If I could run an audio manufacturer, I would like to research and develop and sell an ideal 3-way speaker unit plus a design that has a bass reflex port on the upper front side like DENON's SC-L30.

The woofer is Yamagiwa's original Klipschhorn 18inchi(46cm) woofer (Yamagiwa Special).

The squawker is a squawker designed like B & W's 800 series rugby ball.

I think the ideal tweeter is a JET type hail driver.

With such a combination of speakers, the bass reflex port of the Klipschhorn woofer + tweeter (a heil driver is different from a normal tweeter, so there is room for research) is like the DENON SC-L30. I want to make it a nice structure. Bass reflex duct close to a gramophone. It seems that it will be an ideal speaker that is easy to listen to, even if you have some deafness or some deafness. As you can imagine, if the Yamagiwa Special is already a bass reflex duct that emits bass from the side or from the bottom, and it is a winding bass reflex duct like a snail of a denden insect or a gramophone, I dare to hold the bass reflex duct on the upper side. It may not be necessary to come. I'm sorry for the amateur thinking.

We would like to make the saran net similar in construction to the Monitor Audio Bronze 2, with a magnetic system that is easy to attach and detach.
