Default ob for life

2 of the last 3 speakers ive used were ob.

Crap drivers in crap baffles.

But such a relaxed sound and i loved them.

Even compared to a pair of dm302 and energy boxes.

I dont think ill ever build a box again.

Currently using a fullrange 3" on the winged baffles i posted in fullrange system pics.

Im so happy!

I thought OB was the best until I heard a tractrix synergy.

Good to hear you like you speakers Etocynned
I can honestly say I've never listened to an OB, but have heard a few 'boffle' speakers that sounded good.
I dont think my GF would go for OB's in the lounge as they would spoil the view from the lounge window.
I'm on a 'dual concentric' trip at the moment (4" KEF's still need boxing, currently listening to Tannoy 609's)

How interesting.

My previous system with tractrix (Oris) midhorn was not a synergy but still lovely, I missed it.

Now I've been living with OB for 2 years or so. It's easier to integrate with a DML panel to make a three-channel system.

Currently in a simple is better phase.

Cant do the eq/xover thing to make the synergy horn work.

Perhaps when things turn around.

Im just awed by these ob speakers though.

I am reminded of the sound of Martin Logan speakers with them, the openness, even though i can tell the fidelity isnt there.

I hear you about simplicity. In my slot loaded OB (SLOB) setup I lucked out with the built in XO in a Breeze Audio 2.1 TPA3116D2 amp matching perfectly to give me this:

Note that there was *NO* EQ of any sort used - only level matching done with sub and tops volume knobs.

The natural fall off from the 5in OB top just perfectly matched the sub amp falloff combined with the a slot loaded open baffle response of the woofers to produce perhaps one of the most natural sounding and dynamic speakers I have built. The 5MR450NDY driver is an awesome OB driver if you are high passing above 300Hz.

Check out the sound clips.

Simple is better, I've got TC7 peerless on 3X3 foot baffles in my workshop and they are a pleasure to listen to!

I finally took the time to do simulations in EDGE for a proper baffle to mount my Alpair 7.3's.. Not so simple a system with MiniDSP and 15" DLFA's In H-frames but the new baffle just took it from pretty good to awesome.

Had to remove most of the eq I had on the 7.3 except the low shelf and a few dB lift in the top end.

First time In years I finally really look forward to listening to music every day!

My original baffle with the driver mounted in the middle had 15db simmed fr variance. The new one Simms with only 2.5db. Took me 2 hours to go from good to awesome.

Happy days!
