Building my Overnight Sensations (Speaker kit)

So I got my kit and it was well packaged by Erich from DIY Sound Group.

Put together the sides and baffle using clamps and wood glue.

I cut some board for the crossover base 3″ x 4 1/4″ (small enough to fit through the woofer opening) and attached a schematic to the board that was on one of the forum posts.

I drilled holes in the crossover boards and waiting for the cabinets to dry and have some lunch.

test fit the components.  They fit!

Hot glued the crossover parts – tomorrow I solder it up.  I put on leads.  Do not know if I will need them but it is easier once they are on.

Sanded the cabinets with 60  then 220 grit with a circular hand sander.  I hand sanded the bevels of the baffles.  I primed the cabinets with some Rustolium grey primer.  Kind of a shame as the wood grain is pretty nice.

I also got the crossovers ready to solder. I am not looking forward to this as I would prefer an etched board but never the less. Maybe I can do some vacuuming or rake leaves.

Solder of Crossover is complete. I must thank Soundslike on Parts Express Tech Talk forum for the CAD drawings and connections. He even included the mirror image for wiring the back board. This made it easy. Hope I can show it.

I tested them and they seem to work well so far.

I then hot glued the crossovers on the back to protect from shorting. I need to give the cabinets another coat of primer after a light sanding and wait for another 24 hours. I hate waiting.

I had to put a zip tie on one coil as I dropped the crossover on the floor and it ripped off my paper backing I had on the front of the crossover.

Lost a point for neatness.

After sanding I painted with Rustolium Black Satin. I could not find another can of the grey primer I was using so I skipped a step.

Time for a Top Gear (UK) and off to bed.

….a day later….

Finally finished!

Glued in port tubes on the back then finished off cabinet.  Lots of glue everywhere.

Put in the crossovers and my fiberglass insulation with gloves on.

When wiring up the tweeter I needed to reverse the polarity as per the designers specs.

SHOWDOWN!!!!!

So how do they compare to my B&W DM 600 S3’s?  The B&W are of comparable size and have an MSRP of $350.

Well……..ummmm  pretty much the same.

I am driving my good stereo with Rotel power and preamp separates (@ 120 watts ) and a Rotel 1072 CD player.

At low to moderate volume I really like them both.

How do either compare to my Phase Tech 10.5 (MSRP $2,200)? – well they don’t but it is a different speaker meant to be driven hard.

Here is a look at the back panel.

It is really hard to compare speakers and explain how they sound.  To me either a speaker sounds good or it doesn’t.

Will I sell my B&W’s?…. maybe

Will I sell my Overnight Sensations – NO WAY!!!!!!!!!!!!!!
