Dayton Audio RSS265HF-8 10" Reference HF Subwoofer 8 Ohm

The Dayton Audio Reference Series subwoofers take the quality and performance of the much acclaimed RS line into the subwoofer realm. As with the rest of the Reference Series, the main focus of the RSS265HF-8 10" subwoofer is ultra-low-distortion. Second, third, and intermodulation distortion are kept extremely low by utilizing three short-circuit paths within the motor structure. A durable aramid fiber spider and extensive venting throughout provide quiet and uniform excursion. The black anodized cone, rubber surround, and custom basket give this driver a unique, high-end look. Choose this High Fidelity (HF) version for home speaker systems when your priority is clean, low bass and you are not restricted by cabinet size.

Dayton Audio RSS265HF-8 10" Reference HF Subwoofer 8 Ohm
Dayton Audio RSS265HF-8 10" Reference HF Subwoofer 8 Ohm is rated 4.75 out of 5 by 4.
Rated 5 out of 5 by from Perfect handoff to small speakersI purchased this driver for a subwoofer project to hand off to a 5.1 Orb Mod-2 setup. The well respected, but non-Orb, commercial sub I was using would not go high enough. My Orb's have an Fs of about 200Hz (according to DATS). The commercial sub rolled off around 160Hz at the high end. For home theater (the predominant use) it performed fine. But for music: another story. Some songs had a noticeable gaping hole in the response while others just didn't sound right.This driver, forward firing in a 2 cu.ft. sealed truncated pyramid enclosure and paired with a 300W external amp with the crossover bypassed, seems magical. The bass is very well controlled, not boomy at all, with good extension into the mid 20's (room gain & small amp low freq boost). The home theater amp handles the crossover (~210Hz). Listening to music is much more pleasurable. And movies don't disappoint. This driver can ruffle your pant legs!This project also served as a proving ground for this driver. I plan to purchase another one for use in a 2.1 setup built strictly for music. 5.25" mid-bass with planer tweeters.My only complaint is that the outer diameter is too large to allow you to use, as intended, the Parts Express steel mesh 2-piece grill. I didn't want the more 'industrial/pro-audio' type of grills so I deeply countersunk the driver and mounted the grill in front of the the driver with the mounting ring effectively flipped over (mounting edges sticking out from the driver rather than wrapping the driver frame.) A pain, but it ended up nice. See pic of front of unit. In retrospect, the high surround (to accommodate the Xmax) probably wouldn't have allowed the use of the mesh grill even if it fit the outer diameter--the cone may have hit the grill!Overall I'm very pleased and look forward to using this unit an my next project.

Rated 5 out of 5 by from Great Product replacement for My Klipsche SubHits hard in sealed enclosure. Just as good quality as original

Rated 5 out of 5 by from Extremely Pleased! Replacement SpeakerWent out on a limb and bought this speaker to replace a fried Paradigm sub speaker. I expect a lot out of my equipment and this new Dayton rocks. It totally blows away the stock speaker that came with my original Paradigm sub box and works great with the integrated power supply built in to the sub box. The magnet alone weighs about 12 pounds more than the original speaker and fit into my sub box perfectly!

Rated 4 out of 5 by from Overall, Gets the Job Done when used with a dedicated Sub AmpVery good X max with high Mms. Therefore a respectable LF cut off freq. Works well as a single unit , better as (2) together in parallel. Sealed enclosure is the best choice with about 1 cu ft per. Forget about using above 200 Hz due to prominent ringing modes above 500 Hz. This means a dedicated SW amp(not less than 300 W) with adequate Low Pass attenuation above 100 Hz. not less than 12 db/oct. Would like to see higherBL which can be accomplished by a few more turns on the V/C.Ideally, this unit would be replaced with a neodymiumversion using a 3" V/C

Will this be a good match for a Boston Acoustic A100 speaker system?

Asked by: Bill129
I would not recommend this as a replacement for that speaker system. This is designed to reproduce sub frequencies only and will not handle a crossover high enough to match with a tweeter. Something like a GRS or Goldwood 10" will be a great match for the enclosure you have and be better suited for that speaker system.

What size closed box - and why is this product best in a closed box?

I am planning on using this in a 3 way closed box. I understand it is "best" in a closed box. I do not understand how this can be determined from the specifications. Also, I was planning on about a 3cuft box, but some comments and answers suggest that is a large box for this speaker. Will 3cuft be detrimental to the characteristics of this speaker? Is that based on Vas of 1.82cuft? Should a closed box always be below the Vas?Have I asked too many questions???!!
Asked by: mcmillinamps
Yes this is best suited for a sealed box around 1.2 cubic feet being "optimal". There are a combination of specs that determine box type, Qts being one of them. Usually speakers with a Qts of .4 or higher are better suited for sealed enclosures. Your best bet is to put a divider in the box to create a smaller volume for the woofer, anything between 1.2 and 1.5 cubic feet will be best and give you a nice low in room response into the upper 20's. The Vas is only slightly related to box volume but there is no rule of thumb based on the number alone.

Does it need an amp for itself

If it's part of a stereo 3-way loudspeaker (tweeters, mids and subs) Does the subwoofers need amps for themselves or the power from the main amp is enough to drive the subwoofers and all the other speakers?
Asked by: jo prev
You do not need a seperate amp, however this subwoofer is fairly low sensitivity so you will most likely need to pad down your mids & tweeters to match the output.

Inquire about this subwoofer in a ported box

Single 10"Front long rectangular vented sub boxMounting Depth: 13"Air Space: 1.14 Cubic FeetVented EnclosureDimensions: Width 16" x Height 12" x Depth 14"
Asked by: The1Don
When you already have a box you limit your use of drivers. You can adjust or seal the vent. If you look at the Speaker Builder tab and then woofer selection guide - you can narrow down some choices. Whatever your choice, including those not on there, you need to search online for a "box calculator" where you plug in the driver specs. It will then give you performance curves for sealed or ported and if ported the length and diameter, along with box volumes... It's a fun project - albeit a bit time consuming until you find exactly what you're looking for.

best plate Amp?

best plate Amp? for one or 2 in the same box. I guess would use a single 4 ohm if using only one. In a small sealed home design for music what box size range would be ideal?
Asked by: sumthinsmart
I would use the bash or dayton plate amps you could use to 300 or 500 watt bash amps, or the 250 or 500 watt dayton amps with this sub. 1 cuft sealed looks to be a good size for the enclosure. The 500 watt amps will give you more headroom, but in 1 cuft be careful because they can push this driver into overexcursion.
