Sony SA-W303 Subwoofer

I was kidding - don't worry about it.

I wouldn't want to be the one paying their electricity bills, that's for sure.

Put a 50Hz sine through it (or better yet, a play it at tuning frequency to avoid excursion problems) at full power. Measure the voltage across the speaker, and measure it's impedance. From there, you can work out power.

I've found 50W to be quite loud through my sub, so I don't understand why some people need kilowatts to get their subs working properly.

unlucky me...no Testing Tools...ill Just Gestimate.

the Sony AMP is better than alot of Commercial Low wattage ones ive heard before...it never Distorted Obnoxiously like the ones from Durabrand and such did...

but i Already ****** the Amp Up...dont know if ill be able to fix it...im Better off just Grabbing the Dayton 70 Watter.

form109, I actually have this exact sub that was given to me by a neighbor, and before I tear it apart, how deep was the 6 1/2" driver? I'm thinking about replacing the driver with something a little better.

The Driver is 3.7 Inches Deep.

Measured With a Tape Measure.

Thanks! I think I'll put this speaker in it:
Parts-Express.comayton DC160S-8 6-1/2" Classic Shielded Woofer | woofer dc160s-8 6-1/2" woofer midbass shielded woofer dayton dayton audio dayton loudspeaker

What do you guys think?

You might want to measure the ohm load of the factory speaker before selecting a replacement. I doubt Sony put an 8 ohm sub in the enclosure.

a Dayton Classic Woofer doesnt seem like a Sub Driver....id Go For a Tangband Instead...i Put a Daliquist Buyout Sub in mine...probably lost a little output since the Woofer is 12 Ohms.

The SA-W303 Enclosure isnt Terribly Good either...tuned Rather High...and Chuffs Excessively Around the Tuning Frequency.

i never did measure the Ohm Rating on the Original Woofer...but the Amp did get Rather Warm Driving my 8" Tangband (which is 4 Ohms)

 

[SnoopKatt]

Hm, so if the amp is 4 Ohms, then a 4 Ohm sub should work?

 

[BP1Fanatic]

Yes!

 

[SnoopKatt]

In that case, it appears these are my possibilities:
Parts-Express.com:Tang Band W6-1139SI 6-1/2" Subwoofer | subwoofer 6" subwoofer neodynium subwoofer tangband tb speakers tangband-22008
Parts-Express.comeerless 835004 SDS 6-1/2" Woofer 4 Ohm | Peerless P835004 835004 SDS woofer 6-1/2" Woofer 4 Ohm woofer bass mid midbass mtm coated cone 2-way tymphany peerlessBuy050109 Symphony of Savings Peerless070109 npa00453 TymVifPeerBuyouts

I'm leaning towards the second one just because of price lol. What do you guys think?

And thanks for all the help so far btw!

 

[BP1Fanatic]

Go with the Tang Band W6-1139SI 6-1/2" Subwoofer for the 13mm xmax!

 

[SnoopKatt]

That is very true...good reviews too, and someone dropped it in a very similar Sony sub and got very good results, according to the reviews (SA-W305).

 

[BP1Fanatic]

Looks like Sony did use an 8 ohm speaker. Specifications are at 6 ohm.

I'm sceptical about the idea of more Xmax is better.

Why would shaking the cabinet around more help?

Anyway...
The Subwoofer Conundrum

 

[BP1Fanatic]

The other speaker only has 3mm xmax and both speakers are more than likely not designed for Sony's enclosure. You got 4 times more room for error with 13mm!

 

[chris661]

... and it would also require maybe 4x the power to get to the same level. When you've got limited power, efficiency is a must.

Perhaps someone should run a sim.

Nice link

I see your point now!
Tang Bang = 83dB's.
Peerless = 89dB's.
The Tang Bang needs twice the amp power to reach the Peerless' spl.
