I've heard some Lowther based speakers that sounded pretty good but some are a little too tilted up for my taste. Weird thing is the good ones aren't all big horns or lines. One was a little bass reflex speaker and that surprised me. Maybe they had a crossover in them to voice them but I didn't think most people with Lowthers did that sort of thing. That brings me to my point. What cabinets work best with Lowthers and do you use electronics for voicing them?

I have heard other low Qts drivers in moderately sized BLH enclosures and they produce a similar performance. They also benefit from a BSC circuit but maybe require a little less correction and are a little more efficient.

My most recent Lowther system is an OB arrangement where I have used 15" high efficiency woofers to produce the bass below 200 Hz and relieve the Lowther of this duty. This has been the best performing of my Lowther systems and has lasted for over years in my listening room. Right now this system is very big, I believe I have found the key for reducing the size to something more reasonable. But I guess technically speaking it does not fall into the catagory of a full range driver system.

If you were at the LSAF last year, you may remember that I was using a computer for my front end. I used WMP as the player. I thought that it sounded pretty good, but a visitor berated me for foisting such lousy sound on an audiophile convention. Well, I've had a year to play with this and I think I have the ultimate answer.

My player is now Foobar2000. The choice of Foobar over WMP is mainly because of Foobar is a much more flexible player. Also the internal equalizer in Foobar has more steps than that in WMP. The final consideration was that Foobar is the only free player that will properly catalog classical music. There are other players around, each with its own set of features, but I doubt that any will sound better than Foobar.

On to filters. I have taken the passive filters out of my speakers. All filtering is now done with the equalizer within Foobar. I simply set the sliders to the mirror image of the speaker's frequency response. Flat response! Adjusting BSC for a different room or position is just a matter of adjusting a few sliders. As a bonus,I've remove the last of the harshness from the Lowther driver. Neat, No?

Come to my room at the LSAF and I'll give you a demonstration.

Another thing to note: no matter what EQ you do, it will casue a drop in efficiency. If you want ultra high eff, then crossing them off in a sealed box or open baffle at 150-200 hz is probably ab etter solution. Of course then you no longer get teh "full range" effect.

So, if you have enough drive voltage and gain there should be no loss of efficiency, no? As for other detriment to musical presentation, I have heard that digital processing may not be as innocuous as first thought... Perhaps if that is the case, it becomes a matter of what matters to the listener?

Just tossing some ill-thought out ideas around...
