High Sensitvity = good transient response ?

How do you make an aperiodic transmission line ? I would assume that the TL was terminated in some type of resistive ( probably stuffed ) vent.

Kind of reminds me of the Shahinian Obelisk. This is a TL that terminates into a passive radiator. Both would be somewhat out of the ordinary approaches. Then again, TL's are not very mainstream to begin with. Sean

Sean, they don't give the details on the website, other than it is a line with "valves" to control air flow. That sounds like what you are talking about with the stuffing. I've never experimented with something like that before. It seems like an interesting concept, but I don't know how well it would work.

"valves" to control air flow? Sounds like the the old Proacs(?) with straws stuffed in the ports (semi ports or multi ports or semi passive radiators?).

Learn something new everyday. And I thought that the covering on Brentworth's opening was the driver. I have only heard 2 SET as dealers don't carry this stuff. Sam Tellig talked with Mike Sanders re Quicksilver Mini Monos / March 2001. Page 36 I quote:
"The distortion is so high with Single-ended that when you put negative feedback around it, you get distortion of distortion. . . The distortion is multiplied so the amplifier sounds worse"
"The annoying thing is the higher distortion, because you don't get the distortion cancellation that you do with push pull. . . So you can't get rid of the distortion of single-ended with feedback: after a while, that distortion just eats away at you".
This is about all I know about SET.
I've only been in this hobby 1 year. Sometimes I think I should've gotten another boom box :)
Went to 2 live shows last month and the musicians and singer were playing through mics / amplifiers / speakers and even though their systems really did have a lot of distortion compared to audiophile stuff somehow it was better. Seemed like that "immediacy" thing people talk about with SET. So I'm interested in SET stuff.

Aperiodic designs seek to combine the damping of sealed speakers with the efficiency and extension of ported speakers. You pick up bass extension and efficiency due to making use of the backwave from the driver ( like a vent ) but the impedance remains low ( typically even lower ) at resonance like a sealed design. The high impedance peak of a vented design is part of what contributes to the "bloated" or "uncontrolled" low end response that lacks definition.

While it sounds like a phenomenal trade-off ( best of both worlds type of situation ), aperiodics ( also called "vario-vents" by Dynaudio and some DIYer's ) don't sound like either design. How such a design would work in combination with a TL is anybody's guess. Obviously, one would have to listed and see if it was their cup of tea. Sean
