Alpine DP2-65C Review: The DP2 Two-Way Set With a Soft-Dome Tweeter
Updated: Oct 6
The Alpine DP2-65C is the two-way component set in Alpine's second-generation DP-Series, pairing 6.5-inch woven carbon-fibre hybrid woofers with 1-inch Tetoron soft-dome tweeters and an in-line crossover network. Alpine rates it at 50 W RMS (240 W peak), quotes 90 dB sensitivity and a 60 Hz to 40 kHz response, and lists it as Hi-Res certified. Its India MRP is ₹43,999, above the Type-R R2-S65C and R2-S652 and well below the Status HDZ-65C. It suits buyers who want a well-finished front stage that installs like any passive component set, with the option of growing into a three-way later. Check today's price on our Alpine DP2-65C product page.
Quick summary
DP2 construction: woven carbon-fibre hybrid woofer cones, H.A.M.R. surrounds and cast aluminium frames, with soft-dome tweeters on neodymium magnets.
An in-line two-way network with 0, −3 and −6 dB tweeter settings; Alpine doesn't list its crossover frequency.
The 50 W RMS rating is half that of Alpine's Type-R and Status two-ways, which matters if you plan a powerful amplifier.
The woofer needs a 130.2 mm cutout and 59 mm of depth; the tweeter surface-mounts in a cup with a 43.6 mm cutout.

What sets the DP2 two-way apart
Alpine builds the woofer around a cone of woven carbon fibre blended with what it calls bulletproof fibre, which should give a stiff, light diaphragm, and an H.A.M.R. multi-roll surround for long excursion. The frame is cast aluminium with six mounting points. For the second generation, Alpine claims a redesigned motor for stronger low end and a new tweeter; treat those as the maker's claims.
The tweeter is the bigger talking point. It is a soft fabric dome made from Tetoron, a polyester textile, where Alpine's Type-R sets use magnesium hard domes. Soft domes are generally chosen for a smoother, less forward top end, and hard domes for crisp detail, so this is a question of taste and of how bright your car already sounds. If your windscreen is steeply raked and the cabin is hard-surfaced, a softer dome is often the easier match.
The in-line network and tweeter settings
Unlike the three-way DP2-653, whose network is a separate purchase, the DP2-65C has an in-line two-way network listed in its own specification. Alpine describes it as compact, with air-core inductors and poly capacitors built to its own specification, in a body 51.9 mm wide and 30.9 mm high.
The useful feature is tweeter attenuation in three steps: 0, −3 and −6 dB. In a car that matters. A tweeter mounted close to you on the A-pillar, or firing off the glass, can sound too bright at 0 dB, and stepping it down is often the only tuning a passive system gets. Alpine's pages don't list the crossover frequency or slope, so we can't tell you where the hand-off happens.
Head unit or amplifier?
Because the network sits in the wiring, the DP2-65C connects like any passive component set, to a head unit or an amplifier. The quoted 90 dB sensitivity suggests it is not hard to drive, though Alpine doesn't state the test condition behind the figure.
A set at this price deserves an amplifier, mostly for clean headroom rather than volume. The Alpine S2-A36F gives 60 W RMS per channel into 4 Ω, slightly above the DP2-65C's rating, so set its gains with care. High-pass the woofers so they aren't asked for deep bass, and let a subwoofer handle everything below; with a 60 Hz lower limit, the set benefits from one. A powered subwoofer such as the Alpine PWE-S800 can do that job with its own built-in amplifier. Our guide to why a DSP helps explains the next step if you want time alignment.
What owners and reviewers say about the Alpine DP2-65C
When we checked in October 2026, we found no owner reviews, forum threads or independent tests of the DP2-65C. Alpine's Asian and Australian product pages carry specifications and promotional copy, but no customer feedback.
The closest owner account involves an older relative: a 2023 Tesla Motors Club thread about a kit built around the first-generation DP-653 three-way set, not this two-way. The owner found it much crisper and clearer than the factory speakers on the stock amplifier, while one reply argued the factory neodymium magnets are more energy-dense than the Alpines' ferrite. Treat that as context on the DP family, nothing more.
Alpine's promotional next-generation DP-Series page describes the DP2-65C's external network with air-core inductors and the new Tetoron tweeters. If you run a DP2-65C, we'd like to hear how it suits your car.
DP2-65C vs Type-R, Status and the DP2-653
On paper, Alpine's Type-R sets are the uncomfortable comparison. The R2-S65C (₹32,999 MRP) is rated at 100 W RMS, quotes 88 dB at 1 W and runs 65 Hz to 40 kHz, with magnesium hard-dome tweeters and tweeter levels of −3, 0 and +3 dB. The R2-S652 (₹36,999 MRP) adds die-cast baskets and full passive networks. Both cost less than the DP2-65C and handle twice the rated power. The DP2-65C answers with its soft-dome tweeter and cast aluminium frame (the R2-S65C uses composite baskets), plus a direct route into the DP2 three-way family.
Above it sits the Status HDZ-65C (₹89,999 MRP), with ring-radiator tweeters and a 100 W RMS rating. Within the DP2 family, the DP2-653 (₹48,999 MRP) adds a 3.5-inch midrange per side, and the DP2-35M midrange can turn a DP2-65C into a three-way later, with a DSP doing the crossovers.
Who should buy it, and who shouldn't
Buy the DP2-65C if you prefer a soft-dome top end, you'll run it from a moderate amplifier, and you like the idea of adding DP2-35M midranges and a processor later without replacing the door speakers.
Look elsewhere if you plan to push high power, because the Type-R sets are rated at twice the RMS for less money. Buyers who want owner feedback before spending should also note that we found none for this model yet.
Installation notes for Indian cars
The woofer is 165 mm across with a 130.2 mm cutout and 59 mm depth, so measure your door opening and window-glass travel; many cars need an adapter ring. Damp the door skin and trim while it's open, as our sound damping guide describes, because a resonant door wastes midbass.
The tweeter mounts in a surface cup 59 mm across, which suits dash corners, A-pillars and custom pods; aim it towards the opposite seat. The in-line networks are small enough to tuck behind a trim panel, but keep them out of the door's wet zone and away from rattling panels. VA3 Car Studio in Ghaziabad offers professional installation if you'd like it done properly.
Price and where to buy
The DP2-65C carries an MRP of ₹43,999. We often sell below MRP, so see the current offer on the DP2-65C listing. Every set we sell is a genuine Alpine product.
The bottom line
The DP2-65C is a well-built passive two-way with a soft-dome tweeter, adjustable tweeter level and a cast aluminium frame. Its weak point is the comparison with Alpine's own Type-R sets, which cost less and are rated for twice the power. Choose it for its tweeter character and the DP2 upgrade path, and power it sensibly.
Alpine DP2-65C FAQ
Does the Alpine DP2-65C come with a crossover?
Alpine lists an in-line two-way network in the DP2-65C's own specification, with 0, −3 and −6 dB tweeter settings, air-core inductors and poly capacitors. Unlike the three-way DP2-653, no separate network purchase is listed for it.
Can the Alpine DP2-65C run on head-unit power?
It can be wired to a head unit through its network, and Alpine quotes 90 dB sensitivity, without a test condition. For a set rated at 50 W RMS, a modest amplifier gives cleaner headroom, especially with the AC and engine noise of Indian traffic.
Should I choose the DP2-65C or the R2-S65C?
The R2-S65C costs less at ₹32,999 MRP, is rated at 100 W RMS and uses a magnesium hard-dome tweeter. The DP2-65C has a soft fabric dome and a cast aluminium frame, is rated at 50 W RMS, and links into the DP2 three-way family.
