Big Fun Box - Full Range Driver

Anyone build one of these? Seems pretty simple? 45 Liter box with a 3" PVC port.

A sheet of 3/4" MDF some full range drivers...

I've never really built / listened to high end full range drivers. I have read these full range drivers are not really good for Jazz or Synth type music? I dunno, seems like the driver can't do anything.

I'd just use stranded 16 gauge copper speaker wire. I doubt I'd try the cat-5 speaker wire.

But the trade off is super efficient driver for low powered amps. Anyone know a trade off between an 8" vs 10" Better worse?

thanks!

you need to up cabinet volume and change the port length if you are going to up the driver size if you want to maintain the same ratio. You need to use a calculator.

here is one

reason he is using cat 5 is because they are pair twisted and since you don't need a lot of power to the speakers, gauge is not as important.

47 Labs (http://www.sakurasystems.com/intro.html) equipment around small nimble single driver speakers too. I heard their equipment at Stereophile show many years ago and my impression was 1) coherence of sound, and 2) most importantly, directness with which music communicates musical intent (not in your face forward sound, but like layers and layers of processing have been removed from signal chain).

I would guess that something like simply recorded female voice would do great with this type of system. I really doubt that insane spl and earth-shaking bass would be a strength of this type of design.

Might want to look into an used pair of Klipsch Cornwall speakers (horn tweeter and something like 15 inch woofer). <$50 Dayton / Sonic T-amp (http://www.amazon.com/Dayton-Audio-D...s=dayton+t+amp) actually sounds quite good with them. Cornwalls were manufactured in 1980s and sound to me at more voiced for LPs (records) than digital sound, though.

I couldn't find the FE204 driver in stock anywhere, not that I searched every corner of the internet, but an initial search didn't turn up anything. Drivers are made obsolete with surprising frequency, a lot of the DIY speaker projects are difficult to replicate because the drivers are NLA. Hobby speaker designers have an expensive hobby, to save money the designers often buy clearance or discount drivers then develop a speaker design around the drivers, the drivers are frequently obsolete before the design is even published. That said, if you're interested in full range speakers it shouldn't be too hard to find a design that is well reviewed and uses a driver that is currently available. DIYaudio.com has a subforum for full range speakers.

Modern speaker technology has made the size of a driver somewhat irrelevant. I have a set of speakers with 4" woofers that will produce strong bass down to 40hz, there are 6-8" drivers that reproduce high frequencies very well too. The quality of the driver design and construction is more important than the size of the driver.

Well, I already know what type of box I'm gonna build. Probably a double bass box like this one.

Or if you wanted to spend the money you could order a kit like this...

http://www.madisoundspeakerstore.com/full-range-speaker-kits/fostex-bk-16-folded-horn-kit-pair/

But... I guess I didn't make my thread clear enough what I wanted.

I already own a T-amp. Trends 10.2... What can I say? I really like the sound of the Tripath 2024.

Hell, I'm not even thinking of going with fostex driver but instead going with a pair of AudioNirvana Drivers. They sell for about 200 bucks shipped for pair of 8" super drivers. You can pick a plan 32T x 10W x 10D inches (1.5 cubic feet or 43 liters) plan they give you. That and 50 bucks at Home Depot and an afternoon spent with a skill saw / hole driver / wood glue / screws and some silicon sealant sounds pretty easy. Probably just paint it and if I like it I might add some graphics later.

I guess I was asking if anyone listens to full range... Wanted to know what plans and drivers they were using. I am think 8" is probably the way to go and if I like the sound I could go with 10-12" and maybe a slightly biger box. I've never listened to full range except on a old TV or Car auto. But I've always heard people praise the efficiency and the sound coming from them. So I just want to get my feet wet to see if it's for me. One of the top reasons I am interested is because my low wattage amp that I like needs to have a 95-97 sensitivity.

I'll probably get my drivers from commonsenseaudio.
