Hi everybody,
Have been lurking for quite a while after discovering this great world of DIY. Hope I commit no forum taboo; please let me know (kindly) if I do.
Am interested in a first time simple design for full range driver. From the posts a Voigt pipe with a fostex driver (FE167 or 206E) seems a good way to go. Have a couple basic questions.
1. I don't have a tube amp--have a 110W/channel solid state home theater receiver. The fostex are efficient. Is this too much wattage? What is a good reference on tube amps?
2. What is the most straight forward plan to follow for building a voigt that you"ve seen a link for? What happens if you substitute a different fostex driver--what parameters do you check?
3. Have seen baffle circuit schematics but what reference do you recommend to see the actual construction (I'm telling you I'm a novice and may need a good starter book on electronics!).
Any help is, of course, greatly appreciated. Look forward to lurking, learning and eventually contributing if I'm lucky. |

Full range drivers work great with SS amps with some power. The power provides a significant amount of flexibility in the BSC filter design. I have been using a 200 W SS amp for years and never had a problem. Right now I am driving my Lowther ML TL design with a TEAC A-L700P chip amp ($95 on Amazon). A tube amp is definitely not a requirement for a high performance full range driver system.

There are two designs on my site for the Fostex drivers. The ML TQWT, project #2, will use the FE-167E driver without modification to the enclosure or the filter. The ML TL design shown in project #5 uses the FE-206E or FE-207E. If you go to my gallery you can see pictures of these designs that other people have made. The builders can be e-mailed directly to ask questions and gather opinions. Bob Brines also offers an excellent design for the FE-167E, his site is linked from mine.

If you look at my Projects #4 and #5 you will find pictures of typical BSC circuits. In my "General Speaker Related Articles" link there are a couple of documents describing some of the BSC options and methods for sizing. The variable BSC is a great way of adjusting on the fly and getting the most out of the circuit.
Hope that helps, |

Appreciate the prompt response to my questions from Martin and Jens. Great to hear that I can use SS with full range drivers. I will follow up once I "study" a bit more on the designs. Looking forward to diving into the actual project once my plan is set. Thanks again
