Hi guys !

I have built a TABAQ full range speaker which has pretty good bass but I'm planning to play it higher (>80 hz) to increase its SPL. So, I have ordered this Aiyima 3116D2 2.1 amp which has a "100W" sub out (in "BTL mode").

SO, I want to build a cheap Sub and I selected the Pioneer TS-W306R driver because its really cheap.

Here are the specs of that driver.
Resonant frequency Fs 24.6 Hz
Surface area of cone Sd 515.6 cm²
Effective diaphragm diameter Ø 25.6 cm
DC resistance Re 3.6 Ω
Maximum impedance Zmax 46.8 Ω
Mechanical Q Qms 15.60
Electromagnetic Q Qes 0.86
Total Q factor Qts 0.81
Efficiency bandwidth product EBP 28
Compliance equivalent air volume Vas 102.1 liters
Mechanical suspension compliance Cms 270 µm/N
Moving mass Mmd 147.1 g
Moving mass (including airload) Mms 153.9 g
Mechanical resistance Rms 1.53 N·s/m
BL product BL 10.3 T·m
Voice coil inductance Le 1.81 mH
Maximum linear excursion (one way) Xmax 11.7 mm
Peak diaphragm displacement volume Vd 0.6 cm³
Efficiency η₀ 0.17 %

So, for a frequency response of 30 to 80hz and low power output from the amp, which should be my ideal enclosure ?

EDIT:
WinISD is recommending a sealed arrangement. But, sealed means less efficient, right ?
Would it cause any issue with my cheap, low power chi-fi amp ?

Ok, understood.

I have two more questions though 😛

1. Should I get wait till I get the amp to see its cross over point for the sub-out ? (Its a Chinese amp and I'm not trusting their literature saying a variable cross over point option)

2. What about the driver? Is it good enough for good amount of sub-bass ?

1. Crossover frequency seems to be fixed, probably at 100 Hz, which is OK. No need for variable frequency here.
2. For quantity (amount) - yes, it is. For quality - less so. But it is cheap and good value, for sure.

WOW ! Lots of graphs 😀
Thanks for taking your time out modelling the design. But, sorry to say that I'm not knowledgeable enough to understand what your graphs and charts say 😱

So, let me type what I understand from your post.


1. You have modeled the sub in band pass type enclosure.

But, what could be the dimensions ?
I just cannot decipher anything regarding dimensions of the enclosure from that graph.
Can anyone help me ?

2. The ideal cross over point is 154 hz.

Ok, so, I need to set 154hz as the XO in the amp, right ?
The 2.1 amp I bought is still in transit. I'll check it out when I get it.

3. You want me to close the port hole of the TABAQ ?

Look at the second picture in the link. It is the driver frequency response with (bold black line) and without (thin blue line) RLC compensation. The biggest effect is at 3-4 kHz, but it is very broad - from 500 Hz till 10 kHz, to produce rather even and flat frequency response.

Bought the Pioneer 306R subwoofer ! There is no turning back now !
So, can anyone help me to understand Bjorno's post ?
