Does a subsonic filter have to be anything more than a basic crossover at the speaker?

[hugz]

thank you! I'll do that. Perfect compromise

Quick follow up question- Is getting a good equaliser more beneficial than a subsonic filter?

 

[lini]

Nope. I.e., if you need a subsonic filter, that's what I'd suggest you to get (or build yourself...). Whereas an equaliser would be a good idea, if you have limited speaker placement options with pretty different environment between the two speakers, e.g. one in/close to a corner of the room and the other pretty free-standing.

Consider this as a filter rather than a crossover. The advantage of a single driver is that you don't have passive circuitry trying to split up a signal into 3 parts and apply it to 3 drivers with different characteristics, in hope that it meshes well. A filter won't cause the signal to be split up into parts, but will purely burn off the lower frequencies that are inaudible. The signal already goes through lots of circuits/filter inside the amps, so I'm not of the opinion that a signal is pure and cannot be filtered- I just enjoy the lack of frequency splitting. Also, low power

It sounds like a subsonic filter on the tape may be the easiest solution

A passive crossover IS a filter or multiple filters and it doesn't work like that. The entire signal going to your full range driver will go through the crossover. Just because you're not dividing it more ways, doesn't mean you will avoid all the consequences.

A subsonic electronic filter is the easiest solution, but the best solution is Wayners. Figure out why you're getting excessive excursion and fix it. It's probably due to your physical set up being susceptible to shock, either through the stand or from the speakers.

My receiver has a tape-out and tape in. In this case do I connect the input of a filter to tape/out and connect the filter output to tape/in?



My alignment is perfect. I don't think the sl-1200 or Planar2 have azimuth adjustment



The "buy more expensive gear" solution is of little help. Turntables in Australia are expensive. In my state there's a used TD-160 for $1,800. I'm not buying that. One of my turntables is a sl-1200 mk2 so rumble is not a problem. Or shouildn't be



No it's not a rumble problem. The speaker cone expension goes along with the bass of the music, but just seems bigger than I would typically be getting off a CD. Either this is the nature of vinyl's bass or I may be getting feedback from my ported (horn) speakers into the tonearm during heavy bass and creating excess bass.

Either way, as my speakers don't create a great deal of bass, the cone is wasting midrange tightness attempting to produce bass that I can't hear anyway

There's no random/unexpected speaker wobbling. It only creates bass where there should be bass. There's just more speaker extension than usual

I received my KAB filter yesterday..for quick testing I hooked it up after my phono pre and problem is solved..I'm very happy with it. Tonight I will run it via the tape loop, either way in my case works but it will be interesting to see the difference sonics wise with and without..On my quick listen/testing last night everything sounded as it should.
I have tried to get to the root of the problem to no avail so rather than fiddle around endlessly the filter delivers what I hoped.
Cheers.
