JL Audio Fathom

I have owned two F112V2's for close to six years now and have never had an issue with either one. (I hope I do not come to regret that statement) Could be the, law of averages at play here...the more units you have in the market, the more that could end up needing service.

Well, decision time is near. I have the $$$ set aside. If not for new subs, I was going to get a McIntosh MT5 turntable. I currently have a a simple audio technica. If it was you, JL or MT5? Keep my day interesting haha. 

The good thing is if you go JL Audio they have great service, as one day you will need it… 

I haven't been without subwoofers since the sixties.

After giving away my early Technics SL 1200 for a belt driven Well Tempered Classic I experienced that Basis Audio's A.J. Conti was defiantly onto turntable drive belt irregularities and aging. 

I missed my SL's drive power and torque from day one. I should mention I've been conformationally swayed by Oswalds Mills Audio's Jonathan Weiss direct drive philosophy. After over a decade without an audio purchase I'm currently squirreling away for an affordable Technics SL-1200G-S.   

Dear @upstateaudiophile :  The main issue and target with added subwoofers is to achieve first than all a benefit to lower the IMD in the main speakers as can be in your WA Sabrina X and a side benefit is to have a lower and better bass range handled by a dedicated amplifiers and woofers in those true active subwoofers ( I'm not talking of your ML but any self powered true subwoofer. ).

To maximization those 2 targets you need that the subwoofers must be sealed design and needs to comes with not only low pass crossover filter but it's desired high pass crossover filter too to take advantage and really lower that high IMD that your Sabrina has in this moment due that its woofers crossover the mid range at around 300hz and from here down to 30hz and this is what develops that IMD levels that with the sub high pass crossover filter ( or external High pass. ) will permits a lot better quality levels in the Sabrina mid range, high frequency and mid-bass ranges.

To all those happens and you really can enjoy your system as never before you need to croosover both crossover filters at around 80HZ. Other great benefit that you will have is that at 90hz the Sabrina woofer impedance is at 1.1 that it's really low to handled with aplomb by almost any amplifier and this fact develops higher distortions that makes a degradation in all your room/system quality level performance.

Your ML subs can't do the job neither the JL ( has to high THD. ) and you can go with a noy to expensive alternative like these Velodyne that measured at 20hz and over 100 SPL the lower than 0.5% THD that no JL can even dreams:

Digital Drive Plus - Velodyne Acoustics

Regards and enjoy the MUSIC NOT DISTORTIONS,
