"Slam"--what is it, is it really accurate?

After I recently was at another audiogoner's house and saw him working with his banana connections in his setup, I decided to take a look at the bananas on my low frequency run. What I did was to pull a bit more of the cable through the connector and fold the entire cable over on one side of the connector.

What this resulted in was that upon screwing the banana ends back down, it was a much tighter connection and much harder to screw them all the way down. I did this at both the amp and speaker ends of the cables.

Lo and behold, after this free tweak, there is clearly more impactful bass attack. Should have done this years ago!

Now, I just purchased a much more powerful amp, Krell FPB400cx, which should arrive next week. I will be interested to see if the introduction of the Krell will provide an additional incremental increase in bass slam, weight, and control over my current McCormack amp.

MT,

Just wanted to point out that the very act of reattaching the wires alone could result in a better connection than prior, though the folding part probably can't hurt.

@ Mapman,

Yes, while I was at it, I re-tightened the high frequency cable connections. My high frequency cables are Morrow SP2 with the nude termination. My amp terminals have a hexagonal segment, so this time I used a wrench to tighten down the connections at the amp tighter than I previously had done by hand. I also tried to really tighten down the connections on the speaker as well. I do believe this significantly improved my highs and mids.

slam is amp power + speaker effecience and it must be on the recording. when its right, you feel it viscerally.

Mtrot-

I have never liked the term 'slam'. I always equate it to SPL (a better term). It all relates to the size of speakers in a given room. One would not want under-sized speakers in a large, ex-large, listening space.

I concur that the power amp plays it part as well.
Happy Listening!
