knew that doing this is essentially running hot by 6db i thought it was just zeroing leaving it untouched.

Ive found consistently I have to boost about 5db, after XT32 they tend to report about 69 or 70db's.

Recently took delivery of a F25 =)

Been lurking around AVS Forum for 10+ years on and off.

Decided to replace my 20 yr old Velodyne F1500 and picked up a F25 a couple weeks ago.

Awesome. Going to spread out my posts a bit so I can attach images.

Awesome. I just replaced a Velodyne VX-10 with 2 Rythmik F12s. It was actually the sub I got for my computer a while back and never got around to getting anything more powerful due to the apartment I was in. But that's all history, and now the fun begins.
