I'm thinking of building a higher end 2 way speaker using a 15" woofer and can't make up my mind which model. The main goal is strong clean output from about 60hz up in a midsized cabinet (I don't care if it's ported or sealed), but with the ability to run full range in a larger enclosure if needed. Demodulation ring is a must. A&E woofers will be part of a different idea later. The first 2 FaitalPros have been looked at fairly close and I've got one of each. I'm not really worried too much about cost for this design.

FaitalPro 15FH520:
http://www.parts-express.com/faitalpro-15fh520-15-neodymium-professional-woofer-8-ohm--294-1275

My understanding is that this is suppose to be a very nice woofer. F3 is 65hz in a 3.5cuft sealed box. F3 is 42hz in a ported 4.5cuft tuned to 33hz.


FaitalPro 15FX560:
http://www.parts-express.com/faitalpro-15fx560-15-neodymium-professional-woofer-8-ohm--294-1277

Another beast of a woofer with an interesting look. F3 is 45hz in a 3.5cuft ported box, or 61hz in a super small 2cuft ported box. Doesn't like sealed boxes.



B&C models: Are there any that will trump the FaitalPros? They seem to be changing their line up right now, so I'm not sure if any of the new woofers are better than this one:

15TBX100:
http://www.parts-express.com/bc-15tbx100-15-woofer--294-670

I'm open for suggestions on any other B&C woofer that I should consider.


JBL 2226H This model always seems to get good reviews.

Not fussy at all what high end woofer you choose but the size of the cabinet concerns me.
I know I would really like a large old school cabinet like a klipsch cornwall/ altec Lansing model 19 which would definitely be over 6cf, full range into the low 30hz with high sensitivity over 100db/watt, 6 ohm for any modern receiver.
You already have some good mid range cabinet sizes in the tempest/ sentinel. I think it would be good to go old school and offer your first tower version with minimum 38" height.

Also I assume you will be using a seos-15 horn...the faital pro 142 tractrix horn plus the 140 cd looks like it would be an awesome combo too as that cd ranges from 500hz to 18.5 kHz...I know you will say no to a non seos horn but just thought I would throw that at you.

Yes, I would be using the SEOS-15 on this build.

My first pick was for the FaitalPro 560 because it appears to be a beast of a woofer and the octagon shape is kind of neat. It does require a ported enclosure though. But the box would still be the same size as sealed for other models, so maybe it's a good choice.

Any ideas for the B&C models?

I'm not sure if Celestion makes a higher end 15". 18 Sound is hard to come by.

You have the usual suspects I know about already listed. I would vote for either the JBL2226H or the AE TD series. That said, cabinet size is not a huge concern for me. I could easily accommodate 4-5cf mains as long as they didn't exceed ~19" in depth. This is the route I originally wanted to go, so it is exciting to see this making its way forward.

FaitalPro 15FX560.... for exactly the reason that Sibuna stated. That is a fine looking beast!

Why is this one a beast of a woofer??
Is there at least a tiny possibility that this will go in tower version larger than the fusion-15 cabinet??
No woofer preference at all but since you want high end 2-way more than the fusion-15, then full range
should be given a high priority whether matched with subwoofers or not...
The fusion-15 cabinet looks like a huge bookshelf cabinet which is fine but definitely would look better in a tower
version around 40" in height. Therefore I hope you will offer at least 2 cabinet size baffles at at minimum: fusion-15 size and a tower size.

A&E stuff will be handled differently, which is why they aren't listed with these. I think there's a design out there using them now and it might be tweaked later.

Lemans24, second sentence in the first post answered those questions. wink.gif

That model is quite smooth up and over 2khz with an X-max of 9.5mm, but can go up around 20mm before damage. Works good in a small ported box or a larger ported box. Has a demodulation ring and light weight with a neo magnet. The 520 is also a very nice woofer, so it's a tough call.

The octagon basket is a nice touch, but there's a big rubber gasket on the outside flange that takes away from the nicer look. Obviously we probably shouldn't pick looks over performance though. smile.gif

Just an FYI, I think they're both breaking up above 1khz. You can see the off axis is being mirrored. That behavior is a result of cone flex.

What size range for a larger enclosure would be acceptable to you, so I can model these drivers in WinISD??

FWIW, Geddes is going to be using the new neo version (NBX) of the 15" B&C in the New Summa, and will presumably move to the NBX 12 in the revised Abbey that he's working on. The prior versions used the TBX line.

"The new B&C NBX line of woofers are very impressive. The lower weight got rid of some persistent resonances that were problematic."

Are you intending to use the "fully loaded" compression driver on these designs?

I would be a 18 Sounds advocate because I order them all the time. I would have suggested the 15MB1000, 15MB700 or 15MB606. Just depended how high you wanted to crossover and what size cabinet. They all do well enough to cross at 1200hz and possibly higher with the 700 and 606. BUT I also like the Faital's but they are always much more expensive for me.

JBL 2226H would get my vote I think

Since cabinet size has not been specified, then go with...JBL 2226H.

I want this to be better than a JTR 228 which comes to around $1300 per cabinet

No, I haven't researched the 15" market at all. You could make those work quite nicely, but I'd be inclined to cross over around 900hz and do it hard. Are you designing this Erich? You could ask the designer to pick something he thinks will meet the goals...

What ever woofer you choose, if done right, this will be a very nice speaker eek.gifsmile.gif

Uh no, I'm not designing this one. I'd fail pretty hard if I tried.

I'm sure they will be crossed low. Even debating a 3 way design to really go crazy.

3 way sounds pretty awesome biggrin.gif What would you use for the midrange driver ?

Anyone ever done something with say two 12" or 15" drivers, two 5" or 6" drivers and a single DNA360 in the middle ?

I'd be thinking along those lines. But it is tricky to pick a mid then cool.gif

This is partly why I think speakers like this should have a more hands on approach by the end user, like chop shop's build. Realistically, a 15" 3-way should use active DSP, and meet the users goals, including room constraints. Offering a plug and play solution is fine too, just not as good as it could be perhaps.

8" midrange or dual 6" mids would work okay. I've drawn all of these ideas out over the past year, just haven't had time to get them going. I've got a booklet of about 40 designs, but they all can't be done. rolleyes.gif

I had a crazy idea back before I was pestering Tux about the 1099 design that used dual 15's. But the price was kind of eye watering at over $1250 just for parts.....so the 10" was born instead.

Dual 6 would be better. Directivity would collapse with a single 8. Dual 8s would be tricky, dual 7s if any exist...

I wonder if he looked at the 15NW76; it has a demodulating ring and much better controlled breakup.

It has a 3 vs. 4 in. voice coil but I wouldn't think that's an issue for home use.

I looked at the 15nw76, but wasn't sure if it was better than the TBX100. But I'm also wondering if the TBX100 is going to be discontinued soon with all the changes they're making.
