Default A few questions for a newbie.

Well after much reading and research i have decided to get into the world of speaker building. I have a few questions though and i am sorry if they seem stupid.

I have pretty much decided on the FE206E drivers in a bass reflex design. I decided on this as opposed to horn purley because i do not have the tools availible or the resources ($$$) to build a good horn design.

1. Is the use of a tweeter a good idea with these? On the fostex pdf file for this it shows that a tweeter can be usedhttp://www.madisound.com/pdf/fostexdrivers/FE206E.pdf . The electrical diagram only shows the use of a 1khz capacitator and no crossover circuit joining the postive circuit of the tweeter to the driver. Would this still sound good?

2. I have a new redgum RGi120 amplifier that puts 120ohm @8ohm into each chanel. Will this kill the Fostex Drivers?

3. Any other hints ideas?

Cheers
Warnsey

Hi Warnsey,

I haven't used that driver before so others may be able to help more than I.

1. The use of a tweeter is really up to you. You may wish to purchase the 206E and see if that's enough or if you have to add a tweeter later.

2. What do you mean by a 1kHz capacitor? I noticed on the web page that they recommend a 0.68 to 0.33 mfd. This is using it as a super tweeter. Highest of highs only.

3. The amp will not blow the speakers if you use it wisely. It is safer to use a strong amp and hold back on the volume control than it is to have an under powered amp that you try and squeeze too much out of. Distortion from an overdriven amp can be deadly to a speaker.

I switched from Belle Klipsch to Fostex 206's about a year ago and found them to have plenty of high end, even to my tired iron worker ears. Everyone hears differently though...

I use the fostex 208 sigma BLH with a couple of small changes. They are my first full range driver/BLH's. They had me hooked in the first hour of playing! I'm using e206es-r's in the same horn for the past few weeks.

Thanks for all this help.

I have another silly question. I have read alot about once people finish their speakers and they are not happy with them they add a crossover or correction circuit to smooth out frquency's etc. My question is how do they do this when the box is sealed shut. And yes i am expecting a really obvious duh... answer.

Take the driver out and add it there.

Yes, don't seal your drivers to the box until your are happy. Also, you can do the work outside of the box and install it when complete.

Well since i'm getting so much feedback i mosewell keep on trying my luck. If i'm going to use a bass reflex enclosure for the FE206E is the use of a correction circuit absolutley neccassary or is it only needed if i want better bass response?

Cheers.
