Why do my bass drivers shake violently listening to vinyl
It is the nature of the vinyl format to have this rumble. Never seen anything like that on any of my high efficient drivers using vinyl only format for over 25 years without any subsonic filers! Not sure it helped in any way but I kept the subsonic filter off when breaking in my Tannoys. Right, it’s absolutely useless with a proper drivers like Tannoy Dual Concentric (I have 15 inch and 8 inch Tannoy speakers ) or any other full range drivers like Zu and related. |
@chakster, it helps if you have a driver that actually makes bass and have an amplifier with the power to make it happen. But, no bass is better than bad bass. This is a solution we used for decades until decent sub bass drivers can along in the early 80s. You use subwoofers for two reasons, to make real bass below 80 Hz and to take that part of the spectrum away from your main speakers because it screws them up. It was a tough sell back in the days of analog bass management. Now it is a no brainer. |
I use professional MAIN studio monitors that is capable to reproduce bass from 38Hz - this is more than enough for me (and I don’t listen to digital) @mijostyn You can check the manual for my Tannoy "15 DMT mkII here. Lots of nice records mixed and mastered on these monitors. Those are 200w with 101 dB SPL and I drive them with 1.5w single ended Yamamoto A-08s with NOS 45 tubes from the 1940s. I could lose hearing using those Tannoy with 100w solid state amp. I also respect neighbors above and below my flat in the same building :) Sold my SUB a long time ago and never looked back. SUB is for home cinema or for bookshelf speakers, SUB is for digital source. Basically SUB can cause too many problems in a small and medium size room, the wavelength of low frequency is so long that you need a HUGE room or very special treatment. The lower you are going the more problems you create (standing waves), people just don’t understand it. I’ve come to high efficient full range drivers and low power amps a long time ago. Happy with Tannoy Dual Concentric drivers, especially 15 inch drivers. No ruble with vinyl (with my speakers), never. P.S. I'm just trying to say that vinyl is not always a rumble. |
As others already pointed out, the physically visible woofer pumping is typically seen when the woofer is mounted in a ported or vented cabinet that does not backload the woofer at extreme low frequencies. You’d never see it with acoustic suspension type speakers for example. ( I don’t know about Zu speaker designs or how your Tannoys are enclosed.) incidentally we’re seated in the Kennedy Center, and my first live post covid concert is about to commence. |
