Looking for a non-powered sub

I do have an amp that I want to use. It`s a Behringer EP1500.
I`m led to believe that to blend in a planar well, some outboard devices might do an overall better job.
Problem is, I don`t know what all I`ll need,and keeping the cost on the lower side of it all too.

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.
