Subwoofer with 206esr

[Pendergast]

Hello,

I am a happy owner of a S.E.X. from Bottlehead (single ended, about 4 watts per channel) hooked to a nice pair of Fostex 206 esr.

I want to upgrade this however; I had a friend come over with a subwoofer, and we experimented over 5 hours with various music. Clearly, I could get some deeper bass.

My music styles are varied, and I do have a weakness for 50's and 60's recordings, or acoustic instruments.

So I am looking for 3 tube monoblocks: 2 for each 206esr, and one for a subwoofer (maybe some dynakits?). I am thinking of the Table Tuba of Bill Fitzmaurice, and some very efficient driver.

Any comments,? Suggestions?

By the way, I am into DIY, so the monoblocks and the subwoofer, I will do myself. I am "intermediate" so I am looking for some challenge, as well as your suggestions.

Looking forward for your advice,

P.

Hello,

you don´t need a sub with the SAXOPHON,
or you try something like that in bass:
ALPHORN or cornerhorn,

hm,

Nice jobs!

However, I really want a subwoofer, as the main speakers are here to stay.

Hello,

therefore the 2 x ALPHORN beside your horns would
be useful, aktiv cut ~ 60 Hz

I went the same route as you may go. I started with a Fostex 208EZ on an open baffle. Then, dissatisfied with the non existent bass, i added a sub and the sound improved alot. Then i figured, a tweeter could also help. After this, i realized, that a well implemented 3 or 4 way system is the way to go for great sound, which is what i use now, the Fostex sold well on ebay

For great subs, look into tapped horns, as they are very efficient and small compared to a fullsized horn (but still bigger as the extremely compromised horns of the poster above). Volvotreter has made a nice and small design, maybe look at his homepage for more information.

Nice suggestions !

Any idea for drivers? I am looking for high efficiency.

Have a look at this page: http://www.volvotreter.de/th.htm

There is one big eminence and one small tangband taped horn. You could simply build one of these or visit the tapped horn thread, read it (its long) and design your own.

Or have a look at the homepage of the inventor of this horntype: http://www.danleysoundlabs.com/

Have fun

Drivers?

I would take for a bass horn like the alphorn,
with active sub modul up to 100 Hz:

specially the BL is for me important in comparison with
a 8" FR, the moving mass must be small, thats why i use max. 6.5"

As a proud owner, I'm a huge fan of Rythmik Audio. I've never heard a better subwoofer. Build the sealed version and enjoy amazing bass.

Owner/designer Brian Ding is a pleasure to work with as well.
