Looking for a non-powered sub

I have a pair of Audio Artistry Dvorak subs. Each sub is a dipole sub, with one 10" woofer firing on the front and one firing on the back. They are a great match for planar speakers. I am driving them with a Hsu Research power amp with adjustable crossover modules.
I will consider seling them.

Take a look at the non-powered New Original Subwoofer by VMPS. It was designed to mate with the Quad ESL, and actually could be used as a stand for that speaker. Last I checked, VMPS subs could be purchased either pre-assembled or as a kit.

How low in frequency do your Maggies go? If you need the subwoofer to go any higher than 80 Hz, you will probably get better results with two subwoofers, one underneath each Maggie. This is especially important if you are you using your system for music rather than HT. You might be able to buy two VMPS subs for not much above $800 if you don't mind buying used.

If you want a true DIY subwoofer, i.e. you buy the raw driver(s) and design and build the cabinet yourself, you can chat with other such eccentrics (including myself) at www.diyaudio.com.

The large majority of subwoofers on the market are active (internally powered). I prefer passive (non-powered) subs. The internal amps included in active subs are generally of inferior quality compared to stand-alone amps. Also, the interior of a hot, vibrating subwoofer cabinet seems like the worst possible place to put an amplifier. My pre-pro does the crossover job, so I don't need a separate component for that. If you do need a separate crossover unit, they are available at reasonable cost from VMPS and many other sources -- or build your own, with a little help from other DIY'ers.

Gallant, my room is only 14' x 18' with 9' ceilings. Dipole subs might be pushing it don`t you think?

Java..No interest in wood working, but a put-together kit is interesting.
I`m leaning to the VMPS especially if they can be had in kit form.
In the VMPS line, which sub would you recommend in my room?
I want tuneful/musical bass, not what I hear going by me on the road if you know what I mean.

Which crossover would you use to limit the 1.6`s from seeing too much bass a Paradigm X-20, NHT X-2 or other... ?
Thanks,
Steve

The VBT (TBI) Magellan passive subs are small, attractive and very quick and tuneful, and should mate well with your Maggies. Put one in your corner, or for even better response use one beside each speaker.

If you want to move, more air, I've also used the RBH 1010 subs with great results (two 10" aliminum drivers). Clean and tight. They make both a passive and active model.

I agree with Java that the interior of a hot, vibrating subwoofer cabinet is not the best place to put an amplifier. People spend tons on amp stands and footers and vibration control and then use powered subs where there's more vibration going on than anywhere else in their system.

BTW, I also agree with Gallant that diploe subs are a really good idea with dipole mains. They're a great answer for problem (boomy) rooms. I'm presently using some Linkwitz Orion diploes to great effect.

Hi Steve,

Well, I just read up on the Maggie 1.6 and now I fear that my previous advice may be worth exactly what you paid for it. :)

I did not realize that the 1.6 is a 2-way planar design with bass extension down to the 40's. In that case, since you are 100% music, why do you think you need any subwoofer at all? If you like the sound that Maggies are famous for, why risk messing things up with a big old-fashioned cone? You could start with the Maggies by themselves, and then add a sub later only if you feel like you are missing something.

If you do decide you need a sub, you might be able to get away with a single sub, since it would not need to go higher than 60 or 80 Hz.

Among VMPS subs, the "New Original" would probably mate well. I have not heard any of the other models mentioned in this thread, so I can't offer any comparisons.

I don't have any suggestions for a crossover either. Your Maggie dealer or the Maggie website could help with that. The website seems to indicate that the Maggie 1.6 can handle a full-range signal and doesn't need to have any bass withheld, so the crossover would only need to consist of a low-pass for the sub.

Also, disregard my idea of placing the Maggies on top of the subwoofer. They are much too tall for that.

I have read nothing but fabulous reviews of the Linkwitz Orion, but even in kit form, it is substantially more expensive than the Maggie 1.6.

Bottom line: for 100% music, the Maggie 1.6 might very well be a complete solution for you, with no subwoofer at all.

Have fun!
