Default Considering first DIY speaker

Hi all

This is my first post in this forum.

I have been reading alot of the posts in the loudspeaker section and it seems to be a quite nice place and it also seems as a lot of you are quite skilled at making DIY speakers.

I am posting this post because for a long time I have thinking of getting my speakers replaced, because I am not that happy with the bass area. Though I am quite happy with the mid and treble area. The speaker I have currently is a pair of Snell J IV which I am using with a musical fidelity x-r100a and a Vincent cd-s3.

First I decided to look at some comercial made speakers, but in my search I stumbled over alot of DIY speakers and thought that this could be fun.

I have been thinking of the Ariel, thor and the proac clone mostly because they are the most documented speakers I have been able to find.

Though the thors will probably be to expensive and I am also quite concerned about the ariel's because the look as they are quite difficult to build.

At the moment I am kind of hocked at the proac clone because the cabinett looks quite easy to build and I have also read some threads here where people are saying they are good with rock and that is what I play the most. This is also a concern with the ariel's which I have read that a lot of people think will need a sub for rock.

What do you think of my choice with the proace clone? I am here thinking of my taste in music and my setup?

Also about the proac clone I have not been able to figure out to use braces or not to and if were to place them or it. The official page about the proac does not say much about this?

If you have some pros and cons considering building the ariel, the thor and the proac clone I would appriciate it!

If you could suggest others I would be happy also if you could direct me to some sites besides the official about the proac I would be happy

Thumbs up ProAc Response series

I myself own a pair of ProAc Response 1S (latest model is 1SC) and very happy with it throughout the years especially its mid and treble; and also the width of the sound stage. This speaker can easily "disappear". However, the bass, as you can imagine, is quite inadequate. (I must admit that this bookshelf speaker at this size has have extraordinary bass performance already). Up the Response series you will encounter they match up the bass performance with higher model. Like you, I'm very interested to build a 2.5 clone because I love ProAc sound very much. I'll definitely give it a try after I finished my diy poweramp.

I used MF to drive my 1S too. It is a class-A amp and I found only class-A and tube amp is good for it. People say ProAc people use AudioResearch tube amp to tweak their speaker.

I think if you are happy with your treble and mids; I would go with a sub: if that is feasable in your system. It is very impracticle and hard to achieve good bass in an all in one speaker design. Good bass needs a large woofer and a larger cabinet. With a seperate design you can always adjust the volume of the bass to suit music styles and movie pleasure. I myself have the (Ed Frias design) mains (I built these and they sound excellent) and supplemented it with a diy Tempest (15") sub. I'm estatic with the sound.

Hi MCH thanks for the suggestion.

I probably would get a really deep bass with a sub, but I don't think that sub effects is what I am looking for.

The problem with my speakers is that I find the bass muddy and not fast(I don't know if this is the right words but this is what I feel when I am hearing music)

The subs I have heard all have had the same problem with fastness and some of them with the muddy sound. Though I will say that I have not heard that many subs and most of them have been cheap subs, which was a part of a cheap sourround system.

I will only be using the speakers for music

Also I think that it could be fun trying to build my own speakers

Default sub

I don't think you would be disappointed with a diy subwoofer. A quality 10 or 12 inch driver would be fast enough to keep up with your speakers, and would provide more than just deep bass. I have a 12 inch Shiva from Adire Audio, and I can't believe the difference compared to all of the commercial offerings out there. It plays what is supposed to be played, not a bunch of noise like you hear out of most commercial subs.

When my neighbor first got his 15" velodyne, I thought something was wrong with my sub because his was so much louder. I realized after seeing some live performances that his sub was the one that wasn't accurately reproducing the music.

If your speakers can reach down to 80-100Hz or even less, a sub would be a perfect mate. Not only that, but a subwoofer is easier to get right than a set of speakers for a first project.

Good Luck,

Hi Austin

Could you please direct me to some nice places with easy good sounding DIY subs?

I was kind of hocked at the proac clone but I would like to take a look at some subs before I decide on which way to go. Perhaps you could be right it would be an idea trying a sub if that's easier as first project.

The thing I am most worried about with the speaker is the crossover how difficult is that?

If you pick a proven tested design and clone it you should get good results. You would just have to follow the plans and the crossover should not be a problem at all.

If you are thinking about building a set of speakers from ground up you might be in for a long session of never ending crossover tweaks. You got a couple way to do it actually. One, is to have someone with software to simulate a crossover for you. Two, look at different crossovers and build one and try it out. Three, build a cabinet and then have someone measure the drivers and create a crossover. Four, get measuring equipment and do it all yourself.

Simulated crossover is not going to be the optimal crossover, but it will be a good starting point and depending on your driver selection you could end up with a good sounding speaker. Measuring the drivers in your particular cabinet and then creating a crossover is probably the best way to go. Or you could just clone a speaker of course .

Hi Jean

At the moment I will stick with a proven design that's why I have looked at the Ariel, Thor and Proac clone. The proac is proably going to be the choice if I decide to build a pair speakers because of difficulty and price. I think it will be over my abilities to do the design from ground up.

I think I will start by making a list of what I will need and then see where I can get it and to which prices.

Question Isn't Musical Fidelity SS

The reason I ask is that the Ariel is "voiced" for SET tubes. If I remember correctly, Lynn Olson stated that Ariels don't sound good with Carey amps ( a well known tube manufacturer). I thought about building them (ME2 actually) to go with my HT but didn't in the end because the HT is SS.

I do think that the goodly amount of development in the Ariel/ME2 indicates a high probability that you would be happy with them if you were using SET tubes to push them. However, unless you go to the ME2 you need excellent woodworking ability or the ability to pay for it.

I believe Ariel/ME2 using a SS amp has a high risk of too much grief to get them sounding well.

Hope this helps.
