Beginner advice

I found that $45 shiva kit at adireaudio

guess I forgot.

will the perf grill cause air turbulence from airflow?

[TimForman]

My experience was that since the driver fired down and I'm not in fear of rodents or misplaced feet I didn't need the grill. I already had 12 AWG speaker wire. Compare prices and make sure that you actually need everything in the kit.

 

[JoelTW]

Does Home Depot sell 12awg speaker wire by the foot? I can't remember seeing it but they probably do.

I thought the grill was for the port... I guess if you put it over the port it would make port noise

Do I have to use braces between the top and bottom end caps like some recommend, or just nail it in around the tube?

I think I found a great guide...has over 100 photos... the "Sonosub III" from Patman?? I think.

Tim, should I stuff it with polyfill in the 18" x 32" tube you recommended?

 

[TimForman]

Typically, in sonotube, you line the inside of the tube with batting (the stuff you make blankets out of) not loose polyfil. I struggled with it a bit but I had the wrong adhesive. Try to find the spray adhesive Pat used.

I was looking at the Blueprint 1201 that Frank linked to but it says $92.

Isn't the Shiva a better price:performance deal?

 

[TimForman]

I think you were looking at the 1001. The 1201 is good bang for the buck. If you're on a limited budget you can legitimately save $55 bucks and get decent performance. The Shiva will outperform it but it's up to you if you want to spend the money. If you go with the 1201 you may want to go with the 100 watt amp and save a little more money.

 

[Frank Carter]

I think you clicked the picture for the 1002, that costs $92(it looks like it goes with the 1201 text). Click the picture right above it or on the text for the 1201. I don't know much about them other than they are a respected brand by others here.

Comparing their Vd:

$125 Shiva MKIII = 1.52L
$70 BPD 1201 = 1.59L

 

[JoelTW]

I have a 18" diameter sonosube cut to 32" height...

I have a router but am missing the black plate that screws onto the bottom. I also need a circle jig (i think that screws on?).

I see.. the blueprint 1201 does look like it would fit me better. I don't really mind spending the extra $ for the shiva if it has better performance worth that extra $50?
