I have an LP12 with an Akito1, this has a shure V15VxMR.I've never had any problems with this set up and quite enjoy the sound... until now. I've hooked up a sub and due to the high compliance of the cart and relatively high effective mass of the arm I'm getting woofer pumping on the sub.
I figure I can either:
-Change tonearm: Any suggestions on a low effective mass tonearm? I have a SME 3009 however it's happy on another turntable and I've heard the SME and the LP12 don't get along so well.
-Change cart: Is there anything as dynamic with the bass slam of the V15 out there?
-Ditch the sub: no (hehe)
-Low freq filter: no thanksAny input would be greatly appreciated. I'm not quite sure what I'm going to end up doing with this.
Follow Ups:
Morch UP4, red dot armwand is a great match with my Shure V15VxMR. Low enough mass to probably fill yer bill. If not, there's the green dot armwand, which, at 3.5gm is really lightweight. Been my experience that if you want the bass to be balanced with the rest of the frequency spectrum, go up one armwand in weight from what Morch recommends...and they recommend the green dot armwand with the V15V. And yes, I DO use it with the stabilizer deployed, and if I had your problem I wouldn't hesitate to use a high quality infrasonic filter.
You may have theoretical slight insertion loss, but the gains by using it would probably more than offset the loss.
I'm not quite sure why you don't want a subsonic/rumble filter when it will not only eliminate your problem, but probably improve your sound quality as well.
come up with either the effective mass of your arm or the compliance of the V15. Without either it is hard to suggest a solution. However, if you are looking for low mass arms, the SME III or a Black Widow will fill the bill. Either can be had for low change on EBay.
Compliance of the V15 is 25 and the effective mass of the Akito is 10.I'll definitely check out the black widow.

Do you have the brush on the Shure up or down? If you have it up, you can try playing records with the brush down - just remember to add 0.5 gm tracking force to compensate for the brush being down. The brush was designed in part to minimize the subsonic resonance that can interact with warps.
I'm familiar with the brush. Seems like a bit of a stopgap solution to me though because it affects the sound quality.
From what you have written it sounds like you have not tried the brush. Yes, some people have reported that the sound is better with the brush up in an optimum situation, but since you are NOT in an optimum situation, and since it will cost you NOTHING but time to try it, WHY NOT? You may find that the removal of subsonic problems from your system may IMPROVE the sound and solve the problem, in which case, keep using it and stop worrying about what other people have said - this is YOUR SYTEM, NOT THEIRS! Seems to me you have objections to every possible solution - you don't want a subsonic filter, you don't want to spend money for another tonearm or cartridge, you don't want to try the brush. The brush, at least, is ALREADY THERE FREE OF CHARGE. On the other hand, if it sounds worse, you may have to actually spend money to solve the problem and you may not be any happier at the end (worst possible case).Shure actually designed the brush to damp the subsonic resonance inherent in ALL arm-cartridge systems, and also to make cartridge more compatible with a wide variety of arms, so in that sense it is NOT a stop-gap.
I have tried the brush. It makes a difference to the sound.No, I don't want a subsonic filter. But other than that I'd be open to a new arm or cart as long as it suited what I wanted. That's basically what I was asking suggestions for.
It might help if you re-read my post, then you would get more of an idea of my situation.
Nice capital letters by the way, they make you look very clever.
Um, OK. I'm not sure why the Akito should cause such a problem with the Shure, as the effective mass is not that bad - 10 gms is still within the recommended range with the Shure. That said, a couple of low mass arms that are good, and relatively inexpensive, are the ADC LMF-1 and the Grace G-707 Mk II. Both have effective masses around 5-6 gms. The Grace in fact used to be the recommended combination with the Linn LP-12 before Linn started making the Ittok, and both arms are relatively light, so should not interfere with the working of the Linn suspension. The low mass arms will shift the resonance frequency up by maybe 1-2 Hz, which might be enough to make a difference.
