Sorry for the same old post.
Working on my 'spiraling upgrade' to my 335.
Same old question:
What would be the best replacement speakers for under seat?

Thanks for the help I have received already.

Using processor (3sixty.2), all amped with Arc KS, EQ SWS now.

Looking for exclusively 100-250hz. And some power handling.
Clean, musical, powerful, and with punch.

Heard of the MB Quartz, Gladen, Jehnert, Morel, Kicker, and Match.

Aside from the Morel and Kicker, I have never heard any of these other speakers.

Any help appreciated.

Thanks,

Johnny

again sorry for the :

Jehnert 8" XE200.
Get in touch with Don (6spdcoupe on these forums) for a set. Not going to get much better unless you want to spend big $$. I recall them playing down to 40hz comfortably as well so you could get away without a true "sub" for a bit if you haven't gotten one yet.

+1 I've high passed them at 30hz before with no problems.

VP had German Maestros in a type three build
The subjective comment was the smoothness of the Jehbert
with the Bass of the SWS-8 . I think there about twice as
much as the Jehnerts though and they require some cutting on the
enclosures.

Yeah. Mauestros are a custom job not a drop in. Not even worth bringing up

Especially since he only needs them for midbass. I still want to try those Phoenix gold subs if they can handle what they say they should be good.

Awesome Guys...
Thanks for the replies!

So now I am between the Jehnert and Gladen...

Rainbow intelligent line 8 ". Very good underseat speakers. can go as low as 40hz, handle more than 150w. I think the Gladens, Match, MB quarts are quite similar

But they do not play with authority below 50hz.
And clip easily if you play them beyond their limits.

Gladen is perfect balance b/w earthquakes and Jehnerts.

PS: fitted sws-8, Jehnerts, Gladen, Ion, morels and Dynaudio.
After trying all these, I still use sws-8!
Not perfect for midbass but excellent for my needs.

They have some output I don't try to use them like a real sub I have 2 of those. I just had it like that temporarily. Since they are 4 ohms they can only get 75watts from my xd600/6 without clipping and since I leave a little bit of headroom they probably don't even get that. I'm sure with more power it could damage them.

Played with clean 150w going to them.
Made sure that signals are clean from amp. (O-scope)
Had a little play and 50-55hz is the best they gave me on low end.
They still clipped badly at 150w despite of clean signals.
Owner wanted them like that so left reduced gains a bit.

I truly cannot understand why there is that 'hype' about them. If you play them as midbass, whole sound stage get ruined.

You should try gladen or Ion in your car. Best of both world.

[taibanl]

Why should your soundstage get ruined?

The human ear has very limited ability to localize sounds behind below 200 Hz

There is really no problem with midbass under the seats.

Note: I am not talking about a upper midbass from 2 to 500 Hz

[Wongway]

Yeah, I'm using a completely different setup myself, but even using Jehnert's 8x 6.5's running from 300hz on down, I can't say my front stage is ruined. I will say it's a royal pain trying to tune that front stage from sounding like it's getting pulled down low because my mid/subs are playing as high as 300hz.

When it comes down to it, I really doubt having midbass under the seats hurts. It just creates tuning obstacles is all.

Why 300hz? A bit high IMO. Did don recommend that?

You do have door boards so idk what's optimal for that. I would think 250 max

[jeffb335]

Yeah, most of us with the "conventional speaker setup" are in the 150-200 range...

With apologies, I disagree with you.
Human ear can well localise frequencies as low as 70Hz.
It does ruin sound stage. Why don't you get out of 'conventional box' and try some different frequencies on 'beloved Jehnerts'.

Well you are getting the point.
Play with your crossover and you will be amazed how sound stage alters by simply changing crossovers frequencies.
I had P99RS pre-amp unit in my car and its like having a sound lab in your car....done so much and learnt so much.
Problem is that when you come and share things here, people start challenging you for no reason.
Be open, be flexible and experiment!!!!

I did! I just went the other way with it!

But like I said, I think ruining your soundstage is a bit harsh. It might be a bit of a tuning nightmare, but I still think it's harsh.

As for those that asked 'why 300hz?'
That was my starting point.
I've experimented with 250hz, with no ill effects, and I'd happily experiment more too. I just don't get to have that much time to do so, hehe.

My science might be wrong, but once we get down to levels like 800hz, 500hz, 300hz, etc. our ears are only perceiving phase differences. We calculate phase differences based on how sound hits our two ears. The problem is, at 300hz, what's a 110cm wavelength compared to the 20cm distance in between our ears? That wavelength just blankets our ears right over.

Mak - what have you found as a good lp crossover point for your underseats?

With twice as much power as I have going to them I wouldn't be surprised if you could bottom them out. You are also over their power handling. It's good to have headroom but you aren't actually supposed to use it

It might be cleanest mid bass if you use them 70Hz above.

I would rate ION or gladen better than them as they can play well on both side. Lower end and upper end. They are not true audiophile divers like morel / dynaudio but they are better than Jehnerts and designed to work best in BMW enclosures.
