Any Feedback on the Nightfire NF-DT1 TL?

[Forster]

Hello,

My first post - so greetings to one and all.

I am considering building what looks like a very interesting and compact transmission line speaker designed by Nightfire Acoustic Technology in the UK. I searched the forum and found no allusion to the speaker system.

The plans are here :

I wonder if anybody has experience with this design, and if so could inform me the sound quality.

They will be played through a Quad 405 system, a Luxman D-117 CD player, and Sansui 838 for vinyl.

Best regards - Forster

Hi,

I'll give you the benefit of my considerable experience and suggest
you steer well clear of this design. It could be good, it could be awful,
once you've built the cabinets you'll be well stuck with it.

Have been going for years, you should be able to find feedback on
them, though I understand they have a pretty decent reputation.

Avoid this Nightfire thing. Any time a manufacturer starts to suggest that stuffing should be used to increase the effective length of a line, rather than simply damping those higher harmonic resonances that couldn't be engineered out by careful design in the first place, start walking.

The IPL kits are decent examples of traditional TLs; I haven't heard anything to suggest otherwise, and the MathCad sims I've run look positive to me.
