I've been away from this thread for a long time, and it's great see that Perpendicular is still in the Minx camp. After all, it was his early enthusiasm and experimentation with the Minx that gave this thread it's existence and endurance.

I'm curious if there are any new BMR or Minx developments in the last year or so.

What Perpendicular says about the Minx "base modules" is interesting. But the point ien2 makes about the SVS's
ability to render deep bass at the same time allowing for a very high crossover makes a good argument for the use of that sub.

Hello,

I hope no minds me asking a n00b question about the Minx Min line-up. This thread seems to be the best place to ask a question (and I searched through it already). I have a smallish room (9.5'x11.5' with 8' ceilings) so space is a premium. I am going to go with the x301 subwoofer but I am wondering about what combination of Minx Min 12/22 to use. I am thinking of using a single Min 22 for the center channel and then use 6 more 12s for a 7.1 setup. Is this reasonable or should I go all 12s all around? I understand that the 22s provide more low end, but would not the x301 provide plenty of that?

Thank you

As the experts on this thread have not yet answered, my opinion based on general knowledge of satellites, surround and audio, is to build a sytem with Min 22s...at the very least for the front L-C-R, and preferably all around.

You want robustness and sonic weight all around, and the second (non BMR) driver in the 22s will definitely provide that. I wouldn't put all the heavy-lifting on the bass module.

Hi Andrew,

Would like to check if the listening room is totally enclosed based on the dimensions given? If so, the floor area is less than 110 sq. ft. and total volume is less than 900 cu. ft.

That's a small listening room. You can do much better than using the X301 and for such a small room volume a pair of subs will be more beneficial as the room modes are at a higher frequency. There's been good feedback on SVS SB1000 sub woofer with Minx owners and I suspect other Internet Direct (ID) sub companies would be just as good as SVS.

As taichi4 advised, it would be better to go with Min22 for the LCR and Min12 for the surrounds.

Hello, I have just upgraded my amp to a Denon AVRX2200W. I have existing Monitor Audio Bronze Series speakers (old model). I want to add 2 front height speakers to my setup and have been looking at the Cambridge Aidio Minx series. I am unsure out of the M12 and M22 which to plump for. Is the M22 going to be overkill for just front atmos height speakers? Is it worth paying twice the price for these over the M12s?

Any help will be appreciated. Thanks

It will depend on how high in frequency your sub(s) can play to. If your sub(s) can go up to 200Hz, either the Min12 or Min22 will be fine. If you have a single sub, there might be some localization issues.

Edit: For a 5.1.2 Atmos/DTS:X speaker configuration, the general recommendation is for the ceiling speakers to be Top Middle and not Front Height. With your Denon AVR-X2200W, the back surround speakers are going to be used for the 5.1.2 setup.

You would be better off with the Min22, which has a minimum frequency of 120Hz. The crossover frequency to your Monitor Audio BRW10 sub can be thus set to 120Hz, which is the limitation of the sub's frequency response.

The Min12 lowest frequency response is 150Hz.

Thanks, all ordered and received today. Just got to work out the best placement for Atmos in my setup.

Hi nick,

Wasn't sure about the about the model number of the B&K sub, so is it the Platium P12300-SB unit?

The Min22 needs to crossover to the sub at a high frequency (around 120Hz). Looks like the highest frequency on Platium P12300-SB is 120Hz so it could be a close match with the Min22. Try setting the filter swtich to Out/LFE and let the Pioneer VSX-930 receiver to determine what the appropriate in room frequency crossover is.

I would be very surprised if the Min22 can go as low as 80Hz in the room - are you sure about this? You might want to do a frequency sweep of the Min22 in your room to determine if this is correct. Check at which frequency the Min22 starts to roll off and see where the -3dB point is.

Thanks steveting99

Yep, i have the Platium P12300-SB
I will do a sweep of the room tonight. I think the default was set to 80mhz so this will change once i know what i am doing.

Thanks for your post, it makes a bit more sense with why i am setting the cross over and for what reason. Im still getting to grips with a decent sub and system

I will post back with an update

Thanks
Nick

Hi chaps
I would like to apologies in advance for the lack of understanding in home audio

So i spent a few hours setting the sub and speakers up. I went through the automatic mic set up which came with the AMP and it went through 10 mins or so of sound checks.

After the crossover freq was automatically set to 150, looking at the spec of the speakers the max is 125 for the MINX22 so the next setting was 100 so i moved it down to that for the crossover freq, is that ok?

I need a bit of basic help now.
All these dials. what do they mean. I have tried moving them to get an idea but i am struggling to understand what Phase/Freq/Lo and High level gain mean

Currently i have them all in the middle with low and high near the max

Also, i made a schoolboy error when cabling the room. I only left a spare 2 core cable near the sub so i am a single cable short for the High Level input. is that correct? i need 3 cores to wire the high level input in?


Thanks
Nick

After being absent for a while, I see there is still some confusion regarding the Minx satellite speakers.

The whole idea of the second driver (or BMR) added to the Min 22 which is absent with a Min 12 is to allow a bit more mid-bass bloom which will produce a more fuller sound. Not to allow the speaker to play a lower frequency range. You can only derive so much out of a 2 1/4" driver, no matter what the crossover design of the speaker is. Therefore, I do not recommend a crossover setting lower than 140-150 Hz for either the Min 12 or Min 22 (this recommendation equates to previous models too). If the subwoofer you are using does not play cleanly up to 150 Hz, you need another sub. Otherwise, you will creature a gap in the 120-150 Hz range.

As far as using additional speakers for effects with codecs such as Dolby Atmos, DTS:X, use the Min 12 as there shouldn't be any benefit using the larger Min 22 unless in larger spaces.

Getting back to what I stated earlier about subwoofers and the Minx satellite speakers. I'm not saying that you cannot create a satisfying experience using a subwoofer other than the Minx X series. You may need to work harder at getting it to blend properly, etc.

Btw, my recommendation for movies and tv shows is using three Min 22 up front as a minimum. If you listen to a lot of surround sound (4.0 and 5.1) music like I do and watch a lot of music videos, using the Min 22 for your rear/side surround channels is mandatory.

Leave it at 150Hz as that is what the in room frequency response is for the Min22 as reported by your pre/pro/receiver. As recommended by Perpendicular in the posts above, the recommended crossover frequency is 150Hz for the Min22.

Go to page 4 of the Platium P12300-SB sub owner's manual which shows how to connect from your pre/pro/receiver to the sub. Note that the switch the for the Filter Bypass Switch needs to be in the Out position. Your pre/pro/receiver will manage the bass frequencies on the low level inputs.

Set the Phase to 0 degree. Set frequency to 120Hz.

On the Lo Level gain, initially set to 10 o'clock position and measure the dB level at the Main Listening Position (MLP) by sending a test signal into one of the channels. Is it 75dB/85dB (Depending if one is using the LFE channel or bass management on the other channels)? Adjust the Lo Level gain until the MLP reads 75dB/85dB.

Then redo the auto-calibration.

By the way what type of pre/pro/receiver do you have? I have some experience on the Denon/Marantz gear and believe Perpendicular is pretty knowledgeable with Pioneer gear. If you have another vendor for your pre/pro/receiver, then asking for some help in the appropriate owner's thread is a good way to go.

Marantz SR-7009, Oppo BPD-93, MTV 7000D, aTV, Harmony Home Control remote, KEF E301+T101, MiniDSP (2x4)+(10x10HD)+(DDRC-88A), Emotiva 2xXPA-5 (Gen2), Rythmik 2xF12G+2xF8, HiMedia Q16, LG 55EC9300.

Cambridge Audio does list the frequency response of the Min 22 as 120 hz to 20khz, vs 150 hz to 20 khz for the Min 12.

So the Min 22 does reach deeper in the bass.

Why don't you come over, have a listen and hear for yourself. I can set them up for you. Otherwise, the answer to that question was already answered.

I'm looking for something to replace the NHT 2.5i/1.5/AC-1 speakers I've been using in my 7.2 system for many years. I've been plowing through most of the posts in this thread and I'm very impressed with what I've read about the Min 22.

Unfortunately the crossover point issue affects me. I've seen the many posts discussing what is ideal and particularly Perpendicular's strong recommendation for 150-200hz despite a 120hz lower freq spec. I totally get the 150hz-minimum recommendation, but other components in my system don't give me a 150hz option. The highest crossover point in my Lexicon MC-12B EQ surround processor is 120hz, and the two compact M&K VX-100 subs I plan on putting back into service probably should be crossed-over at 125hz.

I'm trying to decide how much to concern I should have about this. The Lexicon has excellent room EQ processing that I think should adequately compensate for any modest Min 22 frequency dip between 150hz and 120hz, and besides, I would actually be willing to sacrifice a tad of performance for the much greater WAF that the Min 22's would provide over the NHT's. Despite what might be ideal, I'm thinking in my case this 120hz vs 150hz setting shouldn't be a deal breaker with the Lexicon's room EQ compensation.

I'm just wondering if anyone else might be happily operating a set of Min 21/22 speakers at 120hz (with or without a processor that has room EQ to flatten the dip).
