This is my favourit topic: LOUDSPEAKERS.

You can build anything you want (Bipole, Dipole; horn, d'Appolito,
Full range, Electrostatic,...) and if you have done a good job sound
will always be good, even very good.
There's unfortunately no such thing as the perfect thing, there is
no best tweeter or Bass speaker or midrange drivers, there are a
lot of very good ones and we suggest some:

A few tips for DIY: ( general rules , but there are exceptions )
1) Electrostatic pannels and ribbon speakers have low effieciency and are
not " really " suited for tube Single-Ended application.
(Avoid it).
2) D'appolito systems are excellent and will
allways sound good, while they keep a relative high sensibility.
if filtered gently with high quality 6 dB slopes the reward is world class
3) Horns are fantastic, they get the adrenaline flowing, they are in other
words a real pleasure to listen too with any SE amp BUT you need huge
basshorns, excelent midrange horn + drivers and mid high and high
frequency horns, AND a big listening room that is very well damped.
Such a horn system uses minimum a 3 way Xover. (forget 2 way Xovers).
4) Full-range, again for SE this is marvelous and soft/warm sound without
the adrenaline from above. Very good indeed (not suited for high volume
or low bass). ACR offers some good priced models they are my favourites, then you can combine full range with hornloading , and try different speakers .
5) Recommended drivers and filter components:

My favorite speakers :

For tweeters,

Visaton ribbon tweeter RHT 12 and MHT 12 are excellent and on par with the rest (usually more expensive ones)
Thiel & Partner C2 12 is my new favourite tweeter , 179 euro/piece not cheap but better then the rest as far as I am concerned
Scan Speak is almost on par with Thiel & partner and it is rather a matter of taste and finances as Scan speak is more expensive, but is beautifully constructed .However avoid there very expensive ring radiators. Vifa makes an excellent cheap ringradiator the XT-25TG30-04.

Peerless WA10 , cheap high sensitivity and excellent waterfall diagram shows that this is a winner
Visaton TL16H horntweeter for horn systems , is quite remarkable
Visaton DHT9 horntweeter on a budget , almost as good as TL16H at a fraction of the cost
Beyma CP21 or 22 horn tweeters , very cheap and very good and very good looking

Bass-mid range:
the Audax AM130GO is a real jewel but not as good as its predessor HM130GO . There seems to be a new policy at these French companies : The new model must be worse and more expensive !!!!!!!!! ( i go crazy )
Visatons AL130 has remarkable qualities as a bass driver , but if the problems it has are addressed in the midrange then you have 1 of the best here
Thiel C2 95/T6 bass-mid or C2 midranges offer extraordinary qualities at a price , but at this level of performance what does price matter !
Peerless HDS182 is the best buy price wise, its almost on par with Thiel & P.( and i mean ALMOST )
Scan speak 15W and 18W series is also very good , but too expensive , they make excellent units but they want to be the best and are priced as if they where should sensitivity be higher they would move up my preferences.
Audax PR170MO is an excellent midrange, mount it freely , no box and you'll dream away
Fostex Fe208EZ , this new one has such good imaging its unbelievable

For Bass (some of the above are also ok)
Here I'll recommend drivers for sub or 3 way systems
Beyma new 15B100,12B100 & 18LX aquablue, Fs of 18Hz Qts as before and Vas as before.Absolutely amazing better then old JBL and that is a huge compliment.
Peerless XLS10 & 12 are real subwoofer kings at very low prices they are extraordinary specially for home theater.

The new Peerless sub XXLS range is certainly no better, just more commercial.
Peerless CC315 , it looks cheap but it plays excellent , a real tip , its smaller brother the CSX 257 is also highly recommendable.

Wood use MDF its cheap , good and is easy to finish . I have a golden tip for the people who like to try new things ,

use the cheapest plywood ( cardboard used for furniture in 18 or 22 mm ) and brace it enough you'll be delighted !
filters use MKP for tweeter and midrange and MKT for
RC compensating impedance of woofers and mid ranges.
The OFC cable are fine you can experiment with solid core copper.
The filter is very important , use big gauges for the wire that is in the coils of the bass section , use litz tritec or copperfoil for the bass/mid sections

use if you can afford paper in oil caps in the tweeters , avoid 18,24 dB slopes unless you cant do otherwise .

I'll prepare an article covering more theory

Have fun and look at the pricelist Page
