bass speaker help

[lduarte1973]

would be good to have bass/mid/treble control

 

[tinitus]

no, only 2 will work, if you want a smooth control

should be able to do something like this

 

[tinitus]

would be good to have bass/mid/treble control

ups, you are right

I forgot the bass EQ
not sure what will be optimal bass control

 

[tinitus]

not sure what will be optimal bass control

ehh, probably the same again, it would optimally consist of 2 controls, with a mutual centre frequency

 

[tinitus]

ahh, that would be a James Baxandall curcuit, right ?

 

[lduarte1973]

yes , some ibanez basses have 3 freq eq

and a search on John Bingham tone control gave this result

Get one of these.

Despite being made before I was born, there's still plenty of life in there.

Stereo 150w/ch @4ohm (has the voltage swing to do much more - I measured 100V one-way, bridged into 8ohm).

Also has the facility to run with its own active crossover: there's a dial on the back going from 120Hz to 2kHz, and a balance control for between the two. Each channel also has its own FX loop and line out.

I'm running it stereo into my 4x10" cab wired for 2x4ohm.
Effing loud when needed.

Mine cost me £150. There are other models with other features - I've seen basic 100-150w ones go for <£100 on eBay.
But yeah, tonnes of headroom, lots of facility for shaping your sound, and very cheap for what they are.

hey, Chis, that one looks great

well, Im heading towards a single band parametric with a Bingham tilt control

but how to is the bigger problem

 

[tinitus]

would be good to have bass/mid/treble control

hey, you may be right about it

looking at stereo unit, and hope to change to using 6 mono controls instead
might be nice being able to switch fast between 2 different settings
and even further, the two 'channels' could also be configured slightly different
that would be for the mid only

woofer might have a simple 2hannel parametric

 

[lduarte1973]

what amp are you using ?

 

[tinitus]

older LC Audio stereo amp
I built it 15 years ago for a teen famely member
now got it back
for once I love low WAF factor

 

[lduarte1973]

where´s the tube preamp stage ? i dont like only ss for bass or guitar amp

 

[tinitus]

i dont like only ss for bass or guitar amp

probably because you have only tried the cheap ones

solidly built SS power amps are expencive

 

[lduarte1973]

you might be right about that , but i´d still try it with a tube pre you might prefer it´s tone

i saw your ss amp looks like a good build

 

[tinitus]

....but i´d still try it with a tube pre you might prefer it´s tone

its coming its coming

waiting for tubes from siberia
seems like they dont ship from there every day

14 days since payment, and still no sign of being shipped

 

[tinitus]

waiting for tubes from siberia
seems like they dont ship from there every day

and the tubes arrived at my doorstep just now

 

[lduarte1973]

now you have no more excuses to build the tube preamp

 

[AndrewT]

From 2350hrs yesterda, when it was not yet shipped, to 0918hrs today when it was on the doorstep.

Concorde lives !
