MJ Acoustics Subwoofers v. REL.


REL has been the first name for many when it comes to subwoofers for music.
But I'm hearing more and more good things about MJ Acoustics, which someone told me is staffed by a gang of ex-REL personnel who decided to go off and do their own thing.
MJ make a model 200 which is pitched directly at REL Strata territory and it has received excellent press in the UK and elsewhere.
Has anyone got their hands on one over here?
It's time there was some decent competition for REL whose products, in my opinion, are overpriced by their importer, Sumiko. MJ subs are apparently better priced and look equally as well made (in photos), but I'd like to hear from any Audiogoners who have bought or auditiioned MJ Acoustics subs, to find out if the sound lives up to the good looks and reports.

I have a REL R 305 and like it a lot. It wasn't cheap ($1400 street) but it was better sounding than several more expensive subs. I have a 2.1 system and the R 305 sounds better than the Velodyne HGS 10 that it replaced, and that was no slouch. The REL disappears in my system and you only hear it when you're supposed to, to me that alone makes it worth the money.
I have an MJ Acoustics REF100 in a 20 X 25 living room and it sounds wonderful and plenty powerful for music with my floorstanding Dynaudio Focus 220s.

The MJ Acoustics sub opens up the sound of my floorstanders and changes them into sounding like speakers that came with very tight, authoritative, and musical 10" woofers.

I had a Velodyne SPL-800R subwoofer (the supposed winner of a shootout with the MJ) and didn't like it and sold it because it wasn't musical enough for me. In fact, I have tried several subs including a Velodyne HGS-11 and a Martin Logan Depth sub and sold them because they stood out like a sore thumb on certain musical passages and didn't integrate well. No so with MJ Acoustics subwoofers. Unlike the others, you don't turn it down to get it to blend in with music, you turn it up and let it sing. I will never play music without my MJ Acoustics sub again. I am so spoiled my Dynaudio floorstanders now sound weak and inadequate without the sub. They give you the perfect "Wow, thats what music is supposed to sound like!" No, the MJ is not the best Dinosaur stomping sub around but it is adequate when you turn it up for home theater. But for listening to music and integrating with your speakers, the MJ Acoustics subs are PURE GOLD.
Hi - had a 100 for awhile and quite liked it.

yes, it is the same type of amplifier tap/Speakon set up as REL - I hesitate to say the same because I don't know the pin assigns

yes, it is very well made and nicely finished

it is very adjustable with a LED that shows peaks and several filters plus 180 phase (IMHO one of the most essential set up tools)

no this one did not have a remote

yes, this one was a downshooter like the traditional RELs

I thought it integrated well with my 2 channel system and have no doubt it would have ripped in a 5.1

I bought directly from the distributor what seems to be a discontinued model - as Itball noted, they seem to be in the process of getting their US distribution together - not sure what the grand design is.

I sold the unit - must say there was little demand from the AGon community - but would not hesitate to buy another - I went the other way to bigger floor standers
Here is a link to an Audiogon member who tried MJ subs in their system and compares them to Rel and Velodyne.

I have not heard any of the MJ Acoustics subs. But I have the REL B3 and Synergistic Research Rel Spec Phase II X2 cable. The B3 is very musical and blends seamlessly in my system. It easily disappears and is very detailed with lots of control and finesse. TAS did a review in its August 2006 issue. I thick the review was very accurate.
Not a comment on the sound but perhaps some useful information anyway ....

I was thinking of buying two of them a few months ago based on reviews and my need for 2 small, great subs. I talked/emailed with a dealer that was a nightmare, didn't answer my questions (some he didn't know the answers to and others he simply avoided) and had almost no stock ie. limited colors etc. I then contacted the US distributor and found a similar story - not much stock in the country.

Seemed to me like they are just getting going here and have very limited supply and dealers. The chain of support in terms of technical help and/or repair work seemed confused as well which made me nervous. As a result, I would want to buy from committed local dealer if I was you.

I then happened to read a review of the Pro 50 in a British mag - it was up against several other small subs in a shoot out and the very clear winner was the Velodyne SPL-800R although the MJ fared very well too. They claimed the much lower power on the MJ hurts it versus the Velodynes.

I ended up buying the Velodynes used and like them very much with my Totem Hawks.
I was strongly considering a REL B3. I had a REL Strata-II several years ago and was pleased with it.

The B3 seems to be the recommended step forward from the Strata subs.

I have recently stumbled onto info regarding the MJ Acoutics line of subs and am looking for feedback from those who own or have listened to the MJ subs. Especially if you have compared them tot he REL subs...Brittania Series specifically.

I am considering the REF 100 MkII for use in my approx 14'W x 17'D x 7'H.

Those who are familiar with the MJ subs, please share your experience...are they "tuneful"...do they accurately portray the detail & "timbre" of the music, or are they just producing low bass "tones"?

Any thoughts on the down-firing drivers vs. the B3's front firing driver?

Is the wiring configuration via Neutrik Speakin cable the same w/MJ's subs as it is with the REL subs?

Any experience that you can share is appreicated.
I have the MJ Ref 200 and find it to be a very nice match with the Talon Raven's, Khites and PSB speakers. It is VERY adjustable using both high and low frequencies inputs and cross overs. Pitch definition is good, SPL output is very good for its small size and it has mated well with all of the speakers I have used with it. On the down side, I find the remote control impossible to use effectively for making adjustments. However, once it is dialed in, its "money."
I have a rel b3 -- it mates really well with maggies --- very fast and tight, without being bloaty. I have heard that MJ does a good job with their subs, I have not had one in my room.
I also would like to know if anyone has compared a MJ Acoustic sub to the REL's, particularrly the Strata III. I'm going to use a sub with magnepan 1.6's. Matchstikman the MJ Acoustics website is here: www.mjacoustics.co.uk .
Wrightstuff,
I'm in the same camp, I posted almost the same question (between Velodyne & MJ Acoustics) and came up with one answer.
I contacted MJ Acoustics, talked to a dealer & checked out their testimonials on the website and decided when I'm ready, I'll go with a pair of the REF 100's.
