Visaton BG20-8 8" Full-Range Speaker with Whizzer Cone 8 Ohm
Visaton BG20-8 8" Full-Range Speaker with Whizzer Cone 8 Ohm is rated 3.8 out of 5 by 5.
Rated 4 out of 5 by from Successful based on the priceHi everyone,This is the project we have worked very hard to finish. About the end of 9 months, we were able to finish. The reason for this is that in Turkey the carpenter work is very simple, since it is made no one want to do this project. Sequel to a couple of carpenter's fault but the result was successful . Visaton 22BG drive on my project was a result of the successful two-way Passive first-order crossover is used. Visaton the 4200 at a frequency of cut. In the upper frequencies of the Dayton Audio AMT Mini-8 Air Motion Transformer Tweeter used. The cabin's acoustics have paid much attention to. We got a pretty good sequel. Especially Jazz song in the stage environment creates very good. The negative aspects of the product, the view, the sound performance is very low. Front cloth cover if you don't wear an ugly image.

Rated 1 out of 5 by from Does not do anything well.And I should have known better. What is the point of an 8" driver that does not deliver the bass? And there is bad distortion in the highs. So that leaves the midrange which is only so so. I followed the bad advice and put it in a 1.06 cu.ft. enclosure with the recommended port. Even with the zobel and bsc, it still was less than mediocre.

Rated 4 out of 5 by from Nice driver for the moneyThis is a pretty nice driver for the money. It's a bit forward in the mids like many other whizzer cone full rangers and benefits from a zobel network. An 8.2 ohm resistor and a 4.7uF cap is what I used. The top end extension is quite good, but I ended up incorporating it in a 2 way design crossed over at 4KHz and it sounds amazing.

Rated 5 out of 5 by from Fantastic full range for the priceI purchased this just to make a very simple, decent speaker for my office to mate to a Fisher 500C and some vintage sources (Tandberg Reel-Reel, Dual Turntable, as well as my office music server via DAC). I wanted simple setup, no crossovers and basically to "play" with the concept of full-range and see what the fuss was about.I'm a long-time music lover and musician and I remember how good my family console grundig with full range speakers was, so I thought, "why not?" Using the information included on this site regarding the volume necessary, I created basically a mini-tower to reach the 1.06 cubic foot capacity, then did the cutouts on baltic birch plywood, with simple butt joints. I added the parts-express 2.5" tube at the specified 5.75" length, plugged it in, and it sounds far better than a speaker at this price should.So far, on exotica (Arthur Lyman's "Hawaiian Sunset" and Martin Denny's "Quiet Village", both on reel-reel), the sound is excellent: great separation, nice soundstage, far better highs and lows than I would have thought possible at this price. Most surprisingly, the lows are far lower than I thought they would be: the bass reflex design really makes this speaker shine on the low-end.Eugene Ormandy conducting the Philadelphia Orchestra in "Night on Bald Mountain" (also on reel) is also excellently rendered by this speaker. Slightly harsh highs, but we'll see if this gets tamed as the speakers break in (this is written after only about 2 hours of listening time).I have not had a chance to throw some more modern music at them from my music server/DAC, but so far, I am extremely impressed.

Rated 5 out of 5 by from Excellent value and quality fullrangesince its stated parameters are appropriate to a Karlson coupler about the size of the K12, I did some listening with that type cabinet (distributed slit vent). Cone excursion is very low in a Karlson even under bass transients. Midrange was surprising nice on soprano with harp to bass-baritones. I heard some distortion on a cd with sustained synth notes (perhaps not regular modulation "gargle" as cone excursion was less than 1/8" peak to peak) with regular pop genre music it was quite good - no real need for a helper tweeter. although a bit compressed compared to pro-sound, ts nicer than some coaxial/cd on vocals.

How would this speaker sound as a "Communication Speaker"? It would be mounted in a PA Wall Mount box, and driven with about 1-2Watts.

Asked by: Joyfull
This will work very well as a communication speaker.

Sensitivity of recommended ported box

What would the sensitivity rating be for the recommended 1cu ft. ported design? Or more to the point, could a ~5 watt vintage tube amplifier from a console drive them reasonably well?
Asked by: jpl99
Where are you getting a ported recomendation of 1 cu ft? The recomended ported volume is 4.4 cu ft for an F3 of 35hz. The sealed rec is 1.66 cu ft for an f3 of 68hz. I would go with at least 2.5 cu ft NET int vol for an F3 of 47hz.Now can 5 watts drive it? That depends a lot on what you mean by reasonably well. other variables include the size room, distance from the source to your ears, the type of program material and how loud you like it.Also, of what quality is the amp, how fresh are the tubes? Old tube amp manufacfturers {some anyway} didn't play rating games as they do today {2,000,000 watts/ch @ 14%thd @ a 1k sample signal}.What I can tell you is that while 5 watts doesn't sound like much, this speaker is relatively efficient @ 92dB 1w/m. Keep in mind too that a vented enclosure has a +3db advantage over a sealed box below vent tuning freq. as it uses the rear radiation.This driver looks good on paper, got two good reviews and should sound good. You will just have to try it and see. Hope this helps.

i have a pair of these in open baffles and am thinking of adding a tweeter or a super tweeter. any recommendations on tweeter and cap or filter

Asked by: kodo
Basically any tweeter we sell would work wtih this driver assuming it will be crossed about 6-8 kHz. Which tweeter you use is up to you. If you like natural sound, a fabric or soft dome tweeter might be best. If you like a little brighter sound, a metal dome might work better. The tweeter you choose will help determine which crossover you need as well.

just built a pair of winged open baffles with these. thinking of adding another to each cabinet would this be a good idea ?

Asked by: kodo
A little more information, please. What do you have, what have you done, and what are you trying to accomplish? Knowing that will help someone on here to help you. Hope this helps.
