Definitive Technology Mythos ST-L Loudspeaker Test Bench

Test Bench

Sensitivity: 91 dB from 500 Hz to 2 kHz

714deftech.meas.jpg

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Definitive Technology Mythos ST-L (purple trace). The loudspeaker was measured with grille at a distance of 1 meter with a 2.83-volt input.

The ST-L’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +4.45/–1.49 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +4.29/–0.68 dB from 200 Hz to 10 kHz. The –3dB point is at 26 Hz, and the –6dB point is at 24 Hz. Impedance reaches a minimum of 4.40 ohms at 284 Hz and a phase angle of –38.96 degrees at 158 Hz.—MJP

Def Tech´s ST-L V Golden Ear´sTriton One

Submitted by jca332001 on July 31, 2014 - 5:10pm

Hi there
I have been eagerly waiting to read this review, since the one about the Golden Ear Technology Triton One´s appeared acouple of weeks back.
I would like to know how you compare the speakers from each brand soundwise. Both have identical rating as Top Picks.
Do you perceive both models as performing similarly for both music and HT?
And thanks for keeping the scatological references to the minimal this time!
Thanks,

Shoot out time

Time for an in depth comparison since both scored perfect scores, which one is the pair to buy for <5k ?

Comparing the Speakers

Well, we all know that what sounds “best” is up to you ear. I would love them to produce an article comparing both GE Triton One & DefTech Mythos ST-L; but recognize the magazine will be hard press to produce such article –since their revenue stream also come from ads from these companies.

The little information I could scrape from both reviews; in addition to what people added on the comment section, is that both speakers are great; however, the build quality and specs looks to favor the Mythos ST-L.

The Mythos ST-L has what many would consider a better cabinet, since it’s made out of aircraft grade aluminum. In contrast with GE Triton One MDF engineered wood cabinet. Also, you have the comfort of having to control the bass with a remote control that comes with ST-L. The Triton One doesn’t provide this. In addition, the ST-L allows you to adjust the speaker’s level without moving it, thanks to redesigned footing whereas Triton One can’t.

The Mythos ST-L bass roll off at 26 Hz at -3db, weigh against to Triton One 27 Hz at the same -3db. The tweeter starts to roll off at 18 KHz with the STL traded off ultra-high-frequency output for “vastly lower distortion and smoother response at more relevant and audible frequencies.” The GE Triton One’s GoldenEar's High Velocity Folded Ribbon tweeter has “limited” vertical dispersion; not idea for a room with theater style stadium seating.

The GE Triton One Sensitivity: 90.5 dB from 500 Hz to 2 kHz
DefTech Mythos ST-L: Sensitivity: 91 dB from 500 Hz to 2 kHz

All of the above for the same price.

Some good points, but keep in mind the tweeter in the GE is on another level vs the dome model used in the Mythos. So, might be ok to lose some vertical dispersion to gain much better high end. I have the Triton ones on pre-order and previously had the Triton two's and never had an issue with the tweeter and height or placement. Far easier to set up GE speakers than Magnepan , Martin Logan, etc..

So really would be great to have a true comparison done with same equipment material, etc..

Love to see a head to head shootout like how car magazines compare an MB E class to a BMW 5 series point by point and even announce a winner. By the way, those car manufacturers advertise in the same publications.

It seems to me that S&V has provided us with enough information in the two reviews to draw some key conclusions save for the final listening acid test. There are always trade offs for any design decision. I can confirm this having worked a good part of my life as a design engineer. For example, the ST-L is smaller and more attractive which should provide easier spousal approval and perhaps a better fit based on where the speakers will be located. The Triton 1 has to have more 'kick ass' base just looking at the base driver compliment comparison (3 active, 4 passive on the Triton vs 1 active, 2 passive on the ST-L). The performance charts support this supposition with the Triton 1 only down about 6db at 20Hz vs 25db for the ST-L. The trade off at the high end has already been discussed. It's time for the real fun: listening to both of them.

Oops!

Submitted by BobHD1 on August 1, 2014 - 9:46am

The ST-L is down about 15db at 20HZ not 25db.

First of all If I wanted to compare, I don't know of any dealer who would sell both brands. It would be a conflict of interest and no quick sales. For the same price,the salesmen would have to favor one or the other and leaving the customer confused. All I can say is I'm 150% thrilled with these speakers. HD tracks sound fantastic and with a CLR-3000 for my center channel,Hometheater brings down the HOUSE! I'm waiting on some Audioquest rocket 88's for all 3 to Bi-wire,should be no disappointments.No time to go into detail,you have to listen to them yourself.

Available at your local Best buy, as we all know the place for true Audiophiles to audition high end speakers with the appropriate set up !!

Big Box Items

Submitted by chrisheinonen on August 2, 2014 - 4:43pm

Best Buy Magnolia sections also sell JVC projectors, OLED and 4K displays, Martin Logan and B&W speakers and more. Just because an item isn't only available at a boutique dealer doesn't mean the performance is worse.

That's Not Completely Accurate.....

Submitted by johnywad on August 6, 2014 - 9:14pm

Best Buy doesn't sell Definitive Tecnology. Magnolia AV does. A few of the local Best Buy stores in the twin cities redesigned a bit ago and carry some amazing product in their listening rooms. Unfortunately they still have a few Magnolia's that don't carry the same gear and they don't have the same well trained staff. From what the system designer( that's what his name tag said) told me, they are on commission and trained by all their vendors. And there are some amazing ones at that! Mcintosh, Sonus Faber, Diamond series Bowers and Wilkins, Arcam, and Electrostatic Logan's. I'm not saying all the stores that they incorporated Magnolia's in are perfect but the designer I spoke to has been in the industry for over 10 years and was very knowledgable on all the brands and answered all my questions accurately. You may not be as lucky as us unfortunately but the rooms were all acoustically treated and very well done. It was a treat to bring in my own discs and listen to the new Olympica III's from Sonus Faber with Mcintosh powering them. Oh, and you can also listen to these Definitive ST-L speakers as well since they have them in one of the listening rooms. If you have one of these upgraded stores in your town I think you would be pleasantly surprised!

Still not quite correct. Best

Submitted by simp1yamazn on October 15, 2014 - 5:16am

Still not quite correct. Best Buy has 3 different versions of their home theater department: 1) Best Buy regular home theater 2) Magnolia home theater 3) Magnolia Design Center (Magnolia AV depending on the part of the country you are in but VERY few are not Design Centers now).

Best Buy standard HT does not stock or display any Def Tech or other higher-end brands like B&W, martin logan, etc. However, they can order them for you if you know what you want.

Best buy Magnolia HT will have 1 or 2 listening rooms, mostly with entry level products from the better companies. Magnolia HT is just a slightly nicer version of the best buy HT and is nothing more than another department in the store. Any best buy employee can go into MHT and sell their products. There is nothing that Magnolia HT can sell that a regular best buy store can't sell.

Magnolia Design Centers are a separate sub-company fully owned by Best Buy. They are separate to the point that their system designers are commission based (unlike the rest of best buy), they do not report to the general manager of the best buy store, separate corporate management, separate vendor relationships, different inventory and POS system, different warehouses, and even separate tax ID. That's why they get to carry McIntosh, Savant, Lutron, B&W Diamond, etc. They can order virtually anything from the distributors they represent, even if the product is not in their systems as they can have product SKUs created for one-off purchases.

Reference: I worked for Best Buy for almost 5 years including standard HT, best buy MHT, and was one of the original System Designers when the Magnolia Design Centers were brought to the DC area.

No thanks

To each is own, of course.
But, if I am spending 5k on speakers, I insist on a home audition, or at the very least serious critical auditioning of several brands with a proper set up and in a private room. Also, knowledgable salespeople.Good luck getting that at a big box store like Best Buy. (I have nothing against those stores for other items, just in the case of Audiophile purchases)

def tech

Submitted by mikem on August 5, 2014 - 6:23am

A few years ago I had 4 2006TL and a 2500 center channel (it's been awhile re: model numbers)in my 12X14' theater room. From the first time I heard them in my room I was not impressed and I know this must sound heretical to def tech owners. Some time after I had them the amp in the center blew. Fortunately under warranty. If I had a penny for every time I re-positioned them I could pay off the national debt. At the time I also had, collecting dust, a THX Atlantic tech sub-sat system. After pulling the def techs out I replaced them with the AT system and then wondered why I ever replaced them. Just some thoughts.

Where do bass drivers belong?

Submitted by tnargs on August 7, 2014 - 12:11am

Fundamentally compromised by the fact that the ideal location for bass drivers is where the wall meets the floor. As the wall is not a good location for the mid and high frequency drivers, they are ideally separated. So, the Mythos is compromising sound for good appearance. Why not mention this?

And the peak in the response at 10 kHz needs attention.

One feature in common

Submitted by PollyChan on August 7, 2014 - 9:44am

The tweeter in either GE Triton One or DefTech Mythos ST-L is way too high above the ear level, making it less ideal for 2-channel music.

Ear Level ?

Submitted by true audio on August 31, 2014 - 10:07am

I'm sure that Def-Tech's engineers keep tweeter height in mind when designing the ST's and the ST-L,s.Maybe you haven't noticed but they do have an adjustable base. Poor excuse for two great speakers.

Pop goes the grill, and the grill goes pop

Submitted by DJV1972 on October 27, 2014 - 5:36pm

These speakers sound great! I have a pair, love them. One complaint. How the hell did engineering overlook the fact that the long throw woofer will push off the grill covers?? DF changed the grill from the ST to include an oval cut out for the mids and tweeter but no oval cutout for the long throw woofer! WFT DF? That is a let down! I don't want to run my speakers without the grill!
