Alpine SXE-5725S 2 Way 5 x 7 Speakers: Amazon.co.uk: Electronics
Here you go
I am no sound enthusiast but I would recommend them. Bass makes the door vibrate against your leg so I guess they are working properly
The 2 tabs at the widest side of the oval just have to be bent round or cut off and then they are a straight fit with the existing screws and cover etc.
Looks like they were on offer when I got them!! Now I feel good
I researched into replacing my front speakers and found a couple of people recommending the 5" x 7" Alpine SXE-5725S as being an easy upgrade. I knew I would need to cut off or bend away the fixing tabs at the 7" end and this is true, but I immediately found out the tabs projecting beyond the oval at the 5" end also need to be cut off, no big deal as I happen to have a pair of tin snips. This done it was possible to mount the speakers.
Unfortunately doing this effectively blocked off the grille mounting holes, making a simple reassembly impossible, all four of the grille clips actually touched the speaker near the rim. I removed the spring clips from the grilles and by using Sellotape Outdoor Sticky Fixers on the end of the mounting lugs was able to fix the grilles in place. [note that if with a 5" x 7" speaker the upper & lower clips can't be used, with a circular 5¼" speaker the same should apply, though possibly the side clips could be used though the adaptor plate would probably need trimming at the sides]
A couple of days later I decided to look into plugging the now unused mounting clip holes, and pulled one of the speaker grilles off. I found that the sticky pads had stuck onto the speaker sealing strip just by the rim of the speaker, unfortunately this is of soft cardboard which is fine for its intended use but not suitable for sticking something to, the cardboard had been partly pulled away and no longer usable for fixing the grilles to. I had to clear out all the cardboard and glue in some small blocks at the grille fixing points. It was obvious that attaching the sticky pads to the new blocks was more sensible. The sticky pads need to be about level with the top of the speaker soft rubber ring.
The original speakers are definitely not 5" x 7", but are larger than 6" x 4". The overall size including the mounting is 5" x 7", the mounting holes spacing is 112 x 112mm. Looking on ebay I could not find any speakers with suitably spaced fixing holes.
It turned out to be a far bigger job than I anticipated, but the sound from the new speakers is SO
much better than from the originals. Only trouble of course is that it now shows up how poor the other speakers are.
