Those aluminum mini speakers

[Cal Weldon]

I have a set of Sound Barrier: Concord speakers that need new drivers.

Here is the tweeter section. It measures 3" X 2" on the bolt pattern.

and here is the woofer section. It is 4 1/2" on the bolts. It also has the rounded square basket. It seems like an OK little project.

Cabinets have an internal of 1.7 litres.

Are there replacement parts worth considering?

Am I just looking too hard for something to do in the DIY deparment?

Those look a LOT like Realistic Minimus 7's. Very similar cabinet, and measurements. I know there was some talk a while ago about refurbing a set of Minimus's's's's's''' but I don't know if we ever actually got past spray painting the cabinets...

Either way, it's something worth looking for.

Hi HiggityHank,

That's what I was thinking. When I was younger, these were one of the 7's competition. These didn't sound quite as good. I would like them to sound even better than the 7's.
Anyone have ideas? I be quite happy to make these a great little set of speakers. ie: come up with some decent coin, if the cabinets are worth it.

Any help is good help,

Cal

The shape of the driver is like the first link.
frame shape
This driver looks OK but my box is 1.7 litres or just over 100 cubic inches.
4 1/2 woofer
What else is out there?
I wouldn't mind some good drivers in an ugly box. you know, for the surprise factor.

why don't you try something from Tang Band?, something like these http://www.tb-speaker.com/detail/1208_03/w4-616s.asp

Thanks Bartek,
That looks pretty good. Will that give me some decent bass in such a small box?

It should, it's about the same size as an elf1.5 from css which use a pair of similiar TB drivers, they have a good reputation. Also you can make a plate to cover up the tweeter hole and run that driver full range as it's meant to. Should image great. If those cabs don't work out that well you'll still have a pair of great, inexpensive drivers to play with in DIY cabinets. Good luck.

I was actually thinking of using the tweeter plate with the hole from where the the dome was and adding a small port, approx 1" inside diameter.

A wee little ported full range.

Are there other drivers that might fit the bill and handle a little more power I wonder? I wouldn't mind seeing these things handle some real gusto, but first and foremost I would like them to sound good in such a small enclosure. Full range or two way. In fact I might just use the XO in the cabinet with a full range to attenuate the mids if needed.

The port is a good idea. It would give you a little more low end you're looking for. Try modelling this set up in win isd...maybe I'll get to it first, watching a flick with wife right now.
