Replacement Front Speakers For 78 Series Landcruiser

I'm with Allan on pretty well all counts, as above.

I pulled out left side spkr on mine (2008) and it was lowest in range of the Fujitu TEN series.

..or see here "http://www.npsonline.com.au/shop/category/speakers-4-10cm"

..spkr wiring loom in mine is coverred in the 2007 'Cruiser manual available from 'SuperCheap store chain.

We all love our wagons but they are 'Blardy noisy. Do yourself and your partner a favor and fix the 'in cabin' noise first.

Rip out the front seats and Dynamat whole inside of front cab, and inside front doors, take your time, its a three day job.

One jumbo pack will do it. Buy the under bonnet kit too, cover all the engine bay areas not coverred by Toyota standard liner.

.. you will be amazed how good the Dynamat material is.

Spkr wireing loom on mine also runs back to rear doors.

..all of that said, to me Alan is on the money IMHO.

( The internal roll bar is a good idea too. I have three steel struts accross in mine, makes that point on cabin very rigid in case you pop the windscreen (or roll it) )

.. cheers

Thanks Convict, you have given me a bright idea...........

Been looking for a job to do on the Troopy whilst holed-up for the summer and Dynamat in the cab is the answer. Doors, floor & firewall.
Dynamat is pretty exxy but after searching I found it on eBay, in Australia, for around half the price of audio shops.

Just occurred to me that an alternative place to mount speakers in a Troopy is to install an overhead shelf above the windscreen using ply, MDF or similar, covered in vinyl or carpet. Then fit the speakers in each end of the shelf. The only problem will be that one speaker of the pair will be much closer to the ears than the other so will diminish the stereo effect.

Hi Allan

..two cents worth, suspect you will find spkr in doors
are a better local for good/better sound, just like pic below.
Big cavity seems to help.

Dynamat 'Extreme, ..do cab first, everywhere, wot u got
left divide between doors. U do not need to do all the door surface, do strips, like on Dynamat instuctions, it breaks up harmonic 'nodes'.

Too easy to do in door spkrs with door panels off. U can get 'clip together' plastic eyelets off the antenna people
for door-to-dash via way, and thread wire through 'heat
shrink' (ex Jaykar), measured against door in fully open
position, and the lot through eyelets, a touch of the hair drier, job will be solid, and possibly even water proof.

..cheers

Thanks Convict, I do have a fairly good understanding about speaker enclosures and sound in general. Agreed that speakers in car doors benefit from the door cavity although, unless that cavity is acoustically lined, there can be unwelcome reflections and resonances generated.
Certainly I would place a pad of something like carpet on the door inner surface directly behind the speaker.

Personally I dislike the sound coming from the direction of my feet but it may not bother others.

I have placed an eBay order for enough Dynamat to treat the doors and floor of my Troopy. All up $298 with free shipping. I would comment that this stuff is superior to simple closed-cell foam and similar. Dynamat is composed of butyl rubber which is mass loaded with barium sulphate or similar. It is this mass that absorbs the lower sound frequencies whilst being supported within the pliant rubber reduces retransmissions. Further, being attached to the steel panel it reduces resonant vibration of the panel. Simple foam helps but is nowhere near as effective as this Dynamite (or similar) material.
