And I challenge you to prove me wrong. Conditions...because we all know "best" is subjective...

1) State the market price of the pair of drivers you think are better. Used internet prices don't count.

2) State the location, passband, and slope the drivers are playing as well as any EQ work done to them.

3) Post picture of the deadening job done within at least 2' of each speaker. I'm assuming most are door installs, but could be different.

And just so you know, this (http://tymphany.com/830667) is the driver in question.

That is all. Have a nice day......:)

You think you're better than me!!?!?!

Don't have to be no door install. As you know, I have trouble with 4" drivers in my kicks. :emb:

You consider them better than the exclusive's then. Are you talking 3-way, and
what crossover point?

8" midbass. I'm pretty sure he means dedicated midbass.

i wouldn't run above 350hz to these 8's.

above that would go to good midranges

looks like they can play higher than that...

Hmm, Ive never heard these, too bad they are 8 ohm as well. I dont have enough power :mad:

And i think those would do fine above 350 as well..

I'm sure your right, I was just wondering how high he was taking them.

I'm talking dedicated midbass in a 4-way active set up.

Xover pt depends on install, tuning, location, etc. So, that's for you to tell me! Hence, the challenge. :)

Not trolling, don't need to. I've personally used some of the "best" drivers for this job so I'm comfortable offering this up. So put up or shut up. Easy.

What's interesting is that this driver is listed as a subwoofer by Peerless, yet it's the latest and greatest of the IB midbass's? I haven't heard much if any bad feedback for it as a dedicated MB, so can it be beat or what? Lets see it! :)

i got two 6.5's, going to be 2x per side soon wehen they get back in stock

love the sls's. they can play up to around 800hz, but i dont know if they're the "best" for IB.. but still pretty **** good. and would highly recommend them

FoxPro5
04-17-2009, 10:33 AM
Dual 6.5's sounds brutal, man. Are they backordered from Peerless then or what?

Don't know about those, but the 8's perform excellently IB...given you get them on a sturdy baffle and keep it from resonating in the passband you want it to play. They definitely rival the Legatia 8; and for the price *censored* .... that's what this thread is all about. :veryhapp:

The SLS 6.5 can hold it's own, best 6.5 I've owned playing from 250hz-40hz.

A pair of those should IMO match the output of a single SLS 8.

Maybe not output, but could possibly sound better than a single 8". I have this theory that lower xmax woofers for this purpose sound better than higher. :uhoh:

yeah but the 6.5's are also 4 ohms.. the 8's are 8.

FoxPro5

Don't understand your point. Wire the 6.5's in series to show the amp an 8 ohm load?

Side by side, the 4 ohm 6.5" compared to the 8 ohm 8" might be 1-2 dB greater SPL depending on where they're crossed. Certainly nothing to be at all concerned about.

Etac
04-19-2009, 11:36 PM
oh i wasnt talking about what you said, i was just saying in general they are 8 ohms..

i just meant the 6.5s would be easier to power at 4 ohms, or 2 in a dual setup.

and you're right the two 6.5's would come close to an 8... without tuning the single 8 would play "flatter lower.." dont know how to word it really.. the 6.5s would prolly play just as low but raise more steeply as they get higher and then thats where you would see the increase in spl, but like you said, not notciable. i might be wrong tho

and too the OP's orignal point.. for the money they are hands down awsome.. their magnet is fkn huge tho and basically as big as the cutout.. (well the 6.5's)

and i just found out today one of my amps is broke so my dual setup might have to wait a little longer =\ im actually gonna have to run a passive threeway for now. ordering the parts for them tomorrow

edit: the reason im doing two 6.5s mainly and not two 8's is because of space. i could fit a single 8.. but i dont wanna power 8 ohms.. and it doesnt matter really if i can get below 60hz because no matter how much power my doors would never play "low" without being sealed with cement lol.. so two 8s besides space, would be overkill

FoxPro5

The 6.5" is 86.5 dB and the 8" is 87.2 dB (2.83V/M).

Well if you're caught up on the 4 ohm vs 8 ohm and halving or doubling the power type of thinking, then my point is that it's not something to be concerned about. In other words, "powering 8 ohms" isn't like you'll get half the output than you would "powering 4 ohms". It just doesn't work that way. :cool:

You're better off, as you alluded to, being concerned with constructing a proper baffle and maximizing the install than the nominal impedance.

I've never heard these in person...but the best dedicated midbass drivers I heard were some Morel's.. I dont remember the model.. but I couldn't imagine anything sounding better than these drivers.

They are probably much more expensive that the Peerless SLS's which would render my argument rather void but just based on sound.. those sounded absolutely amazing.

Etac

The 6.5" is 68.5 dB and the 8" is 87.2 dB (2.83V/M).

well i didnt think it would be "halved" but i did look at it as a loss, and now that i do think about it.. the more i realize your right, the more i realize how it'd prolly be more like 1.5 or 2 db's "at most".. the your ear probally wouldnt hear much of a difference anyway. hmm

maybe i will run a set of single 8's ;)

what's with this talk about 6.5"s and 8"s... they're for kids. :)

FoxPro5
04-20-2009, 12:30 AM
Oops, made a typo there. Meant to say "86.5 dB" not "68.5" .... that would be totally different. :)

If I were you, I'd look at the FR graphs between the two between the frequencies you want them to play. They are almost the same from 50 - 250hz with the edge going to the 8"...maybe. In your car, however, the response will be determined by what I mentioned earlier. So, given that you do put adequate work into the doors, then either option should work very well.

My inclination is the dual 6.5's would give more of a solid "kick" whereas the single 8's would play a bit lower with more "uumph" and sound more like a sub by filling out the cabin. You're talking 258 cm^2 total cone area on the dual 6.5's vs 204 cm^2 on the 8" with only a .5mm xmax between the two.

Well you really don't want too big of a MB because then the front fill is too slow compared to the speed of the rear stage. It's like 20" is more front SQ vs maybe 12" rear SPL unless 8" per cube of VBA is installed (must be Canadian air.) It's really complicated, JB....don't loose touch with reality. :crap::p:

Well, you know I wont argue this statement. Still the best driver I've used for the money. Although the Fountek FR88's are sitting here waiting to be tested...

There really is no reason to spend more money on an inferior mainstream "brand name" product. These SLS' absolutely smoke everything else. Hell, I'd say you would have a hell of a time finding something better for 4x the price. They are just that good.

That statement alone makes this thread completely worthless because best IS subjective. But money no object (as title of thread says) I'm about 99.999% sure there are better drivers out there to handle MB duty.

It all depends on your goals. This is a great budget driver with a high price/performance value but is far from the "best" unless defined by value alone, which again is a serious debate over the validity of that statement.

I really think a RS225 would outperform this, in my opinion.

I believe you would be wrong (about the RS225). While it is a great value driver, if you want low extension, an excellent motor and low distortion, the SLS8 bests the RS225.
The RS225 would be far better for use as a combo midrange/midbass driver, but not used as a dedicated midbass driver.

It depends on what you prefer.

I love the RS drivers, bass and everything. And again, this is a stupid argument because best is subjective. SLS8 might have more output but I prefer the sound of the RS225.

Again, moot point trying to argue in this thread anymore given the nature of "best."

I'm loving my dayton 8's running from 40hz - about 200hz or so (waiting for sub amp). I think they sound great and can handle the 300wrms I'm sending them pretty well, even at loud volumes on bass mekanik tracks they take a good while before they start to smell. I had the SLS 6 1/2's and they were really nice too though. I think the depth of the SLS 8 would be more of a problem for me so I'm content with the Daytons. Maybe I'll try out the SLS 8's later on especially since I don't mind my window not being able to roll all the way down.

Fitting them is usually the biggest problem. They're definitely deep. But well worth it if you can make it work. 300watts on these would really get them moving.

its not a dedicated midbass.

My friend wants to add a 8inch midbass to his germs with a 4x chn amp


chn 1 & 2 germs (passive)
chn 3 & 4 SLS 8 ( im still looking for a 8inch for him)



don't ask me why his doint it

If you guys want good midbass stop looking at low effeciency high excursion drivers. 80hz and up is almost always effeciency limited, not excursion. At 150hz where alot of the main midbass kick is, mids run out of power handling before they reach xmax. Big drivers running down to 40hz is just giving you decent midbass that extends very low into the sub-bass region. Lots of power and 90db+ of effeciency is where it's at for drums.....
