Very interesting, Well worth the effort, I have built a pair of transmission line cabinets back in the 80s , just recently I replaced the drivers, to SEAS 8” 150w 8hm , and a tweeter to Mach , I coupled it from a HiFi machine from a 70s , they are only made of MDF 1” , the line is about 15 foot, and fire out the bottom, just over 5 feet in height, 10 inches across x 14 inches deep, I listen too Heavy Metal, Classical Music, Blues music,
Awesome work, Chaepau! Thus seems massive wood and your side walls are how thick? Overall weight of your speakers? How is your sound expression? Haave heard several Nenuphars and also sound good, voice outstanding, but lacking overall soundstage and very, very picky how you set them up in your room. Thanks a lot for sharing!
For now I’m like more the lii platinum but for some rock or dance is the sb acoustic. If you don’t wanna pay too much the best for price is mark audio.
Great information which will help me start my project. Thank you. What would did you use? Why did you decide not to use MDF or plywood? Thanks again Brendan
HI, I notice that when you build your cabinets (beautiful BTW) you're using what looks to be 2" of solid wood? Then no sound treatment in the cabinet. How does it sound? Does the 45 degree joints w biscuits help in terms of resonance versus typical butt joints? Thx
Hi the thickness is 43mm if you cut in angel 45 degree you get like surface of 60mm so is stronger joint. About the sound I’m impressed how much of base the small drive produce. The treatment I will put later I need try many different options.
What on earth IS this thing ? It looks like a quarter wave horn but it's not ... the mouth of the horn is severely reduced making it behave like a simple ported enclosure with only the wood thickness for the port length ...
And you could save yourself a lot of time and money by using good quality ply wood. It is actually superior in audio terms. You then simply veneer to your taste.
Schon in den 80ern hat man erkannt das Massivholz nicht das gelbe vom Ei ist für lautsprechergehäuse. Jetzt meint jeder einen Klangkörper bauennzu müssen. Trotzdem sind da resonanzfrequenzen. Aber egal!😅😅😅
@@janinapalmer8368 I would not call horn. It’s like folded Voight pipe. They measure with the bass reflex very low under 30 hz ,if I take the bottom out the base is starting at 50 Hz but is stronger. If you are interested I can sand you the files of the measures.
transmission lines and ported have high group delay in low frequencies and i can always here it with music.. i've recently added drivers and more amps and the result is cleaner bass and much more accurate.. I'm beginning to think ports and lines are a bit of a gimmick.. more power and more surface diameter beats any fancy design. especially if you are paying £££££ for that fancy design
