real Subwoofer for Griff 10' or 12'
Discussion
Has anyone any suggestion to fit high end audio subwoofer with deep structure in a Griffith ?
I see two places :
either on the parcel shelf (in an enclosure) but I would prefer not to sacrify it. Have somebody tried this solution ? If we built a curvaceous enclosure , why not.
either in the pannel separating the cabin from the trunck but in this case, the sub has to work in an infinite baffle configuration.
Do you see other places in the car ?
Have you any suggestion regarding the best subwoofer for this car ?
For this instance, I have Audiom 6 for the mid + Focal TLR for the tweeter but I seriously miss bass.
After trying Aliante from Phase Linear (slim structure) by not convinced (fast but not warm deep enough) I was seduced by the 10' W7 from JL.
I really like the sound (deep and fast) but you know the problem because the deep structure....
I am an audiophile enthusiast but I prefer not to sacrify the TVR design.
I have contacted a guy from Genesis car audio in the UK who had a TVR.
He suggests using a 6 x 9 speaker.

"We have a 6 x 9 sub which is better suited to installation in the boot.
These are usually supplied in pairs and one can be fitted each side wherethe air vent is situated.
The 6 x 9 woofers are designed as a proper sub and will reproduce down to
40Hz with low distortion. I had a single free air mounted 8" in my griff as
the 6x9's had not been developed at that point.
This worked well and provided good levels of bass for my music taste. The 6
x 9 was originally developed for the new Mini but has found applications in
a number of cars where there is no space for a woofer box.
In the Mini the frequency response is within +/- 3dB to 40Hz. Below this it
rolls off at 12dB/ octave. The Griff has a smaller cabin so you may get bass
extension at lower frequencies when the roof is on, and similar performance
to the Mini when the roof is off.
The bass in the Mini is very fast and musical and this is helped by the subs
being as close as the front speakers to your ears so there is no time delay.
The same situation would apply in the Griff." Unquote.
Thanks for your help.

Corin Denton has posted a similar question on the General TVR gassing forum, she also sounds like she knows her stuff along with a few others by the sound of the replies - take a look.
I will be very interested if I can get hold of a pair of sub-woofer type speakers to go in the rear bulk head - my local audio shop could only give me big 170w mid-ranges, which sound pretty good, but not compared to the 450w bass thump that I get in my every day car!

For what its worth my Chim has two 7x10 Kenwoods in the rear bulkhead. Bass is ample (they are less than a foot from your head after all). Yes, that says 7x10 - like a 6x9 only bigger! (and yes, my amp does go up to 11 before the Spinal Tap jokes start 
)
I did consider a subwoofer, and was going to have an enclosure made to fit into the cubbyhole behind the passenger seat, but to get the right volume the seat would have to have been pushed forward a couple of inches. Not really fair when the battery already eats into the legroom!
I guess thinking about it I could fit a couple of extra 7x10's into the cubbies, but that would be more of the same rather than chest collapsing sub woofer frequencies.
I have seen a Chim with a subwoofer enclosure built onto the parcel shelf (it was at a Team Central track day at Donnington back in 1997, not seen it since). Personally I didn't think it made much perceptible difference over my setup - but ICE is pretty subjective so your opinions might differ.
My only bugbear with the ICE I have is that in normal driving my right knee rests against the door speaker (Alpine DD) and muffles the sound somewhat. I'd like to fit 6x9's into the doors as well to minimize that and pull the sound stage forwards a little (though my Pioneer KEH8400RW head has a mode to emphasise the fronts and filter mostly bass to the rears which is useful in that respect).
In my wilder fantasies I have wondered if there might be enough room under the dash somewhere to fit a sub, but I've never summoned the courage to try lifting the dash to check. I'd imagine not.

I reckon it would be hard to put a twelve foot subwoofer in any car...

Genesis make some of the very finest car audio amps on the market - I didn't know they made speaker units, though?
On a related note, I just threw my 8" sub out of the Saab (used to reside in the center console which was made to be a 0.35 cu ft. sub enclosure) and went for a pair of 6.5" Görlich drivers (very very expensive, used by the German Genesis representants in several award winning cars) in MDF/fibreglass kick panel builds. I must say with music CD's I don't feel like I sacrificed any bass, and the sound quality is steets ahead of the former set up.
I suppose this configuration (only the Görlichs and a pair of Vifa/Scan Speak tweeters, driven by one Genesis SA30 in bridged mode per channel) wouldn't do with "Boom Your Woofers" kind of CD's or action movie DVD's - but that goes for the former 8" sub, too...

Thanks for your comments.
Can we possibly use the front wheel despite of the battery ?
or can we made a hole in the parcel shelf. Is there space available below the parcel shelf ? Perhaps, this last question is stupid ?
As far as mid are concerned, I have seen the Görlich in Germany but unfortunately, the dealer have not allowed me to test them.Are they really superior to the others ? What do they have of so particular ? Is the difference in price justified ?
Yes ,Genesis made speakers, in particular new GENESIS 10 and 12 inch sub. According to the German representative, that will work with the GÖRLICH speakers. This woofers are released 14 days ago and the results seems excellent

I had a 10" sub woofer in the back of Chimaera - fitted to the vertical fibreglass section between the cabin and the boot.
I don't understand a word of the original post but I can say that with the sub woofer using the boot for resonance (if thats the right term) the bass completely drowned out the front speakers at anything other than town driving speeds and the whole car shook.

Only got a couple of hours listening to them, but based on that (they're the 'older' VK 160 version that I had the chance to buy at a slightly lower price, BTW) I would say it is. The beauty of the design is that when properly installed, there are no tonal flaws that need correction with passive crossover elements - in fact, mine run directly from the amp with no filtering whatsoever, and only an MKP condenser for a 6 dB/octave filter on the tweeters!
The Görlichs do offer an extremely high resolution over an astonishingly wide frequency band - spent rather longer 're-discovering' some of my favourite CD tracks than I originally planned for
. The high price of the units is relativated by the way they enable you to greatly simplify the system design - these 6.5" units are faster and cleaner in the midrange than even the best 4"s I know, whilst at the same time being as strong and articulated in the low frequency range as a pair of dedicated 6.5" 'kickbass' drivers.Just going through the same process with my 98 Griff.
The best my installer could do was offer to put 2x 8 inch Focal subs in the rear (replacing the air vents) in a free air config with an amp mounted in the boot between them.
That is just the start of a $7500 Aus upgrade which I can't afford right now. I'm interested if anyone has managed to fit a 12" or similar.....
Why? I know I will sound like a w*nker, but my other car has a single 15" sub, and my home system has 6x 12" subs... I love my bass, but I don't subject other people to it.
Answers anyone?
