Home theatre - sub + fullranges question!

[bezobraznia]

Thank You for Your opinions...
I suppose that FE127 will be good enough in quality , but i'm afraid that will not gain enough sound power for me... I never listen it and I don't know...
On the other side.. Soon I expecting my new (ebay vintage) Philips 9710M8 drivers - 97db/w/m ... I don't know what enclosure will be the best for them yet... but if i've made it ok, then I can use my Visaton BG20 (92 db/w/m) Voight Pipe's (from link below) for front channels and the other three for surround and center...
btw, for center I was thinking about two drivers in paralel maybe including tweeter between, or one driver with two bass reflex ports, or maybe one driver in mini double horn 😉 thats is good idea i think - double horn ... because i like symetric...
The most importand is ability of drivers fit in diferent volume enclosures ... or combine similar in sounding drivers that in the end i would have the same sensibility levels of all drivers in HT
From Cal Weldon in the first post i understand that spl of active subwoofer depends on level of plate amps on it, so sub is not problem... The overal ballance of 5 speakers is hard to balance, i think...

Around these parts it's:

Re: Re: My simple HT system

What is Jim Griffin JX92+G2si ? Did You mean EJJordans JX92?

Absolutely briliant ideas... I didn't hear any TB yet, but I've read somewhere in diy formums that TB is not as good as Fostex etc. that's because I was thinking about Fostex for HT. TB bamboo fiber look very cool btw

I have heard the Fostex 127, 167 and 207 in their horn loaded boxes. Actually I was only able to hear the speakers with grills on so have to believe what the sales person told me (I was not able to visually verify this) and they do some things (esp midrange) very very well but for a system that also has to do HT I think the JX92 would be a better bet. mated to the G2si (a la Griffin) you should get the HF extension you need. Besides the JX92 is quite well equipped to producebass down to 50Hz which allows you some flexibiltiy with the sub's integration.

Of the 3" - 5" fullrange drivers I've tried, there are 3 drivers I like: Fostex FF85K (3"), FX120 (4.5") and TB W4-1320SB (4").

The FX120 has a more balanced sound, but is much more expensive. B]

The FX120 is comparable in price to the JX92 and comes with a formidable reputation. It is another driver worth looking at.

I have a very good 5.2 system in Portugal, and a 3 times cheaper 2.1 in Latvia...

With 2 open baffle fullrange speakers I get as much "surround" sound as with 5 closed boxes, even the helicopter on Pink Floyd flies behind me, and it sounds better...

Also, do closed box subwoofers, no reflex, no passive, they wont sound as goos and will be harder to integrate, as they will have peaks and deaps in the port and radiator ressonance areas...

Just realized that I omitted the "it" in FWIW. Cal, thanks for the correction.

Ok, the choice will be between:
Fostex FE127E and Tangband W4-1320SC witch is the same like Tangband W4-1320SD. The price is almost the same.

Fostex: Fs: 70Hz, Tangbang: Fs: 75Hz
Fostex: 91dB/w/m, Tangbang: 89dB/w/m
Fostex power input: 15W, Tangbang power input: 25W
Fostex Vas: 9.9l , Tangbang Vas: 5.99l
SPL vs. Freq - almost the same, on table TB has better, but in real I don't know because I never listen these fullranges.

Will Fostex have the same sound pressure with 91db/w/m and 15W input like Tangbang with 89db/w/m and 25W input?

I don't know is Tangband W4-1320SC shielded like W4-1320SD.
If not than this will be the other problem, especialy for center channel. So if i choose TB, then i have to look for shielded similar to sounding of W4-1320, any ideas? Or maybe ideas for several TB for center channel, but shielded?

Thank You!

You won't want to put 15w or 25w into those drivers. Forget max power ratings -they're only there to tell you how much power you can pump into them before they disintigrate. In practice 3 - 5w should be perfectly sufficient.

FWIW, I'd go with the Fostex. Whisker more sensitivity, and as a rule, most people prefer them, sonically, to the TB units.

hi, i;m aiming for 2.1 also with jim's jx92s+ribbon, but what sub driver suitable for them, which jordan's are pretty fast

any suggestion?

 

[planet10]

but what sub driver suitable for them, which jordan's are pretty fast

I ahve not found a "sub" that works, to do a good job of integration you need something good up to at least 500k.

If these protos work with the FF85k they should work well with most... the SDX7 is not officially a sub, but the previous proto indicates that close to 20 is achievable (sealed with a touch of boost -- possible because of XBL2)

What was really startling was how extended the woofers alone run full range and listened to facing to the side were.

Hello,
I'm consider building home theatre speakers...
Topology that i choose is subwoofer + five channels i.e. 5.1
For soobwoofer i've choose two Peerless XLS10'' drivers. I think building one or two subwoofers with passive radiators in sealed 30l. The most question is for the other five channels.
I think about fullranges, maybe in small boxes... i really don't know. Maybe fostex, I like how they look with white cones, but what model will be suitable with XLS10 sub? I'm not sure about dependancy of SPL of front, back and center channels. For example for front speakers i may use FE207 dirvers , for rear - FE167, for center two FE 167 or FE127 drivers. Will i have to use recomended tweeters from Fostex for these drivers because except clear mid freqs i like clear high freqs too... Maybe other fullranges? I was thinking about EJJordans, but then i will exceed my budget, which is not exactly fixed btw... Anyway..
If any suggestions - You are welcome!
Thanks in advance!
Reggards!



p.s. If moderators consider that this thread is not for fullranges forum (because of more that two drivers construction, especialy including sub), then feel free moving in in another subforum. Thank You

I would go with 5 Aurasound NS3-8a fullrange drivers in small cubes such as these:

I have a pair of these drivers and for home theatre they will be much better than the FF85Ks as they will reach down to blend with the sub better.
