Hi all the names terry,

I currently own 2 RCF 8003 mk2 and i have to say they are an amazing product, ive been eyeing up the thomann subwoofer for a while now and would appriciate any thoughts on it or owners comments.

on paper it would seem that it is slightly louder and has double the wattage of the rcf but i cant help feeling its going to be louder in reality but that is just a hunch.

the buyers reviews on thomann are all in favour and i think its no.2 in the charts for thomann.

but its a long way to ship if its a piece of junk, and doris at the post office will be none to happy when i try to ship this baby back to germany from the uk.

My 2 pennies are this:

We are talking about a Dual 18" sub that should have a theoretical +3db to +6db advantage over a single 18" any day of the week. This means that the T sub is weak sauce in comparison. If you were to add another pair of RCF 8003's ( for a total of 4 ), you would easily have nearly double the output that a pair of the dual 18" T subs could provide.

To make things even more interesting, the Thomann T Sub is a Box store brand. I.E. it is a very cheaply made unit to get it into a market segment that is not actually owned, designed or even produced by the name that is on the box. While Thomann may have given the manufacturer some input as to what they wanted, they had likely nothing to do with the actual making of it other than placing their name on it.

Now for the good side of things. The Thomann T sub is VERY CHEAP!!! So those that will invest in it will get a pretty fair amount of boom for the buck. Because it is so cheap most will afford buying at least a pair if not more. Now, 136db isn't exactly petty change volume. Assuming the speaker at least performs close to the same standard that other vendors do, it will produce decent output. The caveat to that is that most dual 18" designs that are even on teh lower end of the performance scale will produce around 138db. Granted 2db is nothing to really worry about, but it is a clear indication that it is NOT up to the same level as even other affordable units are.

The math side of things. Assuming we can extract 100% of the SPL each speaker says it can make, this means that the RCF speaker is only 1db lower in SPL to that of the T sub with 2 X 18" speakers in it!!! Now if we were to get a full +6db for doubling the number of subs, this would mean that the T sub would have a total potential SPL of 142db ( 136 + 6= 142 ) if you had 2 of them. The RCF would have  141db ( 135 + 6= 141 ) if you had two of them. Now imagine if you had yet another pair of RCF 8003's!?!?! This would mean you have a total of 4 single 18" subs that are capable of producing yet another +6db in output. With 4 of the RCF speakers, you would have a theoretical peak output of 147db! That is 5db more than a pair of T subs and it would still consume the same amount of space. 5db is considerable, but there is more.

RCF is known as a reliable and credible vendor and the specs they state are pretty true and honest. That is to say that the 8003 could actually be capable of producing the peak output it states. Most vendors are not as honest and the peak numbers they state are only capable under very special or specific conditions. The T sub doesn't stand out as being the type that would actually be able to produce the output it states. While 136db is modest for a dual 18" sub, I still don't believe that it will actually produce that number.  Tit for tat right now, I feel that the RCF's would hold their own quite well against the T subs. If I really wanted more boom in teh room, I would double down on the RCF's.

Watts don't make sound.  The loudspeaker rating in Watts is how much power the voice coil can dissipate as heat for a limited amount of time.

If you want more Watts, buy a resistance space heater.

Toasters are also good if you want a lot of watts in a smaller package.

Hot water heater elements are also good for dissipating lots of watts.
