My DIY bamboo enclosure for Tannoy HPD speakers. Sounds glorious and is rock solid. Looks great too( from the outside).

 

Very nice, I like bamboo as an audio gear material.

With the right skills and tools, commercial quality can be greatly surpassed. And that's both build and sound quality. The area that is sometimes not up to par is Finish.

 

I second that.

I was gobsmaked at the maze of bracings, divided areas, the general precision of the work, and the multiplicity of materials in the design.

 

Before that purchase, I had a look at a number of the DIY designs and they demanded wood-working skills far beyond my level, e.g. within a mm. They were anything but a simple box. Since I couldn't ensure the quality of the work I was unsure how the sound quality of the design could be assured.

 

If you are considering DIY check out the designs and see whether you have the talent.

 

All speakers aren't necessarily the boxed design - c.f. Open-Baffle Speakers.

Its very difficult to build those kind of speakers. I assume you're talking about time and phase correct speakers given your description. The first order xovers make it very difficult to integrate the different drivers, but when they get it right, the coherency achieved rivals planar speakers.

 

I have yet to build mine (open baffle) as I am in the research/design phase, but I believe it to be less complex than building boxed designs, although I also got two (boxed) loudspeaker design handbooks recently.

 

There's much less of cabinet design and bracing and then of adding the damping material inside, etc...

 

There are a few things you need to research first though, and that is the principle of building one and also select the proper drivers. The rest of the build is far less complicated.

Not for a time and phase correct speaker. Working with first order xovers and getting the drivers properly aligned is very time consuming. That's why no one makes them. Of the 3 larger high end speaker companies (Meadowlark, Vandersteen and Thiel) that made time and phase correct speakers, Meadowlark went out and it looks like Thiel is phasing them out as well, since Jim Thiel died. There's been some articles written on this topic over the years. If you're interested, let me know and I'll see if I can find them for you.

 

 

Not difficult if you understand:

 

1. It's easier to time-compensate when your crossover is run on a computer

 

2. The 'principle of building' can include allowing the drivers to be physically moved back and forth

Things are always easy when you're talking about doing them, but can be very different on the attempt. Offhand, I can only think of 2 companies in the world that are actively developing time and phase correct speakers; Vandersteen and Green Mountain Audio. If there are others, I'm just not aware of them. How many DIY's make time and phase correct speakers? I've never seen one. And if I did, I'd want to see some proof to back up the claims.

 

No idea how many DIYers do it, but one place to check is over at diyaudio.

 

I know I'd do it if I weren't using a computer cross-over/processing and it would be in the design of the arms/support for the drivers.

 

Then again, in all my audio-related DIY, I take the approach of optimising transient response, which may not be the goal of others.
