thanks again for your advice.

to be honest the "x-over" ended up quite complicated .I have no real measuring equipment except a free software frequency generator and my ear "lugs" There are 5 uf electrolytics (ugh) by-passed by sufflex small value c's, some resistors, some inductors in line with the 5" mid bass
I messed around with the values until i got what I thought was a smooth
sound. My wife says there too bright but since I,m 58 and my hearings
on the slippery slope thats to be expected.One of the benefits of audio
equipment ,as opposed to hifi is the addition of tone controls in my LEAK 2000 stereo receiver.So I cut the Hi-Frequency when she's
listening!! I think the problem I have left with the combination of these drivers is more to do with a hi-mid peak on the mid bass unit &
I should design a soft notch filter when I get around to it.In general
though ,the information retrieval capabilities and the bass extension for there size, for the paltry £20 per unit they cost me I,m well pleased.
I'd like to Know the details of your set-up using these monacor units.

The subs are already in use as it happens ,most people on the D.I.Y
audio forum warned me against trying this but I had some reasonably large inductors to limit the upper frequencies and the 12" speakers were already mounted under the stairs so they are not in any sort of near field as regards the stereo image. So there you have it a pseudo bass bin made out of part of the cottage , and 2 ,little speakers hanging in the corner of the living room. NOT hifi by any stretch of the imagination but all the frequencies seem to be present, upper-mids maybe too present!! but its still retrieving more info from sources than anything Ive had before.If i ever get divorced I may even find out what Hi-Fi sounds like! HA HA

Ive finally found out how to upload images so heres what all the
fuss is about.As you can see ive doctored the piezos inside and out and they sound O.K. to me but then I,m no golden eared hi-fi expert.
