I'm not sure - that's why I'm asking - but I suspect this would probably change the characteristics altogether.

YES! Don't do it

Driver and vent position in the line do indeed affect performance -specifically the degree of excitation of the line harmonic modes. They need to remain as-is; it's part of the design of an MLTL.

If you lifted the drivers up, you'd be exciting all of the cabinet modes; fundamental (which we want) and harmonics, which occur at even multiples of the fundamental in an untapered line (we certainly don't want these) equally. A rougher response will result.

At ~$160 + shipping per tweet I'm glad he turned down the volume.
Glad you and your speaks made it. Gave a us nice reference as those drivers are well known. It was also nice to hear the revised cabinet. I'd never heard the original but these seemed just fine!

You have to assert yourself a bit more!!!
Bring music- I was disappointed more people didn't do this. I think we proved that no one was humiliated for playing a particular cut, so don't be scared! bring what you like.

Throw yourself on the volume control to preserve your speakers- after all, they are your property!. I suspect that the amp was distorting. It was easy to overdrive both amps and speakers because the room was quite big, and the quality of reproduction was generally very good, which as we all know, keeps you from realizing how loud it is.

Again glad you were there...the quality of finish on your speakers was neigh perfect IMHO

Mark,
Thank you for the very kind words concerning my speakers. I had never heard my speakers clip before so I did not know whether it was the amp or my speaks. No damage done either way. I honestly had meant to bring a couple of CDs with me that day. Allison Krauss live is superbly clear and the Dobo solo is outstanding. Gee, I hope I didn't hurt anyone's feeling with my music comment.
Thanks for making me feel at home and not too ignorant (which I am), Wonderful bunch of people and Nelson Pass.......Well what can you say about Santa? Wow! He and his son were having as much fun handing out goodies as we were receiving them. Better stop here or they'll accuse me of thread jacking...sorry..
Ron

Thanks. As I suspected.
What, in your opinion, is the best place for the port exit: back, front or below?


I just looked at greenie512's nice smallThors. They look great!
But one thing puzzles me: He seems to have added some kind of stuffing along all sides of the inside walls.

Click the image to open in full size.

I thought I only had to add stuffing in the upper half of the smallThor? How did you guys do? And how did you secure the stuffing from gravity - keeping the stuffing from sliding down?

Sorry about all these probably stupid questions, but I'm new in the game and being a foreigner I might not readily catch everything...

Ron,

I was very glad you brought your Thors to BA. Hearing them was one of the high points of the event for me. I almost started a Thor project a few years back and it was interesting to find out what I'd been missing. A great deal it turns out. The amp being used to drive them was AR2's Aleph 30 (30 W/ch) I believe. If so then that would explain why there was stress on the loud bits. Trying to run Thors that loud in a room that big with 30 watts is a serious push.

Thank you again for bringing them. It was great to meet you and talk about your project. And yes, I'm one of the ones who stopped talking and turned toward the front of the room when your speaker demo began.

Graeme

Yes it will. The offset of the middle of the drivers from the closed end of the line is very specifically choosen to help kill ripple.

Thors IMO need at least 200wpc in an ordinary domestic setting -they'll be idling most of the time, but they'll need that in reserve to fully handle dynamic peaks. I'm sure they'll sound good with lower power too, but if you want to maximise their capabilities, the more clean power you can pump into them, the better.

Default Well then......It was the Amp!

That explains a lot!!!
Even thou they sounded good, the Thors did not have the same sparkle and snap with deep healthy bass as they do at home, or when I took them to the High End Home Theater store in my town.
(Not Best Buy)
At home 16' x 30' they are exempliary(sp?) With the SS Conrad Johnson 250Watts.
Mr.Moose, P10 & Martin......you guys are the Shiznet!

Ron
