Price drop on the Jamo 210 sub (cheapest price, check Camelx3), and stock is in. Since this is from the UK, voltage is 240V.
I ordered one back in November for £177.85 (~$274) after ordering the Jamo S426 speaker set, and can confirm that it works just fine. Arrived about a week and a half after ordering.

It really depends on the size of the room. Jamo is an excellent brand, and I doubt they would sell a useless sub. The price is good compared to what we would pay here.
You have never heard a pair of MTX Thunder5508 8" subs in full swing, you have to fight the urge to cup your genitals. I have the Jamo and soundwise it is way more than I need, I live in a highrise. its not on Par with my logitech z-5500 as far as rumble but does add lots of low end colour to the rest of my Jamo setup.
It's frequency response starts at 38hz (+-3db), I've owned 12" and 15" subs before and they will happily plumb to 15hz if not lower, which is where a lot of the infrasonics happen (and that people often expect).
I can't speak for your Thunders, having never heard of them, but simple physics limits how much bass 8" drivers can produce.
Speaking of which 200w vs 100w isn't that significant given the relationship between volume and wattage output is logarithmic rather than linear.
Yamaha is 100Watt the Jamo is 200Watt
But the Yamaha is a 10" so likely to have a lower range.
I have had Yamaha speakers before and they are not brilliant bang for your buck
u can bargain them down to $295 for the sub.
I know the jamo is 200w, but im after quality not larger sound
jamo is known as a very good speaker brand in Europe. It's just less known in Australia for some reason.
i think its because we have in house companies like accusound and JMax giving good bang for buck speakers and doesnt need to be shipped all the way from the UK
serious question…what is the difference between 8" to 15" inch drivers? Would the smaller ones have tighter bass? or the bigger the better?! :)
In general again, the inertia of a 15" driver would mean it would be harder to make tighter, however, servo controlled subs can often be pretty impressive. A lot of people struggle to make big subs integrate well with their speakers, for music at least, so often just use a decent pair of floorstanding speakers instead.
It really depends on your usage; do you want to use it for movies and music? Do you want the bass to be super loud and deep? Do you have size limitations (wife imposed or not).
It also depends on your room; multiple subs can often give better bass response if you work at positioning them properly, but there is a lot of acoustical theory to understand.
For movies, to make a true home theater experience, I think you should be looking at a flat response from 20-80hz +-3db (typical LFE crossover frequency). However, the subs capable of that will set you back at least double the amount of this, if not more.
Thanks mate, reason why I asked is because I currently have a 15" sub (dream accoustic), and was wondering if this Jamo sub is an upgrade…
Sorry i neeged you when i meant to positive. Fat fingers on the phone and ob puts the buttons right next to each other :(
smaller ones can have tighter base, but not necessarily so. Larger ones can often go lower, but can be slower due to size (making them less tight). I would not expect a 15" to be very tight; it would need a very powerful amplifier.
You have to consider Size vs Quality of Sound.
a sub box with a 15" speaker is a hell of a lot bigger than one for 8"
Think large coffee table vs small side table for example.
Then there is Price 15" will be a lot more expensive to make and power.
More materials, stronger thick construction weighs a tone, and you need more power to drive 15" eg a larger power amp.
15 will give you low bass… but then you should consider your system.
If you have small speakers then add a 15 sub… you will have a large hole in your sound field. That is why you have speakers of different sizes… small speakers produce high frequencies and the larger the speaker cone the low the frequency it can produce (at the expense of loosing high frequencies)
If you have small speakers in a room with the larger cones are 4-6in then get a 8in sub
If you main speakers have like 6-8in speakers, then go 10-12in sub
personally 15 is just too big
I don't agree with the second half of your post at all; most small speakers should be able to go to 80hz reasonably flat, although admittedly I wouldn't want my sub to have a crossover frequency higher than this (as it makes it much easier to locate the origin of the sound).
A 15" sub is like a Ferrari, most of the time it will never be pushed to it's limits, but can ease along very comfortably. However, when you want to have some fun, or get something demanding, then it can deliver.
For movies, bigger is pretty much always better - more headroom, less effort etc, but the cost and size are the main downsides.
For music, I have a Velodyne DD15, which works in my system, but I can see why people wouldn't have a sub, or would go with something much smaller.
You also have to look into sealed vs ported subs. If you're looking into tight clean bass, get a sealed sub. Ported ones are usually louder but tends to get muddier aswell
so should I upgrade my 15" dream accoustics sub (aka dream hi-fi) to this one?
I mainly watches moves, play games and music (I like my bass :P )
Is the Jamo sub the new crucial M4? Seems like every week it gets posted, regardless that it has been cheaper in the past.
The previous one was from Amazon US, and was 110V only.
Actually, if you'd take a look in my description and in Camelx3, you'll see this is the best price it's ever been.
Amazon page does not quote the power supply requirements:
Product Features and Technical Details
Product Features
This Jamo SUB 210 subwoofer has a 200W amplifier:Auto-on-off.
Technical Details
System Type Bass Reflex
Woofer (mm/in) 230 / 8
Power (W, long/short term) 200
Frequency Range (Hz) 38-200
Much of the audio equipment on Amazon is 110v unfortunately. Also, if you google images of the Jamo sub, you will see most of them show 110V on the back panel (not 110v-240v). It is likely that these are the ones Amazon sells.
I'll be honest, these cheap subwoofers are a bit of a waste of time.. 8" cone isn't going to be able to do much in a decent sized room and won't even get close to reproducing the subsonic bass that most people imagine when buying these things.
In general, they'll struggle to keep up with most movies, and sound bloated and slow with music.. spend an extra couple of hundred bucks on better speakers/amp instead..
