Default Horny valve virgin comes of age..

Hi all. I am as you can see new here, so go easy!
I recently bought on a whim a pair of small rear horn loaded FE103E's , small being a standmount, I have not seen the like anywhere else. Later that same week, I bought from a freind an Icon Audio MC34 integrated valve amp and my life has changed since then

I have never heard such clarity in recordings before, and though the treble and bass are somewhat curtailed (actually, the treble is great really, it is just the bass that is a little conspicuous by it's absence....) the other night it felt like I had the Be Good Tanyas right there in front of me....you get the picture.



Anyway, the upshot is that now I am itching to try a bigger design to get a bit more fulness to the sound. I have looked a couple, including Fostex's own designs, and some produced by the talented people on this forum.

So, the question is, do I keep the 103's and build a bigger cabinet, if so which is "best", or do I go for some bigger drivers in a bigger cabinet? I have to say though that whatever road I take I do not want to lose that incredible midrange, or the imaging..

Any suggestions greatly recieved!

Thanks, Steve.

Fostex' 103 is a very well built unit, and even more interesting, it can be obtained new for under 75 Euros a pair.

I have experimented with the Nagaoka Horn for the FE103E, this horn is approx 80 cm high so no real pain in WAF

I can try and fix you the drawings. The cabinet is too cheap so since you allready got the drivers

Hi Merijn, where have I seen the name before.....? They look great, WAF is not a problem, so really any design would be OK, though personally I could not live with for example the "swan"

I have seen a lovely looking design on a site from one of the members here, it is a dual horn, not sure if it is suitable for the 103 though, this is why I was wondering should I go for some larger drivers, I wouldn't mind so long as I don't lose that lovely midrange.

Plans are here:

BK-101? These have been my workshop speakers for 10 years.

From my experiemce i'd recommend not doing the Fostex recommended horn.

Hi planet10, they do look a bit similar to the ones I have. I have already had a look at your site, and used the inks to the "spawn" family of encloseures that I like the look of, not least because some of them look relativly easy to build. What would you recommend? Do I stick with the 103's? or go for a bigger driver in one of those lovely spawn cabinets?

I have built several variations of DIY cabinets using fullrange. I am in the middle of completing Suzy Chang (one of the spawns, custom designed for FE107E) (similar to FE103 but shielded). These cabinets in particular optimize bass without losing the highs and I assume mids.

There is no reason not to build spawns in my humble opinion. I also liked BIBs but spawns are nearly as easy to build and I like the style better.

Using the 103s would mean leaving your BK101 driverless... but i suspect that they would go into Suzy Chang. Might also work in Aiko.

Bigger drivers give more bass (but if you go bigger than FE126/127 you start sacrificing midrange quality.

Questions you have to ask are room size, budget, amplifiers
