Found this old experiment of Romy:

The more I think about the mode I am getting excited about the
direction the Remedies went. I see now how I can convert
the problem that I have with large inbound baffle into actual advantages. The
new plate will be probably 1.5”, heavy coupled an...

[quote user="haralanov"] Rakesh, during the last year, there were some very important moments in my own realizations about the methods of low frequency reproduction. I totally abandoned my Scanspeak bass modules and now they are resting in my gar...

I see what you mean. I still would go for 10" or
8" drivers. I happened to love the scanspeak (make sure that it was exactly
my model and the box is made probably: large and over-dumped) but if you do not
like them then it is fine and you need
t...

This is very interesting observation. I am in away envy that Petar went for a set of large woofers (4x23”!). This is the way to go! Unfortunately I did not experiment with it even I had the drivers and means to do it. My problem was with the fact...

I’m new to this outstanding website and I found it has really educational value and antimoronizating information :)
I’m still in the world of direct radiators and I’m looking for the ultimate midbass channel solution. At this time it’s still impossi...

Hi Roberts, Romy and others,Before this thread vanishes in undeserved obscurity, I have a question or two for you. I understand that the issue is a complex one and should be addressed with more care and paying attention to detail than I am do...

Simulations cost nothing, so I continue my a bit random walking and played a bit more with a PR sub idea, inspired in some way by Romy's la...

Thanks Romy,
I would have thanked you sooner but I had the day OFF of my day job today and had no time to post until now.
*cracking up*
I had a feeling there was no easy answer, wasn't sure if I was missing something, had scoured posts for a whi...

Thank you Rowuk for the explanations.
[quote user="rowuk"]The Tannoy driver moves at 32 Hz, the passive radiator can only move at its tuned frequency - 30 Hz.

I understand what you are trying to say,...

i suspect that some MF energy coming out of scanspeaks are actually box reflections [/quote]
Hey N-set, as I am back listening to my Dannoys and I listened again about a week ago for the passive radiator and found -...

Wilson’s
advance reviewers/sellers have said Wilson has gone back to paper (all ScanSpeak)
drivers, with silk tweeters. IMO, this should
be good for tone and texture, but it will likely change amp interface. If I were interested in the Wilso...

Jarek, my experience affirms that many “listening rooms”
are overdamped, and you can always put a rug or rugs on the wooden flooring
where you want it/them. And I have been able to get good sound in weird rooms.
Basically, regarding rooms, “to...

[quote user="anthony"] Briefly, I tried altering some operating current on
the valves and now have a better understanding of how DSET can be used to shape
the sound. It is one thing reading about it but another thing entirely
when you turn a knob...

It is well known fact that all loudspeaker enclosures contribute to the sound of a given acoustic system to some degree. Unfortunately the resonances of the baffles have constant monochrome character and if they are too prominent there is always ...

[quote user="Romy the Cat"] That is very good approach in my view. The
problem is in this approach that you have to have high sensitively speakers
that you would be able to use with that test full-range Milq. The behavior of
the Full range Milq wi...

[quote user="rowuk"]
Impossible. A passive radiator can NOT change its tuning frequency on the fly. It is a Helmholz resonator - one single tuning frequency. It is also NEVER in phase, it is always late as it takes several cycles to ...

user="anthony"]Hi Romy,
So it is time to think about the bass output
transformer in my DSET. My bass channel will be 8 x 25W/8565-00 each side
set in a sealed box and will cover the frequency range below say 100Hz.
These drivers can be ...
