Bandor 50MM Modules in a Sub-Sat System

Karl71 · 20th September 2008, 04:01 PM

Has anyone tried a DIY version of Bandor's Trident II Sub-Sat system? It looks quite doable.

Since the Jordan/EAD JX6R HD has apparently become unobtanium, I am now seriously considering the Bandors, specifically the 16 Ohm version due its flatter response compared to the other units in the 50MM module line. The Bandor ad in AudioXpress sparked my renewed interest.

BTW, what has become of Seventh-Veil?

Any thoughts?

Regards,

They went belly-up.

Scottmoose -

When was that? I hope that won't affect Bandor.

Beginning of the year IIRC. I don't see why it should affect Bandor too much -they were just a customer, and, given that one assumes they went under because they didn't sell too many speakers, I doubt the fiscal loss will be huge. Bandor, I imagine, like Jordan & Mark Audio, will have their units made in small batches, so they'll all go through patches of poor availability.

FWIW, I suspect their cabinets were very expensive to make (and probably needlessly so, irrespective of PR nonsense). Result: they were only ever likely to be a pricey niche product, irrespective of how good they may, or may not, have been.

Scottmoose -

Have you ever heard a Bandor 50mm module? The current exchange rate is not the most favorable, so I want to be fairly sure of the purchase.

I have played around extensively with Fostex FF85K units and love what they do. They sound spacious and very open. However, they are a bit tizzy in the treble and have little bass, on their own, of course. I expect that the Bandors would be a big step up in the treble and would do very nicely with a sub.

Yes. It was a while ago though. Not too far off the FF85K actually. I've never directly compared the two, but by fallible memory, it's probably a bit cleaner at the top end, compared to the stock Fostex, but less sensitive. The cabinets were rather different, but I can't see there being a great deal of difference in the LF.

Bandor specifies a sealed 1 or 1.5L cabinet (5in.x5in.x6in. internal). I would wall-mount and crossover to a sealed sub at the recommeded freq. of 150 Hz.

Scottmoose · 20th September 2008, 09:30 PM

Then their LF performance or lack thereof doesn't matter (ditto the Fostex). You can get some extension out of both, but you'd have to horn load them.

Karl71 · 20th September 2008, 09:46 PM

That is true. With a sub, LF won't be an issue.

Dispersion, clarity, and well-controlled HF are my goals, and the cone of the Bandor is significantly smaller than that of the FF85K. The 16 Ohm version of the Bandor also seems to have flatter response than that of the FF85K and the other Bandor 50MM modules.

I hope the word is subs, plural, rather than singular, or you'll run into some major problems in the LF if crossing at ~150Hz. 70Hz is about the limit of use for a single sub if you don't want directionality issues, and preferably [a lot] lower.

Depends what you call significantly smaller -the FF's cone is ~29cm^2, the Bandor 26cm^2. Not that much in it. It should be nominally the better driver though -one would hope so, considering the price, although the extra sensitivity of the Fostex has its uses. YMMV as always.
