Default CSS FR125S

What about the CSS FR125S in a U shaped open baffle or an aperiodic enclosure?

I find this project at parts express quite interesting. You don't notice at first how small these speakers are, but they are only 8" high, 5" wide, and 6" deep!

http://www.partsexpress.com/projects...ive/index.html

My only concern is *if* I look at the fr graph correctly, they have VERY LOW sensitivity, but I guess you can't have everything (small enclosure, 100Hz bass extension, and high effiency).

I am watching this thread very closly as I have a keen interest in this very thing! Although I don't mind going larger than the bose cubes, I do want something small, and stylish.

Currently I own Klipsch Quintets, which are stylish, but I desire a product that currently doesn't exist: Small stylish, decent sounding speakers with a wide dispersion center channel. I can't find this product anywhere, so I am considering turning to DIY, even though I have ZERO DIY experience, so I am very interested in the end product here!

I think you can get a better looking and sounding than the bxxe sub/sat for under $600.

I would check out the satellites that Mirage sells in there Omnistat line.

I have the Omnistats Micros, which are small and stylish. They are on very cool stands but can be wall mounted. They blow the doors of the bxxx sats because of the firing pattern. Tehy are dramatically 3-D sounding. They are not as accurate as a ProAc or similiar
overpriced 2-way, but I respond better to space and image than I do sheer linear accuracy.


As for the DIY sub..
You can build a sub with a kit to your liking. I like the Sonatube designs, but I would check out the Bill Fitzmaurice Autotuba (10" version).

Other satellite options are the ball shaped steel enclosures. I like the idea of concept. As for DIY, I wonder how one can get cast steel spheres with a hole cut out? Orb Audio, Anthony Gallo are well-known, but even Morel is jumping on that bandwagon.

I only mention the commercial speakers alternatives two the cubes and boring, large 2-ways.

The only problem I see with the Tang Band and other FR speaks are the very low power ratings. Of course, I have not heard anyone complaine, perhaps becasue they are using tube amps or something.

How are these for Bose beaters? To my ear they are better not to mention you can buy them on ebay for $15+/- each. I've got a set that I'm going to build some ELF 1.0 type cabinets for. My daughter is getting a nice sounding home theater setup for her bedroom. Will use Billfitsmaurice.com Tuba18 for the low end.

Actually, those look like very good Bose-beaters... if we're talking about sound quality.

I recently got to hear a pair of those at a friend's dorm room, and with the subwoofer I found them to be surprisingly neutral and dynamic. It may have been a slightly different set- but those logitec computer speakers have so much performance for the size and price that it makes Bose seem silly, and almost (but not even close! ) makes me re-think DIY for places where my girlfriend objects on aesthetic grounds.

Even more recently I visited the Bose store and listened to a lot of their systems. I don't have time to re-read this thread- but what the heck are people trying to beat?!? Sound quality? Easy! Making something smaller? That would be a set of headphones. The main thing they have going for them is a remote control.

Interesting that the Logitech system is THX certified but the Bose system isn't.

Default Not DIY, but still nice...

This may have been posted before. I don't know, since I haven't read the entire thread. Also, it's not DIY. But certainly a cheap and decent-sound-for-a-few-bucks kind of solution. Or it might help you to another idea.

Logitech X-230. They're originally PC or laptop speakers. They don't have very much power, nor sofa-shaking bass, but sound pretty darn good for the money. It's a 2.1 system for about 90 Euro's or maybe even less. A friend of mine has 'em hooked up to a standard laptop soundcard. So if you were to connect them to the output of a cd-player, you'd get a pretty nice, low budget-low effort solution. Try them out at your local computer store...

Edit: Uhmmm... Forget this post... You're trying to Really Seriously kick some Bose Butt. The afore mentioned logitech system isn't up to that task. It sounds good, really. But beating Bose Acoustimass? No...

First of all it is a DIY site.

The logitech's could beat bose but probably need another(larger) enclosure to benefit from the speakers capacity. Most full range Tangbands don't like too small boxes if you want them to get low to match the sub.

Nevertheless, maybe not a bose beater because it is not intended for living room use but for desktop use. Actually I'm designing them for my laptop and yes, the little copper tupe is an integrated stereo class D amp (amp3, 41Hz). I will use a modified M-audio usb soundcard to drive them and a tiny sub is in the design stage.

Don't know of the quality yet but I hope to beat most of the little computerspeakers out there.

The double walls of the cup's will be filled with bitumes and or silicones and the inner side will be covered with thick felt.

I'm showing it here because it might give ideas for designs with a high WAF.
