Default Pioneer B20 and Visaton BG20

are either of these cheap fullrangers any good.

thinking of having 2 or 4 in ob with a super tweeter. crazy idea?

cant afford the B200 at the moment, i allready have some CSS Fr125S's in IB which are ok, but looking for a floorstander using fullrangers, and at least 8 inchers as i listen to alot of rock lol

a real ultimate budget speaker

(or do somthing like this.... http://www.zillaspeak.com/pioneerb20-piezo.asp)

inrank,

My pioneers are my main speaker. I love them. You can check them out on my website. My box is a bit different fron Godzillas, but I really like these drivers. I have a pair of wr125s, but they have been moved to make space for the B20s. Here is my thread about the pioneers. Infact I just added BSC today when I dropped by a local audio shop.

I have also heard good things about the BG20s and would recomend them as well. The BG20 has lower Fs, high efficency, and greater xmax.

Good luck,

Josh

Josh those look really great!

I enjoy my B20's at work every day. They are kind of like an innexpensive car that performs very well... and if it can't go 0-60 in 6 seconds flat it's ok because it's still fun. I don't even mind if the boxes get dings in them.

I was just looking at the Pioneer FR in box plot and interestingly enough it looks like it might make a nice little sub. Not a lot of Xmax but but can be tuned for nice extended low bass in a reasonably sized box. As an inexpensive option for a bedroom system who knows.

Greets!

OK, have you made a formal request on the BIB thread?

Anyway, not true, scroll down for the B200: http://www.zillaspeak.com/bib-gm.asp I'm not sure why any BIB designs I've had input on is listed separate.

Hi GM!
My original intention was to disperse them throughout the thread but it was easier to put them on one page. I will put them in their appropriate places in the coming days.

Pioneer has another 8” driver that looks similar to the B20 without the wizzer cone.

Peace,

Greets!

Cool! Thanks for the effort!

FYI, the ~5 yr. old pair I have are strictly midbass units and better suited to small lead guitar practice amps since they begin distorting like right now, so for HI-FI I recommend either sealed or aperiodic with a separate sub system, though if driven with an impedance matching amp, a Vb = Vas, Fb = ~1.62*Fs 'vintage' vented alignment should work.

That said, I mass loaded one with poster tack to both lower Fs/raise Qts and damp down its HF BW (covered the DC and filled in the hollow where it joins the diaphragm) and it shifted the distortion to below my acute hearing BW enough to use it as a LF 'fill' driver for the modest SPL B20 OB prototype I posted about on the original FR forum.

As always, YMMV.

GM
