Hello,

  New to the group.  Have built a few DIY amps (mostly from Nelson Pass - Aleph j, F5 turbo, tube preamp).

    Been trying to do a few open baffle projects and have gotten bit by the OB bug now.
Would be grateful for any input on the OB projects, also wondering who if anyone took up the Hawthorne Audio products.
   I had heard great things about them.

Thanks!!!!!

Hi,
Please dont be shy to post photos 
This is a inexpensive DIY project from an AC member,
It have only four (4) parts:
Eminence Alpha15A + 4.7mH + Visaton B200 and a MDF baffle.


Other option are the Lii Audio F15 FR driver $399/pair, not each.
Here Decware OB with the Lii Audio F15 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.

My personal choice is the Lii F18 in Single Driver configuration, but if you make question of wanting a 2-Way speaker you may want a bigger woofer than the Alpha15A, so there are W18 inches and W21 inches from Lii Audio, personally I dont like these two VCs woofers, they are hard to drive with a small tube amp.
