| Why are my woofers pumping? Ct0517 you are right - i’ve installed two beams in the cellar under the rack - I hammered them into place, a horizontal plank on top of each - it makes a lot of difference - i can jump in front of the player without mistracking. This, and separate... | |
| Why are my woofers pumping? I have been thinking: the main culprit is the cart-arm combo's low resonance. But is it? Much is in the blue, since the HFN test record is known to be somewhat problematical (e g dont use it to set antiskating), calculators may be crude and we don... | |
| Why are my woofers pumping? It seems that to use the single ended Kab filter from the balanced outputs of my phono stage (having tested that these sound better than the single ended outputs) I will also need a converter box. It becomes complicated. If KAB was next door of c... | |
| Why are my woofers pumping? Update: situation in the system at the cottage seems like with the main system at home. Vinyl records including DSD recordings of these made by the same cart-arm-phono-preamp in the main system, create pumping, more or less. Its not just Meddle, b... | |
| Why are my woofers pumping? Audiotomb - very interesting. I think my arm floats fine but will check when i get home. The HFN record lateral test shows very visible and sonic resonance ca 7hz while the vertical test is much less obvious (the test tone warbles a bit between ca... | |
| Why are my woofers pumping? I am mystified. Why do i see woofer pumping playing Echoes on my small cottage system which is 6db down at 42hz and probably not audible below ca 38hz? All hail to DSD? I play a rip / recording of the same original vinyl that gives pumping in the ... | |
| Why are my woofers pumping? I notice that Pink Floyd Echoes recorded from the LP on my system pumps the woofers also on my cottage system! | |
| Why are my woofers pumping? Thanks Atmasphere - yes the low reach of the amps in combo with the speakers may play a role. But with the Triplanar you dont have the problem. Do you know the resonance of your arm cart combo?Lathes - low frequency - ok - but if it happens betwe... | |
| Why are my woofers pumping? Listening to vinyl rips from main system, on my cottage system. No pumping of course - the Aurum Cantus speakers only go down to 40 hz or so. So music is limited but it also sounds nicely peaceful. No harm done - sins of omission not commision in ... | |
| Why are my woofers pumping? I already know that using single ended outputs from my phono stage curbs the pumping compared to using balanced outputs. But it also sounds much poorer! So to give the KAB a fair chance it would need an xlr to rca adapter (thanks, stereo5). Not su... | |
| Why are my woofers pumping? Thank you miner42 and stereo5. It may take some time, but i wish to try your suggestions. Although changing the arm or the cart might be optimal, no one so far knows for sure what works best in my system. | |
| Lyra Atlas experiences Thanks!Karl - happy you enjoy the Atlas, I do too, it is in a very high league. My cantilever is maybe not quite optimal but I have never sent it in for a check. Whatthe - I would probably think so too, with the Atlas SL. But my phono stage needs ... | |
| Why are my woofers pumping? Pink Floyd LPs - a quick test of woofer pumping1 The original LPs from the first years, not so much, deep sound is not recorded. 2 Notably more deep sound - increased pumping - overall sound is better - step by step - on Atom heart mother, and e... | |
| Why are my woofers pumping? stereo5: I don't diss the KAB. I am only saying, single-ended cables from my balanced phono stage to my balanced preamp sound much poorer in my system, compared to balanced cables. So a filter, to become a plausible option, would have to be balanc... | |
| Talk but not walk? Fully agree - geoffkait.Maybe 80 percent of my tweaks have not worked out. 20 percent have worked out very well indeed. Only an idiot would overlook that. Terms like "esoteric" - as if sound was somewhat alien... |
