FM who have been following my Fostex MLTL thread would know by now that this is a continuation of that thread below.

So why start a new thread.
Reason:
- The Metronome is such a highly DIYed speaker globally that it deserves a separate thread.
- The original Metronome thread in diyaudio.com is over a decade old and had several iterations to the original design. This design is even today discussed in the forum and is very active since 10 years. Probably this design would be the highest DIYed speaker till date.
- One of the major advantage of the Metronome is its extremely high WAF approval. In my case the moment i showed the images to my wife, i got a nod from her. Also the footprint is not wide on the floor but a little tallish towards the ceiling which should be okay for many. I was not sure if someone had build a Metronome in India (atleast not known to me).
- As i was working on various simulations with my box geometry was not able to conclude on what to finally design. Hence took help of TL gurus in other forums for a suggestion. Almost all of them told me to built a BLH design as the FE166en was more suitable for this geometry. The BLH was ruled out due to its largish size of enclosure which would have not been suitable for my smallish living room. Some pointed me towards a TABAQ and others towards a frugal horn lite designs.
- When i was exploring various designs landed upon the Metronome design in the frugal horn website. There are many published designs there but none for the FE166en. Also i noted that these designs when simulated in the LA were not very perfect designs considering theory and logic. Hence they would require considerable tweaking and cannot be blindly followed.
- It took me over 3 months to fine tune and tweak my design before the design was finalized and the final wood was cut. I am still tweaking for the right amount of stuffing. This part could not be finalized without the suggestion and inputs from our FM Kapvin and am still seeking suggestions from him.
- I will be receving the work in processs box today for my initial testing and measurements. Will post images of that as soon as its delivered today evening.
- I am planning to use my harmonic balance compensator with this design as i will be keeping the box atleast 5 feet away from my rear wall. Will post some images of the objective simulations.
