Life wants more, so things need to be compact in a limited space.
I wanted to make a compact speaker with enough bass but distinct mid. My most importance in sound lies in life like mid. One of my friend FM Hari Iyer introduced a Peerless driver which has almost flat mid frequency reproduction capability in a tiny 3 inch cone, 3.5 inch driver.
I conceptualized a three fold compact pipe based speaker design that can have a line length of 28 inch yet actual height of just 14 inch. It still has driver space of 5 inch too.
A demo version made out of PVC pipe, thermocol and card board proves my design will work.
I then used 6mm mdf board for my required pieces, cut them from a wood molding shop.
I cut the PVC pipe by self. I secured those mdf plates with mseal. Later, I came to know that one can use a quick adhesive called Vetra as a most effective sealant and adhesive.
Here are some photos of those two speakers. The box you see in front of them is actually an active cross over, but this is used to show how a compact amplifier with UB and FM connection can look like.
I will add a drawing of internal later. that will explain how this can easily be made at home.
The sound has free mid and has good control depth till around 100 Hz. By my ear and if the SPL curve is true, I think high does not go much beyond 12 ~ 13K Hz. I am fine with it considering the intent of its use and the simplicity of its construction.
My FIL did the painting. I will add a driver cover with Black cloth later. That will bring more finesse to the product.
The total expense I think has not crossed 2000 INR yet. Drivers cost me 1300 INR for the pair.
I will be happy to help others who wants to make one such.
I have maintained approximately 1.25 X cone surface area. Link to the driver detail is here Products - PeerlessAudio.com. surface cone area is not available here, I have taken the same from a similar driver, probably from diyaudiocart site.
Below is the sketch for your help.
I would really love to have your suggestion on making it better. Anyone trying this and giving me feedback will be wonderful!
Happy listening.
Note: the box you see in front is actually of an active crossover (gift from a friend). I made the cabinet with 6mm mdf and Vetra adhesive only. This is just to show how will it look like as a complete system with one small amplifier capable to take USB flash drives and will have FM receiver. Infact the amplifier will be even smaller than this. This means one can have such a compact system with wonderful sound, for not so much money. I will update you all about the amplifier if my friend agrees to make one for me.
