sorry for the late reply, T&t would be a good contender against the crown speaker in a price category, The dual spider system of T&T makes it more durable. But it doesn't mean it sounds better than the other.

good day. i am having a problem with my setup. i am using a preamp equalizer with a mono sub xlr output. using 8ohms tnt sub speakers and 1000w power amp, all xlr output, the performance is ok. i then substitute a 4ohms pyle sub speakers 300w, using a variable 4-8ohms 500w amp, still using xlr output, it seems no sound is coming out of the speaker. however, when i substituted a preamp crossover using rca/pl plugs, it sounded ok.
can you help me identify the problem and solve it?
thank you.

probably cabling issues, balance to unbalance connection since you mention an RCA plug. Please check the connection.

XLR to RCA

Pin

1. Chassis Ground - Shield or outershell
2. Hot - Tip of the RCA Plug
3. Cold - You can terminate it (to ground) with a 10K
resistor if you like or just leave it floating

Talking Question about KONZERT sub-woofer...

Hello everyone...

New member in this website. I just want to ask something. My brother bought 1 pair of KONZERT 8" Professional HI-FI SUB-WOOFER, Dual Impedance:8 ohm . 8 ohm 250 WATTS PEAK 25 OZ MAGNET (KW-880M) from his friend. My question is how to assemble this sub-woofer and what others parts do I need to buy? Do I have to buy capacitor for this sub-woofer? If yes, what value of capacitor will I buy? Any one more thing... at the rear of the speaker it has a 2 pair of terminal. (+ and - ) and another (+ and -). What is the purpose of those 2?

Thanks

Welcome aboard! the two terminals on the back on the subwoofers means that the speaker has a dual voice coil. You can parallel the two voice coil by connecting + to + and - to - giving you a 4 ohm impedance.

Since your subwoofer doesn't come with the a T/S parameters
I will give you a rough estimate of the box/baffles dimensions.

Sealed Enclosure (no port)
height X width X depth = 11inches x 11 inches x 8 inches

Ported Enclosure (bass reflex)
11 inches x 20 inches x 8 inches
with a port diameter of 2.5 inches and length of 11 inches

You can use a PVC pipe for your port/s

You can bent the port tube using an elbow because it will exceed the depth of the box.

Your box will be tuned now around in the 35-40Hz area, good enough for your subwoofers. You can line the internal walls of the box with a 1/2 inch thick foam to serve as a damping materials.

hope this helps.

Best Regards,
audiomachines
