REL strata III vs Spendor Sub 3, which to use with S3/5?


I have Spendor S3/5s and would like to find a subwoofer to use with them for both music and home theater. Judging by what I have read so far, the REL Strata III and the Spendor Sub 3 look like the leading contenders, and their design seems similar. Has anyone compared the two? Which one will mate better with the Spendor S3/5s? [It would seem that the Spendor subwoofer should, but Spendor is not known for subs and REL is.] Thanks for the help.

Replacing the power cord with something better on the Storm III will tighten up the bass. The Stratus probably sounds tighter on a quick comparison because it does not go as low, so it does not set off room effects as much. Each REL going up the line is an improvement over the one below it from my experience and from what I have read.

There was someone writing reviews on Audioreview.com that made the same comments about the Storm III and Stadium III not being as good as the Stratus III because of the port issue. I do not agree or believe it, especially considering they feel the Stratus III is a better sub than the Stadium III. But I guess everyone is entitled to their opinion. The Stratus is a great sub; but if you can swing the extra $500 for the Storm, I recommend you do so.


There are reviews on both the Storm III and Stratus III at www.hifichoice.co.uk ---- They liked the Stratus, but felt it did not go low enough. They rated the Storm III their favorite of all the subs they have encoutered. They are a mid-fi and budget audiophile magazine. Mostly stuff under $2000 per piece. I've always liked this magazine. They do not seem to kiss up to companies that advertise with them as some audio magazines do.

To answer one more point made by some comments, the Strata III has a crossover of 12 dB per octave, whereas the Sub3 has an 18 dB per octave slope. That makes it important to set the REL crossover at a lower number.
thanks for your comments and help
I am looking at the Storm III or the Stadium III. I would like to get 2 of them and hook them up in stereo right beside my 803N's. Are two Stadium's too much of a good thing? or even necessary?
I have two Stentors. I put off buying the second one for a long time because it seemed a ton of extra money for just more bass. Finnally I bought a second one and I was completely blown away.

It was more like replacing speaker cables then just adding a sub. Better imaging, better detail, better stereo seperation. Stereo subs helped in ways I never even imagined. The most suprising part is how much it cleaned the sound up.

Then theres the bass. WOW! Punch and clarity like I have never heard. Not only is this the best music set up I have heard but also the best home theater set up.

I would consider though buying one better model then two lower models. You can always add another one later!

From the specs, I don't think the Spendor goes as deep as the REL. I love Spendor speakers generally but I think the class act in sub's is REL.
