Hi.

Could you please give me some suggestions on which 12-Celestion speaker would add more low-end to the sound of the stock Celestion Seventy 80 in the Marshall DSL 40 combo? Please don´t advise any other brand of speakers, I have to choose a Celestion, as I can have it for a better price....

Thanx in advance for your replies!

G12T-75 certainly has a good bottom end, atleast with my rather bottom heavy Randall. But my experience with speakers is rather limited. But I have heard K-100 is also good in that regard. Anyone?

Yep, I heard some good stuff about exactly these two.... also on the Celestion web they are described as the most bassy.... but the question is: would they sound good in that 1x12 Marshall combo?

Just because I have a good personal contact in one of our local stores and he can give me a big discount, but only on Celestion.... I can have it for wholesale prices, instead of retail price and that´s hell of a difference....

Well what is whole sale price, most Eminence speakers run<$80 each

But yes K-100 and the Classic lead have tons of bass

G12t75 is kind of fizzy sounding with most amps

I also really like the G12h30 speakers for their full bass response

Fair enough. FYI, I got my Swamp Thang for $50. Look into the K-100 if you really want Celestion.

Sorry, I promised my friend not to mention any figures.... but they are even below those 80 USD....

Fizzy? Well that´s not for me, so the K100 and the G12h30 seem to be the best option then....

Don't discount the Classic Lead, it has a modern sound with lots of low-mids

K100 mostlikely has the most low-end, but the high end is not as prominent with it if that is a concern

Also depending on wattage, the g12h75 is a 75 watt G12h30 type speaker. They are bright sounding, but have a big low-end

I´m not worried about less prominent highs, the DSL40 combo has them well in excess.... with the stock Seventy 80 I never set the treble and presence above 2 o clock, because then the high end got really ear-piercing.... so if the K100 takes the highs back a bit, it really looks like my weapon of choice...

....now I discovered a potential problem with the K100 - it comes only in 8 ohm version and the stock speaker in the DSL40 is 16 ohm.... There are also two 8 ohm outputs on the back panel of the combo - is it possible to connect only one 8 ohm speaker to only one of these connectors? And what would the ohmage change do with the output power of the amp? Sorry, these are maybe stupid questions, but I´m really not a technical guru....

yeah out of the ones i've tried the classic lead probably has the most low end (i haven't tried the g12k100, though). it's quite modern-sounding, though, and some people feel it's a bit sterile.

the g12t75 has a lot, too, but it's pretty loose.

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

When you say "fine".... you mean to connect only one 8ohm speaker to only one of the two 8 ohm connectors is technically correct? No risk of damaging the amp?

Yes.

That's exactly what they are for. I note that according to the manual the 8 ohm connections are disabled when the 16 ohm is in use so you won't be able to use your internal 16 and an external 8, but that wasn't what you wanted to do anyway.

You can replace your internal 16 with an 8 and then simply plug it into one of the 8's though.

yes that is correct. remember if you ever do use both 8 ohm jacks you will want 2 16ohm loads, not two 8ohm loads (8ohms+8ohms in parallel is 4ohms, 16ohm+16ohm in parallel is 8ohms)

Yes, that´s exactly my case: changing the impedance of the internal speaker. Thanx for confirming.

Out put is changed based on the speaker's sensitivity rating, not the power handling. Look up the stock speaker's sensitivity rating and compare it to whatever speaker you choose.

The stock Seventy80´s sensitivity is 98 dB, K100 has 99 dB - so the K100 should be slightly louder, at equal amp power, right?

technically, but I doubt you will notice any audibly louder difference. You will notice a difference in the speakers EQ though

^^ yeah. theoretically, at least. 1dB supposedly is barely distinguishable, but the speaker's EQ curve also affects how loud a speaker sounds. A v30 is 100dB, for example, yet most people would say it's louder than a g12h30, which is also theoretically 100dB.

no change at all if the impedances are matched (which sounds like what you're doing).

with valve amps you get maximum power transfer if impedances are matched.

it's solid state amps where impedance can be used to vary the output power (i think, don't quote me on that).

Can you get an extension cab? You're never going to get a lot of low-end out of an open-back 1x12 combo. That's probably the thing that's stopping you from getting good low end. But the G12H (55Hz) has the most lows that Celestion offers.

^ true - but you won't notice much difference if any volume wise.


Edit - I see these guys beat me to it.


Also, remember it will take some time for the speaker to break in so get fussy if it doesn't sound awesome out of the box.

I had each of these in my 212 cab once and I had more low end than I knew what to do with without the sacrifice of the mids and high end.

In the future hopefully I can. But right now an extension cab it´s out of my budget.... the only way I can try to solve it at the moment is changing the speaker.
