sub help needed
which sub will work well with a budget sound bar, i bought the Yamaha YAS107. It is to replace my big 5.1 yamaha system . todays values ive replaced a $2500 system with a $200 system. i dont expect much but i am pleasantly surprised so far how well it works. I am using my original and old sub which is a 10'' polk, cheapest one.. The sound bar has a phono/rca sub out and that is why i chose it. It sounds ok for the money. but the sub works better when its hooked up to the speaker out of the receiver. even the sub user manual said best results are from connecting the speaker out of the amp. i have to use the rca inputs on the sub with the sound bar. Ive found the bass to be ...and i dont know tec audio file terms. not low enough, no real rumbling of the floor, windows, cannot feel the bass. its loud enough but is boomy and not clear and muddy. Its an old sub, could be faulty too, it did cut out once a year ago, no bass at all, but it came back but has never been the same even with the big 5.1 system. time for a new sub.. so if i were to replace it with another budget sub, considering i want home theater style of bass and im not too far from that all ready. What sub should i buy? i like to tinker so im ok with adjusting and setting up LPF and gains if the controls are available.
