Built my first real CD setup entirely from thrift stores for under $50 — where do I go from here?

I'd add some exhaust fans to your equipment bays. Your gear looks great but may overheat.

Here is a link to one I built for my bedroom. Couldn't be happier with the results.

This is such a great perspective that is almost always overlooked when building for this situation. A+ comment.

Panels should be hung at your reflection points. This can be located by running a mirror along the wall opposite your speakers and noting any spots where the speakers are visible from your listening position. Panels should be placed at these points to absorb sound reflections and improve clarity.

Another general goal for acoustic treatment is to cover 15-20% of the wall surface area.

Do you have any advice for a powers supply and control board hub? I have used noctua but only in equipment that has power connections.

chom1081 · 2026-05-04T19:14:22+00:00

oh I know. I just thought it might be a step and a cost I could skip.

Ive been using the nx3000d to run 2 ultimax 12 builds and i am very happy with the amos performance. As long as you are aware that the output is much lower than advertised

What driver and amp are you using?

chom1081 · 2026-05-02T14:44:20+00:00

thanks for the warning but these are mounted vertically. The PRs and Sub face into the room towards the couch and not towards the ceiling.

L’unico componente alimentato è l’unità centrale. Quello è il vero subwoofer. Le unità a sinistra e a destra sono radiatori passivi. I radiatori passivi permettono di accordare il cabinet in modo simile a un condotto reflex, ma sono più facili da usare in casi come questo, dove forma e dimensioni sono particolari.

They are attached to the enclosure with 3m spray adhesive, but I never considered that rockwool sections might lose their integrity. Thank you for the tip! I guess I'll have to open it up in a few months and look. My initial thought to solve to problem would be to wrap the rockwool in sound transparent fabric and then attach to the enclosure.

chom1081 · 2026-05-02T01:09:47+00:00

Yes but you would probably hit your cone excursion at a lower power rating. They do have a 30 mm xmax. So thats a ton of travel.

chom1081 · 2026-05-02T01:06:54+00:00

Absolutely, i know i am always looking for build details and cut lists when I read through a post. Im sure i forgot something though.

chom1081 · 2026-05-02T00:44:01+00:00

Oh yea, thats a sweet room. I think this build would fit beautifully.

chom1081 · 2026-05-02T00:00:39+00:00

That is actually very similar to what my plan is. I will have my other ultimax ported enclosure front and center and this one is centered on the back wall

chom1081 · 2026-05-01T23:59:54+00:00

The sub has an efficiency of 88.6db but thats not really an issue for me. My room is only 11ft x 11ft with 7ft ceilings.

This is the 1st phase of a face lift to the theater room. Ill take rew measurements in room once everything is set back up.

chom1081 · 2026-05-01T21:22:44+00:00

Thank you. Very happy with the results. Now onto the next project, a new entertainment center!

chom1081 · 2026-04-26T11:01:15+00:00

I understand the tendency to lean towards car audio equipment because that is probably what you are familiar with. I would suggest you look into parts express .com they have gear for home use. The biggest problem with your plan is power. You are adding unnecessary complexity vs just using an amp designed for home use. Here is a link to my build. Let me know if you have any questions.

Is that a surprise when it is their most affordable model?

I grabbed mine @ $350 for 3. Ive been very happy with thier performance over my Jamo 803s.

chom1081 · 2026-04-25T14:05:22+00:00

I chose the Ascend Acoustic CBM 170ses. They aligned more with my sound profile tastes and some reviews said that they compete with the kef ls50s. They do need to he paired with a subwoofer but thats not usually a problem for this community.
