Hello, I am new on this forum. I would like to say it is very good, I already found some new interesting information and projects. But I came here because I need some advise...
I am very young so I don't have enough money for HI-END speakers, but I am DIY fanatic 😀 So my aim now is to build low cost high fidelity system. I have chosen some speakers and pairs of them, but I don't know which variant is the best, so maybe someone could help me
Also I am going to use BI-amping because there are no chances to me to make good passive filters...
Here are my variants:
1. Subwoofer + Fullrange
SUB - W5-1138SMF - TB speakers 5 inch paper cone subwoofer - Europe Audio
FR - W3-316B - TB speakers 3 inch PPM cone full range - Europe Audio
or W3-881SJF - TB speakers 3 inch polypropylen cone fullrange speaker - Europe Audio
( 15L ported box -3db 30Hz, Xmax 9mm so it should give me deep and good bass for its size, but I am scared that it will be not enough and also its sensitivity is only 82 db :/ )
2. Peerless SDS134+vifa BC25TG
830656 - Peerless SDS-134-THP 5.5 inch woofer coated paper - Europe Audio
BC25TG-15/04 - Vifa 1″ ferrite magnet tweeter - Europe Audio
(Ported box 25 L -3db 36 Hz sensitivity 85 db, but xmax only 4 mm, some people said that this is very good speakers, but I am confused because I think there will be very low amount of bass, so I would put big sub that goes to 20 Hz.)
3. Peerless SDS164+vifa BC25TG
830657 - Peerless SDS-164-THP 6.5 inch woofer coated paper - Europe Audio
BC25TG-15/04 - Vifa 1″ ferrite magnet tweeter - Europe Audio
(Ported box 35L -3db 40 Hz, as for its size this box is big, but its sensitivity is not bad 89db, also I am confused of low bass :/)
My main goal is to make floorstanders that can play music without sub, and if there would be a need of it I could put a sub near my floortstanders for extra extended bass...
Sorry if I made mistakes, this is not my main language.
Thank you for your answers 🙂

'BIB' [bigger is better] rules when it comes to [mid] bass reproduction, so #3 in a MLTL or TQWP.

I have one more question... I red an article ,,accidental MLTL design '' but it is very hard to understand that MLTL for me. I wanted to build vented box about 30-35 L for sds164, but then people said that I should make MLTL box.
So can someone help me with that ?
I made some calculations but I don't know if it is good
340.29m/s : 40Hz = 8.5m
1/4 of wave 2.125 m ( so this is the lenght of the all labyrinth)
And then Sd of my speaker is 141cm2, so my labyrinth's cross sectional area
anywhere should be 141 cm2.
I want my speakers to be 90cm tall.
Is this all ? I think it can't be...

The accidental MLTL design routine is OK, but with driver specs we can do better.
90 cm is a bit short for an unfolded MLTL, but better damped than a simple reflex due to typically having more net volume [Vb] + some ¼ WL pipe action damping the vent.
Anyway, at a glance it looks like it will be at least ~47.452 L, so using 19 mm BB plywood, the cross sectional area [CSA] = [47.452*1000]/[90-3.8] = ~550.48 cm^2 at minimum.
Normally, the driver would be down ~1/3 or 2/5ths with the vent either around 4/5th or near/at the bottom and looks like it will need to be the closest [larger] metric size pipe diameter to 2.5”, with length to be determined later.
