4” full range speakers and IKEA bowls

Recommended Posts

Some time ago I came to own a pair of Audible Physics RG100/6 full/wide range drivers.

These are the 4” 6 Ohm version and will comfortably and very ably play from about 150Hz to 20kHz.

 

I’ve been spending a little time building enclosures for these. I very much like what spherical enclosures do. I’ve been using various AP 3” drivers in small sphere enclosures in my car and have been very happy with the results.

Anyway, I digress.

 

I purchased 4 bamboo bowls from IKEA and have been working on getting them to make quality ported enclosures.

 

This is where I am at as far as progress this afternoon;

They have a 36mm circular ply spine at the join and constrained layer damping treatment. The internal volume is now about 3-4L courtesy of expanding foam spray. The port is 32x170mm for some boost around c70Hz.

 

I’ve ordered some spikes for them to sit on a table stand for now but I’d like to put them onto dedicated stands eventually.

 

I’ve also got some brass hardware and flared ports;

And I’ll be using Nordost speaker cables - 2Flat (white) inside the speakers and Flatline4 Gold (copper) for amp to speakers.

I’d wanted a small tube integrated to power these but I’m very much liking the Cyrus amps I have in my main system so I may keep an eye out for a Cyrus amp/DAC instead on the used market.

Super clever idea and application @Winno I bet they end up sounding pretty good.

 

Be sure to post more pics and your thoughts on the finished result.

Seen the Ikea bowl idea a few times. Wouldn't mind having a go at it one day.

Love the pillar speakers, how did you make those ones?

i love seeing wood used beyond typical box sections

used as domes really gives it an interesting old world but futuristic vibe

The ones in my car were CNC machined in Germany to my drawings. They were AU$450 which is pricey but, they were going to cost me more to have done locally.
