TL for silver flute 6.5"?

[tuxedocivic]

Cool idea Dave. I wish I had a plan for my SF W20RC-08's. I'm using them to 300hz with a 3" full range over them right now, but it's kind of a temporary thing. Even though they're really good. After that, I'm not sure what I'm going to do with them. Would be fun to do a tower type thing like this. Don't know the first thing about TLs other than they're long 😀

Measured specs?

That could be experimented with. Just had it in my mind to put tweeter at top, mid in middle, then woof at bottom, as in previous vented box. Hmm.....

Any progress?

There has been progress, but not on that particular project.

I embarked on a garage re-model project in November, after getting married in October. The man-cave has been a focus lately. (pic attached)
An adjacent work shop has been another part of that project. Still need to move more things from storage and organize both rooms. When will it end??!!!! 😱

Lots of projects like the 3-way/TL are still only ideas. 😱

I stumbled across this thread last week and bookmarked it. I just got finished with a small bipole MLTL using the buyout tangband 3" and a rear facing helper tweeter.

I was going to use some of the specs on this thread to possibly build a bipole MLTL using the 4 ohm 6.5" silver flute with the same rear facing helper tweeter.

The gentleman that have used the 6.5 SF, can you let it rolloff naturally with out a crossover and just use a high pass xover for the tweeter?

Thanks RyanI

Here are the manufacturer's specs on the 6.5" SF wool cone 4-ohm
(my measurements were similar, IIRC)
The Madisound Speaker Store

There is some break up to avoid at 5 kHz, so no, it doesn't roll off nicely. Also, there is something going on at around 800 to 1 kHz. I used a steep slope to cross over near 800-900. Tuxedocivic uses his below 300.

Up to 600 or 800, the response is very flat. It's not very efficient, however.

hope this helps.

Thanks for the quick reply Dave, It's appreciated. Sounds like I'll be looking for better candidate for my experiment.
