hi
has anybody built wilmslow audio sm110 studio monitor, it uses a volt bm2500.4
bass mid , and a scanspeak d2905/9700.000 tweeter , in a 33L ported box wilmslow audio claim a 25hz bass extention ,but on the volt website for bm2500.4 they clam a 32L ported box gives -3db at 50hz . if anybody has built this kit or used this bass mid driver what was the bass extention like.
thanks.

Can you link to where you are getting your information. The Wilmslow page I can see for the SM110 says 55 litres and 30-30kHz without any limits. The Volt page I can see gives -3dB at 40Hz for a 45 litres reflex cabinet.
Although doable, I am not sure you will find many people suggesting a 10" woofer and a 1" flush mounted tweeter is a particularly good combination.

My experience of Wilmslow Audio has been very disappointing. I built the Prestige Platinums and they are not what they are cracked up to be.
hi andy
just checked wilmslow audio site and they have updated info since i spoke to them earlyer today.
what i want to build is 2 way floor standers up to about 60 -70 litre cabs .
i would like to design my own rather than do a kit.
i fancy using volt bm2500.4 and fountek neopro5i and crossing over at 1.5kh
to buy these drivers from wilmslow will cost £1139 with del and vat.
or i can get 2 volt bm2500.4 from falcon acoustics for£468 ,and ican get 2 fountek neo pro5i from team audio.fr for £299with del total cost for drivers £767. a saving of £372
over wilmslow price .with this saving i would build crossovers & cabs.
.i want a speaker that can play loud with low distortion good treble and bass into mid to high 20s.

what was problem with prestege was it cabnet vibrating as they dont have much bracing
on them large panels.
on them large panels.
A 10" driver and 1" dome flush mounted is not a particularly sensible combination but a very expensive 10" driver with a very expensive ribbon as a 2 way is looking unwise. However, some people want to do the best job that can be done with particular drivers regardless of being able to get better performance and cheaper by doing something else. This is fine. Others want to get the best performance given constraints like size and budget. This is also fine. If you want useful advice it would help to know the constraints.
Why are you looking for such a low bass extension from a 2 way?
Are subwoofers an option?
Floorstanding speakers of 70 litres or so with a budget of about £1000? That should get you 3 way speakers with 2x8" woofers, 5" midrange and 1" tweeter using standard range drivers. Or variations like a 12" woofer. Is this of interest?
at the moment i am using subwoofer but space is a bit cramped so has to go would like speakers with real bass .i have mourdaunt short performance 6 speakers but these sound light weight without sub.
cab and crossover less complicated for 2 way.
Your current speakers look better than what you are proposing.
Loud, deep, high quality bass comes from a set of subwoofers distributed throughout the room plus room treatment. Getting the main speakers to provide the lowest octaves looks like a step in the wrong direction. Replacing your current 4 way with a 2 way is without question a step in the wrong direction when it comes to performance.
You cannot have a pair of 2 way main speakers with a -3dB in the mid 20s and get reasonably high quality performance. Something like this is around the budget but is a 3 way, bigger than 70 litres but is likely to get somewhere near in terms of bass in real rooms.
Hi jbj1
Have you seen this thread?

I have heard a pair of these speakers and I feel sure they would provide the bass you seek, without a sub. Recommended.
cheers

Some people would disagree stating that fewer drivers are better than multiple ones.
Indeed but such recommendations are to do with the posters enthusiasms and interests and not what gives high performance in the real world. People are of course welcome to share that enthusiasm but reality will intrude should they ask the world to judge rather than others that share the same enthusiasm. Exotic audiophile cables are a good example of this. Single driver speaker enthusiasts are a less extreme example. If you think physics doesn't matter and they may be on to something then go and have a listen. The result for many, possibly most, is bafflement.
If you want bass into the 20s at decent volumes that means big woofer/s. If you want good high frequencies that means a small 1" or so tweeter preferably in a waveguide. Trying to directly join the two means a big change in directivity, a woofer in break up at the top end, an overstrained tweeter at the bottom end resulting in poor midrange performance. Adding a midrange driver sorts all this out which is why it is done for pretty much all high performance speakers with deep bass.
If you give up bass into the 20s then you can use a midwoofer or lots of midwoofers as suggested above. (I have not checked but having all those midwoofers working at frequencies that cross to the tweeter is not a good idea and so the lower woofers are likely to be turned off at high frequencies. Making it effectively a 3 way except it uses drivers that are not optimised for midrange and woofer duty.) This is popular and can work reasonably well and potentially very well with subwoofers making a 3 way again. However the OP knows he does not want to do this. He wants the deep bass back he had with his subwoofer.
For your budget you could build multiple smaller sub woofers. These may be easier to locate/hide around the room?
I can't see how it would be possible to reach deep bass performance with
a driver like Volt 2500.4. I suggest going either with PA or HiFi drivers
all the way.
This one I'd consider for the task:
H1659-08 U22REX/P-SL
In a 70 lit ported box, F3=32Hz; F6=28 Hz; F10=25 Hz and about 15W
of power for reaching Xmax and 100 dB/1m is what you can expect.
Looks like you are going to have to accept some compromises. A pair of 8" drivers instead of your current pair of 6.5" drivers would give you close to a 12" woofer performance in a package a few inches wider than your current speakers. Here is an example although if deep bass is a priority a pair of aluminium woofers tuned low to give a gentle roll-off is likely to be preferable. Or even out-and-out 8" subwoofers with a 6.5" midwoofer crossed low around 200 Hz or so. You could then put the woofers close to the floor and the midrange high just under the tweeter to avoid floor bounce. With standard range drivers (£75 woofer/subwoofer, £50 midrange and £35 tweeter) this should fit the budget of £1000. Of course, it is going to take a lot of time and effort if it is to perform well.
. . . and then they want / need a sub-woofer 😉
I write as someone who has a pair of Quad ESL-57s but occasionally when listening to Bach, Mendelssohn or Franck I feel I am missing out on low organ notes.
Violin does sound good though 🙂
But then I can probably no longer hear the high notes anyhow.
Ahhh, what the hell - enjoy what you enjoy!
Indeed. A 2 way electrostatic like the ESL-57 needs a subwoofer to make a 3 way if high quality sound reproduction in the home is the objective.
If one accepts an almost unacceptably small sweet spot then a good quality large panel plus woofer could probably be classified as a high quality 2 way. Perhaps a floor to ceiling line array of 2" drivers designed for the job plus woofer/subwoofer? It is hard work avoiding at least a 3 way if high quality sound reproduction is a requirement. If price is a concern it is possibly unavoidable.
very intresting looking driver says intended for reflex or transmission line.
transmission line may be way to go. building cab would be no problem woodwork wise. only problem would be would be working out dimensions of line etc. i know 1/4 wave for this driver is about 2.96m but amount of stuffing can afect lenth also.
here is some speakers using 2 volt b2500.4 and i think tweeters are fountek neo pro5i http://www.robsonacoustics.co.uk/collections/voltaireIV/
