Little help with REL subwoofers, please?

@deep_333, thank you for the suggestions. I've spent the last couple days reading about Rythmik subs. I'm impressed by what I read about both the F12 and the F8, but at 65-75lbs, they may be too heavy for me--but I appreciate the recommendation.

I don't know how small your space is, but mine is small (12x10) and I just put in two REL T/5x subs.  They were easy to integrate with the Neutrik Speakon connectors.  They move enough air to shake the floor and my listening chair when I turn it up (my neighbors likely don't care for it so I don't do it often).  I looked at Rhythmik as well but they are just too large for my space.  The RELs are the perfect size for me.  Since I bought two I asked the dealer if he could give me a discount and he did at 10%.  If you sell the two TZeros and buy a pair of T/7xs you might be able to swing a discount as well.  My in room performance for the T/5x is probably closer to 25-30HZ.  I've measured using REW and it's around -3db at 30HZ and -6db at 20HZ.  I am quite pleased with them.  They are fast and tight and have the sound I was looking for.

@jastralfu      I've measured using REW and it's around -3db at 30HZ and -6db at 20HZ.  I am quite pleased with them. 

As a past REL user I'd say even the manufacturer would find your measurement quite spectacular.

I have the LRS+ in my bedroom system (mainly used for home theater).

A sub was obviously needed for movie sound effects.  I got an Arendal 1961 s based on its reviews and feature set, and it not being too big or heavy with a 12.3 inch driver.

Bottom line is that it was very easy to integrate with the Maggies.  Setting the low pass to 50hz with a 24 db octave roll off gives me the rumble I want without it affecting the transparency of the Maggies.  (It also has parametric eq settings which I don’t use.)

@deep_333, thank you for the suggestions. I've spent the last couple days reading about Rythmik subs. I'm impressed by what I read about both the F12 and the F8, but at 65-75lbs, they may be too heavy for me--but I appreciate the recommendation.

@northman , Even with the Rythmik (technically the fastest subs out there), i wouldn't touch their 12 inch driver F12 or bigger for Magnepans...The FM8 is the sub with the smallest drivers they make.

This is also one of the challenges with MLogan electrostats. Their own bass driver can be perceived to lag a bit for the discerning ear... not a unique problem with Magnepans alone.

You could also try out that KEF KC62. It is a fairly recent technological wonder in the world of subs, if you ask me. A dealer like crutchfield has a 60 day no hassle return policy, if things didn't work out right. 

Thanks, @deep_333. Since your post yesterday, I've actually spent a few hours reading about the F8. It looks like a neat sub and offers some appealing controls (not all of which I understand). A few comments have called it "niche," and there aren't many reviews of it, but I like what I've read and it's clear that Rythmik has a superb reputation. And my system might indeed be exactly that niche. At 65 lbs, it's on the edge of what I can comfortably deal with, which is a consideration for me. Perhaps I'll wait to hear what my ortho says about my knee next week.... 

I will also take a look at the KEFs. For the moment, I'm enjoying the process of opening up my options, learning about different companies, and even exploring dsp and bass management. At some point, though, I'll just have to take the leap... I remain appreciative of everyone's help!

@m-db it surprised me to be honest.  I figured it would measure better than the specs, just cause my room tends toward bass heavy,  but not as low as it did.  Tbh, I don’t know how accurate the measurements are but they seem to be consistent.

At 65 lbs, it’s on the edge of what I can comfortably deal with, which is a consideration for me. Perhaps I’ll wait to hear what my ortho says about my knee next week....

@northman , Furniture dollies have largely saved my back over the years... Just unpack any sub straight onto a dolly and keep it on the dolly...comes in handy whenever you’re dealing with sub setup, moving them around to find optimal placement, etc.

@deep_333, YES. I was thinking along the same lines. Great suggestion! 

You’d be surprised how fast the Rythmik subs are. I’m using an F12 with Ascend Sierra Towers w/ RAAL ribbon tweeters and they integrate great to my ears.

I’ve eyed the FM8’s before but my use for them would be as low/mid-bass drivers, as they were intended, to add punch around 150Hz. Sub-bass (<80Hz) isn’t the type of bass that hits you in the chest.

Hello, @northman. Just so you know, if you decide on REL T/7x's, I'm about to sell a pristine black pair. I have all of the original equipment: boxes, power cords, high level cables, manuals, etc. I'd be willing to sell the pair for $1400 + shipping costs, so this could save you a bit of money versus new. If interested, please reach out: fitmannj@icloud.com.

Thanks to you both. I bet many can relate to this: I was moving forward on the subwoofer path, closing in ... and then life stepped in. In the last five days we've had two major weather events here in northern Vermont where I live, and my house and property took a serious hit. I'm now waiting on the repair estimates before I return to the more pleasurable audio prospects. Obviously the lesson is: don't delay  the fun purchases!

@northman I wish you the best in getting your house into tip-top condition once again...
