Help To Decide Which Aleph To Byilt

[nikosgr]

hi to all

i intent to built an ALEPH, but i cant decide which one to built :ALEPH 2 or ALEPH 4 ?
My speakers have the below characteristics:
1) 6 OHM
2) 92 db/1w/1m
3) rated at about 300w

i have two transformers rated at 1500 VA 235VAC primary 2X43VAC secondary.

Waiting for any suggestions.

6 ohm nominal? More important is what is the minimal impedance and also the phase shifts. Is the 2 not better in driving difficult loads?

i thought so, thats why im doing the aleph2 for my 4 ohm nominal (1 ohm minimum) speakers.

Nelson always says that the Aleph2 is HIS favorite.

With 1 ohm minimum I would make an Aleph 1 or maybe a very high biased Aleph-X.

Or make other speakers

[cowanrg]

well, im doing an aleph2 and aleph3 for each speaker, with active crossovers. so, it should be fine.

they are planars, so they have a pretty easy load, its just low resistance and low efficiency. so they need stable power.

aleph-x's dont work well with my speakers from what i understand. i didnt think they liked low loads. i know they are stable, but i need the power doubling too. to get the power i need, it would be HUGE and heat the house.

Let me guess, Apogee?

[cowanrg]

nope, magnepan.

apogees have nominal impedences of 1 or 2 ohms and can dip into fractions.

Hi nikosgr

I have KEFs 108.2 with 4 ohm nominal impedance and 92dB my Aleph 4s are singing like a birds. Fill free to ask any question as I am more than fine with Aleph 4 (monoblocks)

Here is the link

Hi All

thanks for the replies.

Here is a picture of my living-room that is not acoustically treated
(WAF FACTOR!!!!!!!!!!!!!)35 square meters

the speakers minimum resistance is about 4 OHM

trigon hi
i have seen your work
EXCELENT!!!!!!!!!! AND VERY INSPIRING

my amp is an old musical fidelity P-270/2 it has been upgraded

i believe that constructing an aleph will scale up the sonic performance of my setup

but still i am confused ALEPH 2 or ALEPH 4 they are much alike.
in terms of current output and power which one will have more efficient control over the speakers ??????
