Impulse speakers


Just out of curiosity is there anyone familiar with this brand of speakers?

I own a pair the model Aria SE and I am very happy with them. They are designed by Keith Marshall. I have never seen this brand mentioned on any forum outside the Netherlands where they are build.

The aria SE that I have is 2.5way system it has 2 6.5" vifa premium line mid/woofers and a vifa premium line ring tweeter.

So does ayone know them or heard them besides me on this forum?

I have no ties to to people who build my speakers I just like them a lot.

I have no idea if it is the same company. Keith Marshall made transmission line speakers in the 80's/90's but the switched to regular front ported sytems. He now has 2 models the Spirit 2 and Spirit 3. I was thinking of maybe trading in my Aria SE for the Spirit 3. But I haven't heard them yet. And it depends a bit on if I get a nice trade in deal. I am a bit worried if you can have a nice bass responce with a 2 way system. The mid/bass is a Scanspeak 17cm Revelator met sliced paper conus with a Scanspeak Revelator Ring Radiator tweeter.

But if anyone has any ideas about them or heard the let me know.
the impulse line is arguably the benchmark for all horn loaded designs. the ta'us and the lali and others wrote the book on what a horn loaded design could be. they don't get discussed alot because they came and went before all the wannabes came along to snag the needs of the flea-watt crowd. Marshall is still at it, but the impulse line was a bolt of lightning for sure.
