Any cables that give more bass

Why would a ps audio dliii improve the bass response of his KEF's that only go down to 55hz????? Why would Analysis Plus Oval 9's improve bass response that the speakers can't produce (flatly at any volumne)?

If the OP wants to hear punchy bass, the bass line, low organ notes or the tank rumbling into town in Saving Private Ryan...the OP needs a sub-woofer.

Low organ (or piano) notes yes but bass is still within speaker's response (lowest bass note E=44Hz). Analysis Plus Oval 9 are a little bass heavy. Moving speakers and listening position toward opposite walls will help as well.

The OP already got what he wanted by moving his speakers 7" nearer to the wall, if some of you still have not noticed. Anyway I generally agree about the subwoofer improving the bass in a significant way. Not to say cables won't affect bass but the level of improvements compared to a subwoofer is marginal. The OP's room is only 10'x11' so he might still get away with a subwoofer by playing around with speaker placement. Bass traps will only improve bass definition and focus by reducing boom and loose bass and won't make the bass more punchy. It's surprising that the speakers can only go down to 55Hz±3dB with the 6.5" woofers though. I have speakers with 4" and 5" drivers and they all go down to 35Hz, but I still use a subwoofer with them in a 11'x17' room. Ironically the speaker with the 4" woofer goes down lower than the speaker with the 5" woofer due to the TL design and larger box enclosure.

thanks for all ur opinion &advise!
