Default Low budget project : T-Amp + ???

Hi everybody,

a lurker-become-DIY-first-timer in speaker building, i have a few questions for you "pros" :
i'm waiting for a few T-Amp units to arrive, and would like to prepare their new home so that they'll feel welcome and adopted from the beginning

I searched and read a whole lot on the forum, and already decided to go with the FE207E's in a SINGULAR enclosure. Printed the designs, started to calculate, and went to search for the drivers...only to find out that the cheapest units i could find are priced around 100 euros a piece. I kind of, well, hoped that i could find them for that price a pair, but no go.

So here i am, back in the beginning, except that i've no idea what project to do instead. And here's where i'm asking for your help. What cheaper project could i do for starters ?

Understanding that all this is very subjective, i'll try and give you some information that might help : i will mod the T-Amp (the whole lot - bigger caps, PSU and what-not), so this means the bass will be improved from the stock version. My listening room is rather small, around 6x3,5m. I'm listening to music that's generally asking for bass (but in fact it goes from Tori Amos to Cure to Ultravox to Tangerine Dream to Dead Can Dance to Skinny Puppy to IDM to Ambient to Songs:Ohia, so loads of different stuff except classical --> never, nor techno for that matter. In fact it's either indie electronic or alt rock.)...

Now, for the enclosure : should be discrete. I decided i could live with the size of the SINGULAR, since it's very discrete, but some exotic horns would not cut it (at least for the time being).

I've seen some smaller designs (such as the SOLO 103 ), but have *no idea* as to what they're worth as main speakers...
But it's not mandatory that they'll be *as* small as that. Let's say that anything around SINGULAR-size will do fine.

There, i think i've covered the needs, now i need a solution
Thanks in advance for your help

Seb.

Hey, thanks Scott, that sure looks like a fun project, and fills in what i was looking for...except that i just did some googleing and i can't find the Pioneer drivers anywhere in France. Given the weight and possible taxes when declaring it, i doubt it'll be worth it from abroad

Dang, i didn't think it would be so difficult to find drivers here in france (or in fact you do, but the rather expensive ones). Nothing like RS here...
In fact, i think it'll not be a choice for a given project, but a projet chosen depending on the drivers i can find.

I've seen some VISATON FRS8 for practically nothing, are they worth anything (will have to do some more searching) ? Also, to return to FOSTEX, i've seen the following in the sub-100E/pair range :
- FE103E --> 49E/pcs
- FE107E --> 53E/pcs
- FE127E --> 56E/pcs

Ok so i should have checked my sources before
Jeez, suddenly this doesn't seem too well (even though i know you get nothing for nothing)...

Wow, I haven't listened to Skinny Puppy ( its on vinyl ) in a long time. I went to a show in Ohio where they got arrested for cruelty to animals ( it was a stageprop ). Go figure, its Ohio, lol.

Hi

the Visaton FRS8 is only 82db, I guess that won't work with the T-Amp. You will want something like 90 dB.

Monacor has some pretty okay and cheap fullrangers, the SP155X in about 20-30 Liter BR might be a good bang for the buck in europe, as the Pioneer B20 is just too pricy here.

Or you go with the Beyma 8AG/N horn or "Das Viech", very popular, highly efficient and this animal can play Rock & Roll.

best, LC

I have built the solo103's and although they would shine with the T-amp (I tried it and they did) it would not fulfill your musical needs. The solo is really too subtle and small for rock music. It lacks bass and will not do complex music well. I would recommend the cyburg tangband needle (cheap, fun to build, good quality, reasonable efficiency) or the Fostex FE126/127 in their recommended BLH enclosures. Or you can build yourself something a little more complex but highly praised such as the Buschhorn or newer Frugelhorn. It is not that difficult to make...
All would be happy when driven by the T-amp.
Good luck!

The Monacor SP200X would be a good replacement for the Pioneer too.

Normally, I'd suggest the Monacor SPH-60 in Bigger Is Better horns: www.zillaspeak.com/bib.asp -if you look at the Monacor tag you'll see the dimensions I suggest for this driver: mooch around these pages Dave put together for further build information. Only problem with this one is: a) you need corners to load them right, and b) they might be too tall for your tate. I find them elegant myself, but that's down to personal preference.

Thanks for referencing my Pioneer/Piezo project Scott! It really is a nice sounding speaker… especially for the money. It works perfectly with the SI amp too. It makes me all tingly inside to see how expensive this ‘cheap’ driver is over seas. While it will trounce the smaller full rangers in the bass and has a nice warmth of its own it isn’t the clearest sounding midrange when compared to Fostex and some others.

If warm bass is your priority and mids can be recessed and slightly blurred than the Pioneer B20 is a great driver. If you can add a sub and prefer a clear bright sound look at the Fostex 127e. They also work great with the SI amp! Maybe you can build something like the Omega speakers.

Way to simple! It will be Hi-Fi. The only trick to it is the sweet spot is very sweet and not very big.

That or get what ever is on sale at www.madisound.com for Fostex drivers, they all work.

The Visaton BG20 may be a good project.

Tb W4-1052sa My thread about those TB W4-1052, those are definately worth a try.
