Post Subject: Thoughts about above.Posted by Romy the Cat on: 8/31/2021
The above in Red color the response of Tannoy 10” Red
LSU/SF3LZ driver with default crossover mounted in in Dunlavy TSW-IV Tower in a
position of third driver and loaded to 4th 25W/8565-00 driver as passive radiator.
In blue, the response of the same Tannoy driver but complimented
with another pair of the same paralleled 25W/8565-00 woofers from the same
enclosure but acoustically isolated from Tannoy and actively driven by the same
amp with no filter. This is right channels, which is pretty much at the middle of
my room and has no wall gain. It looks like it is out of phase if you ask me…but
the reversed phase not better. There were zero efforts spent there, this is just
a first blind connection. Still, the entire assembly sounds remarkably pleasurable.
I was trying to drive Tannoy with Milg and woofers with my
SS amp, effectively bi-amping with second order crossover at 35Hz. It was VERY
nice. Then I took it further and put the LF section on transition slop,
crossing it at 15Hz and gain 10dB, it gave me more or less pure 20Hz but the
drivers were strenuous for the room of my size and I felt some LF compression.
Now, where to take it? Not quite sure yet. I do not want to
drive it with Milq and I would like it to be cold-running, all time on segment
of my installation. To bi-amping is a good idea but a paralleled woofers have
near enough sensitivity to work along with Tannoys. If not, I can throw another
2 woofers to help that would give a nice array of 4 woofers per channel to
support the Tannoy.
I do not mind driving it with one amp, but I would need to
have a good SS amp. I do not want to use older Lamm M1, too big, too hot, and
too bulky. Something like reported Lavardin would do if they have one input and
no volume control, but I would probably need 100W…
A very interesting configuration.
I am still getting familiar with it sound as the Tannoy DC drivers are different
animals. One way or another so far the Dunnoy is in a way ridiculous but a very successful project.
