Hi all, just joined the forum.
Looking at a possible GR Research build in the future and wanted to familiarize myself with other builds first.

Building your own loudspeakers can be rewarding and frustrating.  Frustrating because you'll suffer from proud papa syndrome, can never audition the end product beforehand, and doubtful that you'll ever go active.

Hi Doug,
Today audiophiles can take vantage from inexpensive and transparent powerful Class D and GaN-FET amps and recently with Lii Audio, take vantage from inexpensive big cones full range drivers, this will save a lot of money hence no crossover and no enclosure need.

This is a inexpensive DIY project from a AC member, it have only four(4) parts: Eminence Alpha15A + 4.7mH + Visaton B200 and a MDF baffle.


Maybe you may like look over these others OB projects:
Lii Audio F15 FR driver $399/pair, not each.
Here Decware OB with the Lii Audio F15 FR driver:

If one have a woodworker is possible try the Lii Audio F15($399/Pair, pair not each) 97dB/8Ω and benign impedance curve suited to OB or Bass Reflex box or the F18($540/pair), no Crossover, no Tweeter beaming, no Phase rotation, no driver sensitivity loss, no Harmonics loss, no Retail price.

I always would prefer the Lii F18 single driver, but if you make a point of wanting a 2-way speaker you may want a bigger woofer there are 18'' and 21'' from Lii Audio:
