Why DIY?

In a nutshell, DIY is for those who want more for less as well as the satisfaction of having created something exceptional.

I found a kit at Jaycar (no longer available) which included a Leap-designed crossover, drivers and hardware.

Expect to pay AU $800 - $1100 to build this speaker, depending on your suppliers and choices, particularly with respect to finishes. For a much less original comercial equivalent you can expect to pay at least AU $3000.

The drivers

Tweeter:  1 x Vifa  D25AG 1" aluminium dome
Midbass: 2 x  Vifa P17 6.5" polycone

Information on these drivers can be found on the Danish Sound Technology website. These drivers are both very good value for money and are good all-round performers.

Listening Review: how does it sound?

Overall: This is a well-rounded and capable speaker that is well suited to many types of music. Vocals are clear and neutral. The bass is natural and extended.

The transmission line design yields a deeper in room bass response than a vented alignment. The bass is less punchy than a vented alignment, but is more natural sounding and more satisfying with music where you want to hear subtlety and musicality in the bass. The result is particularly satisfying with acoustic bass.

For more information on transmission line bass, refer resources section of this site.

This speaker is best suited to medium or large rooms, the latter if you aren't looking for full range high SPL levels. In a small room it is difficult to place them well.
