Perfect low/sub for the Turbosound TXD-081

As a general rule, the fs should be close to what you expect the tuning frequency of the box would be.  However there are lots of drivers with an fs in the 35-40Hz region so that doesn't narrow it down much.

One to consider might be the 18Sound 15LW1401, they sound very nice.  In terms of finding one which will be a bit faster and play up to the 8" mid-top well, look at the mms and choose one which is lighter if possible.

What you might tend to find is the lighter drivers with stronger motors might look a little lacking in the bottom of the range however this can be corrected with a little EQ as most decent drivers will have sufficient excursion and power handling for this not to be a problem.

I don't think so.  18" reflex is a good option and will easily meet your MTs but maybe you want a weak little bass sound

Hello everybody,

What do you guys think of this woofer for my applications:

Relax, I was just teasing because you rejected my suggestion so readiliy.  What I'm saying is that all 18" designs I've seen will play high enough to meet your MTs but if you want to cross the TXDs over as high as 250 Hz, then that's up to you.  IIRC, the recommended sub for those is an 18" reflex that only goes up to 150 Hz or so.  A 15" or 12" can be tuned low enough but if you can cope with a larger box why not?  Reflex are an easy build and won't need time alignment. You don't say how you'll use the system or what kind of music it'll be used for but the combination of an 8+1 on top of an 18 or 15" reflex is a proven design for a small portable system. S

Excuse me, because my English isn't quite a 100% I don't understand everythinh the way that I wish to.

I don't want to cross my MH's to 250 hz. I usually run them from 120-150 hertz or alike and up.

The system will be mostly used inside. For simple playing music. All kind of styles.
I also have 4 or 5 times a year an outside event for this system.
The audience won't be larger then, well, 50 to 60 people MAX.

Thanks for your reaction!

I have a new question. I just found these designs:

Is it possible to find a woofer that fits in one of these designs?
So, turn the whole thing around, find a suitable driver for a design. Not a suitable design to a driver. Haha

If I could build one of these... well, that would be perfect!

So, it's been a while!
I've used a 10" frontloaded sub, a 15" bandpass and even an 18" subwoofer along these Turbo's.

And since a month or so I use an slightly modified 'PAL12' tapped horn. The speaker I used is a Ciare 12.00SW, wich has been collecting dust on a shelf for way too long.
It al began with this:


Despite some errors caused by my CNC-cutter, the sub fitted nicely.


The rabbit seemed to agree




Here it is, all glue'ed up and ready for some serious sanding&filling


I decided to use the reflector panel, where normally the wheels are placed, as an connector panel.


As you can see, the connector panel is recessed in to the cabinet, so placing it closely against a wall is possible.


After the filler I applied a layer of primer (just to be sure...).


The paint itself is Trimite J136, instead of the more obvious choice Warnex. I was able to buy these for a real bargain price


I am really happy with the finish. I applied it with a structure roller (don't know if that is the correct name sorry).


The connector panel again


Ta-daa


And of course I added my own little touch to it...


And here it is 'at home'


And yes the Ciare woofer is 'visually well used'.

First listening impressions are definitely positive. This thing really performs in the sub-low regions; I have not been able to find a song which included a lower note then this sub can handle. It easily pushes hard in the 30-35 Hz region, 30 Hz just as easy as 40- or 50 Hz. A pretty incredible experience at the SPL this sub can reach, to say the least.

I do notice that this design has some difficulties producing the more higher regions of bass, for example the ‘hmmm’ or the ‘humming’ sound, also known as kick-bass (the bass that really hits you). Very prominent in nineties electronical music. I suspect it being the 70-120 Hz region. Nevertheless this sub is very musical, you can hear the different pitches/levels/stages in the bass. For that matter this sub passed all my demands, the ‘one-note bass’ I often hear on the larger festivals (in NL) really irritates me. The the higher regions in bass are just less prominent with this design.

Concluding; I highly recommend this design to everyone that is looking for a relatively compact (it is NOT small) subwoofer that can easily reach 30 Hz, and is planning to use them either with a dedicated kickbass cabinet or a ‘hefty’ full range speaker.
Oh, by the way, I power this sub with a bridged QSC PLX1602. The TXD-081's are also powered by a PLX1602, but then obviously in stereo. These speakers will soon be replaced by something that DOES produce the high-bass to accompany this sub. The PLX’s will be replaced as well, by a 4-channel lightweight.

And yeah yeah, a decent 19" rack is also on the to-do list
