Wozza_Lee Posted August 24, 2019 Share Posted August 24, 2019 I would be very interested in seeing a response plot of this at say 30* off axis to see. Link to comment Share on other sites More sharing options...
Wozza_Lee Posted August 24, 2019 Share Posted August 24, 2019 When I measure I would normally do at 0*, 15*, 30* and 45*.I would normalise my response (and then apply eq[emoji41])If you are considering maybe make the mids and Tweeter in the same box in a offset mtm set up with minimal spacing, it's not like the Tweeter needs a box anyway so it's essentially 'wasting space'...... It does look very nice though Link to comment Share on other sites More sharing options...

It does look very nice though Not really at this stage I have single drivers running -(WMT ) + 18" in each corner and I can not fault the system it sounds pretty good so no changes are to be made to this speakers very happy with the outcome. 2 Link to comment Share on other sites More sharing options...

jkn Posted January 11, 2020 Author Share Posted January 11, 2020 I have also made some progress towards my Apogee OB project at this stage I'm not sure about the shape of the front baffle yet but will be using Apogee ribbon 6.5" mid/bass and 15" bass . So far I have made just temporally baffle just to measure the ribbons 4 Link to comment Share on other sites More sharing options...

They are usable from +-600 up I believe there are some good bass drivers which will make it 2 way speakers And yes mid drivers is a option I will try several options before making final OB speaker set . PHL 6.5" mid/bass is also in OB and crossing at 250Hz >750Hz. I'm also thinking to place the mid/midrange next to the ribbon (centre) so the ribbon/mid are in ear height.

davewantsmoore Posted January 21, 2020 Share Posted January 21, 2020 Quote hey are usable from +-600 What makes you say this? Is it just the frequency response? (roll off) .... Don't be fooled by that. It is a dipole with the natural extra rolloff. In theory, the rolloff is actually the area where you WANT to use the driver (where it has constant directivity, below the dipole peak). However, what WILL limit where they can be used is excursion. There is no point using them flat out down to 200Hz (for example) if that's going to cause too much distortion at your playback levels. 6 hours ago, jkn said: I'm also thinking to place the mid/midrange next to the ribbon (centre) so the ribbon/mid are in ear height. Tough one to call. I wouldn't. ... but I'd also, use a larger "mid" driver.... and use a narrower baffle for the ribbon.... So I'd just be tellig you "do the whole thing different" .... so don't listen to me, LOL Link to comment Share on other sites More sharing options...

Funny thing is that when I asked 10 people for potential OB baffle design/ideas, I did get 10 completely different opinions/designs so it is hard to follow/choose one. In regards my idea to lower the Ribbon to ear height, placing the mid/bass next to the ribbon in the centre was after seeing Apogee Centaurus slant 6 which has Mid/bass next to the ribbon > nevertheless I'm trying to do 3 way and Centaurus is 2 way, so anyway I will have to try it and see how it goes. STILL wondering if it would be better to have 15"on axis with the 6.5"mid/bass or with the Ribbon (using Centaurus speaker arrangement) On 21/01/2020 at 11:15 AM, davewantsmoore said: How do they sound?! I think it has great potential as they are already sounding pretty good in temporally baffle. Edited January 25, 2020 by jkn Link to comment Share on other sites More sharing options...

Hi Murrmax I have always use the 15" PHL down to 90Hz only in 4 way where the volts takes over . Nevertheless I have burned some resistors (my fault )on my DEQX4 so I"m sending my deqx to Sydney for repair. However I'm thinking to try (over the weekend) 3 way only as I do have another 2 deqx3 which I would like to test anyway, So back to your question I will set couple of profiles one as 3 way >with 15" PHL sealed and also >one as 15" ported to see how it all performs I will post the measurements if you interested J Link to comment Share on other sites More sharing options...

Yes it does I'm currently listening to the ported option and it does sound very good.I believe this bass box was designed by Pat (war audio) and he did really good job. Note: I could also re - position the speakers to reduce the suck out - 30-50Hz that is If I was settling on 3 way only. Anyway very good outcome I'll be working on final OB design using these drivers J 1 Link to comment Share on other sites More sharing options...

Again you will get better result if you use: 1)MTW design 2)MT in one box only (sealed) don’t worry about the volume much 10-15l 3)Tweeter and mid as close as possible (1 box) 4) 3 way woofer in separate box -ported (calculated the box height feet and so on so you end up with the tweeter at your ear height) For design have a look at the internet or ask some guys at DIY audio.com) Basically you need box volume number and size of the port s j Link to comment Share on other sites More sharing options...
