Home Speaker Asylum

General speaker questions for audio and home theater.

RE: How do you feel about adding supertweeters these days?

If the design incorporates a 1" or 3/4" dome tweeter, the thing should get out to at least 18K, which is more than enough for MOST of us at "our" age.

ScanSpeak and other good quality tweeters keep going past 20K too... there should be no reason at all to need a supertweeter.

Now, if you talk about "full-range" drivers and "horn" drivers...

Full-range speakers, especially larger diameter ones, very often roll off too soon for some tastes. So, a supertweeter is added in - usually 5K to 8K, which is very high and too high for the kind of spacing that is usually involved. Same thing with horns - a typical horn has a rolloff rate that is dependent on various physical elements of the compression driver, throat and horn. Very often in PA and home environments these horns have either "constant directivity compensation/equalization" or a supertweeter is added. Again, the physical spacing is generally not recommended at the typical frequencies used for crossover points.

That said, some full range and horn guys think nothing of adding their supertweeters into the mix and do not worry at all about these comb filtering and lobing effects.

Myself, I have no reason for supertweeters for the types of speakers I typically run, which almost always have 1" soft dome or aluminum dome tweeter.

I am really partial to a good quality soft dome...

Subs? That's another matter - and they're not as prohibitive and difficult to add into a system as people think, and very much easier and more practical to add than a supertweeter, from a technical standpoint.

Cheers,
Presto
