Dunno what happened really, was showing off the SACD of Dark Side of the Moon, and it went, or at least I think it's the twee. Sounds bad though. Have an email into Def Tech now, this will let me know what kinda company they are. Speaker is 2 years old.

Did some more listening when I got home, its the 5.25" woofer... Dead.

Going on 20 hours and no word from Def Tech.

Wow, I'm sorry to hear (read) this, elwaylite. If you start looking to upgrade, be advised that I have cranked my Def Tech Mythos' to truly frightening levels and they've never given me a hint of trouble.

Yours,

David

Yeah, Im a little shocked. Maybe it was a flaw in the way it was built, just there from the get go. They've been pushed hard the last 2 years, but I've built enough car stereo to understand distortion and when too much is too much. I was running about -11 db, and blu-rays are generally -9 to -10, so it was not anything crazy. I'm gonna get this puppy fixed and upgrade the center.

I also wonder if it has anything to do with the Audyssey 80hz setting. The first year I had the speakers I had them on 100hz, and the sub at 120, per Def Tech. When I got down here, and re-ran Audyssey, it of course puts the center and fronts at 80. IMO, 80hz is too low, but maybe not. I'm gonna install the 2000 center, and set em all on 100hz, as Def Tech recommended.

All my Mythos' are at 100hz for the crossover. Actually, I think Audyssey initially set them to 120hz and the center to something like 150hz, but I lowered them all to 100hz in order to get rid of some nasty popping in the sub. Anything below 100 is pushing it IMO.

I agree. A lot of times it sets on room acoustics, which can be bad. I'm wondering if I wasn't just pushing them, or have pushed them too much the last year at 80hz.

Bummer to hear man. I hope Def Tech has good customer support and that you can get it replaced as soon as possible.

**gadgtfreek** · 12-20-2010, 09:00 PM

I'll def keep you guys in the loop.

Cool man. Curious as to how their customer support is. Im considering Def Tech speakers at the moment but Im gonna buy an Emotiva XPA-5 first to run the new speakers i get.

**gadgtfreek** · 12-21-2010, 02:36 PM

Got an email back this AM. Looks like I can:

Send it back in thru the retailer
Send it in directly to Def Tech
Replace the woofer myself with a part from them

Waiting to hear back for clarification.

**bravestime** · 12-21-2010, 04:25 PM

At least that's good news. I assume you will only pay for shipping to the company?

**gadgtfreek** · 12-21-2010, 04:38 PM

Hey Braves, just got an update email back. Since the midrange replacement is pretty easy, they are going to ship me out a 5.25 woofer today. I gotta say, impressed so far.

Glad to hear they are on top of it. Sounds even better, no money out of the wallet. Good Luck.

**gadgtfreek** · 12-21-2010, 05:02 PM

Will be fun, get to see the inside of my speaker

**KuroHD** · 12-22-2010, 10:48 PM

Awesome news man!

**gadgtfreek** · 12-28-2010, 06:55 PM

Service is still going well, 5.25" arrived today. Here is some AV porn for those who like it, and I think the little speaker is built well. 2.75 pounds and a nice basket

NICE!! - can't believe that material pulled away. Strange.

**gadgtfreek** · 12-30-2010, 02:37 PM

Me either. To touch on the Audyssey subject, after I got everything back up today, I turned ALL Audyssey features off, including the EQ, and setup the Xover and Distance as measured (the Denon measures the distance spot on, so no changes there). I then broke out the Radio Shack Analog SPL Meter and checked speaker trim levels from my seating location. Ive ALWAYS thought Audyssey (Onkyo and Denon) set the center too low, and this is over 3 different centers. I found the same here with the meter.

Basically, put the gain at 50% on the sub, and ran the auto setup, then cut all Audyssey stuff off.I made sure the fronts were small and 100hz, per the guy at Def Tech (all surround sound below 100 goes to the sub;Audyssey set them at 80). I then made sure the center was small and 60 hz, per Def Tech (all center sound below 60 goes to sub; Audyssey set it to 60). I then checked the trim levels with the meter, and adjusted them a few db's, to get 75db's at the center viewing position. The fronts had to be adjusted down by 5 db's in the trim level menu, while the center was 3, so the center was def below were the fronts were set. I did not worry about the sub, because Ive always liked where the Denon set it's trim level at 50% gain, because the bass has always felt right.

I watched some DD 5.1 stuff and HD audio stuff, and it sounds damn good. It'll take some testing, but Im now wondering if Audyssey is more than a quick setup for ease. Some guys swear by it, others say the manual way works better. Dunno, but it sounds great now, and the center has more presence. I've always used Audyssey (3+) years, so this will be interesting. Ive talked to some calibrators who also do audio, and they do the same manual measurements and spl readings, so I dunno if you miss the Audyssey eq filters or not.

Regardless, DD 5.1 will be where it should, without the Audyssey issue on this model molesting it.
