Hint needed: QWTL with 2x Monacor SPP-200

Centvrion · 19th June 2011, 10:40 AM

I have a pair of Monacor SPP-200. Is it possible to use them in push pull configuration inside a transflex unit tuned at 30Hz?
How much does it matter if they have high QTS(=1)?What would be the result?

Something new... What is Transflex?

edit: never mind, found this

Centvrion · 20th June 2011, 08:09 AM

Yeah! That's a Transflex!...It's one of the 3(or 4?) pages from the original Jensen 1952 project.
I have already built a pair of towers tuned at 40Hz, but I used a pair of speakers (6,5") (as subwoofers) from a bass reflex system tuned at 40Hz, so, even if I didn't know TS parameters, I thought (right) it was possible: great result.
But now the "problem" is that a friend of mine gave me that pair of speakers and I don't know if they fit into a Transflex (in push pull, isobaric), mainly because of their high QTS (for what I know, reflex speakers have low QTS). Is this parameter so important for this kind of loading?
If anyone with some experience or simulator (as epa) could help me...
