Thanks

As that thread showed, there are several options, hopefully one of them worked for you.

I connected it using the speaker output of amplifier and connect them to the speaker level input of sub and from sub to my speakers (Acoustic Research M4). Too much boom, boom and I prefer the sound from the amp to the speakers directly. Tested it on Saturday and sold the sub today. Thanks for help

Could have been the sub, no way to tell for sure.
If that is the whole sub plate you posted, I don't see a control for crossover frequency. I don't see a low pass switch either. Those may have given you the ability to make the sub more pleasing to your ears.
Just guessing, your only options were to use the sub volume, and the Luxman bass/loudness (if equipped) which would have affected the bass of your main speakers.
A newer receiver/amp might have a function to set the cut off frequency going to a sub.
That sub did have a phase switch, it should be fairly noticeable when changing from 0 to 180.

Maybe, if you get the chance, try another sub. If you could borrow one that would be best since you already tried one and didn't like it not sure I'd recommend spending money on another one.

No goodolpg will not use another sub. May be I will buy another pair of speakers but will not be able to get the same model of speakers i am using now, will have to buy a pair of speakers of another brand and hope that it will match (but i know that it will be difficult). Thanks for your help

That is NOT a proper subwoofer to base any opinion on, it was part of a sub/sat system with specific cutoff frequencies.
Without the ability to adjust the upper operating point of the sub to MATCH your speakers, it would be a lot like having vastly different left and right speakers and still expecting good sound.
