I was wondering if there are anyways of getting a nice sound from a small enclosure. I guess the hard challenge is getting good bass, so I'm guessing a reflex enclosure would work here...
High sensitivity drivers would be good also, as I'm using a 41hz.com amp6 to drive everything, which is good for 20W per chan at 4 ohms.
I was thinking maybe the eminence beta 8 would be good for bass and mid duties, and some random tweeter? Even then I think 8" is a bit big... I don't really know where to start really, but I think it would be good to keep it simple and go for 2 way.
I'm not really after a finished design (tho that would be nice), I'm just after some suggestions for various drivers, preferably ones that are available in the UK.
Overall, I'd prefer a good amount of SPL and a large frequency range, I'm not so bothered about a flat frequency response. I plan to use these speakers in lots of different places...

Hey Mike,
Do you remember what I told you about ProAc Studio Monitors (Studio I MK IIs or Studio 100s). Try to clone either. At least go listen to them somewhere!
Unfortunately, Richie said it all. Forget 20 watts into 4 ohms for this application/footprint with authoritive bass.
Hopefully the Celestion can be a good choice.
In the ProAcs, the mid/woofers are Scanspeaks and can be bought from ProAc (slightly modified for them by Scanspeak) for less than 100 pounds each and the tweeters are also scan speaks and can be bought from any retailer. The crossover isn't too complicated. The box making is up to you to make well. It is front ported. However you will need 60 watts per channel into 8 ohms for these to rock. You can probably make them for a total of less than 500 pounds. Or like I suggested last time, look for them used.
I don't have the experience some of these other guys have so I am recommending what I know and what I am sure you will be extremely happy with. But after building these, you will want to look at everything else in your system. I hope the other guys can give you better news.
Good luck!

I'm not sure it will meet your requirements, but this is a suggestion I made to a very similar requirement recently:
http://www.diyaudio.com/forums/showthread.php?s=&threadid=118633
The Beyma 8BX should be good from about 11 kHz down to about 33 Hz in a 30 liter box - and NOT require baffle-step compensation.
What do you consider compact? I mounted a pair of Hawthorne Silver Iris coaxials in some minimalist winged baffles as a Christmas present for my son.
Pictures at:http://www.hawthorneaudio.com/photos/displayimage.php?album=93&pos=2 I added grille cloths after the photos were taken.
The baffles are just a bit taller and wider than the 15" drivers, but only 8" deep at the base and 4" at the top. They won't exactly nestle onto a desktop, but they work fine on top of the pair of armoires in his college dorm room. At 95 dB/W or so, they'll make plenty of noise with an Amp 6. Bass is useful down close to 50 or so. The top panel makes a nice handle and they don't weigh much so transportation is easy.
The drivers aren't exactly cheap, but the xovers are included and the cabinet cost is low so the system cost isn't too bad. I don't know where else you can get the combination of size, efficiency, power handling and frequency range for the money. If you'd rather trade off bass for smaller size, Hawthorne has a 10" driver that will work in a very small baffle.

Re: Re: Big sound in a small enclosure
I still keep meaning to listen to some of those proac's, they do seem nice but they are bit expensice for something I will be moving around a lot, and possibly get damaged...
I'm not really too bothered about the bass below 60Hz, basically I want somethings that's pretty portable but still has plenty of spl.
I know it's a comprise, but I think there has to be a line drawn somewhere as I don't want to haul around a labhorn everywhere i go! I forgot to mention I use my amp6 on batteries and mains, depending on where I am... Right now it wired up to 2 x midi hi fi speakers that I have gaffer taped together... They are 6 ohms, and sound ok, but I'm just looking for something that will beat them in terms sql for a similar size. I'm guessing between 1 - 2 sq ft would be nice.
Basically I'm after the most amount of sql from a certain size box...

Ok a lot of that went over my head, but I've thought about just having a single mono bi-amped channel. I could use op-amps to sum the stereo signal, then each one channel for midbass and the other for highs. Basically I'm aiming for spl over sq, so I intend for it to be like a "baby pa system" or something like that.sreten said:Hi,
Probably active variable EQ for baffle step depending in placement
and an active 6th order vented alignment to maximise bass output.
Both can be arranged by thevmaniplation of the power ampliers
inputs and feedback loops, i.e. treating it as a large op-amplifier.
I know.gtforme00 said:

They do seem very good, I'd probably go for the 10" version... I'll have a look into these drivers.lousymusician said:
