Martin Logan Dynamo vs HSU STF2

This is just my opinion... YMMV... but I do think that on the whole sealed subs (acoustic suspension) are cleaner and tighter, and are therefore better for music reinforcement. They seem to be "faster" -- at least they keep up with my planar magnetic speakers better -- and are more pitch accurate.

However, for most movies, where lots of slam, bam, boom, shaking, rattling, and otherwise just making very loud sounds such as car crashes and explosions, then a ported or slot loaded or passive radiator sub will very often give you higher SPL's and lower frequencies for less money.

Personally, I like the accuracy of the sealed subs -- such as those from ACI, Onyx, Velodyne, Vandersteen, and Martin Logan (to name a few)... but that's my preference, not necessarily everyone's.

Funny, because a lot of their speakers are ported

which ones are you referring to? i own ml speakers and they are not ported. they use electrostatic panels and their woofers are sealed. ???

Martin Logan Vignettes and Frescos are ported.

Did you see this in a CostCo warehouse, or on the website? Curious if I need to make a special trip to the local CostCo

i don't see this online in costco

I checked on the costco website recently as well and you are right, they aren't there, but the OP on this was from more than six months ago, so they probably don't carry them anymore?

this is basically the same speaker. So 1 speaker type out of how many?

That costcos and MartinLogan relationship was a fleeting experiment.

This is what MartinLogan had to say about it:

And here are some theories (by Hi-Fi dealers) as to what was actually going on. Funny read. Make sure to read down to "2nd Rick's" post. Also gives you an idea on the high dealer mark ups on your favorite speakers.

Actually it's two different speakers. The Mosaics are ported as are the Montage. The Claritys, Vistas, and Vantage are all bass reflex, in other words, ported.

So that makes seven models that are ported.

What were you thinking when you picked yellow for a font color?

I would love to know more about the ML Dynamo, if we can get this thread back on track. Costo policies, ported ML speakers, and font colors while absolutely fascinating don't tell any anything about the topic at hand.

Does anyone have any good first hand knowledge to share on the ML Dynamo?

Here is the test result of Dynamo by Tom Nousaine of S&V,

bass limit is 78db at 25Hz, average spl is 95 db from 25-62Hz

Same test for STF-1, bass limit is 75 at 20hz, average spl is 101db from 25-62Hz.

Output from One STF-1 is more than TWO of Dynamo. According to Hsu, output from one STF-2 is more that two of STF-1.

Here is a more lengthy thread about the Dynamo:

Do you have a link to this?

One of the link is here

You have to dig from previous issues of S&V to get the whole review.

Thank you.
