1. But...
2. Yeah, I'm a n00b when it comes to building speakers. But my friend is very experienced. May be he can build it for me.
3. Beam ?
Can you elaborate ?
4. Thats a wonderful idea.
5. Econowave !
let me google it !!!!
Thanks for the reply, appreciate it
Happy Birthday to you
Thanks man !
It would be awesome
FF105wk is a very nice driver. We have ours in Vampyr-V. This enclosure probably gets the most bass from this little driver. Your little reflex may be a bit shy on bass depth and level toplay metal at louder volumes.

But, what about the crossovers ?
Do you think a digital crossover is better than an electronic one ?
I also have some electronic music (Armin va Buuren, Paul van Dyk etc) and would that second type system sound too smooth for it ?
TBH, I like a slightly bright, revealing sound from my speakers
Huge speakers might not be a great idea. My parents are a bit conservative and there is a big chance that I might get married this year. I don't think she'll like it
But, if I can "hide" it somewhere...it might work
The FF85wk by itself is limited in bass extention and how loud it can play. Mate it with helper woofer(s) and it becomes very capable with all types of music.
A prototype of this FAST stunned at lot of people at the 2013 VI diyFEST. It is uFonkenSET with a twin Peerless 830870 in a Woden designed ML-TL as stands. PLLXO at 240 Hz. So you can start with the satelittes and add bass later yet retain the tiny footprint.
I just got back from Bernie a devlopment of this concept that doubles the number of woofers (in an ML-Voigt -- no pictures yet). They are gorgeous, 15mm ply with 12 mm solid yew veneer.

Beaming is a narrowing of dispersion as freq goes up iirc.
Nothing that a bit of toe-in cant help
That looks awesome !!
But a helper woofer means crossovers ?
Does it affect it ?
Can you share the deign here or is it a commercial one ?
Is it possible to deign a transmission line which gives emphasis to high frequencies and use a helper woofer to fill in the low frequency part ?
@sippy
Thanks for the heads up :thumbsup:

By electronic you mean analog?
It comes down to execution and what the kit around it is.
Digital are most often more versatile. But best used with digital source directly into them.
Welike designing speakers to work within the limitations of PLLXO. They have only a half dozen passive parts for stereo 2-way.
dave
Yeah, analog !
My PC's sound card have a configurable sub-out. (max is 120hz IIRC) Can I use it ?
Yes, one way or another. Yes, but it is quite low where one can eliminate many of the evils of cross-overs. Easiest to do if you biamp.
There are a zillion options for FAST. Quite a few examples in the forums. The design pictured in Post #44 is commercial, but the plans are cheap. (the plans for the BigVent ML-Voigt in Post #42 also cost http://wodendesign.com/Vampyr-V.html)
The box you put the speaker in is intended to modify the response at the low end of its range. Higher up you work hard to have the box not affect the response.

I am using B&C 10PS26 10 inch pro-drivers in BIBs with a Faital Pro 3 inch FL driver in a "FAST" system. Passive 6 dB/octave filters.
It sounds very powerful, clean and dynamic. Meshugga is a real treat on this system.
I can run my QSC RMX1450 to near clipping without any bad sound from the speakers, but the music can be heard several blocks away and everything in my house is pulsating with the very powerful bass.
The sound is very physical with a natural timbre to large instruments.
The best property is that similar to many large hornspeakers, it does not change character when turning down the volume. The bass is very effortless, clean and dynamic even at very low volume. Perfect for late night listening when my kids are sleeping.

Good to hear. I'm on my own "belle"ish journey myself - lucked out on some kappa 15 but bad weather here so can't cut plywood outside for at least another week or two
Altec 511 - if one can land a K55, sound pretty good - let it ring - piles of mortite on the main body of the horn sound like ring plus soggy crud - sounds "weird" - some mortite on the lips is ok - lead shot on the upper lip would work - I tried little pieces of car damping material kinda like eNaBle but that had no great effect upon the cowbell nature of 511 -- there were some buyout heavy magnet Selenium phenolic compression drivers at Partsexpress a a few months ago but I've not tested mine to see if they can reach 500. hard rock is something usually played at a level where its just about "felt" - not good to listen real loud for a long period but can be fun for a song or so as long as the material isn't too compressed. (who has a good de-clipper? - how about something that emulates a DBX 3BX?)
those FAST cabinets are beautiful !

So, I'm wondering if there are any full range speaker designs out there which goes with "loud"ish rock music ?
BTW, here are some of my thoughts regarding speakers.
1. I play my Magnat Monitor speakers (92 db) at around 40% volume using the AS500 (85W @8ohm. ~110W @4ohm).
2. I l have a lot of "heavy" type of music.
3. Off axis response should be good
4. A flat frequency response would be great but TBH, I like a slightly bright, in your face kind of sound signature.
5. I might get a class A amp with low power output...so it would be great if has good sensitivity.
6. I'm not good in building stuff but thankfully, Bibin has agreed to help me out in this matter.
I think we need to nail down "loud"ish.
Because (in a sentence) if you do crank it, then you'll need some sort of multi driver system:
A) bass 'fulranger' with top end help
B) top end 'fulranger' with bass help
If you don't crank it then you may be able to squeak enough low distortion bass out of a true fullrange.
[And I of course mean this is the utmostly general, not-bashing-yer-fullrange, non-flaming way possible ... ]
So, I think we need:
1) room size, shape, situation (speaker posit, entranceways etc ..)
2) some sort of spl measurement (1V/1m; or list position; ...)
Do you have a suitable mic? Err, sorry to foist a job on you ...
Cheers,
Jeff

hi Circlomanen - that B&C 10ps26 looks very capable and is bargain priced in the US - what are your BIB dimensions?
(I'm looking at 10fw64 for a little Karlson -- know anything about that one?) http://www.parts-express.com/bc-10fw64-10-professional-woofer-8-ohm--294-5930

There's a zillion ways to do this. At some point a choice needs to be made. One good choice would be to take sreten's SLS woofer in a sealed or vented box, and cross it to an FF85 or FF105 at the baffle step, say 300hz or so. I'd suggest a short stuffed TL load for the FF, and a series crossover, or PLLXO. The crossover alone will give you plenty to tweak... This would be a pretty good compromise between high resolution and rocking ability.
If you must use a lower crossover and sub out, go with the FF105 in a met, to give you some support in the low mids / upper bass.

At the moment I am driving my BIB with a single end 3 watt transconductance Triadtron amp.
Yes the bass is almighty powerful. I don't need a dedicated sub. I have a pretty decent response down to about 27 Hz and i can hear stuff in my house rattling at 22 Hz.
I have run 500 watt of bass (bridged QSC RMX1450) low-passed at 80 Hz into one of these, and it was painfully loud. The bass was clean, very big lifelike and dynamic. My whole house pulsates with the music and paintings jumped down from the walls.
They are 31 x 46 x 182 cm. Everything is built of 18 mm plywood and the baffle is two layers for a total of 36 mm.
The Faital Pro is 3FE20 (older version of 3FE22 with Nd magnets)
Cheer SPL is not everything, and I would not keep them despite my wifes protests if they did not deliver. I have built a large MLTL with Beyma 12P80Nd, but they don't come close. They sound so dull and lifeless compared to my BIBs that i have not found the time to build a stereo pair yet.
I do have two BIBs though, and i will keep them.
I can't really imagine building another pair of speaker for bass in any foreseeable future.
Build BIBs!
Cheers,
Johannes
