Wiim Ultra with REL T/x series subwoofers

[Promso]

Hi Guys!
I bought Wiim Ultra and pair of active speakers with integrated amps.
Think to order now REL T7X subwoofer, but I found in manual that they highly recommend to connect the sub as an inactive speaker for best quality. Screenshot from manual attached.

Anyone tried to connect such sub to Wiim Ultra? Which connection method you use? How is the quality?

I’m thinking that maybe it will not perform as well as it should if just connecting through sub out on Wiim and then maybe not even worth to overpay for this nicely sounding sub and just order something a bit cheaper.

My god what a bargain are these BK subs And guys, they ship over all Europe! Could you recommend me some specific model instead of T7X Rel, I mean I want more quality that house shaking base. Room is ~40m2. But for such a price I can just order the most powerfull one Just a bit afraid that biggest driver will not be so quick to pair with my small speakers..

They have three types

sealed box
passive radiator
ported

XLS400 is the best sealed
Monolith + is the best ported

Gemini/ double gem is the budget model with cheaper driver.

A couple of XLS200 should be fine for music, generally I like subs for stereo systems to be barely noticeable, but for movies I like it to be like a force 11 magnitude earthquake.

Can I actually connect 2 subs to Wiim Ultra?

LOL Rel think using high level means their sub is passive? haha bunch of muppets.

Where do they say that? I think that was a misinterpretation by the OP.

an elegant idea would be to be able to dedicate a pro (or a mini) in management peq l/r , filtering, timing etc..just in stereo ana output to two stereo sub

Technically you can (using a Y splitter cable), but it would be dual mono, not stereo subs. Such a setup can still be helpful to better couple the subs to the room, but it's probably over the top. Stereo subs would be yet another story, but as mentioned by @canard there currently is no WiiM product supporting stereo subs.

My personal recommendation would be the XLS300-FF as I prefer front firing subs for music. Unlike the T/7x it's a sealed design (as mentioned by @rccarguy), features a very high quality Peerless driver and offers 300 Watts RMS power (50% more than the T/7x). And it's even more compact. The former XLS200 and the current XLS300 are almost identical, the only difference being the plate amp. The XLS300 uses the same 300 W plate amp as the P12-300SB instead of the slightly older 275 W version found in the XLS200.

But, no matter what I think, this ...

Yeah, the team is already looking into that .

Hi everybody,

I was reading your thread and I also have the Wiim Pro Plus (I'm fascinated by its performance, in general) connected to some active speakers (Edifier S2000MKIII). I'm very satisfied with the set, but perhaps the main aspect to improve is the subwoofers...

Considering that, indeed, the Wiim Pro Plus does not have a subwoofer output, what do you think about splitting the analog signal that comes out via RCA from the Wiim Pro Plus? Is it really efficient or is the signal lost, negatively affecting the signal that reaches the active speakers?

Thanks in advance !!

i known the small Dayton box for a long time..seems obvious that it is an idea to explore...a good reconversion for a Wiim pro etc.

Everyone is different, everyone's set up is different, and every room is different.

Very generally - and there are a whole heap of caveats to enter here - if your sub set up is good enough to be non-directional to your ears, then stereo subs aren't really necessary. If you have one sub in the corner, and it doesn't sound like it's coming from the corner, then 2 subs, with one approximately where each speaker is, your subs aren't really offering you 'stereo' in the traditional sense.

Now, caveats. Firstly, two subs will offer you more of a chance of more even bass. But if your bass is even already due to your positioning and EQ, that's a non-issue. Secondly, two subs should also mean less distortion. But again, if you're not getting audible distortion, then it's a non-issue. This may well depend on room size, seating distance, and thus typical listening level.

I'm very fortunate. My room is small, I sit in nearfield, and don't listen at the ear-bleeding levels some appear to like. So the actual output levels of my speakers and sub are relatively low. In addition, I've managed to get my sub's FR very level, and at a point where I can't detect its location. In other words, I'm fine with one sub.

But others might, no sorry will be different.

The Rel t7x is a sealed subwoofer with a passive down firing driver.
I had a BKxls400 and it is a great value powerful subwoofer, but personally I think the rel subwoofer is less coloured than the bk, it's more neutral sounding, I didn't have a t7 but did have a T9x.
I am not trying to put down the BK subwoofers as they are superb, I had mine for many years and the support from BK is awesome.

Yes. That's technically the same as ported or bass reflex. It doesn't work like a sealed sub, even if REL are trying to hide it (like many other manufacturers.

Passive radiators obviously cannot suffer from port noise, of course. Mounting a PR down firing is a very questionable design choice, though. The suspension will wear out sooner.

Yeah they usually try and say ported = slow, therefore a PR is a ported = slow as well, so just they say sealed with PR

Was trying to call them today, answered some lady and I straightforward asked if she can advice me which sub to choose, she pretended that she don't hear me anymore called again in a sec, no answer sent them email.

And what do you think about that newest model:

Platinum P12300-SB

Looks like a same concept as in Rel tx, with passive driver at the bottom, maybe it would be even more suitable for music?

I really would love that effect that you dont feel that sub is in the room, but instead it looks like you have much bigger speakers.

 

[harkpabst]

I have been talking on the phone to Olive in the past, no problem.

The XLS series is using higher quality drivers. And it's sealed (like in really sealed, not marketing sealed). I like that better for music, but others will surely disagree.

Maybe just not fully back after holidays period

But will you clearly feel that sub is in the room with XLS? Or in other words is it more like SVS or JL Audio type sub where you at once feel their presence in the room or more like Rel or Rythmik Audio where they create a feeling that you have bigger speaker?

 

[gazza1101]

There is a BK400 on AV forums if that's the way you decide to go

Personally I cannot assign a typical sound to a particular brand. Most are making vastly different types of subs for different use cases and taste of their customers.

In theory, a vented enclosure (explicitly including Helmholtz resonators using passive radiators) can extend to lower frequcies and thus their are typicall associated with home theater use and more ooomph. In practice, most subwoofer enclosures are way to small to allow for a classically correct bass reflex alignment. Unlike sealed enclosures, the properties of a reflex enclosure doesn't change gradually and linearly when changing the volume and tuning frequency. Instead, only a finite number of discrete alignments exist, which result in low ripple linear response. Most sealed sub enclosures are way.to small to provide deep and linear bass response, too.

Manufacturers overcome these problems the same way in either case, by applying lots or EQ. There are limits to this approach imposed by electrical power handling (read: overheating), cone excursion or more precisely voicecoil excursion (distortion and finally physical damage), acceptable group delay and so on.

Summary: There probably is a certain tendency to make vented subs to suit those who are after maximum impression and seals subs for those who want to avoid boom at any cost. Both concepts can be tailored into any direction, when done right, so the above is not a hard and sound rule.

On top of that, WiiM gives you EQ and in particular PEQ to tailor the sound to your liking. There's no magic in subwoofers that make you "feel their presence" other than sound pressure level at low frequencies.

Hello people, this is exactly the topic I have been looking for))

I have been really considering to purchase a quality subwoofer for my small room (11*14feet). I mostly listen to EDM where there is a lot of bass. But I don’t like boomy overwhelming bass, but rather quick and tight one.

My setup is as follows:

Wiim Ultra -> Musical Fidelity M3si -> Buchardt P300

I am new into this hobby, and while I really enjoy the sound of my system. I feel that I could do with a little bit more in the lower range. Also, the room correction measurements on my Wiim Ultra show that there is a significant dip at 40-60hz, and the room correction can’t really fix that.

I have been leaning towards the REL T5x solely on the reviews on YouTube, however after reading this thread I am now interested also in the BK subs. Which model would you recommend considering my room size and musical taste?

Also, will I be able to fix the issue with the dip at 40-60hz if I get a sub and set the crossover point in the Wiim app at 60hz?

Last one) can you still run the RC on the Wiim Ultra with a connected sub?

Thank you,

Sherzod
