bigevilman Posted August 3, 2019 Share Posted August 3, 2019 Morning all I've recently got a old Eden D115 (non tweeter model). Its the model before the current D115xlt - it has a small circular port at the back. I came to play it and the speaker has completely gone. The original speaker was eden ec1560f (of April 1999 vintage). Has anyone got any recommendations for a suitable replacement speaker? Need an 8ohm model so i can use it with my 210.

chris_b Posted August 3, 2019 Share Posted August 3, 2019 (edited) Define "gone"! What drivers does your 210 use? Call these guys and find out if you can get the driver reconed. http://www.wembleyloudspeaker.com/ If the whole driver needs replacing then Eminence, B&C and Faital Pro would be on my list.

bigevilman Posted August 3, 2019 Author Share Posted August 3, 2019 Cone is stiff and smells burnt, and no resistance across the driver - practically no volume coming out, and when cranked goes distorted...no louder than a laptop speaker! The 210 I would say are factory standards...tbh I haven't pulled them out. I believe they're pre-Marshall takeover. Quote Link to comment Share on other sites More sharing options...
Balcro Posted August 3, 2019 Share Posted August 3, 2019 Good morning Joe, As it sounds like a total loss, you'll need to give the forum some measurements:- the cabinet external height, width & depth. Then measure the diameter of the port at the back. Do that and then get back to us here. From that we can give you the best advice. Quote Link to comment Share on other sites More sharing options...

Also worth including the port length (you may need to adjust that to suit a replacement driver, of course). Quote Link to comment Share on other sites More sharing options...
Balcro Posted August 3, 2019 Share Posted August 3, 2019 Hi DanDare, Agreed, yes. I understand your comment, but in this case and at this stage all you need are the externals from which you deduct 18mm per panel with a small extra allowance for the front baffle recess. It's simpler for the OP rather than breaking out the screwdrivers etc. As winISD auto-calculates port length from a given port diameter, the existing port will have to be accepted as part of the calculations. I don't expect the final advice will give a 100% solution, but it could be 95% plus. PM to bigevilman. Quote Link to comment Share on other sites More sharing options...
bigevilman Posted August 4, 2019 Author Share Posted August 4, 2019 Morning all Dimensions are 565mm height x 565mm width x 460mm depth. Port is 40mm up from bottom, with port 130mm in diameter. Hope this helps Cheers Quote Link to comment Share on other sites More sharing options...
bigevilman Posted August 4, 2019 Author Share Posted August 4, 2019 And internal port length is 195mm Quote Link to comment Share on other sites More sharing options...
Balcro Posted August 4, 2019 Share Posted August 4, 2019 (edited) I've tested a number of 15 inch bass drivers suitable to work in a cabinet that has a volume of about 108 litres. The best fit is the FANE Sovereign Pro 15 600LF. 220 watts all the way down to 32Hz. At that level of input it's blasting out 120dB!! https://www.fane-international.com/view-product/SOVEREIGN-15-600LF#tab-1 Close to that is a FAITAL-PRO 15 PR400. A neodymium magnet speaker. A full 185w down to 33Hz. At that input level it's putting out just under 119dB!! https://faitalpro.com/en/products/LF_Loudspeakers/product_details/index.php?id=101060100 The CELESTION PULSE 15 works similarly but has a lot less power handling @ 119watts down to 33Hz. Even at this input level, the sound output is about 117dB! https://celestion.com/product/158/pulse15/ I don't know if you're going to like this, but all of these are around £140-00 and all have a different (but classic) power handling dip (from their nominal rating) between 45-100Hz. These result are somewhat academic as the sound levels produced are huge, as is the headroom these units provide. If anyone else has alternative drivers that are cheaper, please feel free to add.

Balcro Posted August 4, 2019 Share Posted August 4, 2019 (edited) Some specimen FANE Sovereign graphs for frequency response & power handling. The Faital Pro is similar. Edited August 4, 2019 by Balcro Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted August 4, 2019 Share Posted August 4, 2019 The power handling chart has limited value, as power alone doesn't reveal maximum SPL capability. By the same token the transfer function magnitude chart doesn't reveal sensitivity. IMO the chart order of importance is SPL, Maximum SPL, Impedance, Rear Port air velocity and then Maximum Power. The primary use of Maximum Power is to plug that value into the Signal Source window, then check the Rear Port air velocity to see if it's no higher than 20 within the intended pass band.

Balcro Posted August 4, 2019 Share Posted August 4, 2019 Hello Bill, You and I obviously have different philosophies when it comes to using winISD. I start from a point where there is a fairly even balance from approx 80 - 250Hz then let the other details fall into place. In this case, graphs are "specimen graphs" the SPL is listed in the text (Post from 3hrs ago) (for 140 watt input). Putting the input up to 220Watts (eg. for the FANE) only achieves another 2 dB and yes, the rear port air velocity is still OK within the passband. The second graph is there just to illustrate the point about the dip in power handling for the benefit of the OP. Balcro Quote Link to comment Share on other sites More sharing options...

Cheers for this Balcro. I assume the Sovereign 400lf wont match the cab? Only asking as that's more readily available, and I probably will never need the full 600 watts!

Phil Starr Posted August 6, 2019 Share Posted August 6, 2019 The Fane wouldn't be a good choice anyway anything LF is designed to work with a tweeter and the roll off in frequency is likely to be too low to make a successful single driver cab.

Dan Dare Posted August 6, 2019 Share Posted August 6, 2019 (edited) This looks good - http://www.precision-devices.com/Product-Details/PD154. If you're prepared to spend Faital money, has to be worth a look. I'm a bit surprised Precision Devices drivers aren't more widely used as instrument speakers. They appear to be known mainly in the PA world. Very high quality and made in Yorkshire. Edited August 6, 2019 by Dan Dare Quote Link to comment Share on other sites More sharing options...

Great service, likely to be cheaper than a replacement and you end with a speaker that was designed to work in that cab. Quote Link to comment Share on other sites More sharing options...
