Post Subject: Might...... be....Posted by Romy the Cat on: 7/11/2017
I was thinking and thinking last couple days what to do with
my lower midbass situation. I do need to use 2 drivers per channel with 100dB efficiency
to get the dBs I need to match Macondo and Milq’s bass channel gain. I do want to use Vitavox 15” for their stunning
upper bass. I do not want to go for ported topology and the Vitavox15 need room
to gasp. So, I might go two china’s midbass. I can get a pair of Altec 151G let
say and make two of them to run lower midbass
and then let Vitavox to run a higher midbass, making let say 50Hz as
divider point. With low order filtration the filter will be irrelevant and I am
afraid that with higher order filtration I will lose the entire “space”. I do
have room for more enclosures in there…. However, it does not sound elegant to
me…
The only option that I feel is on the table that is cleans
and would not have too many unknown would be to take advantage of my listening
room profile and implant a midbass horn in there. The idea looks very elegant.
It will not hard to build. I will use a pair of Vitavox 15” in 10” hole per
driver, not the 8” as I use to do before. I think the Vitavox 15” needs to have
less compression and to be more “freestanding”. With such a large whole the
horn will not have a long neck in beginning. I will have 7 feet before the
first bend and pretty much unlimited length to the horn mouth. I can’t show it
on the picture but I will have the 3 ways mouth opening that should be more visual
appealing. If I go this direction then I need to circulate where will be the
mode in the bend and where the mode will be in proportion to the room and the
rest of the speakers. It I possible that will be able to spread it or to use it
somehow. The interesting thing is that even it will be a relatively large horn
but it will be not a huge time delay, just 1-2 msec.
I need to measure everything and to plan everything if I go
this route. For sure it will be the best use of my Vitavox drivers and I am pretty
sure I will be to get the SPL I need. I wonder, would it be worth for me to
take a week off and to render this project?
