Car Components in Home Speaker?

[Stewart]

I've recently removed a bunch of my car audio stuff and I have a set of high end polk components (SR 6500's) and was wondering if there was something inherently bad about putting driver's designed for car audio into a home audio speaker. I'm thinking about building a set of smaller speakers with these. I love the sq from them in my car and figured I shouldn't let them go to waste. Here's a link to the specs http://www.polkaudio.com/downloads/w...ers/sr6500.pdf
It's the last page in the pdf. Thanks for the help.

Hi,

The short answer is they are not suitable for box speakers.

They would possibly work in a decent sized open baffle + low bass driver.

If I were to say build a speaker box with no back it seems as though that would be the same as putting them in a car door, i.e. infinite baffle. Does that seem like it would work?

Definitly. Open back would give good results. I wouldn't hesitate to use these for home audio.
Also would work well in a 60 litre vented box, give an F3 of around 28 Hz. Very worth doing.

Greets!

Look good in a TL or MLTL too.

Hi,

OK. The longer answer is they need a very large box in relation to
the driver size. The crossover must be reworked due to various
cabinet effects and free space, not half space mounting.

An open backed box will have no bass.

60L litre enclosure for an 11L Vas driver ? stupid ........
(all tunings of said 60L will have horrible uncontrolled bass)

Starting off with a 60Hz Fs driver ?
Not a particular good idea unless a subwoofer is involved.

Starting off with a 0.65 Qts driver ?
Not a good idea full stop for normal box speakers.

The Polks are designed for purpose and no doubt they work well
when used for that purpose. The short answer is still they are
not suitable for the described application, a small box speaker.

Using car speakers in home application would depend on the
driver TS parameters. Most car speakers are 4 ohm (or lower!) keep that in mind, can your amp handle them?
I think car drivers would work nicely in an in-wall application though.

Hi,

Yes. Without reworking the crossover :

In wall (flush) mounting would work. Also a large open baffle.

The realm of home speakers is new to me. I really got into headphones for a while and car audio was the next step. So as far as home speakers go it's new territory. I haven't checked the amp in my receiver yet, but I've entertained the idea of using a converter to just power what was my car audio amp. I splurged for a nice audison amp (my car got totalled which is why I was forced to take my stuff out) and it sounded amazing in my car, so that was the sound I fell in love with. With that in mind, the speakers are 4 ohms, so nothing too weird to drive, but none the less I feel as though I'll get better sound quality withe car amp than my Yahama receiver.

Anyways, as far as re-working the crossover, I did buy them as components so there is a passive crossover that I assume is tuned for open baffle. Like I said this is my first dappling in diy home audio, but I really enjoyed installing the car stuff. I had the drivers in an 05 mustang whic had 8 inch subs in the door but I made an mdf ring to allow the 6.5 inch woofers to fit. The subs were in a small enclosure so I drilled a ton of holes in the back of it to simulate an open baffle. I was new to it all so I had them in there for a while w/o the holes (i.e. sealed) and while it sounded fine, it did seem a bit muffled. The holes definitelely helped to bring out the spectacular soundstage that I love about this set.

So my questions... tl? mltl? f3? Half space mounting? Sorry for the questions but I just am not familliar with it all. I've toyed around with some speaker design programs, but after inputting the driver specs the box they come up with is about the size of any bookshelf box, which after reading everyone's advice sounds like its way too small.

Wall mounting is beyond what I have in mind, as far as complexity goes, but what I want to do is to be able to use these speakers now, untill in another year or two I get them back into a car. Despite that I have no qualms about putting the time and effort into creating the right mounting solution for them. The drivers have a suprising amount of bass; I have entertained the idea of buying an internal amp for the sub I also took out (Saes Lotus 12 inch) but am perfectly happy with just the components. I do not listen to much rap so my needs wouldn't necessarily require a sub, but obviously it would never hurt. Like I said earlier the strengths of this set is an amazing tweeter which provides clarity and the imaging is top notch as well.

So, sorry if I'm rambling, but with the above in mind I've heard a number of different suggestions and untill I start toying with it all myself I guess I wont be able to decide, but I guess it comes down to a complete open baffle or large box in relation to the driver size. Any advice with the above in mind?

so is it better to just not put a box?
