I also have to admit that I have a dislike for 18" drivers.



The SWR Big Ben is a great 118 cab -- quick and full range IME on the store floor. Always kind of wanted one. The older ones came with a Bag End driver.
Probably related to my now having found my bass tone happy place with two Bag End 115's
Does a 1x15 have any advantage over a 1x18?
It depends on who is carrying it.
The practical problem with using magnesium (aside from fire if the coil becomes intermittent or burns open) is ...
Ugh, 1X18. It looks so good on paper...
Yes, you are MUCH better off with a 2X15, or even a 2X12. Your gut tells you so. Listen.
My 1X15 driven by around 350 SS watts at 8 ohms can pin my loud azz drummer's ears back.
Around 400-500 SS watts 2X15 4 ohms can absolutely own a large theater or outdoor stage.
How much volume do you need, mate?
I use a 4x10 stacked on a 1x18 currently. Recently I plugged into a friends 2x15 and thought it sounded incredible. This has me really eyeing a 1x15 to replace my 1x18 in my rig.
Is there any advantage the 1x15 would have over a 1x18?
Absolutely not picking on @dbsfgyd1 This comparison of NOMINAL hole size (i.e. the speaker size, 10", 15" 18") has been brought up many times in this thread regarding things like how much air can be moved, cone area, etc. and concluding one will have more output than the other.
Pages back I suggested the THREE DIMENSIONAL cone cannot be calculated by its diameter. You have to find the cone area on a spec sheet and multiply that by Xmax to compare. @Rick James later posted the same (or similar) with better terminology... displacement.
I suggest those seeking to compare speakers ability to "move air" look up ten speakers of their choice size on Eminence Speaker | Loudspeakers for Professional Audio and Guitar and Bass | The most trusted name in loudspeakers since 1966. Great upgrades for JBL, Celestion, Jensen, and Fane. or eminence speakers on parts express if you prefer. Check both the pro audio and bass class. Look at the specs and compare the displacement to the OP's 18. I love 15's and can't tell you exactly why. But those suggesting a 15 or 2 x 15 will kill his 18 based on nominal hole size might be surprised to find some 15's can have just over half the displacement of the OP's 18 (very little gain in a 2 x 15 as far as displacement), yet others may have more displacement, so even a single 15 to could gain some ground.
While you have the spec sheets up, also look at the mounting parameters and not the baffle hole size requirement. Even if the cones were flat, not cones, disks in fact, they can't be larger than the actual hole size, which can be quite a bit smaller than the nominal.
Of course there are so many other factors, some published and some not, some subjective and some not. If you look at the spec sheet and don't know what the parameters are, I think it would be best to learn those and their effects before making blanket statements about a certain size speaker will move more air. I'm not married to a speaker size. After a 12" open back geetar speaker project for my wife, my next bass project is a pair or two of neo 8's.
Duke LeJune built a TC-118 and a TC-115. He's currently redesigning the 118.
I didn't feel like looking back for specific posts making claims on "pushing air" vs. diameter, so posting right after your post I thought might come off wrongI don't mind being picked on if I'm full of gas. I should have been clearer on what I posted. What I should have said was it might not have been the diameter of the speakers that made the difference, but the combination of the design of the speaker and cabs. I'll still stand on my Eden 10s (probably made by Eminence) having a tighter more responsive bottom end than your fifteens, or any 18 on the market regardless of cabs, however.
If I wanted to make a stand-alone 18" cab, that's exactly what I would do. Probably with an L pad for the mid(s). But I like a darker sound. It will be very cool to see where the @dukeorock 18 goes!Dukeorock is doing a sealed-box 118 with dome mids that looks pretty sweet.
Sorry to hear the parts situation is harassing your 18" cabs Duke!

I'd love to hear one of Dukes 18 based cabs some day.
With a little luck, I'll have one at the Invalid Link Removed in about three weeks. Wish you could be there!
