Celestion Pulse XL 10.40 Cab

[LeighOnSea]

All done!

Sounds much brighter and L-pad dials it up and down, but not hugely.

I had to be inventive with the tweeter fixing but its OK

Now deciding whether to put on Marshall handle or not

I put in the 2 uF capacitor.
What would happen in terms of sound if I changed to the 3 uF? I am guessing slightly lower frequencies will get through to the tweeter, but am not sure if that will brighten the sound or do nothing or something else.

Its great, thanks very much indeed for all your help!

Try it

 

[LeighOnSea]

Try it

I was trying to avoid that as I wouldnt be able to compare the two side by side without some sort of temporary switching circuit.

However, I have now rigged my cab up as a sub woofer to our stereo with a dual RCA to mono 6.5 jack plug, and now its obvious that the L-Pad is actually making a huge difference when dialled from hi to lo

 

[agedhorse]

You really have to try it because your personal tastes can’t be accounted for in a recommendation.

 

[6thplanet]

Agree, try it. Honestly it will probably be subtle. Worst case, there's not much difference and ya just leave that one in there.
Looks great!

 

[LeighOnSea]

I changed the 2 uF cap for the 3 uF one

It was quite a subtle difference but a good one that I could most easily hear whilst using the cab as central box on my stereo.

It clarified the sound, made all the instruments more easily distinguishable and made the bass less wooly

Now, the nicest sound to my ear is with the L-pad just under 12 O'Clock 'normal' (~ 11 O'Clock) rather than before with the 2 uF cap at just after 'normal (~ 1 O'Clock)

With my Sire Markus Miller V3 bass and using the Markbass combo amp (with Markbass drivers turned off) its great, and gives a sound with more clarity in passive mode than active mode.

The Markbass is definitely nicer but not by an order of magnitude at all, so I am quite pleased with my first effort - a very satisfying and interesting project

My Bass player mate was here on hols, and he liked it - he will donate me a tube bass head to use with it, that I will pick up when I'm back in Blighty next

Thanks very much for everyone's help!

Now its time to practice

 

[6thplanet]

Sounds like a win win situation.

 

[LeighOnSea]

oh, and I realised why the L-pad was much bigger than I was expecting - I mistakenly ordered the 100 W version instead of the 50 W one (I just picked the most expensive one as they were only €4 different and didnt notice the wattage

 

[agedhorse]

100 W L-Pad is fine

 

[LeighOnSea]

Final touches done.
I couldn't source black screws easily here in Portugal, so a quick search gave a tip from a woodworking forum that looked so easy I had to try it, and I'm happy with the results (and even if it scratches off a bit, its easy to touch up):

A question about using my Cab as a central box on the 'B' speakers of my Stereo's amp:
Both woofer and tweeter are 8 ohms but I am using a cable that combines both Left and Right RCA outputs from the amp to a single Mono 6.3 jack into the cab.
However, since the amp says 'Speakers 4 - 16 Ohm' I think this is fine, is that correct?

Also, out of interest, with this setup what is the 'effective' impedance of my cab connected like this compared to that of two (Left + right) 8 ohm speakers?

Cheers

 

[6thplanet]

Not quite sure I understand what your doing. Amplifier outputs are rarely RCA type connectors. If it is, I don't recommend using the cable you stated your using.

Your cab should be a nominally 8 ohm load.

Hi, when I said Stereo's amplifier', I meant the amp of my 'music Centre' , 'HiFi', 'Stereo' etc etc, whatever is the correct term in different countries and age brackets

Like this:
(The 'amp' is the silver fronted box (A Pioneer from the 70's) to the right of the turntable, under the laptop)
I am also connecting my cab to this music centre on the second speaker circuit of the amp that has red and white RCA connector outputs for the speakers (which is my Father-in-laws own modification I think)
Anyway, I am connecting my mono cab to BOTH the speaker outputs, left and right via the lead I have to send both L & R channels to it
Sorry for any confusion

Right, well from that explanation, you should still not do that. You can't just connect two outputs together as you described. This usually ends up bad, as your shorting the two outputs together. Amplifiers that are bridgeable have a certain way they are connected to have the two channels work together.

Hopefully no damages have occurred.

Thanks!
Well, the Amp was smelling a bit warm, but it all still works, as does the cab
BUT, I will stop doing that, right now
A pity as it really improved the sound of the stereo.
I could still use it on one channel only, but then it will only play one side, unless I switch it to mono and then the floor speakers on 'A' wont be in stereo

EDIT: Maybe something like this?

[agedhorse]

Don’t do this unless you want to destroy your amp. RCA speaker jacks were used by some low end models for convenience but caused more problems than they solved.

 

[Tassieviking]

I did notice in WinISD that I could put the speaker parameters in myself

I usually find the drivers for winisd on loudspeakerdatabase.com

Just download and place them in the driver folder where winisd is installed.

I was trying to avoid that as I wouldnt be able to compare the two side by side without some sort of temporary switching circuit.

Why not put a switch in so you can add more capacitance ?
A few switches next to the L-pad wont look too bad, 1uF, 2uF,3uF, 3+1=4uF, 3+2=5uF, etc.

Nice little home build, well done.

Absolutely no. Your missing the point that most amplifiers/receivers don't use RCAs for speaker outputs. So looking at things like that, that use RCA connectors, are for preamp level voltages.

Forgot trying to run that cab off of that stereo, you got lucky it didn't toast it.

To get what your after it's gonna take a lot more that just hooking up a cable.
