REL T1 vs Dynaudio Sub300

[glyg]

BK sub seems like a real bargain but I can only buy one online as nobody sells BK here. This will surely be a problem when it comes to warranty.

I have to consider T1 (PR) and Dynaudio SB300 (ported).
Unfortunately, I dun have a full grasp of all the graphical illustrations in the tests especially on the power compression, Group delay and THD components graphs.

Although I would be considering a SB300 (10"), I would assume the results should be quite similar to the SUB500 (12") except with less deep bass and headroom.

Will somebody please help comment in greater details on the T1 and Sub500 tests. The good and the bad, regardless of price. I can get the T1 and the SB300 at about the same price, which is a better sub and more worth? This sub will go with my Dynaudio 72se floortander for music and movies. Please help. A million thanks

Unless you're in Finland, then the whole point of BK subs is that they are an online only operation.

Why? I'm not aware of anyone who hasn't had a warranty issue resolved their satisfaction, even when there has been an indication of the product being used by a complete head banger. For a company reliant on the online community for the success of it's product line, you wouldn't last long if you didn't treat such issues this way.

You'll find that your links don't work because they are to a competing English language forum. However, based on those results as the SUB500 only offers similar, or worse performance than the T-1; There is therefore no reason to suppose that the SUB300 will come close to either, so if it's a choice of SUB300 v T-1, I'd take the T-1.

However the BK XLS-300/PR makes a case for itself as a direct performance (and design) equivalent to the T-1 for considerably less money. Depending on size constraints, a Monolith for the same money would blow any sub yet mentioned out of the water.

From the graphs, the SB500 is ruler flat up to 100db. I thought it was impressive. The T1 frequency response is hump shaped, I'm worried it will sound boomy at that particular frequency ?

Comparing the following specs, I thought SB500 was impressive. What do you think ?

T1 (10"):
Pros :
- plays comparatively louder
- power compression flat at all bandwidths and loudness. good

Cons :
- frequency response hump shape curve, boomy bass ?
- THD slightly lost out, reaches 10% at 28hz
- group delay slight lost out

SB500 (12"):
Pros :
- ruler flat frequency response, more accurate , quality bass ?
- THD slightly better, 10% at 25hz
- group delay slight better

Cons :
- a 12" sub does not play as loud as a 10" PR sub ? strange.
- lost out on power compression tests, deteriorates at higher decibels and lower frequencies.

I'm no expert, so can you please help check thru whether my conclusion is correct. Please correct me if I am wrong.
You're definite T1 really better than the sub500 ?
Please comment, thanks.

I have also looked at the popular B&W PV1 and REL Stampede tests, both are 5 star pedigree touted by magaiznes, I thought the results were disastrous compared to the SB500 and T1. I very nearly bought a Stampede last time. Would have regretted it if I did. Specs dun lie.

Hang on a second We're going from trying to extrapolate and compare a SUB300 (which is a £900 sub discounted) to a £600 REL T-1, onto comparing with the SUB500 which is a £1200 sub.

Whilst I appreciate it's the only Dynaudio with a measured performance published, you can't assume the smaller sub will just be a smaller version. Yes, the 500 will go lower and louder, but it's not as simple as that; It'll do it with less distortion too at all volumes.

So, whilst comparing the T-1 and SUB500 is very interesting, you're not proposing to buy a 500 and I've already stated why I think the T-1 is the better of the two subs you are considering.

Yes, the REL does have a slightly odd top end roll off, but this wouldn't be much of an issue. The -3dB point is still up at 114Hz and typical crossovers will kick in below that at 80Hz (-3dB). By the time you throw in all the other hash the room can contribute, I wouldn't worry too much.

As regarding it sounding boomy, that would take a much narrower lump in the response to dominate the overall sound. By the time you factor in potential room gain beneath you rooms lower mode, I'd expect the RELs response to get propped up to nearer flat and perform quite nicely down into the low 20Hz region, which is very good for a small sub.

Thanks Russ,
You're right, I may be completely wrong to assume the smaller and cheaper SUB300 would have similar characteristics as the SUB500 albeit not as low and loud.

I was amazed how flat that frequency response was on the sub500 and thought if sub300 is just as flat, I might go for it. THD was impressive too.

Don't forget the Netherlands where RA Subs are selling them (and where you can listen to different BK Subs....)
