post #5251 of 5542
Hi,i have been reading on here for a while but never posted before.I finally pulled the trigger on a set of mythos st towers.I have always been a fan of the mythos speakers having owned the mythos four and ones.I was so excited to get these home and hooked up.So I unboxed the first speaker put the base on and put it in place plugged it in looked great and no problems.Took the second one out put the base on put it in place plugged it in and it sounds like wind is blowing thru the speaker:mad:I tried everything and it sounds real bad I was wondering if anyone has had this problem before and what it could be?if I don't plug the speaker in it sounds fine but as soon as I plug it in it sounds like wind and hissing thru the speaker.I did buy them from a authorized dealer online so I hope I am covered but man was I disappointed when that happened.

That's a new and strange problem to me. I would send it back for and exchange.

Been there, done that. First, push in on one of the 4 inch mids--oops--5 in your case--and watch the other one--see if it pushes out while you're pushing its twin in.
This setup is designed to be absolutely airtight--if the other driver is not popping out, while pushing its twin in---it ain't airtight--I guarantee you.
If you don't get a see-saw opposite reaction, it is a problem with the MDF plates seals that make up the isolation chamber cabinet for the mid-tweet-mid upper chamber. Undo the 8 phillips screws that hold the mounting plate for these 3 drivers, and gently remove the plate/driver assembly. Check the skinny litlle foam gasket between that assembly and the alu cabinet. Yes, it is not a very substantial gasket. Now, on to the more likely suspect: The hot-glue seals between the single bottom, and the left and right MDF plates.
Tap on them--they may sound loose. Power up the speaker (with the upper section still removed). You may just instanly hear rattles, air leaks, or some other symptom, indicating a bad seal. A large cartridge of good grade low volatility silicone is your friend here. That hot glue just does not bond well--and the seams may just have broken loose. Hint: H. Depot sells allen-head 4mmx20mm black screws for 56 cents for two. Hint: get the correct metric allen driver--no US sized driver works--unless you are good with a grinder. (:
Now--the woofer/dual passive section of the cabinet can have similar problems--but there is no glue involved. Again--skinny foam gaskets on both passives--and the race-track active woofer itself. Check the gaskets. I have not tried to get gaskets from DT--I made my own for the upper section--but this is not for the timid--it is a very complex pattern. Also--I read somewhere that the RCA Sub input jack can leak, and that tight fitting rubber duckies are available from DT to plug that leak. Lastly--the plastic cap at the very top of the speaker can leak , and I heard, the same can occur at the very bottom--above the granite base. Good luck--keep me posted to let me know if any of this pans out as I say.

Forgot to mention:
I hate to send stuff back. If they couldn't build it right--or fix it correctly on a refurb--it is obviously time to take poor quality control into your own hands--if you have some basic skills.
I love my STS's. The perfect sound, at last---However, while the design is a 12 out of 10, the execution/build quality is about a 7.5, if that. For another 50 cents, they could have used allen head screws of decent quality, instead of the soft-metal phillips--the gaskets need desparate help--and their hot glue is simply crap--given the modern adhesives available. Heck--they put 100K Audies together with epoxy!!
http://www.audiworld.com/news/12/future-energy/
Hope the upper cabinet leak-fix I suggested does the trick for you.
Removing the bass active and passives does not work the same way!!!! If you loosen the dozen phillips screws---surprise--the drivers drop down into the cabinet. Hint: Remove the top-most passive plate--it will come out if you hold your tongue just right. Unscrew the active racetrack woofer. It will not come out, no matter how much you curse it---just slide it towards the top. Now you can loosen the screws holding the lower passive--slide it to where the active was--and yes, it also will now come out.
I will not tell you how to remove the woofer (trade secret)
Never, ever touch the screws in the middle of the passives!
Hint: You can get a hand under the active woofer to hold it in position, while re-assembling the screws. A decent shop vac, or other strong vac, can easily hold the passives up while you get the screws started. Beats pinching the rubber surrounds, trying to hold them up:
Hint: Those funny looking styrofoam "U"-shaped pieces of packaging do a great job holding the speakers with drivers up--while doing repairs with them laying on the floor (carpeted, I hope)

Thank you for the detailed response and your time and effort in trying to help me solve my dilemma. On line purchasing is becoming more of a headache then I expected and I am feeling like I am alone in this to resolve this high $ mess. I will explain what has taken place since my original post in a minute but let me start by telling you that I immediately took your advice and checked to see if it was sealed. I did push on the mids and did get the response you said I should if it was sealed properly. So now let me explain better what has taken place. The one speaker works perfect. The other speaker did arrive with definite damage to the bottom of the box. Physical appearance was fine. When just speaker wires are connected the speaker seems to work fine, but when I plug the power cable in is when all the hissing distortion starts coming from the sub woofer. So I called Def Tech and they seemed to think the amp was blown, so they are sending me out a new amp board to replace myself. The tech at Def Tech seemed to think that with the knowledge I have this replacement should be an easy fix with attention to detail. Do you happen to have any experience with this or helpful hints? When I originally called the seller (who wasn't as cooperative as I had hoped), they tried to tell me that I needed to replace the transformer and they would send it for me to replace. I wasn't to confident that was the problem so I again called Def Tech at which time the tech there told me he had already talked to the seller and told them he disagreed and that they were sending me the amp. The part should be arriving Tuesday and I am hoping my problems will be resolved. I am interested in your opinion now that you know I checked to see if it was a seal issue & found the seal seems to be just fine. Do you agree about the amp? I will keep you posted and if you have any helpful hints it would be greatly appreciated.

Since the problem occurs when plugging it in the amp is the only active part of the speaker. Replacing the amp is where you should start . Hissing and distortion is a sign of a blown amp. Once you replace it you will be fine unless there is another problem in addition to the bad amp.
Good Luck
Chris

I have too agree. The amp may solve your problem. Yes it is easy to replace. Remove the base. Then there are screws holding the bottom assembly attached to the tower. Once loose carfully remove it. The transformer is attached to it and does not have to be separated from it (the bottom). From there you should be OK.

Well just bought a couple XTR-60's to upgrade my XTR-50's and a pair of XTR-20BP to use as front heights. We'll see if I notice much of a difference once its all installed and calibrated...

Very important you check the amp board brackets. There are two issues here to be aware of, and save yourself a lot of grief.
First--there are two different styles of upper amp board brackets. One has a cut-away, likely for the smaller STS--no cut-away for the Larger ST cabinet. Sharpie pen in pic points towards the cut-away.
You never know which bracket will be shipped to you.

Second--the distances between the mounting holes on the ampboard brackets also differ. Best advice--use your old brackets.

Again, amp board (not toroidal transformer) removal through the lower passive opening is fairly straightforward. I cannot comment on doing this through the base (?)

Was in the market for a new Processor. Have a Mythos ST pair up front, 10 center and Gem XL surrounds. No external sub...yet :-) Planning to add a Oppo BDP 105. Currently using a Yamaha RX-V871 as a pre out to a Sunfire TGA 7401. PS3 is my Blu-ray transport. Interested only in a dedicated processor at this point. Anybody with suggestions and/or experiences? Thanks!

Hello Nick, were you able to get the amp issue straightened out? Does everything sound fine now? Best regards, Joe

Might be worth looking into the Sherbourn PT-7030 AV Preamp. Andrew Robinson formerly of Home Theater Review and now of Andrew Robinson Online has adopted it as his new reference AV Preamp, and it is surprisingly affordable given its capabilities. Here is a link to his review: http://www.andrew-robinson-online.com/review-sherbourn-pt-7030-av-preamp/

I have not listened to it personally, but if I were in the market to replace my Anthem AVM30, I would lean strongly toward this model.

Would appreciate your thoughts back as to whether this is what you had in mind. Take care!

Hello, I was wondering where the Mythos 3 ranks as far as centers go?

I have a Pro Center 1000, and I'm looking to upgrade as the PC1000 can't seem to match my BP7006 tower speakers.

Price is a major consideration, but I can't quite figure out where the Mythos 3 ranks in terms of Center channels.

I see that the Mythos 3 and Mythos 7 I can get at great prices due to friends, but I'm not sure if they will cut the mustard as a CLR2002, CLR 2300, CLR 2500, 8040HD, and 8060HD might. I've been waiting and watching all summer, but nothing I saw struck me as fantastic. I may have to wait longer until I was offered some Mythos Centers I had not considered.

If price wasn't a concern, I would simply go with specs and exactly matching timbre, but as it stands, I want a Def Tech center speaker at a great price that comes really close.

Right now, I have friends that want to offload Mythos product and so here we are.

Thanks again for the help Def Tech and Mythos experts.

If your friends have a Mythos 3 for you to try, why not give it a trial and see what you think.

It's a long drive (different city, 3+ hours), and the stuff is boxed up, so before I bother with committing to that drive and unboxing product I wanted to post here and get some answers if there were any answers to be had.

So did you have any information on those center speakers rankings or some intel on the Mythos three vs. clr2000, 2002, hd8040, etc

Sorry, can't help there. I have a Mythos 3 paired with Mythos 4s across the front. I love them in my room, but can't say how the 3 compares withe the others you mention or would blend with your other speakers.

I have the Mythos Eight as a center channel. It was had for only $250. It has larger drivers then the Three and Seven. It really stands out in my system with Fours for fronts and Twos as rears. If I could wall mound the fronts and rears my system would be better with Eights all around.

I would strongly consider the Eight center if you can find one at a good price.
post #5269 of 5542
I will look into the Mythos eight, what a deal you got for $250.
post #5270 of 5542
Hi I would like to thank everyone who helped me and responded to my problems with my mythos st. Sorry it has taken me so long to post how it went. I did the amp change and everything seems to be working fine now it did end up being a little more of a pain then I thought it would be. First the screws on the bottom were very hard to get out they had some kind of thread locker on them, on one I had to drill the head off just to get it out. The other thing I ran into was the glue all over the connectors, that took me a little time to get that off. Why they would do that I don't understand when the connectors snap together anyway. But when I did get all that done and back together I was very happy when I tried it out and all the noise was gone. I do like them very much they sound great.

My only thing now is I have a mythos eight for my center I know the mythos ten is recommended for them and I am just wondering how much difference would it make? is it worth the extra money to get the ten and then sell my eight? Or will it not be enough difference to even bother?

Newegg, but its sold out now. You know the clr2300 is the best match. But I'm not sure why the pc1000 is not working for you. I bet any of the Mythos (8, 3, or 7) will sound similar to the pc1000.

If you really set on a new center, I'd go with your friend's Three. It has larger drivers then the Seven. I'm not sure why Def Tech replaced the Three with the lesser Seven. And since its newer it's more expensive.

If I were you, I'd make the pc1000 work for now and wait for a deal on the clr2300.

Hi guys,

I would love some advice.

I unfortunately rushed into a purchase frown.gif

I just bought a 5.0 setup including Klipsch 2x RF 82 ii, RC -62 ii, and 2x RS 52 ii

I love the sound of klipsch, but these speakers are going to be too big for my space. I am going to see if I can cancel or return the order or maybe sell it as new when they come in if I have to.

When I went to best buy I was blown away by the STS, but unfortunately its out of budget. So I am looking at some older models. But I am confused.

If I want the best slim towers before the STS came out, which ones are those? And which center and surrounds match?

Thanks!

Also as a corollary, how come I can't find Mythos One in black? It seems all of them are silver. I would prefer black. I don't want the projector screen to reflect off them too much.

I just read this, and thank you for the words.

I think waiting for a deal on the CLR2300 (or comparable Def Tech center) is my best bet.

Because the Mythos One's are discontinued and people are very satisfied with them and are not selling.

You're preaching to my choir. I've been looking for black Mythos One's since the beginning of the year. eBay sellers (just two of them) wanted $1400 for a used pair. But Newegg had brand new Mythos Fours for $250ea. Kind of a no brainier. I'm not sure how much better my system would be with the One's but theres nothing I can do about it since the One's cannot be had.

For the record, I'm very satisfied with my current system. But my Eight center, with the same drivers that the One's use, really sounds special and I wonder how much better it could be.

So the 8 would be the matching center for the Mythos One? Not the Three? Or would the ten be better?

My use is 90% home theater so I want a quality center.

And which surrounds would be recommended?

Thanks guys! I am new to def tech and trying to learn.

I had the one's and the reflection is not as bad as you may think. They reflect no more than the black. If you slightly angle them toed in (which you will probably do anyway when tweaking them during setup) it is a non issue.
post #5278 of 5542
Thanks. It seems like a really good option for me.

How would the Ones be with the Ten as a center and either Twos or gem xl for surround?

Or any other center or surround recommendations?

Hi Baloo, one thing to keep in mind with the Gem XL is that it has angled drivers, which work out really well for surround. Here's the link to our web page for them. You can see pictures as well as descriptions. It's more compact than the Two's, and not quite as bass capable, but in some ways a better surround product. http://www.definitivetech.com/products/mythos-gem-xl
The Ten is a fine center, and the best we currently make in that form factor. I hope this helps smile.gif Best, Joe

Hello all,

Here is a link announcing something pretty cool. Definitive Technology has entered into a collaboration with 9-time Grammy Award winner John Legend. John is an American singer-songwriter and actor, who, In 2007, received the special Starlight Award from the Songwriters Hall of Fame.
He'll do some promotional work for Definitive, and will work with us on some future projects. Naturally, we're excited! Best, Joe
