Welcome! Need support, you got it. Or share you ideas and experiences.
I have previous experience with an MLTL with this dimms....18"(wide)16,5"(deep)x45"(high) with an port 5" dia. put on the 3" distance from the bottom (lenght is 1"-to 3").The driver is mounted on the 8" (center of driver) from the upper.The damping material is on 30" fill from the upper panel.
So ...that is big enclosure.But is not that stomach hammer punch...you know...that is missing.I compare that with my small Technics (6,5" middle bass driver) in bass-reflex enclosure.On that speakers the bass shaking the floor but lack in details,voices and instruments.
The burn in perioud is probabily an issue?
My driver have an fs=52hz,qts=0,53 and an xmax.=4mm.
If I made an open baffle probabily I cutt on 200-300hz with an active sub.The Supravox will be free ...without any filter.
The amp from the sub. will have phase pot.(0...180 degree),cutt-off pot. 4th order Linkwitz pot. gain switch(x10) and volume potentiometer.
What do you think?
The Dragonfly ...I don't know what kind of enclosure is ...but I think is something in between Voigt and backloaded horn.
Do you think if I build the Dragonfly will have more bass comparing with my huge MLTL?
Please advice me to choose the right driver for an good sub. and if you could ...more details about Dragonfly enclosure?
i suspect the Dragonfly style- cabinets will offer you everything you are looking for, they also are easy to built and elegant looking. There are no comparable constuctions out there as far as i know - imagine that it is a bass reflex- enclosure using a port which is larger than the cabinet for a very good port- efficiency similar to a horn - or imagine that it is a very short horn which is floor- loaded to get a bigger virtual mouth- opening (like a corner- horn). This cabinets are a perfect fit for your room and placement, they need a solid wall in a distance up to 1,5m max. behind them to work corectly. I can send you are hardcopy of the cabinet- plan when you send me your adress as a p.n. (never write your adress in an internet- forum).
When you want to start directly with the active woofers two Eminence Delta 12LF which are reasonable priced should work ok. in a 60liters sealed enclosure each.
