(1) I didn't say totally transparent, I said "more distortion" and "more
distortion free".

Two amplifiers, driven by an electronic crosover, are even more
distortion free yet. :-)


(2) At this point there is no formal definition of "low-priced"


How about under $200?


Buying twice or three times as many power amps pretty well creams a $800
system budget. Interestingly enough, a $800 system based on better quality
parts from the PC monitor or One Box Home Theater market segment would
probably end up with an active crossover.

Please see my 7/16 post about subwoofers.


Staying within an $800 budget is not tough.

Two, low cost, sterio amplifiers: $400
Passive electronic crossover: $ 20
Two Vifa woofers at $100 each: $200
Two Vifa TG 27 tweeters at $30 each: $ 60
Two old enclosures from a garage sale: $ 20

Total: $ 700


Well, at the cost of the extra amplifiers, which in a $800 total system cost
for a system assembled by a consumer, makes things pretty tough.




3) Pick a woofer that is designed to work into a closed box. (Avoid
buying woofers that need to work into ported enclosures.)

????

Because making a ported enclosure work right, is more difficult than
just sticking a closed box driver, in the proper box.


Most manufacturers of quality woofers provide T/S parameters and leave the
design up to the purchaser.


Manufactures give a "VB ltrs" spec. Isn't that the recommended box
volume?


Zoebels are for people who don't get it.

I'm one who doesn't "get it".

Zoebel networks convert the driver terminal impedance to a resistance.
That improves the crossover's rolloff characteristics. Zoebel's are
simple, cheap, and work darn well.


The price/performance and time investment is hard to beat.

Investing time, saves money.
