Dayton Audio ND105-8 4" Aluminum Cone Midbass Driver 8 Ohm
Dayton Audio ND105-8 4" Aluminum Cone Midbass Driver 8 Ohm is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Size doesn't always matter. Deep Bass can come from small drivers..I'm a recording/ live sound engineer, and have been a cabinet designer/builder for over 30 years, and have come across many drivers that has impressed me, but none like the ND-105 8's. I bought them almost a year ago, and just now was able to work on a project for them. I designed and built cabs at .35 ft (after displacement) with a 1.75" port 4" long (tuned to 64.1 Hz) along with some internal SWM construction, and found these drivers to go WAY below their low end specs. My RTA show them coming in at just below 46 Hz., and VERY flat. I have 2 cabinets built that I am enjoying every day as SUBS (125 Watt Sub Amp turned down)! NO JOKE! SUBS! The drivers low end is soo clean and flat in my enclosures, that's it's sick. Kick drums have a very solid punch, and all with a very defined, and clean bass guitar. again, this is as a SUB!! I have ran Full-Range tests as well, and have just as impressive results as well. Besides the music ability, the HT Sub watching movies was just as impressive. Ohh, My same cab design (with minor SWM changes for 2-way), would work beautifully as a 2 way bookshelf, or satellite as well. Just add a ND28F-6, a crossover, and it's done.IMO the best impressive driver I HAVE EVER TESTED, AND USE. Now to complete the enclosures knowing they are worthy..I only wish they had more power handling capability, and didn't require so much air space to achieve their best overall sound.BASS players.. I have a cabinet designed for 8 of these bad boys in a single cabinet for on stage,.... SICK..Cheers, Rob Bender II, SoundManRob Tech.Designer/Builder CAE (Custom Audio Enclosures)

Rated 4 out of 5 by from Great fit for the applicationWent out on a limb with these as I was replacing some rare 10 ohm speakers in an early 4th gen Pontiac Firebird. Not sure if anyone else tried them. Turns out it was all good! They seems well made and are lightweight as noted. Their square frame is a bit smaller than the stock, but you can make it work with two custom revit holes. There is a thin rubber seal under the mount to prevent vibrations. The original speakers seem slightly louder but certainly blast distortion all over. Not so with these - VERY clean sounding and even hit some nice mid-lows. Check out the rated frequencies.I see that there is a 4 ohm one of these if you need - do a search. Overall great! Not to mention lightning fast shipping from Parts Express. Mine haven't been tested by time yet but I'm sure they will do well.

Bookshelf speaker using these along with a vifa 1" silk dome tweet. Part # 640-1040. What would be the best dayton audio two way crossover to use

Asked by: chicarico
Unfortunately none of the Dayton crossovers will work with a 4 ohm tweeter load. I would recommend contacting our tech support for other alternatives to the crossover, 800-338-0531 x1 or tech@parts-express.com.

Can this be used in an small open baffle setup for near field ?

Asked by: savaemako
Yes these will work fine in an OB application although you will be fairly limited on the amount of bass you will get.

Wattage difference ?

Hi i am thinking about buying these nice looking speakers. But does anyone know if these would be compatible in a bookshelf with another speaker that has a much higher wattage ? Actually of 360w !Do speakers need to be of a close or similar Wattage if they are to be in the same cabinet ? Would the volumes greatly differ then if the power requirement differs ?
Asked by: Donal
It's power handling may or may not be compatable, hard to tell without knowing what it is being compared to specifically. I'm inclined to believe that with a "360w" rating in a bookshelf style speaker, that it is likely a relatively inexpensive shelf type system and that the rating is a max output rating, likely delivering not near half that rms, so it may not be an issue.The cabinet size should be close to the recommended sizes listed in the specs above. Feel free to measure your cabinet, internal space/dimesndions, and compare.The main things to consider in your situation would be the impedance of the driver you are replacing (should be the same) and that the enclosure size is the same.This driver's efficency is 83 db, which may be less by 3db or more than the driver you are replacing, so the output may be less.

ABC box question

Assuming I want to get deeper bass out of this driver and willing to take up a little more space (not practical I know) but I want to build an abc box for this and use two tuning frequencies... Obviously building a huge box tuned real low would just do nothing but destroy the driver or basically make it free air but using an abc box I could possibly boost the low end a little yet keep the driver under control with the secondary chamber tuning it... Don't have a program to do model it... Feel me in
Asked by: 12vaudio
There is a free program out there to model boxes. Search for linearteamwinisdpro. It does not model Aperiodic Bi-Chamber boxes however you can model a single ported box with two ports to your desired tuning frequency. Divide the volume you get into 1/3rds. Two-thirds will be where you mount the woofer and first port. The other one-third will house the second port. A third port will connect the two boxes. Make sure you account for port and driver volumes and make your boxes larger accordingly.Since you are already planning on a larger box, you could consider a ML-QWTL or Folded Horn. I have two of these drivers and plan on a Mass Loaded Transmission Line, once I get my 3 or 4 other projects done. I build a MLTL for a friend for christmas with some 2" drivers and was blown away by the bass preformance (f3 in the high 40s).Also check out PE Tech Talk forum, a lot of great help and less restrictions then the Q&A postings.

Are these a drop in replacement for the Realistic (Radio Shack) Minimus 7 woofer?

or would your Goldwood GW-204/8S 4" Shielded Poly Woofer 8 Ohm drivers be better suited for that task?
Asked by: Flintstone
According to our customers' feedback and reviews, the Goldwood woofer you referred to is closer to being a "drop-in" replacement for the Minimus cabinets.
