Default Bedroom speakers

Hello all !

This is my second post here.

My son listen relaxation music for sleeping with a Disney dvd-tv combo. The TV is a tube and i don't like the flyback sound. Listen same frequency for a while can be damageable for hearing. And the sound is poor.

So i think about build two pair of micro monitor. (i have 2 child) Active speaker if possible. I will probably play music from MP3 (with 196 or 320kbps).

For master bedroom, i have a pair of Klipsch active computer speaker. Sound excellent for the purpose.

The speaker wattage can be very low.

I'm open to full range or two way configuration. The speaker must create a good illusion of image like waterfall, rain etc. The Klipsch and an panasonic portable cd player so it well.

My budget is very low. Each dollars is an over budget dollar so :P

Ok, the Klipsch can reach like 60Hz. I don't know how but i know i can't expect that with my project. 150hz and more will probably should ok.

I think is something different here. Some idea ?

Small, very small. It can be mini ceiling speaker something that fit in two to three inches whole in the ceiling.

Thank you all !

there is another thread talking about some surplus Stewart Screen 3" drivers at Meniscus -- they looked interesting. Couple that with one of the Q-Kit

Postage could well end up exceeding parts cost...

Meniscus charge between 63$ and 111$ of shipping !!! The total cost will be too high from there.

I live near enough of Solen (canada). I can pick-up stuff in person.

I see some HiVi Research mini full range and special price on Veravox small 3.5" full range too.

Something going wrong with Meniscus shipping calculator. The cost is so high ! I'm in canada... Anyway...

The Stewart Film Screen have good specs and excellent price (6$)

other idea ?

I can strongly recommend Zaph's design in Jacq's link above. I have these in my bedroom and they are surprisingly good. Of course, they are not active, however. Well worth the money, though. They do lack deep bass, but you don't notice that much.

If you have an existing small pair of boxes of 2 to 3 litres that you can salvage, even better. Stick a new baffle on the front and Bob's your uncle. I made mine somewhat smaller than Zaph but with the same 'crossover' (filter) and they are fine.

I will build two pair, one per room so i can try the both design !

Zaph project is well detailed and appear to sound good.

For the 3.5" Stewart Film Screen i have no idea of how to design the subwoofer. I need very low sound pressure so i can do some cheating to get more bass if i "boost" in with the amp. I can buy an cheap T-Amp on ebay with bass, treble, balance and volume control. Just plug the driver directly and adjust bass and treble with my tastes ? No crossover at all for save money.


Is it good ?

You might want to consider These . They're pretty small and very inexpensive.

Hey, they look great, Pete!

I can vouch for the sound of the Hi-Vi's, at least in the 3" of the Zaph creation. Surprisingly couth and realistic, especially nearfield. Nice mids, not really metallic sounding. Adequate highs, too, if you're not too critical about the n'th degree of shimmer on your cymbals. Note I only use them for FM radio from a 70's Pioneer tuner, so YMMV according to source. These cost me around AU$50 a pair, going for economy components.

Obviously Paul's creation would have more at both ends of the spectrum.

Today i cut the MDF for the Zaph B3S enclosure but now i have some hisitation.

Zaph don't look to like the sound of the speaker without subwoofer. Ceilling installation is not recommanded and th crossover seems to be difficult to adjust.

What about his "R2" resistor ? Can i replace it by a potentiometer ? If yes, which one ?
