    Small horn monitors

    I recently finished a pair of horn monitors and thought I’d share a few pictures. Going into the project I wanted something small enough to fit on the shelf in the family room and still have some of the dynamics of a larger horn system. The final boxes are about 18 x 20 x 10

    The speakers are two ways with 708g woofers on the bottom and 2407h on the top. The horns are similar to the ones in the 1200hz smith horn thread, but with a 45 degree Westlake lip.

    The 708g is a great little woofer and is used the L3, L5 and L7. It works well in a small ported box. The impedance is closer to 4 ohms than 8, though. I thought about hooking them up parallel with a network similar to a 4430’s, but was concerned about the overall impedance falling too low. In the end I decided to run the pair hooked up in series

    I tried both the small 2408h neo drivers and the 2407h. Of the two, I preferred the sound of the 2407h. They just seem a little more open and less constricted.

    The crossover is based on the NL200t3. I made a few changes to adjust for the horns and bring the crossover up to about 1200hz.

    Very Tasty

    Lovely work John. Did you keep any pics of your work on the horn throats, I'm sure a few folks would be keen to see that.

    I had them upside down for a while, but found the duck look a little distracting.

    When doing some measurements I found the vertical beaming of the horns wasn't as pronounced as I thought it would be. The measurements on the bottom are made from the listening postion, moving vertically down from horn heigh to sitting position on the couch.

    They look absolutely stunning in their final position on either side of the fireplace . . . wow. Are you using the bass bins with them here, and they're just not shown?

    No, these are LE120H boxes from another project. I wish I had someplace to set them up and not get in trouble with the family.

    Interesting traces, John - not as much variance as I would have expected.

    Tell me - what is the "active curve" trace...?

    I think that is just the residual noise in my sound card and preamp. In the RTA program you can lable saved curves, but there is always the "Active" curve in the forground. Here it's with the pink noise turned off.

    btw: SynRTA is nice little free RTA program
