Interesting experience with two very different speaker designs


I wanted to relay my experience with two different sets of speakers in hopes that it might prove interesting and/or help some folks.

My current speakers are Tekton Electron SE with a Pass XA30.5 and a MicroZOTL2 Preamp.  I was absolutely loving the sound but I started getting into the DIY open baffle thing.  I started with a very simple JE labs design with a single driver and after a few prototypes, I ended up with a 2-way using an Emminence Alpha 15 and a Tang Band W8 2145.

After breaking the DIY speakers in a bit, I was really blown away.  The soundstage was huge and very 3D.  The bass was big and warm but still pretty fast and articulate.  Also, the speed of the speakers was very apparent.  I loved them especially on big orchestral works where the soundstage really comes to life.

I lived with them for about 4 months and then I put the Electrons back.  Very interesting.  Timbrally, the Electrons were just better.  The OBs upper midrange sounded kind of flat and beamy in comparison.  The bass on the Electrons, though not as extended, was better controlled.  In some ways I found the OBs to be more transparent in that they really pointed out the flaws in some recordings.  Well recorded stuff sounded amazing but they gave no love to mediocre recordings.  The Electrons just make everything sound good. Much more forgiving.  

Going from the OBs to the Electrons, I lost some of that soundstage magic.  The Electrons, though they have some depth, lack that completely open 3D thing that the OBs were giving me.  However, from top to bottom, they just sound right.  Instruments sound like how they are supposed to sound.  That all-important midrange really shines.

Though I like both these speakers, I'm going to stick with the Tektons.  However, if what you value is speed, transparency and soundstage over timbre, I think open baffle is a good way to go.  I'll say this with the caveat that I'm not a speaker designer and there may be OB speakers out there that really get the timbre thing right too.  I'd love to hear some!

I had a pair of Alons (partial OB?) with the tweeter and midrange on top of the cabinet that held the woofer in the box and I really liked their openness and non-directionality as I normally sit off to the side and in other seats in an open area that includes the kitchen seating area. Pretty big (about 15x35) with 8 ft ceilings.

After 25 years, it was time for a change and I went with a pair of KEF 500s. Same non-directionality unless I am standing even, in between them changing a record where the Alons still sounded good! Otherwise the KEFs are a better sounding speaker in terms of detail and bass especially, as they are much more current technology. The thinness of the cabinet makes them have that openness and non-directionality so there is not as much reverb within the cabinet, and I put them on top of Symposium Segue platforms (changed out the KEF spikes/discs) which kept the speaker at the exact same height, and they sound even better - more detail and clearer with less internal vibration and isolation from the floor. You can add even more bass putting styrofoam inserts KEF provides into ports on the back of the speakers, but I don't need any more bass. I think for the price of these speakers or their replacement, the R5, you can't come close to the value. Now, part of that is because they are made in China (designed in the UK) which lowers their manufacturing cost significantly. I have to say though that the cabinetry is flawless and looks as high a quality as anything I've seen.

It is not a listening room, and the speakers are very well matched to a Plinius 200 watt AB amp with tons of headroom to spare. If I turn it up past 10:30 or 11:00 it is uncomfortably loud.
