mwhouston Posted November 17, 2019 Author Share Posted November 17, 2019 I have taken a look at the specs. etc. of most of the better single drivers here wondering if we should have picked a better “challenge” driver. The costs blows right out from what I conceived as a simple and cheap fun project. In the end the challenge is still up to make a good looking good sounding pair of speakers out of up the cheap but efficient C2000A driver. A few have said it is quite good, that gives me a little more confidence that the project may produce better results than first thought. My angle of attack is coming from good or different looking speakers and nice sounding. That works for me. I guess “can you make a silk purse out of a sow’s ear”, to quote a phrase? 1 Link to comment Share on other sites More sharing options...

It sounds like a good idea.. a cheap driver makes the competition more accessible and there are plenty of tricks to shape the response of drivers like the the C2000A.. I would be up for it 1 Link to comment Share on other sites More sharing options...

I would be up for it OK that’s two of us. I have to get more low profile trannies from Altronics soon. I’ll pick up the drivers then. I have had box ideas for a fest weeks. Simple and sealed.

Is it the same as Altronics ? https://www.visaton.de/en/products/fullrange-systems/bg-20-8-ohm I have a pair of those, totally different driver and they don't really extend past 10khz. I think the most important thing is high end extension and low cost. An alternative could be something like the oval dual cone speakers they use in the AU-BA falcons, they sound surprisingly good for how cheap and common they are Edited November 17, 2019 by oohms 1 Link to comment Share on other sites More sharing options...

I read that and thought, AU-BA falcons? I haven’t heard of those speakers. Are they some sort of classic diy design that I’m yet to come across? BR is bass reflex, what does BA stand for? I did a google search and all I got was cars and I scrolled down the page looking for speakers and changed it to image search and just more bloody cars. Just page after page of... Ford AU-BA Falcons! ding! Pfft. Brains are stupid. 2 Link to comment Share on other sites More sharing options...

mwhouston Posted November 18, 2019 Author Share Posted November 18, 2019 If anyone in Vic wants the Visaton 8” driver Soundlabs have them for $53 each and they have a few in stock. There is a NSW stocker also. Link to comment Share on other sites More sharing options...

oohms Posted November 18, 2019 Share Posted November 18, 2019 A cheap piezo tweeter could fill that in, but then it would no longer be a single driver unit.. I'll have to get mine out to play with Link to comment Share on other sites More sharing options...

mwhouston Posted November 21, 2019 Author Share Posted November 21, 2019 Really think the Visaton is the way to go. In a 60ltr sealed box appears to have reasonable bass (f3=60hz with resonance extremely low). I would like to try a wide baffle for a change and a switchable BSC network (in or out). The HF side may be a little down but moving away from single drive an external HF driver or super tweeter perched atop would fix that. The Altronics version just doesn’t have enough power handling. BG20-8 does. Inexpensive and sourced in Australia, it would be my choice. BG 20 - 8 Ohm | Visaton WWW.VISATON.DE 20 cm (8") full-range speaker with tweeter dome. High efficiency. Suitable for full-range units as vocal or guitar monitors or as a mid-range unit for full-scale or musicians' PA systems. 1 Link to comment Share on other sites More sharing options...
mwhouston Posted November 22, 2019 Author Share Posted November 22, 2019 (edited) I have stolen this image from the DIY thread. I hope the member is cool with it. This is how I envisage my Visaton 8” single driver build. No port though. I like the idea of a wide baffle board and the tilt back appeals to me. A finished box either just black or a nice timber veneer. BSC at the back with binding posts and make it defeatable. The driver will be centre in the top 1/3rd of the baffle brd. 1/3rd up from the bottom will be a port 3/4” in diameter and the depth of the baffle brd. It will be plugged with a cork from a Woodfords reverse bourbon bottle. Reason is the corks top is made from American oak and when oiled look nice. Pop the cork to change bass characteristics.

planet10 Posted November 22, 2019 Share Posted November 22, 2019 Here is a set of sealed sims for the BG20. A vented box looks to get into the high 20s. My 1st talke would be 100 litres, but it works in 150 litres, and should work in a smaller box with a loss of some LF extension. dave. dave 1 Link to comment Share on other sites More sharing options...

Either one likes the sound or one does not. Amplification matters as well, Room they are put in and so on and so on. At the end of the day one can only give it ones best shot. The design a based mine on is coming from the link above. It is in German however. The other link I forwarded was just for the guys considering a design for the Visaton Driver.
