Default 1 day ghetto line array build < £200

Posting this because it was surprisingly successful.

The cones are cut to size with scissors after marking with a ballpoint resting on one of the driver boxes (which happened to be about the height of the bottom part that needs to be removed so the remaining top part has the right diameter to fit behind the driver).
Holes poked through the cones with a screwdriver.

Wires inserted and cut to length with scissors. Drivers are wired 3S2P to get nominal 6R impedance.

Drivers chained together with stainless steel plates and cable ties.

Wires soldered to drivers and binding posts.

Some damping material added into cones. I used some PVC anti slip mat from co-op.

Cones hot glued to drivers.

Suspended from ceiling hooks with speaker wire.

Sound is surprisingly good.

Edit: I thought they needed a sub but then I found the tone control on the little amp I was using and turned up the bass a bit.

Nice build, kiss principle. Pioneer TS-G1310F would be cheaper, construction like fostex Why not OB, car speakers have high qts and again cheaper, no box...

I tried with and without the cones. The cones definitely help a lot to get down further towards the bass frequencies.

I chose the 3 way drivers because they had a good rating on Amazon and the comments about sound quality were promising. I didn’t see the G1310F because I was searching for 4” drivers.

I added woofers (made from buckets, ballpoint pens and gorilla tape). The drivers for them shouldn’t be full range but it doesn’t matter because they are on a separate channel so I can use a LPF.

I added some cones in the external woofer buckets to reduce the resonance of the bottoms of the buckets. Seems to have tightened up the bass a bit. Sounds quite good now.

I stuck the cones into the buckets with carpet tape and put a layer of carpet tape between the buckets too to stop them rattling at high volume. Here’s a shot of the tapes, glue and one of the ballpoints I used to make the woofers.

I noticed that. Next time I’d put the woofer in the middle and make it a cross.
