Sensitive Wide Range OB - Update - Tonemaster

[Magnetar]

I have these performing pretty close to ideal for me. A real Grand Slam sonically - a step up in tone and believability over the previous contraptions using mid horns - Midrange is modified Eminence Lil' Buddy and treble is B&C DE10 in an Eminence APT80 horn - modified of course to fit.

That horn is too small, those drivers don't cost enough, and there's no hi-tech box to put them in. It can't possibly sound any good.

LOL - They were about 200 bucks a channel -

The sound is like gold

If you don't mind me asking, where are you crossing that Lil' Buddy at?

Magnetar,

Good going! That is of course open baffle with wings right?

The modern 604 in the shallow horn in the background looks interesting. How did you machine that? Do you have access to a large lathe? I want to do something similar in diameter with a bunch of black walnut chunks I have (conventional 1/2 wave diameter and length deep parabolic curve horn for a small cone driver perhaps 4-5 inch) but would have to make a huge powered turntable and control arm for an electric die grinder or router motor as the cutter. A lot of work for one pair of wooden horns.

250 and 2500 cycles.

They are triamped.

They are really good at emotion - they draw you in and envelope you in emotion- best I've heard yet in that respect - goosebumps, toe tappin', baton wavin', air guitar palying ect... to the MAX

My friend Victor Sierra has the big lathe. I have the horn in sections all the way down to a 1" compression driver. Here it just functioned as a waveguide. The drivers are PAS 2580 with 4" coil and 2" entrance loaded with a large format compression driver. Think Super UREI - I like the hemp guitar speaker and the little 1" B&C compression driver over it though. There is really no contest, although I never completely perfected the crossover for the coax..

Thanks Mike.

The spec of Lil looks interesting.
What does the mid range sound like?

How did you modify your Lil' Buddy may I ask?

It's not exactly neutral but measures really flat in the midrange - I have more accurate midrange drivers like the JBL 2123 that sound very good but don't sound like this. An analogy would be the accurate JBL sounds like a good solid state amplifier where the Lil' Buddy sounds like a direct heated single ended 45 triode amp. In other words it's fast, direct, warm, lush and romantic. More 'whole' - probably has just the right amount of even harmonics distortion to please me.....

The mod is simply removing the dustcap and installing a phase plug - the plugs in mine are temporary - made from wax.. The driver uses hemp for the cone and has hemp for the surround - it's different
